BY ALEXANDER WINCHELL. With the view of collecting facts bearing upon the determination of the geological age and equivalents of certain ferruginous sandstones in the lower peninsula of Michigan, which I have provisionally designated the Marshall Group,* I visited several of the neighboring States during the past summer, for the purpose of examining the principal exposures of strata supposed to occupy nearly the same horizon. At Burlington, Mr. C. A. White accompanied me in all my examinations, and enabled me to procure nearly a complete suite of the species of that place described by Shumard and Hall, but more espe- cially by himself and Mr. R. P. Whitefield.f Besides the recognized species, I obtained from Mr. White, or by his assistance, several undescribed forms. Subsequently Mr. White greatly increased the number of unknown species by his discoveries at exposures hitherto but little explored. The whole collection of new species, together with his own observations thereon, has been kindly placed in my hands for investigation ; and the following paper is the result of this study. The number of new species herein described is fifty-niae, and the number now first identified, ten. The number of species previously known from these rocks was sixty-six, J a total which is now raised to one hundred and thirty-five. The richness of this locality in fossil species is well worthy of note. To the one hundred and thirty-five species from the yellow sandstones must be added three hundred and seven species from the overlying Burlington lime- stone, making a grand total of four hundred and forty-two species from a single locality. It ought not to be forgotten, that this wonderful result has been developed mainly through the industry and skill of a single individual, Charles A. White, who, during eight years of his residence in the locality, has collected the types of two hundred new species and six new genera. A consideration of the general conclusions deducible from the study of the palaeontology of the rocks of the Western States supposed to occupy the horizon of the Marshall Group of Michigan will be hereafter presented. Suf- fice it to say, on the present occasion, that no one can glance over the list of species described here and elsewhere from these rocks without admitting that the ensemble bears a very close analogy with that of the " Mountain Limestone" of the Old World, and raising the inquiry how the equivalent of the old red sandstone can lie on the top of such an assemblage of strata. Descriptions of New Species and Genera. LEPTOPORA, n. gen. Etymology, As/ttcc, shallow andirs/a, a cell. Corallum occurring in thin discoidal masses; cells very shallow, crowded, polygonal, separated by a common cell-wall, which is vertically striated ; interior of cells filled with a finely vesicular tissue; cups polygonal, con- cave, elevated in the centre, and displaying numerous radial lamellae. * See " First Biennial Report" of the Geological Survey of Michigan, 1860.

White and Whitefield. _ T [Jan. NATURAL SCIENCES OF PHILADELPHIA. Leptopora typa, n. sp. Polypary subcircular in outline, and slightly con- vex on the general surface ; composed (in the specimens examined) of 25-30 rather large cells, of which the internal ones are hexagonal, and the peripheral rounded exteriorly ; margins of cups strongly elevated ; radial lamellae about 20. Diameter of mass '72 -,* diameter of the cells about -14, and their depth about -07. In a specimen whose diameter is 1-27, tbe diameter of the cells is -22. Ranges from the oolitic bed No. 6 into the base of the Burlington lime- stone. This singular coral is not as well known as is desirable. Though discoid, it. does not seem to be encrusting. No diaphragms or communicating pores have yet been detected. TREMATOPORA, Hall. Trematopora? vesiculosa, n. sp. Corrallum delicate, terete, branching, celluliferous on all sides. Cells arranged in spiral and often longitudinal series ; cell-mouths oval, slightly elevated on the lower margin, the longitudi- nal series more or less separated by a straight or flexuous, sharply-raised carina. Surface between the cell-mouths imperforate, but the substance of the corallum beneath is irregularly vesicular. No solid axis exists, the cells ap- pearing to ascend and diverge gradually from an imaginary axis. Diameter of stem about -05 ; length and breadth of cell-mouth -02 and -01 ; distance between the cell-mouths in the spiral series -01. In some specimens the cell-mouths are somewhat more widely separated. Base of the Burlington limestone and in the fine grained sandstone of Ohio. Trematopora ? fragilis, n. sp. Corallum delicate.branching.terete or slightly compressed at the bifurcations, celluliferous on all sides. Cell-mouths minute, oval, somewhat remote, not disposed in regular series, more approximate in a transverse than in a longitudinal direction. Intervening surface imperforate ; the substance immediately beneath minutely cellular. Least distance between contiguous cell-mouths about equal to their transverse diameter; greatest distances two or three times as great. The absolute di- mensions of the cell-mouths are less than in the last species. Base of the Burlington limestone. The two species above described are only provisionally referred to Trema- topora. They belong to a group often ranged under Millepora and Ceriopora, but apparently without sufficient reason. The assemblage of branching (or sometimes foliaceous) corals without septa or lamellae, ranging from the lower Silurian into the Carboniferous limestone, seems to be but imperfectly understood; and the generic and even more fundamental relations are in a state of very unsatisfactory vagueness and confusion. LINGULA, Bruguiere. Lingula membranacea, n. sp Shell flattened, quadrate-ellipitical, nearly as broad near the beak as at the same distance from the anterior margin ; length nearly equal to twice the width ; lateral margins slightly curved ; beak scarcely elevated, near the posterior margin, but with a narrow belt behind it. Shell substance membranaceous, marked externally by very delicate, regular concentric lines. Length '50 (100); breadth in the middle -32 (64) ; breadth at one-fourth the shell-length from posterior end -28 (56); breadth at same distance from anterior end -31 (62). Differs from L. concentrica, Hall, from the Genesee slate by its subequal * The measurements in this paper are given in inches. Where one number is followed by another in parenthesis, the latter is the relative measurement the dimensions which is generally the greatest being assumed 100 1863.] 4 PROCEEDINGS OP THE ACADEMY OP width at the two extremities. A similar undescribed species occurs in the " fine-grained sandstone" of Ohio. DISCINA, Lamarck. Discina patellaris, n. sp. Upper valve circular, elevated, patelliform, with a subcentral beak, from which the surface slopes in right lines to all parts of the margin, except a barely perceptible concavity down the posterior slope. Surface (of cast) with feeble concentric strise. Diameter -90 (100); height of upper valve -33 (37); The length appears to be a very little greater than the breadth, but the specimen is slightly defective posteriorly. This species recalls D. Alleghania, Hall, of the Chemung Group, but the apex is more central, and the concentric lines less lamellar and regular, and the shell, so far as known, is smaller. PRODUCTA, Sowerby. Producta ? parvitla, n. sp. Shell very small, semi-elliptic or nearly semi- circular in outline, with a hinge-line equalling the greatest width, or a little less. Ventral valve ventricose, with regular, though slightly diminishing curvature from beak to anterior margin, describing an arc of about 180 ; beak elevated above the hinge-line and incurved over it; flanks regularly convex, abruptly flattened and auriculate at the hinge extremities. Dorsal valve unknown. Surface ornamented with small, rigid, continuous, radiating ribs, which on the sides increase by implantation. Length from beak to anterior margin -38 (100); width -31 (82); depth of ventral valve -23 (61). The prevailing dimensions are less than the above. _ Amongst Products of similar age the miniature size of the present species renders it at once distinguishable. The specimens look like pygmy examples of P. cora, arcuata or pilciformis. Producta Martini, (Sow.) de Kon. (P. sernireticulatus, Martin.) In the wide range of characters admitted into this species, as defined by de Koninck, there is little doubt that the Burlington specimens would be embraced. Although most of the American species of Producta formerly identified with European types have subsequently been separated, P. Martini (or semireliculatus) is still admitted to exist in our coal measures ; and it seems probable that its first ap- pearance dates considerably further back. Ranges from the bottom of the Yellow sandstones into the Burlington limestones. Producta speciosa, Hall, (Tenth Ann. Rep. Reg. N. Y., p. 176). Several casts of this Chemung species present the appearance of being inside views of very concave dorsal valves ; but no internal structures are visible. The beak is flattened, and not elevated above the hinge-line, which is somewhat shorter than the greatest width of the shell. The other characters also agree. STROPHALOSIA, King. Strophalosia ? nummularis, n. sp. Shell of medium size, circular, trunca- ted by the hinge-line. Hinge-line (generally much) shorter than the greatest width of the shell. Ventral valve comparatively very shallow, regularly arch- ing from the anterior side to the vicinity of the beak, which is obtuse, not in- curved and not elevated above the dorsal margin; surface depressed each side of the beak ; area apparently present, but very narrow. Dorsal valve discoid, with abroad, shallow umbonal depression, which is bounded on the two sides by lines diverging from the beak at right angles with each other, or nearly so ; beak depressed, furnished with a small bifid cardinal process or boss, which lies in the plane of the valve and projects beyond the hinge-line ; each branch of the boss continued internally in a low vanishing ridge, which is turned out- wardly into the position of a socket ridge, but without the socket behind it ; [Jan.. NATURAL SCIENCES OF PHILADELPHIA. 5 median septum a low ridge appearing a short distance from the beak, and disappearing toward the middle of the valve; vascular imprints sectoriform reaching half way to the midvalve, separated from the median septum bj a faint ridge (occlusor apophysis ?) on each side. External surface of both valves with numerous concentric lamellar striae and innumerable little pits which give the impression a finely granular appearance ; pits more scattered and deeper toward the anterior margin. Internal surface (of dorsal valve) exhibiting concentric lines and innumerable raised points, apparently corres- ponding with the pits of the exterior. Length -82(100); width 1-06(129); length of hinge-line -55(67); length of cardinal process -04 (5) ; depression of dorsal valve -04 (5). Depth of ventral valve -15, with a length of -76. Another dorsal valve has a width of 1-46 and a hinge-line 1-22 long. Tttis anomalous species has more the form of an Orthis or Strophalosia than a Producta. But there is no positive proof of the existence of spines, and the somewhat doubtful existence of an area in either valve furnishes only unsatis- factory grounds for referring it to either genus. At the same time it is difficult to understand how the externally projecting cardinal processes of the dorsal valve could be used without a fissure (and area?) in the ventral valve in which they could move. In view of all the facts, I venture to refer the species with a query to Strophalosia. Should the reference prove correct, it will be, so far as 1 know, the first identification of this genu3 in American rocks. CH0XETE3, Fischer. Chonetes mdlticosta, n. sp. Shell of medium size or larger, semicircular, with the greatest width along the hinge-line. Ventral valve depressed-ventri- cose, more or less flattened toward the hinge extremities ; with a barely per- ceptible mesial sinus reaching two-thirds the distance to the flattened incon- spicuous beak; spines two (possibly three) each side of the beak, nearly at right angles with the hinge-line, of medium length, rather stout, the first mid- way between the beak and cardiual extremity, the second midway between this and the same point; area extremely narrow. Dorsal valve shallow, concave, with a depressed mesial fold extending nearly to the beak ; socket plates very divergent ; occlusor scars forming a very small elleptic pit near the beak. Ex- ternal surface of each valve bearing 180-200 fine, subflexuous, radiating stria?, which increase dichotomously at all distances from the beak, and some:imes also by implantation. Surface of cast rather remotely punctate. Length of hinge-line -82 (100) ; length of shell -50 (61); convexity of ven- tral valve -12 (14). In most specimens the last measure is relatively less. Ranges from the base of the yellow sandstones into the base of the Burling- ton limestone. Intermediate in size between C. Logani and C. Fischeri of Nor- wood and Pratten. It possesses a greater number of radiating striae than C. lllinoiensis of Worthen . Chonetes Illinoiensis, Worthen, (Trans. St. Louis Acad. Nat. Sci., i. 571 ;) C. Logani, Hall, (Iowa Rep. p. 598, pi. xii. fig. 1, a-e and 2,) not C. Logani, Nor- wood and Pratten, (Jour. Acad. Nat. Sci. Philada., [2] iii., p. 30, pi. ii. fig. 12, a, b, c.) Some confusion seems to exist among the species of Chonetes just mentioned. C. Logani was described "from the middle portion of the mountain limestone series," at Burlington, Iowa, and characterized as having "about 30 rugose ribs."/ The figure agrees with the description. Prof. Hall subsequently described a species from the Burlington limestone, of Burlington and Quincy, which he referred to C. Logani, Nor. and Prat., though, among the characters, he assigns to it " 100-120 or more fine rounded dichotomizing striae." Still later, Mr. Worthen, conceiving this form to be specifically distinct, gave it the name of C. lllinoiensis, remarking that it " is restricted to the crinoidal beds of the 1863.] G PROCEEDINGS OF THE ACADEMY OF mountain limestone," being abundant at Quincy, 111., and intimating that Nor- wood and rratten had erroneously assigned their species to the mountain lime- stone, in consequence of supposing all the Burlington rocks to belong to that series. The " middle portion of the mountain limestone series," however even as then understood would be found far above the yellow sandstones at Burlington. Moreover, in referring C. Fischeri to these sandstones at the same locality, they place them " at the base of the mountain limestone." It seems clear, then, that C. Logani belongs to the Burlington limestone, but that never- theless, the species described by Hall cannot be the same, and has been properly separated as C. Illinoiensis. The latter species, however, contrary to Mr. Wor- then's opinion, occurs frequently in all the beds below the Burlington limestone having a range co-extensive with that of C. multicosta. SPIRIGERA, (d'Orbigny,) Billings. Spirigera corpulenta, n. sp. Shell of medium size, extremely ventricose, varying in outline from oval to orbicular-oval. Ventral valve depressed from the anterior margin to the summit of the greatest gibbosity, which is two- thirds the distance to the beak ; anterior margin rather deeply sinuate, or very slightly so, sinus soon disappearing in a mere flattening of the valve, or trace- able backwards, in a narrow shallow groove, as far as the middle of the shell ; umbonal region extremely inflated ; beak abruptly turned toward the opposite valve, not produced, truncate, circularly foraminated. Dorsal valve extremely ventricose near the anterior margin, slightly elevated in a mesial fold traceable to the most gibbous region, which is less than half way to the beak ; surface depressed between this region and the beak ; beak inconspicuous, covered by its fellow. External surface of casts strongly marked by numerous lamellose wrinkles of growth. Length -80 (100); breadth -70 (81); depth of both valves -58 (72). Breadth and depth of another specimen -75 and -68. The aspect of typical specimens is exceedingly unique. The great gibbosity of the rostral region of the ventral valve and the anterior region of the dorsal, causes the line of junction of the two valves to pass diagonally from the an- terior to the posterior region. The lateral edges of the two valves, moreover, lie in the same plane, so that the sides of th* shell present a regular convexity, like the dorsal and ventral surfaces, and the lines of growth of the two valves, diverciDg from the postero-lateral region complete the illusion of a dorsal or ventral surface radiately ribbed. SYRIXGOTHYRIS, n. gen. Etymology, ivpiy?, a tube and BufU, a window. Shell with an elongated hinge-line. Ventral valve with a mesial sinus, a very broad area, and a narrow triangular fissure closed toward the apex by an external e'onvex pseudo-deltidium, beneath which, and diverging from it, is another transverse plate connecting the vertical dental lamellae, arched above, and beneath giving off a couple of median parallel lamellae, which are incurved so as to nearly join their inferior edges thus forming a slit-bearing tube, which projects beyond the limits of the plate from which it orginates into the interior of the shell. A low median ridge extends from the beak to the anterior part of the valve. Dorsal valve depressed, without area, with a distinct mesial fold. Shell structure fibrous. The elevated ventral and deficient dorsal area of this genus, not less than its external pseudo-deltidium, of one piece, ally it to Cyrtia, Dalman, and Skenidium, Hall. It is not known whether the arms were furnished with calcareous spiral supports, though the general aspect of the shell is that of a Spirifera. The shell substance is impunctate in all conditions and under high powers. Some difficulty exists in deciding on the homology of the transverse plate and fissured tube which characterize this genus. In the ventral valve of Merista, [Jan. NATURAL SCIENCES OF PHILADELPHIA. i especially of the type of Camarium, Hall, an arching lamella arises from the basal portion of each dental plate, and the two unite in the mesial line of the valve, forming a structure which Prof. King, before the separation of this genus, had styled the shoe-lifter process, arched in front, and attached to the bottom of the valve behind. In Spirifera granulifera, Hall, a horizontal transverse plate stretches across the middle of the beak of the ventral valve, connecting the dental lamellae where nearest approximated by their inward curvatures, a stucture which probably represents the pseudo-deltidium of certain Spiriferse, but not of Cyrtia. Beneath this plate, the ventral medium septum assumes the form of a tapering cone, resting with its base filling the cavity and having the anterior part of the upper side marked by a longitudinal groove or slit, while the posterior part sends up a small vertical plate to the transverse plate just mentioned. In Syringothyris, the transverse plate equally connects the dental lamellae where most approximated, and is somewhat arched upward, as in Me- rista, but it does not join the bottom of the valve as in that genus, nor is it connected with the median septum as in Spirifera granulifera. Nevertheless it would seem that the three structures are modifications of the same elements. But what is the element thus modified ? Prof. King suggested that the shoe-lifter process of Cleiothyris concentrka is a modified form of the ventral median plate; but the wide separation of its points of origin from the normal position of thisplate seems incompatible with such a conclusion ; while in Syringothyris and Spiriferse granulifera the median plate exists independently of the apparent homologue of the shoe-lifter. Mr. Billings, whose observations are generally marked by ex- treme sagacity, regards the shoe-lifter "as an abnormal form of the pseudo- deltidium that occurs in some Spirifers." This is the relationship pointed out above ; and there seem to exist good morphological reasons for regarding the fistuliferous arching plate of Syringothyris as a modified pseudo-deltidium. But to what does the latter structure appertain ? In Merista, Syringothyris and cer- tain Spiriferse its relation to the dental plates suggests that it may be an out- growth of those parts. The dental plates are amongst the most heteromorphous structures of the ventral valve. From a normal erect position, they become ap- proximated along the ventral margins in many Spiriferse and other genera, while in Pentamerus, Orthisina and Camarophoria this approximation results in com- plete union, and in Leptsena in the formation of the saucer-shaped process of the ventral valve. They also vary excessively in longitudinal development. In many Spiriferse, moreover, there is an evident indication of a longitudinal fold- ing of the dental plates, producing on one side or the other a longitudinal lami- nar process, which, under an extraordinary development, may coalesce with some neighboring part. While, therefore, the shoe-lifter process of Merista, and still more the fistuliferous diaphragm of Syringothyris, may be but modifications of the false inner deltidium of Spirifera granulifera, the three structures acci- dental among Palliobrancbs may be but mere outgrowths of the essential and typical parts known as dental plates. The geological range of the above generic type is, as far as known, only from the base of the yellow sandstones at Burlington, Iowa, to the Keokuk limestone. The species from the latter horizon cannot at present be characterized. There are reasons for believing that Spirifer extenuatus, Hall, from the yellow sand- stones at Burlington, will yet be found to possess the same peculiarities, if it is not a variety of one of the following species. Syeingothyris typa, n. sp. Shell large, thin, externally destitute of radiating ribs, or showing them but faintly. Ventral valve with a broad, undefined, rather shallow sinus ; beak extremely elevated ; slope thence nearly straight to all parts of the margin ; area very large, triangular, flat, forming an angle of about 30 with a line along the bottom of the sinus, and perforated by a rather broad tri- angular fissure. Dental plates diverging at an angle of 30, continued nearly to the apex of the beak, and extending anteriorly beyond the middle of the valve. Attachments of the myary system unknown. 1863.] 8 PROCEEDINGS OF THE ACADEMY OP The external characters of this shell resemble those of Spirif era simplex, Phil. (Pal. Foss. p. 71, pi. xxix. fig. 124, and pi. lx. fig. 124), but the hinge-line is more elongate. This species, so far as is certainly known, is restricted to the base of the Burlington limestone. Syringothyris Halli, n. sp Shell of medium size, transversely elongate, widest aloDg the hinge-line ; greatest depth of the two valves equalling or ex- ceeding the greatest length. Ventral valve with a deep, defined sinus; beak very elevated : surface sloping thence with but little convexity, to all parts of the margin, being sometimes even concave between the apex and the cardinal extremities ; area large, triangular, transversely striate, flat or slightly arched, with a more marked incurvation just beneath the beak ; perforated by a narrow, or moderately wide, triangular fissure, which is grooved along its lateral bor- ders as if for the reception of a deltidium ; dental plates rather short in a va- riety, very short diverging at an angle of G6 ; mesial septum a low ridge ex- tending two-fifths the length of the valve ; line of divaricator scars extending with a curve from inner end of dental plates to inner end of mesial septum. Dorsal valve moderately ventricose, with a convex surface, and abrupt well- defined mesial elevation, and a small beak which overhangs the base of the fissure in the area of the opposite valve, the area being scarcely perceptible in the dorsal valve. Surface ornamented by 12 to 16 rounded ribs on each side of the mesial fold and sinus, becoming obsolete toward the lateral angles. Mesial fold and sinus destitute of ribs. The whole surface is further marked by faint, delicate lines of growth. Length of hinge-line 1-32 (100) ; depth from beak of ventral valve to most prominent pointof dorsal which is nearly at right angles to the plane of the valves *70 (53) ; distauce from hinge-line to middle of anterior margin 54 (41) ; elevation of (ventral) area -48 (36) ; width of fissure at base 28 (21). Ranges through the yellow sandstones. In bed No. 1 is a variety with some- what convex area, very narrow fissure and very short dental plates. The species occurs also at Clarksville, Mo., where the beak of the ventral valve is bent somewhat to the left (this beak being uppermost) in the style of a Streptorhyn- chus producing a curvature of the mesial sinus and the fissure ; and is further peculiarly marked by several distinct lamellar wrinkles of growth. Named in honor of Prof. James Kail, the eminent Palaeontologist of Albany, N. Y. AVICULA, (Klein,) Bruguiere. Avicula Whitei, n. sp. Shell large, transverse, exceedingly oblique, with neariv terminal beaks. Hinge-line more than three times the greatest dorso- ventral dimension. Anterior ear pouched, not distinctly divided from the body of the shell. Left valve ventricose; umbonal ridge somewhat arcuate, or nearly straight, forming an angle of about 20, with the hinge-line ; slope thence to the ventral margin very rapid to the dorsal side rather gradual and symmetrical to the very hinge-line the posterior wing not being divided from The body of the shell. Ventral margin, in the middle rather straight and near- ly parallel with the dorsal ; posterior margin sigmoidal by a deep, or rather shallow sinus, isolating the posterior end of the cartilage plate from the body of the shell; posterior wing triangular, exceeding the shell. External surface marked by numerous fine, irregular stria? of growth. Right valve much less ventricose, marked on the body and anterior slope by numerous sharp, regular raised concentric strire which become very faint posteriorly. Cardinal line in each valve with a long, slender, bifid lateral tooth behind the beak. Length of dorsal side 2-13 (100) ; greatest dorso-ventral dimension -70 (33) : depth of left valve -22 (10). Avicula acanthoptera, Hall, (Geol. Rep. 4th Dist. N. Y., p. 263). Shell [Jan. NATURAL SCIENCES OF PHILADELPHIA. 'J rather large, very oblique, becoming distinctly arcuate upwards. Left valve very ventricose, with a tapering, incurved beak, closely approximated to its fellow ; body of valve regularly arched along the umbonal slope, from which line it describes a rapid convexity to the anterior margin, sloping more gradu- ally to the ventral margin and becoming gradually flattened toward the posterior ventral angle. The upper boundary of the body is an abrupt descent to the plane of the posterior wing, and sharply divides the two ; posterior wing sloping to the dorsal and posterior borders of the valve, produced above into a slender spine, nearly as long as the posterior end of the shell, with a deep sinuation below. Anterior ear short, saccate, less distinctly divided from the body of the valve. Hinge-line straight, with a long, posterior cartilage facet. Surface marked by irregular wrinkles of growth which become fine striae on the posterior wing, and sharp plications on the an- terior slope and auriculation. Right valve smoother and considerably less ventricose, with the posterior wing-surface divided from the body of the valve only by a slight groove. Length from beak to extremity of posterior wing -81 ; from beak to extremity of anterior wing -21 ; from middle of dorsal side to ventral side -70; greatest width of body of shell -48 ; same width in a larger specimen -93 ; depth of right valve of same specimen -30. An occasional specimen of this species, differing from the types of the above description only in the absence of arcuation of the body, presents a good agree- ment with Prof. Hall's figure and brief diagnosis, diverging only in the less forward direction of the beak, in the much larger anterior ear, and deeper byssal sinus beneath it. The prevailing forms greatly resemble Avicula lunu- lata, Phil. sp. (Geol. Yorks, ii. pi. vi. fig. 12). It is, however, less oblique, es- pecially in the earlier stages of its growth, and the beak is narrower and more depressed. It is also considerably broader on the aatero-ventral side, and has a larger posterior wing. AVICULOPECTEN, McCoy. Aviculopecten Caroli, n. sp. Shell of medium size, subcircular, ventri- cose. Hinge-line shorter than the shell; anterior ear of right valve shorter than anterior end of shell, rounded, slightly inflated, with a deep, sharply- rounded notch below; posterior ear acute, slightly longer than the anterior, with a broad, shallow notch below ; shell otherwise nearly equilateral. Beak central, inconspicuous ; greatest convexity of valve a little above the middle. External surface of the body of the valve marked by about 25 nearly equidis- tant, narrow, sharply-raised, radiating ribs, with two or three fine, raised striae in each of the interspaces ; a set of very fine, sharp, close, concentric raised lines cross the smaller ribs, but are intercepted by the primary ones. The latter, however, show a tendency, toward the pallia! margin of the valve, to de- velope nodes, which, on the anterior and posterior slopes, become distinct spines. The spines sometimes oceur in the spaces between the primary ribs. The wings are also marked by two sets of raised lines, but on the posterior wing the radiating set is most prominent, while on the anterior wing the concentric set is strongest. The left valve is exactly like the right, except that the notch below the anterior ear is shallower. Length from beak to ventral margin -66 (100) ; length of hinge-line -55 (83) ; convexity of right valve -20 (30) ; antero-posterior dimension -6$ (100). Num- ber of concentric lines in one-tenth of an inch, 16. The adult size of the species seems to be about one inch in length and breadth. Ranges from the base of the yellow sandstones into the base of the Barling- ton limestone. Aviculopecten occidektalis, n. sp. Shell small, appressed ; hinge-iine equal to greatest width ; anterior and posterior umbonal ridges at right angles, and straight to the middle of the shell extremities, between which the pallial 1863.] 10 PROCEEDINGS OF THE ACADEMY OF margin is regularly curved. Wings distinct, the anterior slightly inflated, rounded at the extremity, and separated from the body of the shell by a rather acute notch, from which a furrow extends to the beak; posterior win- flat- tened, acute, subtriangular, with a shallow sinus below. Body of shell smooth wings with radiating ribs, strongest on the anteiior wing and crossed by equally strong concentric lines ; posterior wing with fine concentric lines. In the oolitic limestone ("No. 3" of White.) Avicclopecten TENOicosTUS, n. sp. Shell small, equilateral ; pallial margin circularly rounded between anterior and posterior extremities, which lie mid- way between the beak and opposite side. Beak slightly prominent; body of shell bounded by a truncation from beak to each lateral margin ; anterior truncation slightly concave. Anterior wing of left valve moderately inflated. as long as anterior side of shell, distinctly rounded at extremity, joinins hinge-line by a rounded angle, and separated from body of shell by a broadly Y-shaped sinus, rounded at the bottom. Posterior wing only very imperfectly seen. Surface (of left valve) ornamented by fine, rigid, nearly equidistant ribs, 50 or 60 in number, separated by concave intervals ; similar but finer ribs or striae marking the anterior ear. Frequently from three to five equidistant cos- tale elevations appear, each of which bears two or three of the ribs. A few inequidistant concentric lines are seen. Right valve unknown. Length from beak to opposite side "47 ; antero-posterior dimension the same. It is a little singular that of seven specimens of this species all are left valves, showing only the anterior ear. The posterior is probably flat and thin. POSIDONOMYA, Brown. Posidonomya? ambigda, n. sp. Shell of medium size, rather ventricose, somewhat oblique. Hinge-line short, straight, not surpassed by the inconspic- uous beak, abruptly rounded at the extremities ; sides of shell subparallel, somewhat straight ; ventral margin circularly curved, gaping at the antero- ventral angle. Cast nearly smooth, but bearing the impression of a few small, ir- regular wrinkles around the margin. Greatest dimension (from beak to ventral margin) -G5 (100); antero-poste- rior dimension -58 (89) ; angle of umbonal slope with hinge-line 70. Three left valves and one right, of an anomalous fossil are here referred with great uncertainty. One of the specimens is larger and relatively longer from beak to venter than the one described, and seems to have been everted around nearly the entire pallial border, producing an extensively gaping shell. The right valve is a smaller specimen, with the beak near the anterior extremi- ty of the hinge-line, and presenting the anomaly of a forward instead of a back- ward obliquity in this respect resembling Streblqpteria, McCoy, but without the anterior wing. The three valves could scarcely belong to the same species of any genus, but it would be folly to attempt a further discrimination at present. DEXIOBIA, n. gen. Etymology, Jtgi6c, on the right side and 0ia., strength, in allusion to the greater ventricosity of the right valve. Shell thin, inequivalve, inequilateral ; beaks separated by an undefined area. Right valve very ventricose, with a very prominent umbo, and a produced, incurved beak, strongly inclined forward. Left valve much less inflated, with a less prpminent beak, scarcely elevated above the dorsal margin. Hinge-line more or less extended, straight, or slightly bent, edentulous (?) furnished with a thickened cartilage plate bearing a linear posterior groove. Pallial line and muscular markings unknown. In his Report on the Geology of Iowa, (p. 522, pi. vii. fig. 10, a, b, c,) Prof. Hall has described, under the name of Cardiomorpha ovala (not C. ovata, d'Orb. [Jan. NATURAL SCIENCES OP PHILADELPHIA. 11 = }fac(ra ovata, McCoy,) a common species from the yellow sandstones of Bur- lington. This species Messrs. Meek and Worthen supposed to be congeneric with their Cardiopsis radiaia, (Proc. Acad. Nat. Sci. Phil., June, 1861, p. 144). From the same beds, Mr. C. A. White has more recently described a similar species under the name of Cardiomorpha {Cardiopsis?) parvirostris, (Proc. Bos. Soc. Nat. Hist., Jan., 1862, p. 31), which has the small beak and Luciniform as- pect of several other species referred by authors to the same genus * It was some time since remarked, however, by Mr. White, that amongst all his speci- mens of these two species, the left valves of C. ovata and the right valves of C. parvirostris, were entirely wanting. It appears also that Prof. Hall's description was drawn from a right valve. The idea, however, that the two sets of valves might really belong to one species, would not probably have been entertained but for the discovery of a specimen with both valves in closely fitting juxtapo- sition. On one side the specimen is C. ovata, on the other C. parvirostris ! The beaks of the two valves are wanting, but the ventral margins apply to each other with exactitude, the number of radiating lines in a given distance being the same on the two sides. From the same exhaustless deposits of fossil remains, Mr. White's industry has brought to light some other forms which present similar characteristics. It is evident that these fossils cannot be referred to any known genus. It is doubtful whether they fall within the limits of any recognized family assem- blage. Judging from their analogies, they must have been asiphonal, integro- pallial Pleuroconchs, though little evidence of the possession of a byssus has been detected. From the inequivalve family Avieulidse (including Aucella, to which they are most related,) they are clearly excluded by the greater ventri- cosity of the right valve, and the absence of an anterior wing and byssal sinus. From the free inequivalve Osircidie their great gibbosity distinguishes them. From Dolabra, McCoy, they differ in the greater ventricosity of the right valve and less transverse shape. In view of the facts above recited, though some palaeontologists may not re- gard them as sufficiently conclusive, I have ventured to publish a diagnosis of the supposed new genus. Dexiobia Wuitei, Winchell, (= Cardiomorpha ovata, Hall. -(- C. parvirostris, White.) Shell subrotund, with a slight anterior obliquity caused by a mode- rate protrusion of the antero-ventral border, from which, in the right valve, a slight elevation extends to the beak ; anterior margin rather straight above. Hinge-line short, regularly curved ; beaks nearly central. Surface marked by fine radiating ribs becoming obsolete toward the umbo and numerous irreg- ular concentric wrinkles, which are generally mo6t conspicuous in the left valve. Height from beak to middle of ventral margin 1-26 (100) ; greatest antero- posterior dimension, nearly bisecting the first measure, 1-16 (92) ; convexity of right valve -45 (35). Height of another specimen 1-67. Height and convexity of a left valve 1-19 (100) and -26 (22). Dexiobia Halli, n. sp. Shell small, semi-elliptic, subequilateral. Hinge-line straight, extended ; in some specimens as long as the greatest width of the shell. Right valve extremely ventricose, flattened and subalate toward the hinge extremities ; left valve with a very small obtuse beak, and slender poste- rior cartilage plate bearing a longitudinal median furrow. Surface smooth. Height from beak of right valve to middle of ventral side -65 (100) ; length of hinge-line -76 (117) ; ventricosity of right valve -35 (54). MYTILUS, Linnseus.

The small shells thus identified have heretofore been regarded as the young of M. occidentalism White and Whitfield, a species with which I formerly identified the Michigan types of M. Whitfieldianus, a close comparison of speci- mens, however, shows M. occidentalis to be quite destitute of the fine diverging strife which belong to perfect specimens of the other species. M. occidentalis, moreover, is more flattened between the umbonal ridge and the hinge-line, and does not attain more than one-fifth the length of the other. It bears conside- rable resemblance to Modiola lingualis, Phil., (Geol. Yorks. p. 209, pi. v. fig. 21.) ORTHONOTA, Conrad. Okthonota phaselia, n. sp. Shell transversely quadrangular. Beaks in- conspicuous, nearly terminal, not raised above the slightly-curved hinge-line. Ventral margin subparallel with dorsal, with a shallow sinuation in the middle. Posterior end truncately curved, a little the most extended toward the dorsal side; anterior end slightly produced below, with a deep lunette above. Shell inflated from the anterior end to near the posterior. Greatest thickness a little in front of the middle. Anterior muscular pit shallow, ovately pyriform. Surface with a few remote concentric lines near the border. Length -35 (100) ; height -20 (57) ; thickness of both valves -13 (37). EDMONDIA, de Koninck. Edmondia nitida, n. sp. Shell small, equivalve, suborbicular, ventricose, slightly oblique, with a subcentral beak. Hinge-line slightly extended poste- riorly, obtusely rounded at the extremities ; anterior and posterior sides sub- parallel ; ventral border circularly rounded, but a little produced in the line of the umbonal ridge. Beak elevated above the hinge, obtuse, slightly incurved ; umbonal ridge making an angle of 66 with the hinge-line; behind this ridge the elope is abrupt to the posterior border; middle portion of the shell very slightly flattened from the beak along the region anterior to the umbonal ridge. Surface handsomely marked by rigid, regular concentric raised striae, with a few remote, irregularly-distributed concentric furrows. The striation is pre- served in all its sharpness to the very hinge-border. Length -59 (100) ; height -59 (100) ; thickness of both valves -30 (51). Closely resembles E. unioniformis, de Kon., (Anim. Foss., pi. i. fig. 4,) but the latter is less finely and elegantly striated, and shows no flattening along the region between the beaks and the ventral border. It is much less flattened and less angular than E. binumbonata, Win., from Michigan. Edmondia nuptialis, n. sp. Shell of moderate size, transversely-suboval ; ia adult specimens considerably inflated in the vicinity of the pallial border. Beaks subcentral, small, incurred, somewhat elevated above the moderately extended, slightly arcuate hinge-line. Ventral margin gently curved or nearly straight in the middle; more rapidly curved toward the rounded, subequal ex- tremities. Hinge structure obscure, but apparently consisting of one or more lateral teeth on each side of the beak. Surface unequally and interruptedly furrowed. Greatest thickness through the middle of the shell. Length -79 (100) ; height -62 (78) ; thickness of both valves -50 (63). This species is relatively larger than E. nitida, and is destitute of the obtuse angulations descending along the anterior and posterior umbonal slopes of the latter. An associated, if not identical, species is less ventricose, with less central beaks, and can scarcely be distinguished from Lucina? retusa, Hall. Edmondia strigillata, n. sp. Shell rather small, rather gibbous, trans- versely oval ; beaks subcentral, elevated, obtuse, somewhat strongly turned forward. Ventral margin gently arcuate in the middle, more rapidly curved toward the neatly-rounded extremities, of which the posterior is broadest. Hinge-line curved, furnished with a pair of rather thick lateral teeth ; cardinal ieetb, apparently none. Surface marked by fine radiating lines, and toward the margin by a few irregular concentric wrinkles. [Jan .

Edmondia ^eqdimarginalis, Win., (=Cardinia xquimarginalis, Win., Proc. Acad. Nat. Sci. Phil., Sept , 18G2, p. 413.) The identification with the Michigan species is quite conclusive, but the better state of preservation of this fossil necessitates a correction of the generic reference. Edmondia (?) bicarinata, n. sp. Shell rather small, transverse, oblong, a little the widest at the posterior extremity of the straight, lengthened hinge- line ; dorsal margin erect, not inflected ; ventral margin subparallel with the dorsal, having a distinct shallow sinus near the middle, which leaves a dimin- ishing furrow extending to the beaks ; angularly rounded to the extremities, of which the posterior is truncate by a slightly curved line at right angles with the hinge-line, and another above this forming an ang'e of about 135 with the hinge-line. Beaks one-fifth the length of the shell from the anterior end, somewhat flattened, and incurved over a deep, distinct lunette. Greatest con- vexity one-third the distance from the dorsal to the ventral sides. A strong angular ridge extends from the beaks to the posterior ventral angle, and another, less conspicuous, to the angle connecting the two posterior truncated margins. Surface marked by fine incremental lines, parallel to the basal and posterior borders. Length -59 (100) ; height -27 (41) ; thickness of both valves -12 (20). Edmondia (?) elliptica, n. sp. Shell rather large, appressed, transverse, with an elongate-elliptical outline. Beaks flat, inconspicuous, situated one- fifth the shell-length from the anterior end. Hinge margin elongate, slightly curved, abruptly elevated ; a flattened area extending from the beaks back- ward to the posterior hinge angle. Extremities neatly rounded. Surface marked by numerous distinct unequal lines running parallel with the pallial margin. Length 1-36 (100) ; height -65 (48). SANGUINOLITES, McCoy. Sanguinolites amygdalinus, n. sp. Shell of medium size, equivalve ; length equal to two and a half time3 the height ; beak about one-fourth the length from the anterior end, scarcely elevated above the hinge, somewhat depressed, incurved ; dorsal margins slightly concave, posteriorly inflected inwards, form- ing a deep escutcheon ; ventral margin gradually curved along the middle, more rapidly so toward the extremities ; posterior extremity describing nearly a semicircle, and joining the dorsal line by a very easy angle ; anterior extrem- ity abruptly rounded to the deep, broad lunette, which reaches from the beak to the middle of the shell. Greatest protuberance one-third the distance from the beak to the venter, rather tumid ; an obtuse angulation extending from the beak to the postero-basal angle; a strong internal ridge running near to, and parallel with, the hinge-line. Surface marked by strong concentric wrinkles, which nearly disappear in the dorsoumbonal region. A shallow sinus in front of the mid-ventral margin, which can be traced upward toward the beak. Length -97 (100) ; height -44 (45) ; distance of beak from anterior end -25 (26) ; from posterior -72 (74) ; thickness of both valves -36 (37). Somewhat resembles Allorisma Hannibalensis, Shum., but differs in the ab- sence of the "broad concentric ribs" of that species. It less resembles the Burlington fossil, usually referred to the same species. Sanguinolites cylindricus, n. sp. Shell small, equivalve ; length equal to two and a half times its height; beak about one-seventh the length from the anterior end, elevated above the hinge-line, flattened and enrolled; greatest height along the perpendicular from beak to base; dorsal margin extended, 1862.] 14 PROCEEDINGS OF THE ACADEMY OP slightly concave upwards and inwards, sharply inflected inwards, forming a long, deep posterior escutcheon or cartilage base; ventral margin nearly straight, curving rapidly from a point opposite the beaks to the anterior ex- tremity, which is abruptly rounded into the deep heart-shaped lunette ; poste- rior extremity truncated by a line extending from the basal to the dorsal mar- gin, and making with the latter an angle of 120. Valves very ventricose, the greatest thickness being behind the central point on the sharp, prominent umbonal plication, which extends from the beak to the postero-basal angle the area between this plication and the anterior region being curved subcylin- drically from a dorsal to a ventral direction, and the area between the plication and the hinge-liue being a triangular, twisted, somewhat concave surface, faintly marked by lines diverging from the beak to the posterior boundary. Entire surface covered with fine irregular striaj parallel with the basal and anal margins. Length -63 (100) ; height -29 (46) ; thickness of both valves -24 (38) ; height of posterior end -20 (32) ; length of anterior end -09 (14); of posterior end 54 (86). A peculiarity of this fossil is its cylindrical ventricosity and the posterior position of its greatest distension. (Compare Owen, Geol. Rep. Wis., Min., &c, Tab. III. a, fig. 18.) Sanguinolites Iowensis, n. sp. Shell of medium size, equivalve, transverse ; height equal to nearly one-half the length ; beaks elevated above the dorsum ; subappressed, incurved and turned forward over a deep cordate lunette ; dor- sal line straight, reaching to near the posterior extremity of the shell ; dorsal margin sharply inflected to form a long cartilage base ; ventral border gently curved, posteriorly receding toward the dorsum, and forming at the extremity an angle of 80 with the short, truncate, nearly rectilinear biod margin ; ante- rior extremity most projecting in the middle, from this point curving regularly to the ventral border and abruptly into the anterior lunette. Valves ventri- cose, most inflated in the middle ; a sharp carina running sigmoidally from the beak to the postero-basal angle; another, still sharper, bounding the (poste- rior) escutcheon ; the twisted triangular space between these being marked, on the cast, by three faint depressed lines, radiating also from the beak. External surface marked by irregular lines of growth, strongest on the anterior portion and faintest on the dorso-umbonal surface. In some specimens apparently not separable from this species, a shallow groove runs from the ventral margin nearly opposite the beak, over the umbo*. Length 103 (100); height -52 (50); thickness of both valves -38 (37); length of anterior end -21 (20) ; of posterior end -82 (80). The forms last mentioned above attain a size fully once and a half as large. The typical specimens of this species are quite distinct, but the larger ones approximate to S. amygdalinus in outline and characters of the dorsal region ; but they differ in being larger, more ventricose, and in having a sharp umbonal angle and acute posterior extremity. Sanguinolites sdlciferds, n. sp. Shell very small, transversely obloDg, ' with nearly terminal beaks. Ventral margin broadlj and rather deeply sinuate in the middle; anterior margin abruptlv rounded below, terminating above in a deep lunette ; posterior margin somewhat produced below, suddenly rounded at the basal angle, and very obliquely truncate from thence to the end of the second third of the dorsal side, from which point the straight hinge-line ex- tends to the beak. Cardinal margins inflected to form a narrow, elongate escutcheon. Umbo full ; umbonal ridge arcuate, with the convexity upwards, and terminating at the posterior basal angle ; space above this somewhat con- cave, longitudinally marked by seven or eight strong imbricating concentric ridges.

Valves somewhat appressed ; greatest distension one-fourth the distance from the beak to the venter. Surface of cast marked by faint lines of growth.

Some specimens associated here are relatively shorter posteriorly, but not otherwise distinguishable. McCoy's generic names and distinctions, SanyuinolUcs and Leplodomus, seem preferable to King's Allorisma, inasmuch as the latter name, besides being subsequent in time, was originally defined under an erroneous idea, and was finally left to embrace shells regarded as sinupallial, a character which does not seem to belong to the so-called Allorismas of the Palasozoic period. San- guinolites lowensis, and probably some of the others just described, are allied in form to Cypricardia ; but I agree with Pictet and others in believing that, while we have no evidence of the existence of the teeth of Cypricardia in any of the Palaeozoic species generally referred to that genus, it is more natural to throw them into another association. Moreover, the sharply-inflected dorsal margin and broad, elongate posterior escutcheon, present in all the species of Ccelonotidie, would seem to indicate real affinities, and thus withdraw the Allorisma type entirely from the association in which it has been placed.

The genus Viviparus, or the Viviparidasofthis synopsis, are the only mollusks which appear to undoubtedly belong together ; of the^ other genera that have been referred by the Adams, Gray and Chenu to the family, Tanalia and Palu- domus are apparently rather related to the Melaniidae, and nearly agree in form of the shell, with Leptoxis of Raf. or Ancylotus of Say, while the structure of the animal, as far as described, is essentially similar to that of the true Melani- ans* and they agree with Viviparus only in possessing an operculum whose elements are concentric, but which is in other respects quite different.

Branchiae in a single row, in the form of trans- verse folds, somewhat dilated at the middle. Generative organs on the right side; verge external, behind the tentacle, bifid and with unequal branches ; female orifice under the margin of the mantle, on the same side. The following types belong to this family : Amnicola Gld. and Hald. ; Chilocyclus Gill ; Somatogyrus Gill. Bythinia Leach. The subgenus Bythinella of Moquin-Tandon corresponds to the genus Amnicola of Gould and Haldeman, and consequently should be so treated, al- though its first species apparently belong to the subgenus Pomatiopsis of Tryon ;f the materials now in my possession, or in the Smithsonian Collection, do not enable me to form a satisfactory opinion concerning that group : at present, I am disposed to doubt its distinction from Amnicola. In the present paper it is proposed to classify only the Viviparidse. The family of Amnicolidae has been recently proposed by Mr. Tryon for the genus Amnicola, but that gentleman has given no diagnosis. It is more nearly allied to the Melaniidae than to the Viviparidas, and the genus Amnicola has been referred to that family by Mr. Lea. The material of the Smithsonian Institution, &c, being now in the hands of Mr. Binney, I am unable to arrive at a satisfactory conclusion regarding the limits of our species, and, while expressing my opinions on the classification of our species by reference to those admitted by Binney, except in a single case, I feel somewhat disposed to dissent from him in several instances. As such a differ- ence of opinion would not necessitate any modification of the distribution among groups here proposed, I do not feel at liberty to dissent from him at the present time. J I have seen specimens of almost all the species enumerated. * The American Melaniidae, so far as I know, have not a fringed mantle and consequent- ly belong to a different group. t The subgenus, as defined by Tryon, is alluded to , the type of that group (A. lapi- daria) may, however, be quite different, and a representative of the family Aciculida;. fThe identification of Paludina Elliotti Lea, with P. cyclostomatiformis, is most doubt- ful.

Family VIVIPARID^E (Gray,) Gill. Animal elongated, semicylindrical, with the spiral visceral sack contained in a turbinate shell, into which the rest of the body is also perfectly con- tractile. Mantle encircling the neck with a very thin fold, simple in front. Foot, distinct from the neck, moderate, extending beyond the head, arched in front, and obtusely extended towards its angles, rounded behind ; adapted only for crawling. Head moderate, with the rostrum produced, entire or nearly so in front above. Jaws two, lateral. Tentacles two, contractile, with the eyes on short tubercles on the outer sides of their bases. Lingual ribbon strong, slender and elongate. Teeth in seven longitudinal rows, (3 | 1 | 3) laminar, with re- curved apices ; lateral convergent. Branchiae internal, and along an oblique line down the left side of the branchial cavity, in three regular rows, composed of flattened, slightly subulate filaments, scarcely dilated towards the posterior third (in types). Respiratory orifice under the collar, at the upper and hinder part of the neck. Generative organs, unisexual, on the right side ; verge at the end of the tentacle, in which the de- ferent canal is contained. Female orifice on the same side, under the margin of the mantle. Shell turbinate, conoid, covered with a thin, transparent, or rather thick, greenish, or olive periostraca; with the septa persistent; the aperture subovate, and with a continuous peritreme. Operculum annular. The shells of the groups and genera of the family represented by American species are distinguished as follows : a. Shell subconic ; lips continuous on a uniform plane Vivipari. 1. Shell with revolving nodulous carinte. Aperture slightly effuse at base Tulotoma. 2. Shell with the whorls smooth. Aperture broadly rounded at base Viviparus. /?. Shell turreted. Outer lip subangulated, sinuous or incurved at base Lioplaces. 1. Operculum with concentric elements Melantho. 2. Operculum with a spiral nucleus Lioplax. The groups of Vivipari and Lioplaces, among which the American Viviparidas may be thus distributed, are decidedly distinguished by differences of den- tition, which are coincident with the well marked conchological characters. The dentition of Viviparus, Melantho and Lioplax has been examined ; although that of Tulotoma is still unknown, it is not probable that it will be found to ex- hibit any important difference when compared with the dentition of Viviparus. Group VIVIPARI. The rachidian teeth are broad, rather wider and more or less angulated to- wards the base ; recurved at their superior margins, which are also denticulated Lioplax ; and in this opinion I am supported by Mr. Tryon. Although autoptically unac- quainted with P. Elliotti, I judge from the figure that the form of the aperture and the carination of the whorls are alike in both ; the operculum of P. Elliotti is unknown ; a knowledge of its structure will decide the doubts concerning the affinity of the species. I am not acquainted with the reasons influencing Mr. Binney in his union of the two species. The arguments in favor of a union of so dissimilar 6pecies might not be unde- sirable, for an examination of the figures alone would scarcely * convince one of the iden- tity" of the two, but rather produce a contrary belief.

Shell imperforate, conic, rather thin, becoming more elongated and conic in its progress to maturity, with the whorls little convex ; whorls in adult with two nodulous revolving carinse, the lower of which is covered by, but produces a ridge beneath the suture of the succeeding whorl. Aperture obliquely semi- cordate, slightly effuse at base; lips continuous in a uniform plane ; outer lip thin ; columellar lip straight or little concave and obtusely connected behind with the outer. Operculum corneous, with its elements entirely concentric. Tulotoma is represented by only one species inhabiting the streams of Georgia and Alabama. It is readily distinguished from the typical Vivipari, to which it appears to be most nearly allied, by the form of the aperture, the nodulous carinae of the adult shell, and also by the form of the adult shell itself. The adult has been described as " heavy," but it does not appear to be really much more so than that of Viviparus. Tulotoma magnificum Tryon ex Conrad. = Vivipara magnifica B. ex Conrad.

Lips continuous on a uniform plane; outer lip thin, columellar lip concave, closely appressed behind to the body whorl and forming nearly a right angle with the outer. Operculum corneous, with its elements wholly concentric. Viviparus, as here restricted, is a very natural and widely-distributed group.

The third section of Viviparus, or another closely related to it, perhaps in- cludes V. bengalensis (Ad.) ex Lam., V. borroughianus Gill ex Lea, V. bilineatus Gill, and other Indian species ; the suspicions that might be entertained as to the strict affinity of species so widely separated geographically, can only be relieved by an examination of the mollusks themselves ; the shells are very similar. The genus Viviparus is represented by a number of species in the lignite beds of Fort Union which have been referred by Messrs. Meek and Hayden to the Eocene epoch. My friends, Messrs. Meek and Hayden, have adopted the same conclusions as myself regarding the distinction of Viviparus and Melantho, and have now referred, with myself, six of the species formerly described by them, to Viviparus, accepting that name, and two others to Melantho. Five of those species are distributable among the three groups above indicated, while the sixth is the representative of a distinct one. The following list shows their affinities : \ I- Viviparus Leaii M. and H. retusus M. and H. " Conradi M. and H. I II. \ HI. " trochiformis M. and H. " Leidyi M. and H. I IV.

These species will be illustrated and fully described in the forthcoming work of Meek and Hayden on the Fossils of the Upper Missouri country. In the beds at Fort Washington on the banks of the Potomac River, which probably belong to the Post Pliocence epoch, a species of Viviparus is found in great numbers, which appears to be referrible to the V. subpurpureus ; the latter is now only known to exist in Florida and the Western States.

MELANTHO Bowdich. Shell imperforate or rimate, turreted, thick and of very compact structure, never provided with colored bands, with the whorls more or less compressed longitudinally, smooth or rarely carinated. Aperture obliquely semi-cordi- form, rather narrow, broadly rounded and sinuous or retreating backwards at the base, the outer lip trenchant, and produced near the base ; columellar lip nearly straight, closely appressed to the body whorl and forming nearly a right angle with the outer. Operculum corneous, with its elements wholly concentric. Melantho is a type peculiar to America, I believe. It is readily recognizable by the peculiar physiognomy of the shell, produced by the compression of the whorls in a longitudinal direction, so that the sides of each are nearly parallel, and a turreted form is thus obtained. It may be therefore likened, as to form, [Feb. NATURAL SCIENCES OF PHILADELPHIA. 39 to the genus Latrunculus of Gray, or Eburna of others.* The shell structure appears to be more compact than in the typical Vivipari, and the species gen- erally are more ponderous. The angulation of the outer lip and the sinus at the base are characteristic, and contrast strongly with the uniform plane of thp aperture of Viviparus. The figure of a <; deformed" V. decisa (36) published by Binney, gives an ex- aggerated idea of this peculiarity of form. The soft parts of Melantho appear to also differ from those of Viviparus, the rostrum being smaller and less protractile, and the auricles behind the tenta- cles are likewise much smaller. The earliest known American species of Melantho were contemporaneous with the Vivipari, three species having been discovered by Dr. Hayden in the lignite beds of Fort Union and described by Meek and Hayden as Vivipara mul- tilineala {=V. nebrascensis M. and H.), V. vetusta and Melania orLymnxa multi- striata.

I am happy to find that the validity of the groups of Viviparida% which have been above denned, is confirmed by the researches of Dr. Troschel, who has examined the dentition of several species of true Viviparus, besides that of the Pahidina subcarinata of Say, for which he has proposed the name Lioplax. The latter name is now substituted for Haldemania of Tryon, and is modified to form the name of a group containing that genus and Melantho. Additional Remarks on the North America iEGIOTHI. BY ELLIOTT COUES, A. M., M. D. Since the publication in the Proceedings of the Academy for November, 1861, of rny Monograph of the genus, the Smithsonian has been constantly in the receipt of additional specimens from all parts of North America. These were mostly the A. linarius ; but collections from the North have usually contained a number of well -characterized examples of A. exilipes. Nothing, however, of special importance has been elucidated, until the reception of a series collected in winter in the vicinity of Quebec. These specimens, as they throw much light on the variations of the typical species of the genus, A. linarius, will merit a brief notice. If the deductions I have drawn from these specimens are warrantable, we have in North America the forms long recognized in Europe as A. HolbSlli and A. rufescens ; and these are both rather races than distinct species. Selecting from the series two or three skins which differ most markedly from the usual style of linarius, and comparing them with a typical specimen of the latter from Philadelphia, I find the following differences : The bird is very decidedly larger. The difference in total length is nearly one inch, as near as I can judge from the dried skins. The wings and tail are each about a fourth of an inch longer. The tarsus and middle toe with its claw are together about two-tenths of an inch longer.* The bill and feet are decidedly larger and stouter, though perhaps not disproportionately so. The former is somewhat elongated ; its lateral outlines straight instead of a little concave ; its culmen slightly curved. The bill is of a bright chrome-yellow, except just along the culmen and at the extreme tip. The gular spot seems rather large. In other respects, the two birds are quite identical, for, with these differences in size, there is an exactly proportionate increase in the bill, feet, wings and tail ; and the colors of the two do not differ appreciably, ex- cept in the bill, and perhaps the larger gular spot. The specimens give the idea, in fact, of overgrown individuals of the common linarius. But now, on examining in detail the rest of the series, I find that, from the one extreme, the characters of which have just been given, there is a com- plete and gradual transition, a diminution in size, down to specimens which cannot possibly be distinguished from typical linarius. There is no break in the series ; no dividing point where we can stop calling the specimens " linarius" to give them another name ; in spite of the discrepancy which is so evident between the two extremes. The point of interest which attaches to these specimens, is the bearing they may have on the mooted question of the claims of sEgiothus Holbolli to full specific rank. As was the case at the time of the preparation of my Mono- graph, I have never examined a specimen which professed, upon good Euro- pean authority, to be that species. Careful examination, however, of the *The tarsus, middle toe and claw together, of the specimen sunder consideration, measure absolutely 1*20 inches ; the same parts in linarius are about one inch : in exilipes -80 of au inch. [Feb. NATURAL SCIENCES OP PHILADELPHIA. 41 figures and diagnoses of the various authors who have treated of this bird has shown that there are assigned to sEgiothus Holbolli, as dis- tinctive characters, exactly those differences from the linarius which exist in the specimens under consideration, viz. : larger size, larger, more elongated and bright yellow bill, and larger gular spot. I think there can be no reason- able doubt that these specimens represent in North America the form long recognized in Europe under the name of JEgiothus Holbolli. If this be the case, next comes the question, what rank are we to accord to this form. Is it to be looked upon as an accidental variation from the type, as a well marked variety, or as a distinct species ? Brehm was the first to proclaim it as distinct, and give it a name. Temminck, Sthlegel, Bonaparte, and other authors, who are rather more orthodox in their ideas of a species than is Brehm, have always inclined, more or less decidedly, to the opinion that it is rather a race or subspecies of A. linarius. The fact of there being a complete gradation towards the linarius, has not escaped attention, and has been a powerful argument against according to it full specific rank. For my own part, though unable to demonstrate the point incontrovertibly, I am in- clined to reiterate still more strongly the doubts expressed in my Monograph, as to the propriety of separating it from the linarius. Pursuing this question of the variations which A. linarius presents, we find another species, A. rufescens, which has never been able to fully vindicate its claims to specific distinction. First introduced by Vieillot, its existence was strenuously denied by Temminck, doubtfully regarded by Bonaparte and Schlegel, and admitted by Cabani-> and others. I have always entertained strong doubts as to its validity. The characters assigned are slight enough ; and that they exhibit a gradation towards A. linarius, is admitted even by those who contend for its separation from that species. In examining two hundred or more specimens, I find many individuals, fully as small, in fact, and with as much of a reddish tinge, as specimens from Europe labelled li ru- fescens " by good authority. The existence, then, in North America of these two races, or species, which- ever they may be, the one larger and the other smaller than the typical lina- rius, m ay be considered as exceedingly probable, if the fact be not actually demonstrable. As a sort of negative argument, I may remark, that one might naturally look for their occurrence in this country, as tbe typical lina- rius from Europe is absolutely identical with our own. JEgiothus rufescens and A. Holbolli, compared with A. exilipes, afford a good illustration of the limits between which a species may vary from its normal type ; while another species, looking at first glance more like this type than do either of its extremes, is permanently distinct. I have no reason to change any of the views expressed with regard to three new species I have introduced. Additional specimens confirm the position as- sumed, especially regarding A. exilipes. I may here, however, correct a typographical error, which gives the date of the first introduction of A. fusees- census "Aug., 1860," instead of "Aug., IStil." March 3d. Mr. Jos. Jeanes in the Chair.

Grant, M. D. Dr. Leidy directed attention to some portions of the aorta of a horse, con- taining parasitic worms, presented this evening by Dr. R. Jennings, veterinary surgeon. The worms belong to the species Sclerostomum armatum. A letter from the donor, giving an account of the case, observes : "The horse appeared generally in good condition, and was a yearling colt. It was taken with symptoms of prostration, and slightly hurried respiration, and died four hours after the attack was noticed. Patches of inflammation were observed in various parts of the intestines, aud several of the mesenteric .glands were of a dark bloody appearance, and contained clusters of small worms. Parasites of the same character were noticed in the liver, and on the exterior of the kidneys. ' A clot of blood, the size of a goose egg, was found between the coats of the left iliac vein, and contained a large number of the worms. They appeared to have perforated the internal coat of the vein, and thus caused the extravasation of blood. The worms were also observed in small clusters contained in the coats of the thoracic aorta." Dr. Leidy also exhibited a specimen of sheep wool, striped alternately black and white, which was presented this evening by Mr. Joseph P. Hazard. In a note the donor observes, that his brother, Mr. Rowland G. Hazard, of Peace Dale, R.

Trachycephalus, Tsch. In the most recent enumeration of the species of this genus (by Dr. Gunther, 1858,) four are recognized: one, T. geographicus, from Brazil, and three from the Antilles. I am enabled to add four to the latter, which have been sent from those regions by 'Messrs. Wright and Weinland, and Professors Poey and Adams, all well known as most efficient laborers in advancing our knowledge of zoology in that field. It does not appear to have been stated that the males of certain species of this genus, T. inarmoratus, insulsus, o v a t u s, possess, during the breeding season, a corneous sheath upon the tuberiferous metacarpus of the inner anterior digit, as occurs in Discoglossus and Scaphiopus. Specimens of males in which the generative organs are not enlarged, are destitute of thi3 pellicle ; it is, however, readily lost after saturation in fluid. Its object here, as elsewhere, is to assist the powers of prehension of the male. The following table contrasts the peculiarities of the West Indian species : A.

The palmation of the ringers in this species varies between bare existence and an extent equal to one-fourth the length of the digits. The series of vomerine teeth are either arched or straight. As the peculiarities of the Hyp- siboas dominicensis of Tschudi, as defined by Dumeril and Bibron, are exhibited within this range, I am induced to believe that it is but a nominal species. The dominicensis of Gunther, possessing a more extensive palmation of the anterior digits, is so far similar to the o vat us from the same island. I agree with that author in assigning the same name to the Jamaican animal, which is, according to him, the frog called Hyla brunnea by Mr. Gosse. The specimens labelled erroneously in Mus. Paris as having been brought from Cape North, in Norway, under the name Hyla septentrionalis, belong to the present species according to the " Erpetologie Generale."

It is altogether probable that this is the species described by Mr. Gosse, in his work previously mentioned, under the name adopted. His description, re- lating principally to coloration, is not conclusive towards any identification. Its affinities are altogether with the lichenatus, both being peculiar in the elevation of the posterior margin of the casque into a transverse crest. It differs in the greater elevation of this crest, the more elongate proportions of the cranium, the angulation of the canthus rostralis and less prominence of eyes, besides minor points. Hyla Laur.

This species is identical with that described in these "Proceedings," 1862, p. 353, as Hypsiboas raniceps. The name of the distinguished Danish zoolo- gi=t must be retained, as the memoir in which it appeared was issued some months prior to our own. The former has just come into our hands. Hylodes Fitz. Hylodes planirostris Cope, Pr. A. N. S. Philada., 1862, p. 153. This species, hitherto known as a native of the Bahama Islands, has been sent to the Mus. Smithsonian (No. 6310) from Southern Florida by Dr. Cooper. It is the only species of the genus found in the United States, though Holbrook and Agassiz have described frogs under this name from our country. These belong to the genera Acris, Hyla and Pseudacris. Other reptiles common to the Bahamas and Florida are Anolis principalis and Sphaerodactylus n o t a t u s. The following species of Hylodes form a little group which I have called Craugastor, 'Proc. A. N. S., 1862, p. 153. They can be distinguished as follows : H. p u 1 c h r i g u 1 u s, 1. c, 1862, 357. Tympanum one-fourth extent of orbit ; the latter equal distance from its anterior border to end of muzzle. Carpus reaching anterior border of orbit. Muzzle truncate. Tongue emarginate. Loreal region concave. End of tibia reaching the end of the muzzle. H. g r is e u s. Hylayrisea, Hallow., Pr. A. N. S. Phila., I860, p. 485. Tympanum obliquely elliptic, one-third the extent of the orbit; diameter of the latter less than the length of the rather elongate and rounded muzzle. Carpus and end of tibia reaching the end of the muzzle. Loreal region con- cave ; canthus rostralis strong. Tongue emarginate; external metatarsal tubercle not developed. H. h a 1 1 o w e 1 1 i Cope, 1. c, 1862, 153. Tympanum horizontally elliptic, equal one-third extent of orbit; latter equal in diameter to length of muzzle, which is much rounded; loreal region nearly plane ; canthus rostralis weak. Carpus reaches end of muzzle, the tarsus only the orbit. Two well developed metatarsal tubercles. Tongue entire ; mandi- bulum rounded. Herr Schmidt has not given the minuter peculiarities of his H. (Craug.) fit z- i n g e r i i so as to enable us to distinguish it from the above. It is most like the pulchrigulus. Phyllobates Bibr. Phyllobates latinasus Cope, sp. nov.

Expedition under Lieut. Michler. Hylaplesia Boie. Hylaplesia truneata. Phyllobates truncatus Cope, Pr. A. N. S. Philada., 1860, p. 372. A certain serrulation of the alveolar ridge of the maxillary bone, in this and the following species, greatly resembles dentition, and has caused their erro- neous reference to Phyllobates, instead of Hylaplesia. This animal is most like the H. o b s c ur u s e Bum., Bibr., but has much shorter posterior extremities. In both the anterior extremities equal the head and body ; in the former they are more than half the length of the posterior, in the latter, considerably less than half. In the t r u n c a t u s the first and second fingers are equal ; their expansions are one-fourth the size of the tympinum. The neural spines are very much dilated and thickened, especially that of the axis. There is a transverse bony ridge on the occiput. Hylaplesia a u r a t a. Phyllobates auraius Girard, U. S. Astronomical Expedition, ii. p. 209. In this species the muzzle is rounded, and the first finger shorter than the second, as in the H. t i n c tor i a. It has no occipital ridge, and the neural spines are only slightly thickened. Dilatations of posterior extremities one- fourth extent of tympanum ; of anterior, one-half the same. The ground color is black or brown. Crown and muzzle surrounded by a golden band ; two postscapular transverse annuli on each side, in contact on the median line ; a yellow annulus on each inguinal region; smaller rings on humerus and tibia. On pale specimens these markings are represented by refulgent bands which are readily destroyed or passed over ; hence the imperfections of Girard's de- scription. BUFONID.E. Rhaebo haematiticus Cope, Pr. A. N. S., 1862, p. 357. The genus Rhsebo is to be distinguished from Bufo by the presence of the manubrium sterni, in addition to the characters given, 1. c, p. 358. I have had opportunity of observing it in the present species and the R. leschenaultii. This character has been denied to all Bufones in Stannius' "Handbuch der Zootomie." I find it also in "Bufo simus Schm." 1. c, p. 357, which can hardly be placed in Rhasbo. I cannot assign it to a new genus until the value of its peculiarities is better known. The genus of Bufonida? for which I have adopted, in the above quoted article, Fitzinger's name Chilophryne, is not alone characterized by the presence of a parietal branch or continuation of the supraorbital ridge, as there indicated ; but rather by the straightness of the latter, its not describing the usual arc of the orbit, and its angle with the postorbital ridge, when the latter is present. The parietal ridge sometimes exists in a rudimentary or fully developed con- dition in Phryno'idis. P. sternosignatus e Gthr., illustrates the first case, and P. d' o r b i g n y i the last. As the latter species is the type of Chilophryne 1863.] 50 PROCEEDINGS OF THE ACADEMY OP Fitz., thi3 name must become a synonyme of Phrynoi'dis, and the genu3 to which I fiist applied it be called Incilius. The species which truly belong to it are I. lentiginosus, cognatus, woodhousei, americanus, n e- bulifer, veraguensis, coniferus, d i a lo p h u s, and probably bi- porcatus. The species d'orbignyi, c e 1 eb e nsi s and occellata formerly referred to it, must be placed in Phrynoi'dis Fttz. Bufo diptychus Cope, 1. c, 353, is the species described by Dr. Girard, a3 B. poeppigii Tsch., in Herpetology of U. S. Exploring Expedition. It is distinct from Tschudi's toad. CERATOPHRYDID.E. This family has been recognised in an indefinite way by Dr. Tsehudi,* who gives as its distinguishing features " kopf sehr gross, eckig, schief nach vorn verliingprt ; Hautverlangerungen am obern Augenliede." He includes in it the genera Ceratophrys, Phrynocerus, Megalophrys and Asterophrys. The unnatu- ral nature of this union has been demonstrated by Dr. Giinther, who places Asterophrys and Megalophrys in separate families, and assigns Ceratophrys with Phrynocerus to the Ranidae. The Ranidae of Giinther is, however, a hetero- geneous group ; and I would separate under Tschudi's name those genera of toad-like animals in which the manubrium sterni is wanting. These are Cera- tophrys, Phrynocerus and Pyxicephalus ;f probably Calyptocephalus will enter the same series ; but these I have not seen. Tschudi's inapplicable characters may be replaced by the following. Form slout, bufonine ; .head broad, elevated, Os maxillare toothed. Extremities short ; digits without terminal discs ; the posterior more or less webbed. Ear perfectly developed. Diapophysis of sacral vertebra cylin- drical. Manubrium sterni ivanting. Faratoids present or absent. I am not now acquainted with other peculiarities, though they doubtless exist. The S y stem of Opisthogloss Anura proposed by Giinther, like the system of Ophidia of the Erpetologie Generale, is a valuable index of the subject, but not an exposition of the scheme of nature. I have already J ventured the opinion that a primary division into forms with, and forms without dilatations upon the extremities of the digits cannot be maintained : this character must be sub- ordinated, as that of the presence or absence of teeth on the maxillary bones as employed by Dumeril and Bibron, has been by Giinther himself. He at- taches greater value to the former because it "is connected with a strongly- marked distinction in the mode of life." This appeal to adaptations is not uncommon ; but we now know enough of the system, to believe that the relations of its parts are to be determined by homological and embryological considerations combined, which coincide also with chronological and geogra- phical. Have we not creatures of similar habits and adaptations in the most diverse groups? It is enough to mention to a herpetologist the arboreal Viperidce and Crotalidas ; the corresponding types of Pleodonta and Ccelodonta, of Acrodonta and Pleurodonta; the gill-bearing Siredonand Siren, and a host of other such ; the parallelisms of the Implacental and Placental Mammalia, etc. Also the supposed Neotropical Shrikes and Certhiidse are Clamatores, and the supposed Salmonidse are Characins. In comparing many of these cases, we observe, too, how by approximation in time, analogy becomes affinity. In pursuance of this view, the probability of a distinction between the Hylodidae and Cystignathidae of Giinther has appeared to the author to vanish in great mea- sure. The discovery of the genus Tarsopterus of Reinhardt and Liitken, in con- nection with that of Plectromantis, by Wagner, has confirmed this opinion. The two genera are incontestably nearly allied, as urged by Reinhardt.|| though the * Classif. der Batrachier, 26. t Stannius' statement, "Zootomie der Amphibien," p. 17, that Pyxicephalus possesses the manu- brium, relates properly to the species now called Tomopterna, which were formerly included under that genus.

Their margined toes are but a step beyond those of certain Cystignathi ; their digital dilatations are as distinct as those of many Hylodidaj. The family of Cystignathida?, thus composed, would contain the types Platyplectrum Gthr., Limuodynastes Filz., Cystignathus Wagl, Pleuro- dema Tsch., ?Gomphobates R. and L., Ischnocnema R. and., Liuperus D. and B., Tarsopterus R. & L., Plectromantis Peters, Crossodactylus Bum., Bibr.,Fhjl- lobates Bibron, Hylodes i'ftz., (or the genera into which the last may be divided.) In this association the paratoids of Plectromantis have but little weight, as in Pyxicephalus in our Ceratophrydidre ; and it is probable that it will again be found that their presence or absence is immaterial in the definition of certain families in the Anura, although others may be well characterized by them, a3 in Gunther's method. The genera Pelodryas Gthr., and Scytopis Cope, with large paratoids will probably be referred to the Hylidae, which has been defined as destitute of them. Pyxicephalus cultripes. Ochntophrynus cultripes Rhdt. and Liitk., Videnskab. Meddelelser, etc., Kjobenhavn, 1862, p. 159. If we introduce the presumed genus Odontophrynus into Dumeril and Bib- ron's table of genera of Raniformia, the only character which seems to separate it from Pyxicephalus is the concealed tympanum of the former, as distinguished from its visibility in the latter. This character is sometimes of very little value, the tympanic disc being more or less distinct in different individuals of the same species of many Anura, in proportion to the tenuity of the epidermis. This is especially seen in species of Bufo. The text relating to Pyxicephalus americanus, however, settles all doubts, as it says, M Tympan imperceptible au travers de la peau." In their Latin diagnosis, Reinhardt and Liitken say " dentes** non in palato ;" but in the text, " To langagtige i midten ikke sam- menstodende Tandgrupper ere stillede paa Ganen mellem de indre Naesebor," etc. As the figure represents palatine teeth, they are doubtless present. The species cannot, therefore, be separated from Pyxicephalus. It is very nearly allied to, if not identical with, the frog called Pyxicephalus ? n. sp., in the recently-published Catalogue of the collection brought home by the United States Paraguay Expedition.* ALYTID.E. SCAPHIOPCS. The species of this genus are seven in number ; they are found throughout the temperate regions of North America, and as far southward as the City of Mexico. They represent the single Alytes obstetricans of Europe, which differs in its want of manubrium sterni, its slightly-webbed toes, and its cunei- form bone forming but a tubercle ; and the Helioporus albip u n c t at us of Australia, where there is a spur upon the thumb, and trihedral diapophysis of sacral vertebra. They may be at once separated by means of the following synopsis : I. A gland in the upper integument of tibia. Head short; tympanum concealed mu Itiplicatus. II.

In the present condition of the species of Polemonium, I could not venture to add another to the list, if the present were notshown, by the fine suite of specimens now collected, to be a most distinct one It is probably (at least in the var. a) the very handsomest of the genus; and, as ripe seeds were collecti-d, it may be brought into cultivation. I cannot doubt Ibattbetwo varieties are of one species. The ampler limbof thecorollaof var.a (when fully expanded Sometimes ten or eleven lines in diameter,) often renders the funnel-form tube less conspicuous; but this form passes by gradations into those of var. /3, in which the narrow tube of the Corolla (9 or 10 lines 1 nig) three or four times exceeds the smaller lobes. Indeed, this connects Po- lem mium as closely with Tpom opsis as the latter is eonne 'ted with true Gilii. A high alpine form of var.a was collected by Dr. Lyall in the Rocky Mountains farther north, lat. 49, at the height of 8000 feet, having the verticillate leaflets o| the species, but a less exserted corolla. It was taken for P. viscosum-, Nutt.; but the minute leaflets of the latter are not verticillate or fascicled although much crowded, and its calyx and corolla are quite different, allying it to P. pulchellum. I make small account of the ovules, finding them to vary widely in number in 1'ffeiuut (lowers of the same inflore- ence; but in var. a, I have counted a dozen in each eeli , in var. /3, usually only 4 to 6. The anthers are more oblong than in P. Cieruleum. Bewate of the change of shape which the effete anthers undergo: when dry, they are short-oval, when soaked they become elongated-oblong, as P. Richardsonii is figure 1 in Bot. Mag. In like manner those of P.'cxruUum change from rotund to short-oblong. 1863.] 6 74 PROCEEDINGS OF THE ACADEMY OF mens of P. pulcherrimum ; both of which, -with F. capitatum, etc, do seem to pass into Arctic forms of P. cceruleum. 453.

Other specimens collected by Mr. H.

G. Engelmann. f Gentiana Pakrti, Eng., a narrow-leaved farm. Dr. Parry informs me- that the narrow-leaved varieties are often one-flowered, and their stems single, while the broader-leaved form (coll.

St. Louis, 2, t. 11 (ined.). is Dr. Parry's 440, a truly alpine, dwarf and very beautiful species, closely related to G. crinita, ciliata, &c. \ On examination of a series of specimens, Dr. Engelmann is inclined to view G. tenuis, Griseb. as an extreme form of G. acuta, and also to adopt the conclusions of those who regard the latter as specifically identical with G. Amarella of the Old AVorld. He adds the following note. Gentiana acuta, Michx. Undoubtedly an American subspecies of 6. Amarella. Messrs. Hall and Harbour have sent a large suite of specimens, which, together with Dr. Parry's (1861, Nos. 307 and 309), show an extreme variability in size, manner of branching and arrangement of flowers, shape and size of leaves, proportion of calj'x, size and color of corolla and size of seeds. 67. Engel- mann. | Dr. Engelmann remarks upon this, 1st. That the ovules cover the whole surface of the ova- rian cavity; 2d. That the structure of the corolla is that of Swertia, the nectarian glands at the base of the segments of the corolla being surrounded by a petaloid funnel with fringed edges; so that the curious lateral stigma principally separates the genus from Swertia.

Nine genera of this subfamily are now known to be represented by species along the western coast of America and the Gallapagos Islands. They may be thus distinguished : I. Caudal with the lobes acuminate. Lateral line before superior, deflected behind Pronotogrammus. Lateral line normal Brachyrhinus. II. Caudal not forked. A. Canine teeth developed. B. Dorsal spines XI. C Nostrils in a vertical row Mycteroperca. CC. Nostrils in a longitudinal row. Body oblong; smooth above lateral line Labroperca. , Body oval, with ctenoid scales Epinephelus. BB. Dorsal emarginated ; spines X. C. Head with profile decurved, scaly above.. Paralabrax. CC. Head conic ; naked between eyes. Spinous dorsal rounded Atractoperca. Spinous dorsal, incurved behind the third elon- gated spine Gonioperca. AA. Canine teeth entirely obsolete Dermatolepis. The preceding table gives only the more striking characters ; those are accompanied by others, which appear to amply authorize their generic dis- tinction. In the table, the genera do not follow each other in a strictly natural order. Genus PRONOTOGRAMMUS Gill. This genus has the form of Brachyrhinus. The body is covered by moderate, [Mar. NATURAL SCIENCES OF PHILADELPHIA. SI ctenoid scales. The lateral line runs high on the sides for the greater part of its length, but is abruptly deflected behind, and thence continued along the middle of the caudal peduncle. The head most resembles that of Brachyrhinus . The preoperculum is serrated on its posterior margin, and has a strong com- pressed spine at its angle. The operculum has three acute angles, the middle continued from an internal rib. The teeth are like those of Serranus, &c. ; two large ones exist on each side of the front, in the margin of the upper jaw, and one on each side, near the symphysis in the lower ; while there are also two on the sides. The vomer and palatine bones have villiform teeth. There are, apparently, only six branchiostegal rays. The dorsal is undulated, and has ten spines. The anal has three strong spines, the second of which is largest. The lobes of the caudal are acute ; the pectorals acutely rounded ; and the ventrals angulated. Pronotogrammus multifasciatus Gill. The greatest height equals or slightly exceeds a quarter of the length from the snout to the end of the median caudal rays. The head equals a third of that length, and contains the diameter of the eye, which is oval, three times. The snout is less than half the diameter of the eye. The spines of the dorsal rapidly increase to the fourth, which nearly equals a seventh of the length, and thence decrease to the last, which equals about an eleventh of the same. The longest ray about equals the longest spine. The second anal spine is more than twice as long as the first, equals the fourth dorsal one, and is con- siderably longer than the third anal one. The median caudal rays enter 6 times in the total length, while the longest exceed the greatest height. The pectoral fin commences little before the end of the first third of the length, (32,) and equals a quarter of that length. The ventral is inserted consider- ably in advance of the pectoral, ( - 28,) and is rather shorter than it. 1 D. X. 15. A. III. 6 P. 1. 14. V. I. 5.

The color is tawny yellow, with numerous (-20) rufous bands descending nearly to the middle, and rather wider than the tawny intervals. Only one specimen, whose extreme length was little more than two inches, was obtained. Family CEILODTPTEROIDJEBleeker. Genus AMIA Gronovius. The Monoprion of Poey is perfectly congeneric with the type of the genus Amia; the genus Apogonichthys of Bleeker appears to be at least very closely related to it, while both genera include forms that do not appear to be strictly allied, but more distinct from the types of the respective genera than the latter are from each other. The species of the old genus may be divided as follows : I. Preoperculum serrated. Anal II. 79 (10). 23 Scales 20 28 Amia. 58 Scales 33 36 [Apogon kalosoma, Blkr.) Lepidamia.

Amia and Apogonichlhys are probably the most closely allied groups. Family SPAROIDJE (Cuv.) Subfamily XENICETHYINJE Gill. XENICHTHYS Gill. Body moderately elongated and subfusiform, compressed, and with the caudal peduncle also compressed and robust. Scales deciduous, rather small, high and ctenoid. Lateral line tubular, in more conspicuous scales. Head compressed, conic, longer than high, with the occipito-rostral outline rectilinear. Upper surface of head to the nostrils covered with small scales. Occipital crest prominent. Eyes circular, large, and mostly in the anterior half of the head. Preorbital bones rather narrow and oblique. Operculum with two spines. Preoperculum pectinated behind, the teeth higher up pro- gressively directed upwards. Mouth rather small, with the lateral cleft very oblique, and not con- tinued to eye ; supramaxillary bones broad, enlarged in front below the intermaxillary, and behind the latter covered by a cutaneous flap from it. Lower jaw shorter than upper, but with the chin projecting beyond it, and with a pore on each side of the symphysis. Lower lip continuous and free at symphysis ; plicated behind, where it is received under the upper jaw. Teeth small, recurved, and in rather narrow bands on each jaw. Vomer with its projecting front provided with a villiform rhomboid patch; palatine bones and tongue edentulous. Nostrils above anterior, and in a line with upper margin of orbit, near each other; the anterior circular: the posterior cleft transversely. Branchiostegal rays seven on each side. Pseudobranchise present. Dorsal fins connected by a low membrane at the base; the first with ten rather slender but perfectly rigid spines ; the third, fourth and fifth of which are longest, (with no recumbent spine in front) ; the membrane has a fibrous appearance. Second dorsal lower than the first, and elongated. Anal fin about as long as second dorsal, but rather farther back, with three small, regularly increasing spines. Caudal fin emarginated, with rounded lobes. Pectoral fins small, with the upper angle produced, but apparently rounded. Ventral fins inserted close behind the pectoral : each with a spine and five branched rays, and a pointed axillar scale. As there might be some doubt as to the affinities of this genus, on account of the few palatal teeth and the number of branchiostegal rays, an extended' description of its generic characters has been given. The spinous dorsal be- ing received in a groove, the upper jaw closing under the preorbital bones and axillar ventral scales existiug, it belongs to the family of Sparoids, as now modified. It cannot be referred to the Sciaenoids, as its skull is smooth. The nearest allied genus appears then to be Moronopsis, [Dules marginatus C. V.*) That genus differs in its more compressed body, the scales and the similarity of those of the lateral line to the others, the stouter dorsal spines, * The Dates auriga and D.flauiventris are, of course, not regarded as allied to D. marginatus , &c. I am unable to perceive any affinity between them, and they have been united only in accord- ance with an artificial system. [Mar. NATURAL SCIENCES OF PHILADELPHIA. 83 between which the membrane is acutely notched, the scaleless crown and little development of the occipital crest, the dentition and the number of branchiostegal rays, and, finally, the absence of axillar scales. With any other form it is unnecessary to compare the genus, as its natural affinities appear to be more intimate with Moronopsis* than any other. Naturalists can decide from the above enumeration of the differential characters, in compari- son with Moronopsis, if there is any other group to which it could be more naturally approximated. If it is stated that the physiognomy of the two genera is quite similar, the chief difference being caused by the procurrence of the occipital crest and the rectilinear profile, as well as the character of the scales, the ichthyologist can appreciate the aspect of the newly-described form. Xenichthys xanti Gill. The greatest height equals three-tenths of the length (exclusive of the caudal). The head forms a third of the same. The diameter of the eye equals a third of the head's length, is about a third greater than the interorbital area, and nearly a third greater than the length of the snout. The fourth or longest dorsal spine equals nearly a fifth of the total length, and is nearly five times longer than the tenth. The third or longest anal spine is scarcely more than a twelfth of the length. The pectoral fin at least exceeds a seventh of the length, while the ventral equals a seventh. D. XII. 14. A. III. 17.

The color below is silvery. At the base of the caudal there is an indistinct spot. The tip of the spinous dorsal fin is dark. This most interesting and even remarkable type is dedicated to Mr. John Xautus, to whom we are indebted for the noble collection of fishes and other animals of Lower California, and who has, more than any other single man, contributed to our knowledge of the natural history of the Western coast. Family CARANGOIDJE. Genus ARGYRIOSUS Lac. Two representatives of this genus are found on the Atlantic coast of the United States : they are the A. vomer, of Linnasus, and the A. capillaris, Dekay, the A. unimaculatus of Batchelder and Storer, and the form which has been considered by Gunther as the young of A. vomer or a new species, appears to me to be the young of Vomer selipinnis, and at least belongs to the same genus. The Argyriosus Spixii of Castelnau is the unfortunate Selene argentea of Lace- pede, first well made known by Mr. Brevoort, but which has received a num- ber of names from different writers. Argyriosus Brevoortii Gill. The greatest height in an oblique direction nearly equals nine-tenths ('87) of the length in a straight line, from the vertical of the snout to the end of the median caudal rays. The head forms less than a third of that length. The profile is oblique, and slightly incurved below the angular crown ; its distance from the vertical of the snout equals an eleventh of the total length, and be- fore the eyes, two-thirds of the preceding. The diameter of the orbit equals an eleventh of the length, and its distance from the profile equals two-thirds of the diameter. The height of the preorbital is twice as great as the diame- ter of the orbit. The base of the arched portion of the lateral line equals three-tenths of the total length, and its elevation above the horizon equals a *The Datnia? ambigua of Kichanlson, which has been referred by Gunther to the genus Dules differs from Moronopsis by the shorter convex anal fin, the large second anal spine, the small eyes and the entire physiognomy.

The second dorsal spine is very long ; the third little longer than the base of its fin. The caudal lobes diverge at nearly a right angle ; the length of the lower nearly equals three-tenths of the total. The pectoral fin equals a quarter, and the ventral two-fifths of the total length. D. VIII. I. 22. A. II. I. 18. The color is silvery, punctulated, with black near the edge of the back, and withablack baronthehead above the eye, parallel with the forehead. The fila- mentous dorsal spines and the elongated dorsal and anal rays are blackish. The ventrals have the terminal half blackish, and the other whitish, with a median black band. This species is distinguished by its proportions, oblique profile, lateral line and color. It may be further remarked that the branch of the lateral line ascend- ing from the scapula divides into two branches, diverging at less than a right angle ; the anterior branch appears to be a groove. I have dedicated this species to my excellent friend, Mr. Brevoort, who has paid much attention to the group of fishes of which the present is a member. Genus HALATRACTUS Gill. Halatractus dorsalis Gill. The greatest height equals a quarter of the length to the end of the median caudal rays. The head enters more than three times and a half (-28) in that length. The diameter of the eye equals a quarter of the head's length, and is shorter than the length of the snout (=-09). The median caudal rays forms an eleventh of the length, and the longest equal a fifth. The pectoral fin nearly equals a seventh ('13), and the ventral nearly a sixth ( - 16) of the length. D. VII. I. 37. A. II. + 1. 21. P. 2. 19. The color is brassy, purplish on the back, and with ten indistinct darker bands, twice as wide as their intervals ; the second between the second and fifth dorsal spines. The dorsal and anal fins are nearly black; the anterior angle of the latter lighter. The ventrals dusky, with the rays externally white. This species is most nearly related to Halatractus zonatus Gill, and H. caro- liniensis, Gill, of the Eastern American coast; but readily distinguished by the color and proportions. Genus TRACHYNOTUS Lacepede. Trachynotus Carolincs Gill. This species is extremely variable, as are also the other well-known repre- sentatives of the genus. In extreme youth, the jaws and palate are dentigerous, and the angle of the preoperculum armed with three radiating spines ! while the spinous dorsal and anal are elevated, and the angles of the soft fins scarcely produced. Later, the preopercular spines become obsolete ; then the palatal teeth are lost ; the spines of the fins meanwhile become abbreviated, and , finally, in old age, the teeth have entirely dropped out, the spines become much shortened, and the angle of the fins considerably produced. Half- grown specimens answer to the genus Doliodon, of Girard ; nearly mature ones, with teeth in the jaws, Trachynotus, C.V. ; and old ones, without teeth, to Bothrolxmus, Holbrook. Relying on the correctness of my predecessors, who had certainly the opportunities, if they had availed themselves of them, to avoid such errors, I adopted the several genera proposed by Holbrook and Girard in my Catalogue of the Fishes of the Eastern Coast; Gunther first corrected the synonymy as lately given, and, under the other North American species, has brought together nine of Cuvier's species and two of other authors !

The head forms scarcely more than a quarter of the length. The diameter of the eye exceeds a third of the head's length, and is a third greater than the length of the snout. The latter is as high as long, and truncated. The lower jaw is not received within the upper. The spinous dorsal from the third spine arched, and highest at its fifth spine, which equals an eighth of the length. The first two spines are short. The second anal spine equals a tenth of the total length. The median caudal rays form nearly a sixth of the length, and nearly equal two-thirds of the longest ones, or of the head. The pectoral fin is contained about five times and a half in the length. D. VI. + I. 20. A. II. + I. 18, 19. The color is bluish-silvery ; the spinous portions of the dorsal and anal fins punctulated with black ; the ventrals rose-colored ; the other fins yellow- ish and mostly immaculate. Numerous specimens of this species were obtained by Mr. Xantus ; but all of them are young, (between one and two inches long,) and have the three radiating spines, &c, of the preoperculum. It must be remembered that the portion of the description referring to the spinous and soft dorsal and anal fins, is only applicable to the young ; the adult doubtless resembles Trachy- notus Carolinus. * The present species is allied to the latter, but at once distinguished by the small number of dorsal and anal rays. The radial formula equally distinguishes it from all previously known species having the same form. The young of Trachynotus ovatus, Gthr., does not essentially differ in form from the adult. Trachyxotus nasutcs Gill. The greatest height equals two-fifths of the length from the snout to the end of the median caudal rays. The head forms three-tenths or more of the length ; the snout is produced and subconic, and equals the diameter of the eye, and scarcely less than a tenth of the head's length. The lower jaw is received within the upper. The spinous dorsal is highest at the fifth spine, which equals an eighth of the length, or nearly a third of the height of the body beneath. The second anal spine is as long or longer than the fifth dorsal one. The median caudal rays form an eighth or more of the total length, while the external rays only equal a sixth of the same. The pectoral fin is contained five times and a half in the length. D. VI. -f I. 20. A. II. + I. 19.

Several specimens were obtained, mostly under an inch long. The description of the dorsal and anal fins, as in Trachynotus rhodopus, refer only to the young. Trachynotus fasciatcs Gill. This species is closely related to the Trachynotus glaums of the Atlantic and Caribbean Sea, but is distinguished by the scarcely gibbous snout and the distribution of the vertical bands : the first commencing close in front of the first (erect) dorsal spine ; the second between the fourth and fifth, and the third under the fourth and fifth rays. A black spot also appears to exist on the lateral line below the seventeenth dorsal ray, and a black blotch behind the dorsal fin. The produced dorsal and anal lobes are nearly coterminal with the caudal lobes. A single dried specimen, nearly eight inches long, was given to the Smith- sonian Institution by Capt. John M. Dow. The snout is doubtless always less gibbous than, or rather not vertical as in, T. glaucus. It cannot be the more mature form of T. rhodopus or T. nasutus, as the snout, when it does change, becomes more elevated with age. The colors are also quite different, and pro- bably undergo no essential change with age. Family SPHYR^NOIDjE Ag. SPHYRiEXA LUCASANA Gill. The greatest height equals a tenth of the length, and is a quarter the thick- ness. The head forms about three-tenths of the length. The snout enters 2\ times in the head, and is more than twice as long as the diameter of the orbit ( - 05). The maxillary bone ceases at a vertical, whose distance from the orbit equals the diameter of the pupil. The tip of the lower jaw has a square, thick flap. The first dorsal fin commences more than four-tenths ( - 42) of the length from the lower jaw ; its second spine rather exceeds the width of the body (08) ; the second dorsal commences more than six-tenths (-62) from the jaw, and is rather lower than the first ( - 07J). The caudal enters 6 times in the whole length. The pectoral fin extends for about two-thirds of the distance between its base and the ventral, and is less than of the length (-07). The ventral is rather longer than the pectoral, and is inserted under the anterior margin of the first dorsal. The first dorsal commences about over the thirty-fifth scale of the lateral line, and the second over the ninetieth. D. IV. I. 8. A. 2. 9. Scales 134.

The greatest height does not equal a third (-31) of the total length ; the tail behind the vertical fins nearly equals a ninth of the total length, and nearly the length of the base of the rays ; its least height is rather less than a twelfth (-08) of the same. The head, from the snout to the opercular margin, forms more than a fourth ("26) of the length ; the opercular spine is long, and nearly equals a third of the diameter of the eye ("03). The preo- percular spine extends to the vertical from the base of the opercular one. The diameter of the eye equals a tenth of the total length, and is a third greater than the length of the snout (=-07). The preorbital has six or seven moderate teeth, directed backwards. [Mar. NATURAL SCIENCES OP PHILADELPHIA. 87 The spinous dorsal commences above the posterior margin of the scapular bone ; its first spine equals the eye's diameter ( - 10), and the third is a half longer ( - 15). The second dorsal at its longest rays rather exceeds an eighth (=13) of the total length ; it ends over the twenty-fifth scale of the lateral line. The anal fin is somewhat larger than the second dorsal ; the third spine is very large, its length entering nearly five times and a half ( - 18) in the total. The caudal fin forms more than a fifth (-21) of the length, while the median rays only equal a tenth. The pectoral and ventral fins are equally long, and rather less than a fifth (19) of length. D.

The Echencis osleochir of Cuvier and the E. brachypterus of Lowe should both be removed from this genus and accepted as the types of as many distinct ones. The E. osteochir is distinguished by the rhombic form of the pectoral fins and the ossification of the rays. I have therefore named the specimens in the Smithsonian Institution Rhombochirus osteochir. The E. brachyptervs is distinguished by the shorter anal fin and angular upper jaw.

Descriptions of some new species of PEDICTJLATI, and on the classification of the group. BY THEODORE GILL. The group called by Cuvier Acanthopte'ryrjiens a pcctorales pediadees and estimated as a family, is a very natural one, distinguished by the incom- plete ossification of the skeleton, the prolongation of the carpal bones tc form " pedicles" for the pectoral fins, and, finally, by the abnormal position of the very small branchial apertures. "While these characters are not sufficient to entitle the group to ordinal distinction, they seem to be of much more than family value ; it may be called a suborder, for which the name Pediculatim&j be retained. The genus Batrachus, referred to the Pediculati by Cuvier, has really little affinity to the true representatives of the group, and has been, by general consent, separated from them by all the more modern systematists. In the suborder, four very distinct types distinguished by difference of form and structure are comprised. Those types must therefore be regarded as rep- resentative of as many families. Dr. Bleeker has attempted to distribute the several genera among families, which have not been characterized, but which were evidently separated on account of superficial differences of form. This is apparent on an examination of his system. Phalanx 1, Herpetoichthyes seu Pediculati, Cuv. Ordo 15, Antennarii. [Mar.

The disk is longer than wide, and somewhat oval, being narrower before than behind. The ridges alone are covered with simple spines ; five spines form a pentagon before the interorbital area; one over each orbit, and four are on a ridge proceeding backwards from the posterior angle of each orbit, which converges in a curve towards the opposite one ; the last form the anterior angles of a transverse pentagon on the nape. A transverse ridge behind the eyes, which intersects the longitudinal ones, and has at the angles the second spines from the eyes, provided near each lateral end with another spine, and a swell- ing at the end itself.

The skin is covered with bifid spines. The body and fins are fawn-colored, lighter on the abdomen, with a few scattered ocellated dots, more abundant on the internal face of the pectoral fin as well as ventral ; the abdomen has darker fawn spots. There are larger ocelli, black, edged with white, on the marginal half of the dorsal and anal fins, and on the caudal ; on the latter, three larger ocelli form a tri- augle. A still larger ocellus is on the back at the base of the ninth dorsal ray, and another between the fourth and fifth anal rays. A pink spot exists at each corner of the mouth ; the second dorsal spine and streaks on each side of its groove are colored likewise, and in front of the dorsal is a pink triangular saddle, sending from each anterior angle a fawn streak margined with whitish to a pinkish area before the pectoral, above which it merges in a marbled fawn area. A broad pink ring encircles the base of the caudal fin, which it- self, as well as the posterior half of the dorsal and anal fin, have a submargi- nal pink band. A single specimen was obtained by Lt. Wright. U. S. A., at Garden Key, Florida, and is in the collection of the Smithsonian Institution. AxTEXNARIUS PLEUROPHTIIALMUS Gill. The anterior dorsal equals about a third of the length of the caudal fin, and has at its end a laciniated or fringed lobe extending upwards ; the second is moderate, slightly curved, and rather longer than the first, and with a mem- brane extending nearly to the base of the third spine; the latter is free, ex- tends backward nearly to the fin, and almost connected with it by the mem- brane. The skin is covered with minute bifurcated spines. The color is brown, marbled with lighter, especially before and behind the dorsals, and above the pectorals ; distant black dots are also scattered over the body. Three large ocelli or black spots, margined with light-brown, are on each side ; one at the middle of the basal half of the dorsal ; a second below, intermediate between it and the anus, and a third in the middle of the caudal tin. The floor of the mouth behind the tongue is black, with whitish-yellow radiating lines, while the tongue itself is light-brown, with darker radiating bands or spots. A single specimen of this species is in the collection of the Smithsonian In- stitution, and was probably obtained at Key West. Antennarius strigatus Gill. The anterior dorsal spine is very slender and filiform, without appendages ; the second is straight and moderate ; the third concealed and only developed as a hump, obtuse behind. The spines which cover the body are small and mostly bifid. The back and front of the dorsal fin are reddish ; the rest light-brown, with black stripes which diverge downwards above the pectorals, those in front being parallel with the profile, and at right angles with those behind. Around the pectoral fins and on the flanks, the streaks are generally blended to form a continuous black area. A black dorsal saddle is in front of the dorsal fin, and a black band covers the posterior half of the caudal fin. The abdomen is broadly reticulated with black, and the brown intervals themselves are fre- quently striated with the same color. The interior of the mouth is immacu- late. ("ape St. Lucas, (J.

Hayes in his Eiploration of Smith's Sound, between parallels 78th and 821, daring the months of July, August and beginning of September, 1861. BY E. DURAND, THOS. P. JAMES AND SAML. ASIIMEAD. Although the following enumeration does not contain any new plants, it is,, nevertheless, sufficiently interesting in other respects not to be passed un-' noticed. la a geographical point of view, it exhibits the peculiar regetation of the most northern portion of the globe as yet visited by civilized man, and illustrates several facts which are not devoid of interest. In his Arctic exploration, Dr. Hayes has been very active in collecting specimens in the different branches of Natural History, which he has liberally presented to the Philadelphia Academy of Natural Sciences. His botanical collection, which was placed in my hands, was not so numerous in species as that of his predecessor and former Arctic companion, Dr. Kane ; but the latter had collected along the whole western coast of Greenland, from 65 a upwards, whilst Dr. Hayes' collections have been confined to the limits of the 7Sth and 821 parallels, where, naturally, a greater scarcity of species was to be ex- pected. From those extreme Arctic latitudes, in which the thermometer of Fahren- heit scarcely ever reaches 55 J , with the ground continually frozen and mostly covered with snow, Dr. Hayes brought seeds, apparently in a perfect state of maturity ; and also some living roots, imbedded in their own rich soil, and carefully packed in boxes. Among those roots, with their somewhat withered stems, could be recognized Salix Arctica and S. kerbacea, Tqfieldia puhistris, and/2 munculus nivalis, large tufts of Andromeda tetragona,Armeria Labradorica, Sileneacaulis, &c. All these, at their arrival in Philadelphia, in the beginning of January, 1862, were entrusted to the care of our fellow-member, Mr. Kil- vington, a skilful horticulturist, who resorted to every means his experience and ingenuity could suggest, to insure their vegetation. Some of the seeds, those of the Crucifera especially, germinated well and put forth the primordial leaves ; the roots began early to show signs of vegeta- tion ; the buds of the willows enlarged, but never arrived at expansion. An- dromeda gave some hope of success, and Lycopodium annotinum and a species of Hyp mini resisted the longest. But as soon as the plants ceased being supplied with ice and snow, they began to droop and die, the one after the other, and, by the middle of April, not one of those Arctic denizens, except Hypnum, remained to enjoy the sweets of our Philadelphia spring. Another remarkable fact : The Arctic soil, in appearance so rich, in which the roots were imported, had been found to contain numerous seeds that had given expectations of a good harvest of hyperboreal plants. Mr. Kilvington carefully watched them, early in the spring. They were seen, gradually, to swell and burst, but no sign whatever of germination took place in them. Nor in the whole course of the summer and autumn to this day, has that ground produced a single plant germinated from the seeds that must inevitably have been disseminated over it from the neighboring plants in the garden. Incited by the apparent richness of that Arctic soil, Mr. Kilvington planted in it some species of Erica : but they, also, soon languished and would have died had they not been removed to a more genial ground. Evidently, that Arctic soil had become perfectly unproductive out of its ever-frozen zone ! E.

Almost all the specimens of Dr. Hayes were with narrow, entire leaves, but scune exhibited the intermediary forms of both varieties, and a single one was a perfect specimen of Dryas octopetala. t Dr. Jos. D. Honker, in his ' Outlines of the Distribution of Arctic Plants," (Trans. Linn. Soc.

Dr. Kane's specimens belonged probably to the same form; but having no fruit on, I referred them, naturally, in my Plantie Kaneanne, to Empetrum nigrum. It is a remarkable fact of geographical botany, that this red-fruited species, originally found on the shores of the Strait of Magellan, should appear again at the opposite extremity of the American continent. Messrs. LaPylaieaud Tuckerman met with it in Newfoundland, and, quite lately. Abbe Ferland, a Cathmlic missionary of the Laval University of Quebec, found it likewise on the coant of Labrador, together with Empetrum nigrum. 1863.] 9G PROCEEDINGS OF THE ACADEMY OF 71, 74. 75. 76. 77. 78. 79. 80. 81.

The common tint of the dorsum is a very dark reddish-brown, but it varies greatly, in some specimens being as light as the legs, in others even olive. In the typical pattern, whilst the penultimate caudal segment is of the same reddish-brown as the body, the terminal is very light. The cephalothorax is broad, and has its surface minutely granulate. The median furrow is strongly pronounced, and is intersected by three transverse crosses. The most anterior of these crosses is at the position of the median ocelli ; the most posterior just in front of the hinder margin. Rarely these are somewhat obsolete, and some- times tbey are slightly oblique. The opposing edges of the fingers are armed with obliquely longitudinal imbricated rows of small teeth, with a series of larger distant ones on each side. The surfaces of the abdominal scuta are quite smooth, but their posterior borders are tuberculate. Anteriorly they are impressed with two crescentic linear furrows. The legs are compressed and hairy ; their edges are more or less crenulate. The tail is long, massive, rough and very hairy. At the proximal end of each of the first four joints, there is a pair of broad, thin, minutely denticulate articular processes. On the distal extremity of the fourth there is a nondenticulate pair. The su- perior, supero and median lateral crests of the first four articles are strongly but irregularly crenate. The median is evanescent, on each, anteriorly. The inferior and infero-lateral ridges are smooth on the two anterior joints, on the third they are slightly, on the fourth distinctly crenate. The supero and me- dian lateral crests of the penultimate segment are strongly crenulate ; the infero lateral and median inferior strongly denticulate. The last joint is short, swollen and very hairy. Its articular processes are large, but not dentate. Its superior surface is triangular, smooth and complanate, or even depressed ; its inferior is tuberculate, and traversed by two grooves on each side.

Tbe color of our single specimen is an olive-yellow tint, witb a very dark crescentic blotcb at the position of the median eyes. But in this pattern it does not differ from some individuals of the preceding species. The cephala- thorax differs from that of B. hirmtus only in one character : In its anterior border is a very large emargination, which reaches about one-third of the dis- tance to the melian eyes. The abdomen is precisely like the preceding species. The tail is perhaps a little less massive. But it also so closely re- sembles that of B. hirsutus the description of one will answer for the other. Length of body, 1 5-8 inches : of tail, 2 5-8 inches. Lower California. J. Xantus de Vesey.

The surface of the cephalothorax is rough and uneven. The hands are very small and smooth, with some traces of the eight facets so distinct in E. punctipalpi. The fingers are about as long as the hand, rather slender, with their opposing margins armed with a row of very sharp, minute teeth, and much larger ones placed at intervals on one side of their distal portion. The legs are somewhat compressed ; very long and slender. The tail, when com- pared with the boly, is very heavy. On the first four joints the superior and supero lateral crests are alone serrulate. The superior terminates in a spine, feebly pronounced on the fourth article. The inferior and infero lateral crests are distinct, but not crenulate. The penultimate segment has well-marked, but not crenate, supero and infero lateral ridges, besides a single median infe- rior and median lateral on their proximal portion. The terminal joint resembles that of B. punctipalpi, but is much larger and thicker, and not so prolonged posteriorly. Sternal plate pentangular. Length of body, $ 7 lines : of tail, tf 13 lines.

All of our specimens are immaculate ; some of them shade off in color to- wards an olive. The lateral eyes, three in number, are generally arranged in a slightly, but occasionally in a strongly curved line. The cephalothorax, and, indeed, the whole dorsum is roughened by very numerous minute tuber- cles. The scuta are more or less distinctly medianly keeled. The joints of the palpi are irregularly parallelopipedal, with their margins mostly well- 1863.] 110 PROCEEDINGS OF THE ACADEMY OP defined and crenulate. The second joint has on its anterior face one or two crenate ridges ; its posterior margin is rounded off. The hands are large, and have only their superior and inferior edges distinctly crenate. The fingers are robust and moderately long, with their opposing margins armed with a single row of teeth, with larger ones at regular intervals on one side of their distal portion. The feet are compressed. The tail is rather robust. The first three joints have their superior and supero lateral ridges sharply serrate, and terminating posteriorly in a spine. In the fourth they are the same, except that the terminal spinule of the supero-lateral crest is wanting. The first four joints have infero lateral and inferior crests, the former mostly distinctly, the latter indistinctly (excepting on the posterior segment) serrulate. The penultimate articulation is long, and armed with distinctly serrulate supero- lateral, infero-lateral crests, as well as a single median inferior; and on its an- terior half, central lateral ridges. Its form is that of a parallelopipedon thinned at its two extremities. The superior surface of the last joint is trian- gular and complanate ; the inferior is convex.

The color of this species varies ; generally each abdominal plate has a dark brown v or w shaped marking, forming a continuous stripe on each side. This is obsolete on the cephalothorax. But this distinctness of pattern is often lost, and the whole body involved in an olive-brown tint. The palpi closely resemble those of B. boteus, but have the hand not so large, and the facets and elevated lines not so strongly pronounced. The opposing margins of the fingers resemble those of that species in their armature, but want the wavy outline. On each side of the abdominal median line are numerous small black tubercles, so arranged as to form more or less prominent ridges. There is also a series of these on the posterior border of each of the abdominal scuta. The legs and tail are of a dirty yellow color. The anterior four caudal joints are short and very robust, the breadth of the first three often equalling their length. These four joints are provided with denticulate superior and supero- lateral crests. In the anterior three these are of nearly the same length, and terminate distally in a small spine. In the fourth, the dorsal is only two- thirds the length of the other raised line, and the joint is then scooped out to the level of the latter, which does not end in a spine. On the first four articulations the middle lateral crests are almost entirely obsolete. On the fifth they are more strongly pronounced. This joint is much more elongate than the others. Its supero-lateral crests are not so strongly denticulate as those of the others, and have no spine at their distal extremity. The in- fero-lateral and inferior crest exist on the first four joints as four black, oc- casionally somewhat obsolete, ridges, but are not crenulate. On the fifth both the inferior-lateral and the single median-inferior crests are denticulate. The sixth caudal joint is somewhat ovate, flattened above, and without ridges. On the lower surface there exists a faint mesial groove. The sting is slender and strongly curved. Length of body, tf 9 one i ncn > f * a ^> ? one inch, two lines ; $ one inch, four lines. Hab.

The cephalothorax is not produced as far anteriorly as is commonly the case. It is impressed with a faint transverse groove at the position of the median ocelli, and with another, more distinctly defined, on its posterior third. These channels separate three pairs of slightly pronounced elevations, which successively decrease in size from the first. The first joint of the palpi has all of its margins armed with distinct obtuse denticules, excepting only the postero-inferior, which is rounded and concave, and crenate only on its proximal third. The third article is much larger than the second, and has only its anterior margins crenate. Its posterior surface, as well as that of the hand, is sparsely and irregularly punctate. The anterior aspect of the hand is minutely tuberculate. The first joint of the mandibles is very long, almost always extending as far forward as the cephalothorax, and often much beyond it. The distal portion of these organs, with the "pincers," is black. The median eyes are placed upon a single black elevation in the middle third of the cephalothorax. The first two lateral ocelli are somewhat smaller than the median ; the third is much smaller ; the fourth is at right angles to the third, and is still less. The three anterior joints of the tail are short and rather broad. Their superior crests are entirely, and their supero-lateral al- most, obsolete ; their inferior and infero-lateral are well-marked and broadly crenate. All of the ridges of the fourth segment are obsolete. The penulti- mate joint is elongate and slender. Its lower surface is rough, and has two strongly, but obtusely denticulate infero-lateral, and a single, median-inferior crest. The last segment is immensely swollen. Its distal portion is sud- denly and very strongly contracted, and then inflated slightly again, so as to form a knob, as it were, on the base of the sting.

The color of our single specimen is a very light orange. The cephalothorax has a median longitudinal sulcus distinct anteriorly, but evanescent posteri- orly. A short distance behind the centre of the cephalothorax is a well-defined transverse groove, extending nearly across one-third of its breadth. Posterior to this, and connected with it by the median sulcus (here very well marked), is a transverse furrow similar to the other, but only about one-third its length. 1863.] 112 PROCEEDINGS OP THE ACADEMY OF The three sulci are of a dark-brown tint. Besides these, there are on each side of the cephalathorax four dark, but more or less obsolete grooves. At the posi- tion of the lateral eyes on each side there exists a dark-brown spot, and between them and the anterior transverse groove is a pair of similarly colored round de- pressions. The maxillary palpi are of a more decided orange than the body. The second joint has its anterior face armed with eight or ten very small spines or spinous tubercles, and one or two larger ones. The spines on the lower margin of the third joint are longer than those on the upper. On each, the two nearest the body are much larger and more closely approximated than the others. Between the margins are a few very small spinules. The spinous tubercles on the upper portion of the posterior surface are more numerous than those on the lower. The fourth joint is dilated superiorly in its distal portion : where on the upper margin are placed three very long acute spines, with two or three much smaller ones. The lower margin has five spines, three of them being much smaller than the other two. The moveable finger is very long and acute. The upper surface of the abdomen has along the mesial line a double row of dark- brown spots, and on either side a series of blotches of the same color, one on each scutum. The legs and sides of the abdomen are very rough. The under surface of the abdomen is smooth. Huh. Lower California. Smithsonian Museum. J. Xantus de Vesv. May bth.

BY THOMAS B. WILSON, M. D., AND JOHN CASSIN. The classification of the lower forms of organized beings, on the assumption that they ought to be assigned to either the animal or the vegetable kingdom, has presented difficulties to naturalists which have proved insurmountable. The position of entire groups remains, apparently, as uncertain and undeter- mined in this respect as it ever was, and the conclusions and opinions of authors are so various that it is palpable that no considerable approach has been made to the solution of the questions involved, notwithstanding much very careful and accurate investigation and patient research. The difficulty probably originates in the first assumption, that all organized or living beings are referable to two great groups only, an assumption and presupposition of almost universal prevalence, but in which men of science seem to have been contented to adopt popular belief and to accept the usual and popular appli- cation of language. There are, very probably, three kingdoms or great pri- mary groups of organized beings, as distinct from each other as any subordi- nate groups and as readily defined by valid and recognizable characters. Whatever may be the solution, ultimately, of the very important questions relating to the primary, and at present unknown, principles under which the normal and inherent forces of Nature first assume that mysterious tension or condition, of which life is the immediate result, it is evident and unmistaka- ble that this extraordinary tension manifests itself and operates under such controlling laws that its results are determinate and uniform. Taking on themselves isolation from the great mass of inorganic Nature, though tempo- rarily only, these forces assume developments which are circumscribed and specific, though evidently progressive and modified under circumstances coin- cident with and dependent upon the laws or conditions of existence of organic life in any geologic period. It has hitherto been assumed, apparently, that from a point of the first manifestation of life, its progress of evolution or de- velopment is into two series or great classes of existences, animal and vege- table, or perhaps into one series only, according to the hypotheses of the older authors, regarded as the chain of being, from the lowest vegetable to 1863.] 9 114: PROCEEDINGS OF THE ACADEMY OP the highest animal. In our opinion it may be demonstrable, that the first assumption of life manifests itself in objects constituting a primary great class or kingdom of more simple organization than either the animal or vege- table kingdom, and possessing also an equally characteristic specialization in its structure and functions. The consideration of the question of determinable characters on the assump- tion of the existence of two primary divisions or kingdoms only may now safely be regarded as exhausted, without conclusive result or an approxima- tion to such, sufficient even to obtain general adoption temporarily as a pro- bable antecedent hypothesis, awaiting demonstration. Much has been at- tempted and numerous propositions and theoretical definitions have been thoroughly canvassed, to the end only of showing their insufficiency. Volun- tary motion and permanent fixedness, the presence or absence of nitrogen, internal or external stimuli, the differences in the method and substances of nutrition, and many other problems have, in their attempted solution, failed to give the desired formula, and there are those who may be presumed to be well acquainted with all the researches touching questions here alluded to, who infer summarily that there is no difference radically, or in the lowest forms of organization in the two kingdoms Animalia and Vegetabilia, as al- most universally supposed to be constituted. As an example, we cite the distinguished botanist Professor Lindley, of London, who says, in the Intro- duction to his standard and well known work on the Natural System of Bo- tany, " Plants are not separable from animals by any absolute character, the simplest individuals of either kingdom not being distinguishable by our senses," (p. 15, New York, 1S31). Of a somewhat similar tenor, but with an implication more in accordance with our views on this hitherto intricate subject, is an observation by Professor Owen, of the British Museum : " No- thing seems easier than to distinguish a plant from an animal, and in common practice, as regards the more obvious members of both kingdoms, no distinc- tion is easier ; yet, as the knowledge of their nature has advanced, the diffi- culty of defining them has increased, and seems now to be insuperable." (Hunterian Lectures, p. 2, London, 1855.) Inthe higher developments of the animal and vegetable kingdoms there is truly the utmost possible readiness of distinction, and this great facility seems to have led to an inference that the same readiness and facility ought to pre- vail throughout the two supposed kingdoms. "At first sight," says Professor Van der Hoeven, "it seems easy to distinguish an animal from a plant, and even the most unskilled person thinks he has a clear notion of the difference. Yet it is just his want of knowledge that causes the difference to appear so prominent, whilst he overlooks the intermediate links, and thinks, for in- stance, of a dog and a pear tree," (Handbook of Zoology, i. p. 4, Cambridge, 1856). We do by no means admit, however, that the principle here implied and apparently involved, which seems to be that the higher groups of any grade, whether kingdoms or other, are more easily recognizable and definable than the lower, is correct. The truth is, very probably, that the lower forms in all groups, are, at least, as readily to be assigned to their proper positions in the natural system as the higher ; possibly more so, in some instances. In the two kingdoms, Animalia and Vegetabilia, there is no difficulty with forms properly belonging to either of them, and of either high or low grade of development. The difficulty and, in fact, impossibility hitherto has been with organizations inferior to both, and properly belonging to neither. Though in an early zoological epoch the corals and other groups may have been regarded as of doubtful status, there is at present no group in either the animal or vegetable kingdom, rightly defined, which, in our opinion, presents any doubt or difficulty in its being assigned to either one or the other, and, probably, very generally, nearly correctly according to its actual or relative rharacters and its affinities. [May, NATURAL SCIENCES OF PHILADELPHIA. 115 There are clearly recognizable characters distinguishing the two primary divisions, or first duality of natural productions, organic and inorganic bodies, or, as Linnaeus judiciously terms them, corpora organisata and corpora con- pesta, and all the subordinate groups and species of either, necessarily possess characters in common, though exhibiting themselves in degrees of modifica- tions vastly diversified and numerous. In the former, or great organic di- vision, the definition of the common characters are of course implied in the term organic, and on the degrees and modifications of organization, whether indicating what may be termed higher or lower development ; whether clearly marking or only obscurely indicating inferior groups of whatever grade or value ; or whether presenting very prominent or very obscure modifications, with or without apparent object or relations on these degrees or modifica- tions of organization or structure rest all classification, and all the great pri- mary facts of independent existences, as presented to the human faculties, whether of observation or reason. We hold it to be altogether probable, and perhaps demonstrable, that all groups, of whatever grade or position, possess positive or relative characters dependent on, and exponating their degree of organization, and which characters absolutely establish and advertise then- status in Nature. We hold, too, that all such groups admit of description, and equally absolute or relative definition in language. Such is, and has always been, the practical faith of naturalists, whatever their theories, the accuracy of their observations, the extent and precision of their knowledge, or their deficiencies in either, and this faith is very probably quite truthful, and immutably founded on one important aspect of the relations of the ex- ternal universe to the human mind, mutually questioning and responding, calling to each other and answering gladly, as it were, like an echo. All the processes of naturalists, systematic or descriptive, are based on the assump- tion of the practicability of definition, and of groups, and of species alike. Any other course, or any other assumption, would be assuredly unreasonable and illogical, and destructive to the advancement of knowledge and of science. " We must trust the perfection of the Creation so far," says a distinguished author, " as to believe that whatever curiosity the order of things has awak- ened in our minds, the order of things can satisfy." (Nature, an Essay, by R. W. Emerson.) The organization of all beings, of which life is the essential character, seems to present three very distinct grades or specializations of development, and ap- parently indicates a classification based on such specialized development or the characteristic organs and functions of each grade. In our opinion the specialized organs and functions in each of these grades of development present sufficient and exclusive characters, admitting of being defined and applied readily as the real characteristics of three great primary di- visions or kingdoms of Nature. The term, specialized, has been used by Professor Owen with reference to the two kingdoms, Animal and Vegetable, and in nearly the same sense that it is used by us. He says, most truly : ''But the two divisions of organisms, called 'plants' and 'animals,' are specialized members of the great natural group of living things." (Palaeon- tology, p. 4.) The three great groups which we hold to be the primary di- visions or kingdoms of organic life, present, essentially as characters or spe- cializations of development, the prominence, or dominant prevalence of the Reproductive System, the Nutritive System and the Nervous System and their functions. The organs and corresponding functions which seem to characterize these three kingdoms, and to become specialized and dominant in the organization of each, are as follows : 1. Organs for the continuation of the species, the function of which is Re- production. 1863.] 116 PROCEEDINGS OF THE ACADEMY OP 2. Organs for the preservation of the individual, the function of which is Nutrition. 3. Organs for external relations and self-consciousness, the function of which is Sensation. The Reproductive and Nutritive functions are common to all organized beings, and so, probably, also is the Sentient function, though manifesting itself only in an incipient or rudimentary manner. The Reproductive func- tion, however, beginning with mere cellular conjugation, becomes specialized first in a great group of organized beings of more simple structure than either Vegetables or Animals, which we regard as eminently and demonstrably a primary division or kingdom, and apply to it the name Primalia. In this kingdom organs of Reproduction are temporarily formed, and no other. In the Vegetabilia, those organs become of greatly increased importance, though not permanent, and in the Animalia they present a still higher organization , and in the higher sub-kingdoms attain permanency of structure. The Nutritive function, beginning also in the cellular structure of our king- dom Primalia, is in that group quite rudimentary, so far as relates to spe- cialization of organs, but in the kingdom Vegetabilia, this function and the organs performing it, especially the organs of respiration and circulation, be- come specialized and assume an extraordinary degree of development. As- cending to the kingdom Animalia, the organs of Nutrition become more numerous and more highly organized in their structure, but the organs of Respiration are not developed to such extent as in the Vegetabilia. That the Sentient function is also common to all organized bodies is pre- sumable, or to be inferred only, from the fact that it is manifested in greater or less degree in the two first kingdoms, Primalia and Vegetabilia, in sensi- bility to light, to thermal or to meteorological influences, and occasionally to other external influences. It i9, however, generally held by Anatomists, but not without exception, that no organs of sensation are demonstrable in either our group, Primalia, or in the Vegetabilia. In the kingdom Animalia, and in that kingdom only, these organs are palpably most highly developed and specialized in the Nervous System. We recapitulate our views in the form of a corollary : 1. The Reproductive organs are first specialized in the kingdom Primalia. 2. The Nutritive organs are first specialized in the kingdom Vegetabilia. 3. The Sentient organs are first specialized in the kingdom Animalia. The possession of an organization exclusively providing for Nutrition and Reproduction characterizes the first and most simple forms of life. This or- ganization for Nutrition and Reproduction, and these functions only, is the especial character of the first of the three primary divisions or kingdoms of organized beings, the kingdom which we have named Primalia. In that group there are no other organs than those performing the function of Re- production, and the structure is exclusively cellular without vascularity ; or, perhaps it may be more properly stated to consist of mere unicellular ag- gregation. The possession of organs for, and the first development of the function of Reproduction is the specialization of this kingdom. The next great division or kingdom is marked by the high development of the organs performing the functions of Nutrition and the superposition or superaddition of organs providing for the co-operative or identical functions of Respiration and Circulation. The possession of organs providing for Nu- trition and Reproduction, Respiration and Circulation, and these only, char- acterizes the great group of Vegetables or kingdom Vegetabilia. In this group the vascular structure appears for the first time and continues to characterize it in all its modifications. The possession of organs for performance of the function of Nutrition in its highest development is the specialization of the kingdom Vegetabilia. The last or most highly organized kingdom presents an exclusive and pecu- [May, NATURAL SCIENCES OP PHILADELPHIA. 117 Mar character in the nervous system and its sphere of functions, embracing all the operations and relations of the senses and of the muscular system, super- added to the organs and the functions of the two preceding groups. The pos- session of organs for Nutrition and Reproduction, Circulation and Respiration, and for Sentiency, Voluntary motion, and all other functions and relations of the Nervous System, characterizes the great kingdom Animalia, Its specializa- tions is the possession of and the high development of the Nervous System. In imitation of the Liunaean formula these three kingdoms may be charac- terized as follows : Animalia, corpora organisita, generantia, spirantia et sentientia. Vegetabilia, corpora organisita, generantia, spirantia, non sentientia, Primalia, corpora organisita, generantia, non spirantia, nee sentientia. As above intimated, the difficulty in the hitherto attempted definitions and in the systematic arrangement of the kingdoms Animalia and Vegetabilia, on the antecedent supposition that these two kingdoms ought to include all or- ganisms that now exist, or have ever existed, has arisen from the impossibility of incorporating indisputably into either, many of those belonging to our third kingdom, Primalia. It is composed of orders and classes of existences, of which some have been very generally assigned to the Animal, and others to the Vegetable kingdom ; and others again which have been variously and doubtfully regarded as belonging to one or the other. All organisms included in this kingdom are of cellular structure only, and possess the functions of Nutrition and Reproduction, as above defined, and no other; and all the groups properly of this kingdom are, in our opinion, readily demonstrable, as having a greater degree of relationship to each other than to any groups whatever in the other two kingdoms. This circumstance is held, very properly, as of the first importance in all classifications. With this first, but quite inde- pendent great group recognized and understood, there is, very probably, no difficulty whatever in readily defining not only the three great groups of or- ganized beings, existing in Nature, but all subordinate groups belonging to either. We regard our third group as a Kingdom, and of the same rank or grade in classification as the two great groups which are universally admitted by naturalists under that designation. It is now a matter of common information to men of science that all organ- ized existences are composed of, and resolvable ultimately, by anatomical and microscopical analysis, into cells, and that the cellular structure prevails as a primary form or basis of organization alike in the most simple and in the most complicated organisms. Those cells seem to be the very first forms of organization and life, and possess a singularly independent vitality and power of increase or reproduction, whether isolated, or nearly so, or existing in any amount or form of aggregation in the higher vegetables or animals. They seem to be even capable of assuming, or re-assuming, individual and inde- pendent existence after having been previously and originally merged or ag- gregated in the vascular structure of the two higher kingdoms, Vegetabilia and Animalia, as well as in the lower non-vascular kingdom, Primalia. This seems to be the case in what are termed animal and vegetable infusions. The organisms constituting the kingdom Primalia are essentially to be re- garded as aggregations of cells entirely capable of nutrition and propagation, or increase, but without any part of their structure being traceable as vascu- lar in any degree. These organisms are the primary forms of life and organ- ization, and have not the distinctive characters or "super-additions," as termed by Professor Owen, of London, of either plants or animals. " When a certain number of characters concur in tLe same organism," says that learned gen- tleman, " its title to be regarded as a ' plant,' or an ' animal,' may be readily and indubitably recognized ; but there are very numerous living beings, es- pecially those that retain the form of nucleated cells, which manifest the common organic characters, but without the distinctive superadditions of either 1863.] 113 PROCEEDINGS OF THE ACADEMY OF kingdom. Such organisms are the Diatomacece, Desmidea, Protococci, Volvo- cince, Vibriones, Astasias, Thalassicolce and Sponr/ice, all of which retain the character of the organized fundamental cell, with comparatively little change or superaddition." (Hunterian Lectures, p. 8, London, 1855.) It is, in our opinion, quite expedient and reasonable to inquire whether either of the groups here mentioned, or any other, can possibly belong to the Animal or Vegetable Kingdom, without possessing " the distinctive superad- ditions of either." The indication in our opinion, is quite clear that these groups really do not belong to either, but t a third kingdom, not possessing, and definable without, those superadditions, and which we have above desig- nated. In his "Palaeontology," a work of later date than that just quoted, Professor Owen seems to have finally conclnded that the forms mentioned in the above citation do not belong to either of the kingdoms Animalia or Vegetabilia, and consequently he groups them into a kingdom for which he adopts the name Protozoa, (from Professor Goldfuss, Handbuch der Zool- ogie I. p xi. Nurnberg, 1820,) and says, "But the two divisions of organisms called ' plants,' and ' animals,' are specialized members of the great natural group of living things, and there are numerous beings, mostly of minute size, and retaining the forms of nucleated cells, which manifest the common or- ganic character, but without the distinctive superadditions of true plants or auimals. Such organisms are called ' Protozoa,' and include the Sponges or Amorphozoa, the Foraminifera or Rhizopods, Polycystineae, the Diatomace \ Desmidiee, GregarincB, and most of the so-called Poh/gastria, of Ehrenberg, or infusorial animalcules of older authors." (Palaeontology, p. 4, and Index, p. v.) The very appropriate term Protozoa is admissible for the group designated by Professor Owen, though the group or kingdom is very much restricted by him, and different from the group defined by Professor Goldfuss, and of en- tirely different grade or value. The latter learned naturalist divides all or- ganized beings into two sections, which he does not name, but which are the same as the divisions now well known as the Vertebrata and Invertebrata of Cuvier. He arranges the whole into eleven classes, of which Protozoa is the first, and Mammalia the eleventh class. The division of the class Protozoa is into four orders, Infusoria, Pkytozoa, Lithozoa and Medusince, which embrace sixteen families, or four families each, and include in the aggregate what must now be regarded as a very heterogeneous group, properly to be dis- tributed into all three of the organized kingdoms. The Protozoa are regarded by Professor Goldfuss as true animals. Professor Owen adopts the name for his group as restricted, quite properly, acccording to the usages of naturalists, the whole of it having been previously included in his class Protozoa by Pro- fessor Goldfuss. We have been thus particular in alluding to the term Protozoa, admitting its excellence, and willing to express freely our regret that we do not consider it proper to adopt it as the name of our first kingdom, on account of its having been applied originally to a group very different in all particulars. The king- dom now proposed by us, and which, in our opinion, is a natural and primary division, is composed of the following inferior groups : 1. Kingdom Primalia. 1. Sub Kingdom Algae. 2. ' ' Lichenes. 3. " Fungi. 4. " Spongiae. 5. " Conjugata. All of these groups are composed of organisms which are non-vascular and without organs of Respiration or Circulation ; and the kingdom Primalia con- tains all such organisms known to exist in Nature. But a comparatively small number of those belonging to our group Primalia are arranged by Professor Goldfuss in his Class Protozoa, but we regard it as containing the whole of the [May, NATURAL SCIENCES OF PHILADELPHIA. 110 Kingdom Protozoa of Professor Owen, and other large groups, as above desig- nated. The evident and insurmountable difficulty in arranging well known groups of inferior organization on the preconceived idea of the existence of two king- doms only, and that tho-e inferior groups must belong to one or the other, has led several naturalists into suggestions and propositions relating to a third kingdom, or other group of high grade. Usually, and, in fact, in nearly all instances, those suggestions take the form of mere intimations, or rather doubtfully expressed opinions that a third group is possible, and in the large majority of cases the intimation relates to the supposed existence of forms and groups intermediate between animals and vegetables. Occasionally doubts are clearly stated as to the propriety of regarding some specified forms as be- longing to either of the two great groups commonly received, and in a few cases the division of organized nature into three great primary groups, or kingdoms, has been proposed and presented in detail. The proposition of M. Bory de Saint Vincent is one of the most clearly de- fined. That distinguished naturalist, in " Dictionnaire Classique D'Histoire Naturelle," (vol. viii. p. 2-16,)* establishes an additional intermediate king- dom which he denominates " Regne Psychodiaire," and gives his conclusions on the existence of this third, but intermediate, kingdom in a very lucid and satisfactory manner, and with entirely judicious and proper minuteness of detail on such an important proposition. His views are mainly based on the fact that some organisms assume, at periods or stages of their existence, characters of both animals and vegetables, or, as he expresses himself, even of animals and minerals. He says : " Tous ces etres qui sont a la fois, des Animaux, des Plantes ou des Mineraux, et qui ne peuvent consequemment rentrer d'une maniere exclusive dans l'uu des trois regnes adoptes jusqu'ici, ne doivent-ils pas former un regne nouveau dont plusieurs naturalistes out deja reclame l'etablissement, et que nous avons le premier propose de fonder sous le nom de Psychodiaire." In volume xiv. of the same work, (Dictionnaire Clas- sique,) M. de Saint Vincent fully defines and expresses his conclusions in re- lation to his proposed new kingdom, (p. 329). He divides it into three classes, to which he applies the names " les Ichnozoaires, les Phytozoaires et les Litho- zoaries," the first of which groups embraces "les Polypes nus de Cuvier," and the second and third, the groups of organisms previously known as Zoophytes and Lithophytes as his proposed names indicate. Mainly the king- dom Psychodiaire of M. de Saint Vincent is identical with the Class Protozoa, of Prof. Goldfuss and subsequent authors, the difference being essentially that the former regards his proposed kingdom as a great group, equal in grade to the kingdoms Animalia and Vegetabilia, and intermediate between the two, while 'the latter regards his group only as a class of the Animal kingdom, and the first and least complex in organization of his eleven divisions of the grade of classes. This is, so far as our knowledge extends, the first arrangement or classifi- casion in Natural History in which three primary groups of organized beings are distinctly proposed. M. de Saint Vincent also proposes an additional in- organic kingdom, which he names the " Regne Ethere." In an article in the "Edinburgh New PhilosophicalJournal," vol. xii. new series (p. 216,) "On the distinctions of a Plant and an Animal, and on a fourth kingdom of Nature," by Mr. John Hogg, a British Naturalist, who has devoted much attention to the lower organisms, that gentleman proposes the name " Primi NATURAL SCIENCES OF PHILADELPHIA. 123 General Considerations. Before proceeding to speak in detail of the individual species of the Lestri- dinm, I desire to make a few remarks on the points which at the present day must be taken more especially into consideration, in carrying on an investi- gation of this subfamily of birds. Although the contrary was formerly the case, yet at the present time the species of Jiigers are pretty definitely ascertained, being better known, in fact, than the species either of Larince or Sternince. This arises partly from the fact of the small number of existing species, and partly because most of the species present really very marked differences, which can hardly be over- looked by any one examining specimens with an ordinary degree of mental acumen. With the amount of knowledge which we possess at present, it would be quite impossible to mistake Buffoni for parasiticus, etc., in whatever stages of plumage they may be found ; and therefore, except in one or two instances, I have thought it quite unnecessary to present any lengthy description or specific characters, for the purpose of separat- ing one species from another. In a paper like the present, such points seem quite uncalled for. At the same time, there is a point concerning which authors are even now at variance, and which seems to have need of all the light that can be thrown upon it. I refer to the remarkable changes of plumage which the species of one of the genera of this subfamily, Stercorarius, undergo in arriving at maturity, and more particularly that perplexing state in which the bird is uniformly dusky. From the time when Briinnich, in 1764, institutes a Catharacta " coprotheres, corpore toto fusco," etc., and then adds: "An a prsecedenti sexu vel specie diversa ? A quibusdam hsec pro foemina, ilia 127 (parasitica) pro mare habetur, " the question has been an open one. Some authors have made a distinct species of this stage ; others have given it as a variety ; others still have considered this plumage indicative of age, or of season, or of sex. Modern opinions have generally agreed in considering it as simply an evidence of immaturity, and not a variety, much less a distinct species. I hope I shall be able to show in the following pages, that this latter opinion is the correct one, even if I cannot prove exactly what age the dusky stage is characteristic of, or whether more than one sex participates in it. To this end, I have gone into detail regarding the various ages of two of the species, pomarinns and parasiticus. But there is still another point in the study of the Jiigers, which, being a matter of more than ordinary difficulty, demands our most patient and careful investigation. This is the bibliography of the subfamily. Many of the species were known to the very earliest, even pre-Linnsean, writers on ornithology ; and, as a natural consequence, the synonymy of the various species is as intricate, and in as puzzling a state of complication, as perhaps that of any other group of birds, rendering it a peculiarly difficult task to unravel the various knotty points which present themselves for our considera- tion. Fortunately, however, the synonymy of most of the species is rather intricate, than doubtful ; rendering it possible, perhaps, to present a tolerably accurate list of references, by careful and patient study. To this part of the subject in hand I have paid special attention, and it is believed that the lists of synonyms given are pretty full, and include all the important references. Others must judge of the accuracy of the citations, each according to his own views of the subject. If I seem to have made any uncalled for innovations in nomenclature, I can only offer as an apology, that it is impossible to conduct an investigation into the bibliography of the subfamily without seeing that many of the names in common employ must be superseded, provided we are to pay any attention to recognized laws of nomenclature. 1863.] 124 PROCEEDINGS OF THE ACADEMY OF Family LAR1DM.

Seas and sea coasts of the northern hemisphere ; more particularly in higher latitudes. It is quite unnecessary here to go into any details regarding the specific characters of so long and well known a species, and one which is so very dis- tinct both in form and colors from any other of our continent. I am well aware that the adoption of the name under which I present this species, may be looked upon by many ornithologists as an unnecessary, or at least as an uncalled for innovation. In defence of the nomenclature adopted, I beg leave to offer the following considerations, which, it is hoped, will ex- onerate me from the charge of needlessly changing names, by proving that if we are to pay any attention to recognized rules of nomenclature, such a pro- cedure is unavoidable in the present instance, and that no other name than the one adopted cau be used : In the first place, Moehring's genus Buphagus is certainly based upon a bird which was afterwards the Lams catarractes of Linnaeus. His diagnosis (vide in- fra*) unmistakably refers to one of the Lestridiiuc, while the species is fortu- nately exactly fixed by his reference to " Hojeri" and " cataractes." Perhaps no one of his diagnoses is more definite than this one. This being the case, the only question is, are his genera to be adopted and used in ornithology 1 I believe that the rule generally followed regarding Moehring's genera, is that they are to be adopted when they can be certainly identified, provided that they do not conflict with subsequent Linnaean appellations. Upon this principle, many of Moehring's old genera have been revived and adopted by Gray, and his example has been followed by Baird, and other ornithological writers. It is thus that such genera as Philomachus, Cullyrio, Trogon, Uria, Catarract.es, etc., have taken the precedence over more modern appellations, to which their priority entitles them. The rule, however, does not appear to have been so strictly carried out as it should be, if adhered to at all. Gray, for example, adopts Stercorarius of Brisson for the Jiiger, remarking ''that it is supposed to be Buphagus of Moehring." His procedure in this case is a little remarkable, since Bupliagus is certainly identifiable ; and there is no Linnaean genus with which it can conflict, Linnaeus ranging all the Jagers known to him with the gulls, under Larus. With this restriction, which, it must be confessed, is rather a compliment to Linnaeus, than strict justice to other writers, the genera of Moehring are to be adopted when identifiable. The fact of that author not being a binomalist, in fact, not dealing at all with species, does not appear to be a valid reason why his genera should be neglected any more than those of Brisson for example. I am decidedly in favor of the adoption for any genus of the first appellation that is proposed for it after the date of the first published works of Linnaeus, provided there be no conflict between them : considering the introduction of a definite form of nomenclature as beginning with that illustrious writer. Now, supposing that we do reject Moehring's Buphagus, let us see what will be the consequence. " Stercorarius Brisson 1760" is the name which of late has been most generally applied to the genus in question. But the type of Brisson's genus is not the catarrhactes,\ but the true parasitica, as is evident by his elaborate description, although no specific name is given ; and hence, if it is to be used at all, it must be for the genus of which parasitica is typical. But Brisson was a polynomalist ; and if we refuse to adopt Moehring's names on this score, Brisson's genera must also be rejected : to which procedure, of course, no naturalist would assent. Catharacta of Briinnich of 1764 comes next in order, and has as its type * Moehring. Genera Avium, 1752, page 66, No. 71. " Rostrum postice rectum, membrana callosa ad nares usque tectum, versus apicem incurvum, lateribus compressis. Femora extra abdomen. Digiti autici ties membrana intermedia toti cohaerentes, posticus liber." f Brisson. on page 165 of vol. vi. of his Ornithologie, ranges this species under Larus, calling it " Le Goelaud brun, Larus fuscus." [May, NATURAL SCIENCES OF PHILADELPHIA. 127 C. skua, which is the true catarrhactes. But here he is anticipated by Moehring, who had previously applied the name Cataractes* to a genus of Guillemots, of which Uria troile is the type. This genus has been adopted for the latter birds, by Cassin, Bryant, and others ; and, unless we admit the different spellings of the same word as distinct genera, which would seem quite unwarrantable, Briinnich's name must be superseded. Lestris of Illiger (1811) being based upon the parasitica, I am aware of no other genera than the above, which were founded on the Larus catarrhactes down to 1S56, when Bonaparte, in his Conspectus, proposed the name Megalestris. The choice then lies between Moehring's Buphagus and Bona- parte's Megalestris ; and of the two, I prefer to take the former, especially as by so doing we shall be enabled to retain Stercorarius of Brisson for the other species of the subfamily. Regarding the adoption of the specific name skua, I will merely remark that as Briinnich was as strict a binomalist as Linnaeus himself, there is no reason why his specific names should not be employed in all cases when they are identifiable. The date of Briinnich's "skua" is 1764; that of Linnaeus' " catarractes " is 1766. It is a little surprising that Brisson, after instituting the genus Stercorarius for the Jiigers, should be so far at fault regarding the proper affinities of the present species as to place it among the Gulls, under the name of Larus fuscus. His descriptions of all the Jagers are remarkably accurate, and so full and complete as to admit of the positive identification of all his names. In this case, and in numberless other instances, there is cause for exceeding regret that he was a polynomalist ; for, had he been a strict binomalist, so that we could adopt his specific names, we should be saved a vast deal of uncertainty and profitless discussion as to the proper specific appellations to be employed. The Larus keeask of Latham is certainly the present species. That author gives 22 inches as the total length, and 3 inches as the length of the bill, dimensions which will apply to no species of Stercorarius; and there is no other Buphagus than the present inhabiting the northern hemisphere. His bird "habitat in America ad sinum Hudsonis." The plate which Vieillot gives in his Galerie des Oiseaux, (1854) of his Stercorarius pomarinus, represents undoubtedly the present species ; and is, so far as I am aware, the only instance of the application of the name pomarinus to any other species than that to which it rightfully belongs. This error seems the more surprising, since Vieillot, in 1817 and in 1828 (vide synon.), gives the species as Stercorarius catarrhactes. The other synonyms' of the species do not require special notice. I have endeavored to preserve the various spellings of the word catarrhactes by the different authors cited. I quote Catarractes fusca Leach, and vulgaris Fleming, and Lestris skua Brehm, on the authority of Bonaparte. 2. Buphagus antarcticus Coues ex Lesson. Lestris catarractes, Quoy et Gaimard, Voy.

The fine series in the Museum of the Smithsonian Institution, pro- cured by the United States Exploring Expedition under Com. Wilkes, all differ from the skua of Europe and America in the possession of shorter, and comparatively stouter and deeper bills, with more obtuse tips. These are the only points of discrepancy I have been able to detect in the examination of the series ; but they appear to be quite constant. Among the series is a specimen much larger than the rest, and than the slcua from Europe. The bill is nearly two and a third inches long, and very stout ; the wings an inch, and the tarsus a third of an inch longer than the average of European skins. It is evidently a very old individual, and the chestnut and whitish have almost entirely disappeared from both the upper and under parts, leaving the whole bird deep blackish-brown above, and a somewhat lighter brown, or fuliginous, below. The specimen is referred to in Cassin's List of the Birds of the Exploring Expedition, as " Lestris ?" Although the general appearance of the bird is really different from that of the rest of the series, I do not think that the differences presented are any- thing more than indicative of the great age of the specimen. A collection of American and European Jiigers, obligingly furnished by Mr. D. G. Elliott for examination, contains a specimen of the true skua from the Atlantic Ocean, which presents a very similar condition of things. The size is greater than that of any other of the series of specimens, and the colors are nearly as uniform as in the antarctic specimen referred to. I think it more than probable that the birds of this genus continue to grow in size and proportions with increasing age, and that the colors have a tendency to become darker and more uniform under the same circumstances.

A single genus cannot, without great latitude and looseness of definition, be made to include all the species of this subfamily. The differences between Buphagus skua (with its southern representative antarcticus) and the other known species, are very great, and strongly pronounced, if we regard stature, proportions, character of central tail feathers, changes of plumage, &c. The differences fully warrant the distribution of the species of the subfamily into two genera, which may be thus defined : Buphagus. Bill shorter than the middle toe without the claw ; exceedingly robust ; width at base about equal to the height, which is a third of the length of culmen. Stria? and sulci numerous and well marked. Encroachment of feathers on bill moderate ; and nearly the same on both mandibles. Occiput scarcely crested. Wings only moderately long for this subfamily, the pri- maries very broad, and rounded at their tips. Tail very short, broad, nearly even, the feathers truncated ; central pair projecting but little, and broad to their very tips, which are also truncated. Feet large and stout ; tarsi shorter than the middle toe and claw. Size large ; form robust and heavy ; general organization very powerful. Colors much the same over the whole body ; [May, NATURAL SCIENCES OF PHILADELPHIA. 129 not subject to any great variations with age, sex, or season. Species, B. skua (type) and B. antarcticus. Stercorarius. Bill equal to middle toe without the claw, moderately robust, height at base more than a third of culmen ; striae and sulci fewer and more slightly marked. Encroachment of feathers on bill very great, especially on the upper mandible, where it greatly exceeds that on the lower, and is of a different outline from that of Buphagus. Occiput decidedly subcrested. Wings exceedingly long, the primaries narrow, tapering, with quite acute tips. Tail long ; the lateral feathers more or less graduated ; the central pair considera- bly, sometimes excessively, elongated, tapering and filamentous. Feet rather slender, the tarsi equal to, or slightly longer than the middle toe and claw. Size moderate or small. Form less robust, general organization much less powerful. Nearly bicolor when adult ; passing through very various states of plumage before arriving at maturity. Species, S. pomarinus, parasiticus, (type) Richardsoni, Hardi/i, spinicauda, Buffoni. Of these, the five last are very strictly congeneric in every particular. Pomarinus, by its larger size, somewhat more powerful form, shorter and broader central tail feathers, &c, shows a slight aberration towards Buphagus. But in all other features the essential characters of Stercorarius are so strongly pronounced, that it cannot afford a link by which the two genera may be united. ?

Having a very extensive series at command, I have endeavored to trace one stage from another, and point out 1863.] 10 130 PROCEEDINGS OP THE ACADEMY OP exactly how the great changes of plumage to which the hird is subject, are produced. Adult. Bill horn, deepening into black ; feet black. Pileum and occipital crest brownish-black ; this color extending much below the eyes, and occupy- ing the feathers on the ramus of the inferior maxilla. Acuminate feathers of the neck light yellow. Back, wings, tail, upper wing coverts, under tail coverts as far as the flanks, deep blackish-brown. Under parts, from chin to abdomen, and neck all round, (except the yellow acuminate feathers,) pure white. The above is the plumage of the fully adult bird, and is comparatively not often met with. A more usual state of plumage (described by Lawrence and figured by Audubon* as " fully adult, : ') is as follows : Nearly adult. Generally as in the preceding, but with a row of brown spots across the breast ; the sides under the wings transversely barred with white and brown ; the purity of the dark color of the abdomen interrupted by some touches of white. The legs still wholly black, and the tail feathers projecting as much as in the fully adult. Now, as a somewhat younger stage than the preceding, we have the fol- lowing Intermediate stage, (No. 1275.) The band of dark spots across the breast has widened and enlarged, so that the whole breast appears brown, mottled with white ; the sides under the wings are conspicuously barred with white and brown ; the white of the under parts is continued down over the abdomen to the under tail coverts ; the pure brown of these parts which obtains in the adult, now only appearing as transverse bars among the white. The upper tail coverts and some of the wing coverts are barred with white. The bases of the primaries are inferiorly white. The central tail feathers now only project an inch. The tarsi are quite changed in color ; they are now irregularly blotched with chrome yellow, the hind toe and nail being of this color. The above changes are very gradual, and readily identifiable ; the quo modo of their production may be thus summed up : In the adult the white and brown occupy distinct and well-marked regions ; and the two colors are separated by trenchant lines of division. The younger the bird, the more this distinctness of definition of colors is lost, the white invading and barring the brown, and the brown invading and mottling the white, wherever the two join. Then also the feet lose their black, and are variegated with yellow. Besides the above, we find a state characterizable thus : Dusky stage. The bird is very nearly unicolor : blackish-brown all over; this color deepening into quite black on the pileum ; lightening into fuliginous brown on the abdomen, with a slight gilding of the black on the sides of the neck. The whitish bases of the primaries exist. The feet are in the chromo- variegated condition. The central tail feathers scarcely project half an inch. In the last edition of the Manuel d'Ornithologie, Temminck corrects various errors committed in previous editions, and gives, as his mature opinion, four " varieties" of this species. By examining his diagnoses, it will be seen at a glance that his "variety C" is the fully adult plumage above characterized ; of which he says truly that it is " assez rare." His " B " is our second stage ; his " A " is about our third stage ; while his " D " is the fusco-unicolor stage just given. In his earlier editions he maintains that this dusky stage is% absolutely independent of sex ; but latterly he says that it is possible that the dusky birds are females ; the white-bellied ones males. Ornithologists main- tain very diverse views on this subject ; but I believe it is generally supposed that this state of plumage is not indicative of either sex, but simply of imma- turity. Now I think that the four' plumages which Temminck describes as adults * I have Audubon's original specimen before me. It agrees minutely with his plate; ami is also the specimen from which Lawrence's description in the General Report was taken. [May, NATURAL SCIENCES OF PHILADELPHIA. 131 (varieties A, &c. ) are really the progressive stages of the same individuals. I do not think that even the dusky stage constitutes a distinct "variety," (i.e., the birds remaining in that state all through their lives ;) much less the other stages. I am of opinion that every Jiiger, before arriving at full maturity, passes through each of these states : beginning with a rufo-rayed plumage to be presently described passing from that next into the dusky ; and then assuming successively the other stages above characterized. The only ques- tion is this : What age, sex, or season is this dusky stage characteristic of 1 I think that it comes in next after the very young rufo-rayed plumage, for this reason. We find these dusky birds to be generally less robust than the others; with weaker bills, less elongated central tail feathers, and parti- colored tarsi. Now it is well known, that the younger the bird, the smaller it is, the shorter are the central tail feathers, and the more yellow the tarsi. Another argument, by analogy, is that the S. parasiticus is found in exactly the same unicolor state ; and from a great number of species it can be proved, I think, that in that species it supervenes directly from the rufo-rayed plu- mage. [See remarks under L. parasitica.'} The following is the plumage of birds of the year : Young of Year. Bill much smaller and weaker than in the adult, light colored to beyond the nostrils, when it becomes brownish-black. Feet and toes mostly bright yellow, the terminal portions of the latter black. The whole body is everywhere transversely waved with dull rufous. On the head, neck and under parts this rufous forms the predominating color; and the bands are exceedingly numerous, of about the same width as the intervening dark color. On the flanks and under tail coverts the bars become wider, and almost white in color. On the back and wing coverts the brownish black is the predominating color ; and if any rufous is present, it is merely as a nar- row edging to the feathers. The under wing coverts have irregularly-angular transverse waves of brownish black and white. The remiges and rectrices are brownish black, darker at their tips ; fading into whitish towards the bases of their inner vanes. On the head and neck the light rufous decidedly predomi- nates, and seems indistinctly but thickly nebulated with dusky ; this dusky forming a conspicuous spot just at the anterior canthus of the eye. (In this plumage the bird is the Stercorarius striatus of Brisson and the Larus crepi- datus of Gmelin and Latham.) There can be no doubt that the Stercorarius striatus of Brisson. and the Larus crepidatus of Gmelin and Latham, refer to this species in the very im- mature state of plumage just described ; when the bird is considerably smaller than when adult, and is wholly rayed with rufous and dusky, with white spaces at the bases of the wing and tail feathers. The Stercorarius crepidatus of Vieillot, (1817,) however, is the true parasitica, as is also the Lestris crepidata, of Degland, 1838, and of Schinz, 18-10. The Lestris crepi- data of Brehm (1823) is the young of the Buffoni. (Vide synonyms of these species.) Latham in his Index, page 819, gives a "Larus crepidatus var. /?," which is of course also to be referred to the young pomarinus. The Larus parasiticus of Meyer and Wolf is, I believe, the only instance of the application of that specific name to this species. The other synonyms of the species do not require any special notice, as they are quite plain and uncomplicated. By most authors the Catharacta cepphus of Briinnich is considered as refer- ring to the long-tailed species. I must confess, however, that I can hardly discover grounds for &uch an identification of this name ; and am rather inclined to the opinion that his cepphus is based upon the young pomarinus ; as are the crepidata of Gmelin and Latham, and the striatus of Brisson. Let us look at the description for a moment. It is evident, from almost every paragraph of it, that he had in view a young bird of the year, in the state 1863.] 132 PROCEEDINGS OF THE ACADEMY OF when they are transversely rayed with dusky and rufous, paler on the ab- domen, and have the bases of the quills and rectrices white. The only point is to determine of what species it is the young. Regarding its size, Briinnich compares it with his Catharacta skua, saying, that it is much smaller than that species, and " Magnitudo parasitica^.' " The young of the year of poma- rinus is more nearly of the size of an adult of parasitica, than is the young of the year of the long-tailed species. The description of the colors, form, &c, which follows, agrees precisely with those of the young pomarinus; and when we remember that at that date the differences between the common and long-tailed Jiigers were not recognized, the two species being confounded together by authors generally, (except Brisson ;) it does not appear by any means certain that Briinnich had the long-tailed species in view in drawing up the description of lt cepphus." Had that been the case, he would pro- bably have compared it with parasitica rather than with skua. Moreover, Latham, in his description of his Larus crepidatus, which is the young poma- rinus, gives " cepphus, Briinn." as a synonym of that species. Upon the whole, therefore, while I by no means insist upon the reference of the name under consideration to the pomarinus, I merely wish to show that it very possibly belongs to it : and that [the description is too vague and uncertain to justify the use of the name for either of the species. It is for this reason that I have adopted Boie's name " Buffo i" for the long-tailed Jager. Having always professed a rigid adherence to the great law of priority in questions of nomenclature, I am, perhaps, in the present instance, rendering myself liable to be taken to task for not employing the name " crepidatus" of Gmelin and Latham (1788-90) for this species instead of pomarinus of Temminck, since the former name is in all probability based upon this species. The description is, however, short and unsatisfactory, and is, moreover, based upon the young bird of the year ; and, though there cannot really be much doubt as to the species which these authors had in their minds in preparing their descriptions, still I think in view of the above considerations, that it will hardly be expedient to supersede so definite, long- known and universally employed a name as pomarinus. At the same time, should any one else see fit to do so, I would in future writings unhesitatingly follow his example. 4. Stercorarius parasiticus Gray ex Briinn. ?

I have, however, placed them under the head of parasitica, for this reason: Retzius in his edition of the Fauna Suecica (of 1800) gives them as synonyms of his jyarasitica, of which his description is, " Rectrices 6, 6, (i.e., the central pair) caeteris 4 poll, longiores;" thus clearly referring to the true parasitica. Descriptions of previous authors had mostly been merely " Rectricibus mediis longissimis," whence the uncer- tainty. Retzius, however, is in error in adducing Stercorarius longicaudatus, Briss., as a synonym of parasitica.

Pursuing the question of the general "theory of variation" in this genus, it may be well to examine closely the various stages of this its typical spe- cies. The exceedingly rich series in the Smithsonian collection enables me to trace it through all its variations. Young of the Year in August. Size considerably less than that of the adult, form every way more delicate. Wings more than an inch shorter ; bill and feet much slenderer and weaker. Bill in some specimens light bluish horn, in others greenish olive, the terminal portion brownish black. Tarsi and greater part of the toes yellow. The bird is every where rayed and barred with rufous and brownish black. On the head and neck the rufous is of a very light ochraceous tinge, and is by far the predominating color ; the dark only appearing as a delicate line along the shaft of each feather. There is an aggregation of the brown into a spot at the anterior canthus of the eye. Proceeding down the neck to the back, the longitudinal lines become larger, and gradually spread wider and wider, until between the shoulders they occupy the whole of each feather, except a narrow border of rufous ; which latter is of a deeper tint than on the head. Passing down the throat to the breast, the rufous becomes decidedly lighter, almost whitish, while the brown, which on the throat exists only as a light longitudinal line, change s on each feather to transverse bars of about equal width with the light rufou s bars with which it alternates. This pattern prevails over the whole unde r * This is a combination of parasitica and Buffoni, as shown by the description and indescrimi- nate citation of synonyms. This error Temminck corrects in his edition of 1S40, (pp. 493, 499, 500,) where he recognizes the two species and describes them accurately: but unfortunately tall*) the parasitica, " Jiichardsoni," and the Buffoni, " parasitica." 1863.] 134 PROCEEDINGS OF THE ACADEMY OF parts, the transverse bands being broadest on the flanks and under tail and wing coverts, narrowest in the middle of the belly. The primaries are brownish black, narrowly tipped with rufous, their shafts yellowish, their inner webs fading basally into white. The tail has the same coloration as the wings. The central feathers project about three-fourths of an inch. As the bird above described grows older, the bill and feet become stouter, the cere better developed ; while the rufous everywhere gives way to the darker color. No special stage can be characterized, however, until the rufous is far outweighed by the dusky. Then we have (No. 18652). Size and general proportions nearly those of the adult. Bill and cere perfectly formed ; feet mostly black, but with some yellow blotches. The upper parts are unadulterated with any rufous bars ; the deep brownish - black pileum has appeared, and the sides of the neck have obtained their yellow nuance, which contrasts conspicuously with the fuliginous background. Evidences of immaturity, however, are found on the under parts, where the dark color is mixed with illy-defined transverse bars of ochraceous. Rufous is also found at the bend of the wing, and on the under wing and tail coverts. The primaries are still whitish baso-externally, as are also the rectrices. The central rectrices project 2^ inches, and have the tapering form of those of the adults. By the disappearance of the little rufous mentioned above, we have arrived at a very marked and decided stage, viz : (No. 20362). With the size and proportions of the adult. Wholly deep dusky ; darker and more plumbeous superiorly ; lighter, and with a fuliginous tinge inferiorly ; the pileum quite black ; the latero-nuchal yellow, well pronounced ; the remiges and rectrices quite black ; feet black. Having reached this perfect dusky stage, we will go back again to the young plumage first characterized, and show how specimens occasionally seem to proceed at once towards the adult condition with the white under parts. For example (No. 2754). The juvenility of the specimen is attested by its small size, delicate bill and feet, little projection of the central rectrices, general molli- pilose condition of plumage, &c. The rufous of the very young bird, instead of giving way everywhere to dusky, yields to this color only on the upper parts and crown ; on the sides of the head, neck, and the whole under parts, whitish being the predominating color. the continuity of this last being interrupted by indistinctly marked dusky bars. The yellow of the sides of the neck has not yet appeared. There is the same white space on the bases of the wings and tail as exists on the very young. The central tail feathers only project about li inches. By an attentive consideration of the preceding facts, it will be evident that we have found the same very young plumage to change gradually through one series of specimens into the fusco-unicolor state ; through another serie3 into a stage which tends to pass directly into the normal plumage of the fully adult bird, without going through this dusky epoch. What can we deduce from this perplexing fact? Does one a assume this dusky plumage at a- certain age, and the other not? Does this dusky state constitute the normal adult plumage of one sex ? Is it a seasonal feature, which both sexes return to at certain periods in each year? or, finally, does it constitute a purely accidental, but constant variety? Authors of weight are divided on each of these points. I reject entirely the last hypothesis, viz : that some birds attain to this dusky stage and retain it during their lives, though they may have sprung from normally colored parents, and have normally colored progeny. What- ever age or season, or whichever sex this state of plumage indicates, I think there can be no reasonable doubt that it is a normal and constant stage which every individual of one (or both?) sexes 'passes through or attains to, in its [May, NATURAL SCIENCES OF PHILADELPHIA. 135 progress towards maturity. The only question 13, what age is to be assigned to this dusky state, and whether one or both sexes participate in it. Leaving now speculation for facts, we have yet to notice the mature bird. Taking either the dusky state (No. 20302,) or No. 2754, we find that both tend to produce the following plumage : Nearly mature, (No. 20144.) Size and form of the adult. Pileum and latero-nuchal region, and whole upper parts, as in the adult. The under parts white (as in the adult), but clouded everywhere with dusky patches, most marked across the breast, on the sides, the flanks, and under tail coverts, and lea.ving the middle of the belly and throat nearly pure. Varying degrees of this dusky nubilation approach in some specimens nearly to the uniform dusky above characterized ; in others fade almost into the pure white of the adult, connecting the two ages perfectly and uninterruptedly. The tarsi of those specimens most dusky have small yellow blotches ; the others not. Now, by the complete obliteration of these dusky cloudings on the throat, breast and belly, and its increased intensity on the under tail coverts and abdomen as far as the flanks, we arrive at last at the Adult, perfect plumage, (No. 16802). Bill a little shorter than the head or tarsus, about equal to middle toe without the claw; stout, about as high as broad at the base. Cere longer than the nail. Culmen broad and flattened, with a longitudinal groove on each side. Nostrils as in the other species. Curvature of culmen and tomia very gradual. Gonys short, about straight ; rami very long, a little concave ; eminentia symphysis little marked. Strias and sulci as in the other species. Tarsi about as long as the middle toe and claw, moderately stout, somewhat roughened supero-posteriorly, but not nearly as much so as in pomarinus. Scutellation and reticulation of tarsi, toes, and interdigital membranes as in the other species. Tail moderately long, slightly graduated, the lateral feathers broad quite to their apices, which are somewhat truncated, the shaft slightly protruding as a small mucro ; the central pair projecting three to four inches ; rigid ; not losing much of their breadth until about four inches from their ends, when they commence to converge regularly to a quite acute apex. They have nothing of the filamentous char- acter of those of Buffoni. Wings long, powerful, their rhachides rigid, their apices somewhat acute. Pileum, occipital crest, whole upper parts, deep brownish black, with a somewhat slaty tinge, and a slight but appreciable metallic nuance; this color deepening into quite black on the wings and tail. Rhachides of primaries and rectrices whitish, except at their tips ; the inner vanes albescent baso-internally. Chin, throat, sides of head, neck all round and under parts to the vent, pure white ; the feathers of the latero-nuchal region rigid, acuminate, with disconnected fibrillar, light yellow. Under tail coverts like the upper parts, but somewhat of a fuliginous tint ; the line of demarcation from the white of the abdomen very trenchant. Dimensions of fully adult. Bill above 1-40 inches ; height or width at base, about -50. Wing, from flexure, 13-00 : tarsus, or middle toe and claw, 1-80 ; tail 5J, its centre feathers nearly 9-00. Dimensions of young of year.

The changes of plumage of this species are strictly homologous with those of S. parasiticus ; and it is therefore quite unnecessary to present them in this connexion. As before remarked under head of parasitica, it is exceedingly difficult, if not quite impossible, to determine positively to what species the u parasitica" and ' cepphus" of the older authors refer. This confusion is occasioned partly by the brief and vague diagnoses given, and partly by the fact that the two species were really confounded by authors (except Brisson) until com- paratively quite a late period. Even so late as 1820 Temminck does not separate the two : his description applies to either, and the synonyms of both are indiscriminately adduced. From which state of things it results that nearly all the older names and citations may be without difficulty referred to either species. This in effect has been really done ; some authors, for ex- ample, considering Brunnich's or Linnaeus' parasitica to be the long-tailed species, and others holding a contrary opinion, until the identification of these names has become almost a matter of choice, or rather of tacit agree- ment among ornithologists. This is the more to be regretted since on it de- pends the question whether the common or the long-tailed Jager is to be called parasiticus. A glance at the synonymy of the species will show that authors have been about equally divided on these points. Before the introduction of 11 Richardson?' by Swainson, the common Jager was usually called "para- sitica;" but after the adoption of this name " Richardson? 1 by Temminck, for the common Jager, the name parasitica was for some years almost univer- sally applied to the long-tailed species. In the year 1819, or thereabouts, the name of Buffoni was proposed by Boie for the long-tailed species, and was adopted by many writers ; while others had recourse to Brisson's old name " longicaudatus." Within the last few years, however, the name "para- sitica" has again reverted to the common Jager, while the other species has been usually called " cepphus" after Brunnich. This identification of Brun- nich's name is adopted by Gray, Bonaparte, and other writers. Our reasons for rather referring it to the Stercorarius pomarinus will be found under the head of the latter. Granting, as it is undoubtedly wisest to do, that th.z parasitica of Brilnnich, Linnaeus and Gmelin, is really the common short-tailed^ Jager, it still remains an open question to which species we are to refer the Larus parasiticus of Latham. I incline to the opinion that it is based upon the long-tailed spe- cies, for the following reason : Although the diagnosis is brief and unsatis- 1863.] 138 PROCEEDINGS OP THE ACADEMY OP factory, and although the synonyms of the two species are indiscriminately adduced, (thus, e.g., Lotus parasitica, Linn, and Catharaela parasitica, Brunn., with Stercorarius longicaudatus, Briss., &c.,) yet in his further description he says of it, " 21 pollices longus." The common Jager never attains to this dimension. Latham commits the error of giving Stercorarius longicaudatus, Briss., as the male," and Stercorarius , Briss., (without a specific name,) as the female of his species ; whereas, these two citatio* really refer to the two distinct species. The specific name " longicaudata , ' > of Brisson (1760) being untenable for obvious reasons, " cepphus" of Brunnich (1764) being too indefinite to warrant its employment, "parasitica" of Brunnich (1764) being used for the common Jager, the first definite distinctive name for the long-tailed species appears to be " Buffoni" of Boie, (1819.) This specific appellation we accordingly adopt. Note. The present paper completes a series of brief reviews of the three most important of the four subfamilies of the Laridae, viz. : the La- rinse, Sterninag and Lestridinae. In conducting an investigation into the characters and the bibliography of these groups, with special reference to North American forms, it has been thought expedient to issue in advance a brief prodromus, so to speak, of each subfamily as soon as its examination was completed. Combining the results arrived at in the investigation of each of these groups, and making whatever additions or modifications future re- search may dictate, the writer hopes before long to present a more complete and elaborate Monograph of the North American forms of the Laridae. It is contemplated to present the anatomical as well as the external characters, both of the higher groups and of the more marked species ; the changes of plumage, dependent upon either age, season, sex, or pure accident, which examination of very extensive series may show ; together with the biblio- graphy of each species, and a discussion of doubtful points of nomencla- ture and relationship. The Monograph will be illustrated by colored plates of the bills, wings, feet, &c. of most of the species, showing exactly wherein one differs from another ; and no pains will be spared to render it a complete exposition of the present state of our knowledge of this family of birds. Synopsis of the MARINE INVERTEBRATA collected by the late Arctic Expedition, under Dr. 1. 1. Hayes. BY WM. STIMPSON, M. D. The collections of Dr. Hayes, as might be expected from the thorough search to which the Arctic regions have lately been subjected, and the characteristic paucity of forms existing there, embrace few novelties. They possess, however, great interest, from having been found in great part at localities much nearer the Pole thau any previous expeditions have succeeded in reaching on the American side of the Arctic circle. They include some species hitherto found only on the European side. And, we may add, the number of species collected by Dr. Hayes is greater thau that brought back by any siDgle ex- pedition which has yet visited those seas, as far as can be judged by published accounts. Of the localities mentioned below, Port Foulke and Littleton L. are on the eastern or Greenland shore of Smith's Straits, in lat. 78. Cape Faraday is on the west shore of the same Straits, in lat. 79 45'. Godhavn is at the southern end of Disco Island, in lat. 69 nearly. [May, NATURAL SCIENCES OF PHILADELPHIA. 139 CRUSTACEA. 1.

The upper pair of uropoda or caudal stylets is shorter than the other two pairs. Length nearly one inch. Littleton Island. 13 Gammarus locusta J. C. Fabr., Ent. Syst. ii., 516. Kroyer, Groenl.
