CEPHALOON Newman. Ent. Mag., Vol. v. Body slender: the breadth to the length as one to five: elytra tapering posteriorly, length exceeding three times the width at base : scutel triangular, with the apex rounded : prothorax pyramidal, longer than wide, base rectilinear, scarcely as wide as the elytra, sides rapidly converging to a narrow apex one-third the width of the base : head small, depressed, elongate and protracted, contracted from the eyes anteriorly and posteriorly to the incisure formed by its attachment : eyes lateral and vertical, emarginate anteriorly for the reception of the antenne: antennz short, scarcely extending beyond the humerus, slightly thickened towards the apex: first and second articulations obconic, the latter very short, the third cylindric and as long as the fourth and fifth, which, with the remainder, are subequal and obconic, except the eleventh, which is lengthened ovate : the four terminal articulations are manifestly thicker than the antecedent ones : labrum large, transverse, and rounded before, where it is clothed with hairs: mandibles strong, incurved and acute: maxille slender and porrect, the apex clothed with twisted hairs: maxillary palpi with the apical articulation securiform, the penult short obconic,and the preceding one cylindric: labial palpi 2-articulate, apex obconic : feet long and slender, medial and posterior tibie with two terminal spines, tarsi simple, heteromerous, ungues finely pectinate, pulvilli oval. C. tepturoweEs Newm. Ent. Mag.

Finely pubescent, cinereo-fuscous, head and prothorax varying to fulvous ; antenne and feet of the latter colour, apex of the posterior femora and tibie * The mark | (an inverted f) is here proposed to be placed between the name and the authority when a species has not been characterized, the reversed mark indicating the impropriety of such a practice. In synonymy, a recent name sometimes takes precedence of an earlier one, and it is often inconvenient, particularly in catalogues, to give the reason. When a name has been previously used, let it be denoted by |l, the double line indicating that there are two supposed distinct species under this name, as—Cicindela hentzii Dej. = C. hemorrhoidalis || Hentz, the latter having priority in date, but with a name previously in use. When an author cites erroneously, the mark { may be used, as—Aphodius fimetarius{Latr., which is not the true A. fimetarius Lin. (Scarabeus.) The practice, in lists of synonyms, of citing a different authority for each work is wrong, as in Lucanus cervus Lin., L. cervus Latr. R. An. etc., because Latreille describes the species as that of Linneus. In the case of the molluse Infundibulum trochiformis Lam. (Calyptrea): I. trochiformis Lea; the latter citation is correct, as it is here inadyertently described as a new species under a preoccupied name. As many cite, a synonym like this will not a us whether the citation refers to a supposed new species, (as in this case) or to the placing of the species under a different genus from that in which it was first placed.

Total length (of skin) from tip of bill to end of tail, two feet six inches, of which the tail alone measures seventeen inches. Hab. Western Africa. The specimen above described, I received several years since from Robert MacDowell, M. D., surgeon, attached to the colonial government of Sierra Leone, an enthusiastic naturalist, who obtained‘it on the banks of St. Paul’s river. This species resembles no other which I have seen, or of which I can find a description, and may at once be recognized by its white erect crest and long tail. From the same gentleman I have received several other specimens of this genus, also, from Western Africa, one of which is the Buceros elatus, Temm., of which a figure of the head and bill is given in PI. Col., 521, and another, perhaps the female of the same species; as such, however, 1 do not feel warranted in describing it at present, the bills of the two specimens differing more materially than I have been accustomed to see in the same species. Two crania of the Buceros elatus are in the collection of Dr. Morton, one of which is undoubtedly from Western Africa. As this species appears to be known only from the figure of the cranium and beak above alluded to, I take the liberty of giving a description of the specimen which I suppose to be a male. 35 136 MR.

This species resembles no other which I have met with, and may readily be recognized by its conspicuous and peculiar white bar on the wing, formed by large white spots at the tips of the greater coverts. Upon examination it will be found that these spots are on the outer webs only. I have seen one specimen only of this species, which belonged to the Rivoli collection.

Resembles Icterus cucullatus, Swainson, more than any other species known to me, but I. cucullatus is very conspicuously marked with white on the wings, which is not the case in the species now described. The I. cucullatus has black shoulders, its bill also is longer and more slender, and in other respects is entirely different. After a careful examination, with the advantage of the Academy’s large collection of Icteri, I am rather surprised that I can find no description which will apply to this species, although I have seen it occasionally in collections for the last ten years. Of the four specimens now in the collection of the Academy, two from the Rivoli collection are labelled Mexico, one also from that collection is without label of any kind, and the fourth was received by me from Brazil. I have also seen specimens said to be from the island of Trinidad. PLSb72 I. crraupu, nobis.—Adultus.

Resembles Icterus Xanthornus, (Linn.) more than any other species with which I am acquainted or have found described, but is larger, and has the mask much broader. In I. Xanthornus, the gular black scarcely exceeds the width of the under mandible, but in the species now described, it fully includes the eyes and the whole base of the bill. J.

XII.—Monograph of the Fossil Squalide of the United States. By Roperr W. Gisszs, M. D., of South Carolina. Correspondent of the Academy of Natural Sciences, &c. “¢ When Cuvier closed his researches in this department, he had named and described for the guidance of the geologist, ninety-two distinct species of fossil-fish ; nor was it then known that the entire geological scale, from the Upper Tertiary to the Grauwacke inclusive, contained more. Agassiz commenced his labours, and in a period of time little exceeding fourteen years, he has raised the number of species to sixteen hundred. And this number, great as it is, is receiving accessions almost every day.”—The Old Red Sandstone, by Hugh Miller. ‘‘ Grandiaque effossis mirabitur ossa sepulchris.”—Virgil, 1. Georgic. 493. My collection of fossils is rich in the teeth of Squalide, from the Tertiary beds of South Carolina. I say rich, in comparison with the meagreness of the public museums and private cabinets with which I am acquainted. With the aid of the admirable work of Proressor Agassiz, “ Sur les poissons fossiles,” I have been able to identify many of them; and finding several new forms, I have concluded to attempt their classification and description. Following the minute distinctions of that eminent observer, | had extended my list largely with new species, when a favourable opportunity occurred of submitting my specimens to his inspection. With the candor of a conscientious lover of true science, and the kindness and liberality of a mind free from all selfish consideration, he informed me that many of his species had been described from single specimens and the observation of others— that farther knowledge has induced him to reject several species and to unite others— and that he had formerly considered as forming distinctions, characters not sufficiently fixed to constitute uniform differences. In the present effort for the advancement of American Paleontology, it becomes me at the threshold to acknowledge the essential aid of the labours of this eminent naturalist, to whom I am indebted for the ability to arrange this synopsis. With his acknowledgement, “mais c’est aussi la partie la plus difficile de l’Icthyologie, celle sur laquelle, de Vaveu méme de tous les naturalistes, l’on posséde le moins de renseigmens précis, celle enfin qui, avec le temps, devra recevoir les additions les plus considerables,”—I trust that others may be induced to extend what [have commenced. With the 36 140 DR. GIBBES’ MONOGRAPH OF THE exception of the figures published by Dr. Morton,* and a few by Dr. Haran,t no attention has been given by American naturalists to the fossil Squakde. In the publications on Tertiary Geology, by Conran, Vanuxem, Lea, Rocers, Hones, &c., they are merely noticed as occurring, but no attempt has been made to arrange or describe them. In some of the early works on Fossils, we find notices of the teeth of Squakde under the names of Bufonites and Gilosso-petre,t and in Sir Joun Hiu’s “ History oF Fossiis,” (London, 1748,) are some very good figures of species easily recognized in our collections. His general description being condensed, I take from it the following graphic and comprehensive though poetical paragraph : “In shape they are usually somewhat approaching triangular, and some simple, others tricuspidate or having a smaller point on each side the large one ; some of them are very long, others shorter, and some very broad in proportion to their length ; others as remarkably slender, and narrow ; many also of them are quite straight, but they are not unfrequently met with crooked, and are bent in all the different directions, some inward, some outward, and some sideways, either to the right or left. Many of them have their edges plain, others are serrated more or less deeply, and some of them are undulated or shaped like the figure of a flaming sword at their extremities, and more slightly serrated besides; they are of as various sizes as figures, the larger oues being found of between four and five inches long, and the smaller of less than a quarter of aninch. They are found of vast numbers in Germany, but no where so common as in the island of Malta.” Malta seems even in our time to be the prolific source of these fossils, as M. Acassiz mentions the frequency of specimens in various European collections marked from this locality. In attempting to trace the history of fossil Squalde, I find little to refer to that M. Acassiz has not given, and I am forced again to acknowledge, as Dr. MANTELL has emphatically done in his “ Mrpaus or Creation,” as to fossil Fishes, that to his great work am I indebted for a large portion of my text. ) Formerly the character of the skeleton, whether osseous or cartilaginous, and the number and position of the fins, were the bases of classification of Fishes, but the observation and experience of the distinguished naturalist I have named, have caused him to arrange them by the form and structure of the scales. His division into orders has been continued into genera, founded on his own and the microscopic researches * Synopsis of Organic Remains, &c. t Medical and Physical Researches. {Scilla was the first who detected as the teeth of sharks the supposed Glosso-petre (petrified tongues of serpents). Eyen at this day I have had them sent to me as petrified birds-tongues. i: Oe eae FOSSIL SQUALIDZ OF THE UNITED STATES. 141 of Proressor Owen, of London, who has given to the world a splendid result of laborious and scientific study in his OponrocrRapuy.* The family of Squakde, which it is proposed here to illustrate, belongs to the first order of Acassiz, denominated Pracoips (from ~0£, a broad plate). The skin is irregularly covered with enamelled plates, sometimes large, but often in the form of small points, forming shagreen in sharks, and tubercles in rays. Of these families no remains are found ina fossil state other than teeth and vertebre ; though an exception should be noticed in the discovery of the mouth of an Hybodus, lately reported by Sir Puitip EeeErron, from the secondary of the Isle of Wight, in which the cartilaginous ale were traceable, and a part of the anterior cranial cavity.t The Squalde constitute a large portion of the fossil remains of Fishes, and are confined to the secondary and tertiary formations. An interesting observation of Agassiz’s is here worthy of notice. “De la comparaison des espéces fossiles avec les espéces vivantes, il résulte un fait bien curieux, conforme a ce que l’étude du developement génétique du régne animal nous apprend de tous les groupes bien étudiés, c’est que les types génériques qui prévalent dans la création actuelle, ou n’ont pas de représentans parmi les fossiles, ou bien sont limités aux terrains tertiares et crétacés; tandis que les genres qui paraissent isolés dans notre époque, comme les genres Mustelus et Cestracion, sont représenté par de nombreux genres analogues dans toute la sérié des terrains secondaires.’’t Notwithstanding the differences we observe in the many forms of teeth of sharks, they all possess one essential character of structure, namely, a base or osseous root, of variable form, fixed in the integument, and a crown or exposed portion projecting into the mouth, covered with a greater or less thickness of enamel, assuming many modifications by which the genera are characterized. These teeth only adhere to the integuments and the covering of the jaw, and possess great mobility. They are usually in rows, of which the anterior having been used fall out and are replaced by others ; and new teeth are constantly forming within to succeed the outer as they are lost. ‘The base of these teeth is large and wide, rounded and hollowed or grooved, but never conical nor terminated in acute points; the root is osseous, more or less compact or spongy, without any inner cavity. The crown is variable in form and size in different genera, and even in different parts of the same jaw. In some which are subulate and more or less triangular and compressed, those in the anterior portion of the jaw are straighter and sharper than those in the posterior parts, which are oblique and obtuse. ‘There are marked differences sometimes in the teeth of the * Odontography : or a Treatise on the Comparative Anatomy of the Teeth; their physiological relations, mode of developement, and microscopic structure ; illustrated by upwards of one hundred and fifty plates.

GIBBES’ MONOGRAPH OF THE upper and lower jaw, being straighter and more acute in one than in the other. When the front teeth are similar to those at the sides, they are usually smaller and more pointed, and at the symphysis in both jaws often there is a small tooth, or several of a peculiar form. The teeth are also characterized by serratures varying in size, and by small lateral denticles, which are not always present in young teeth and do not form specific distinctions, though in adults assist in referring them to species. Professor Agassiz has pointed out a distinction between Carcharias and Carcharodon, in the dentine of the former presenting a hollow cone, while in the latter it is solid, the only character they have in common being their microscopic structure. As the latter genus is one of the most prolific in species and prominent in size and form, I commence the series with it. Genus CARCHARODON, Smith. SPECIES. 1. C. MEGALoDON, Agass. Var.

The general form of the teeth of Carcharodon is that of an isosceles triangle, those in the upper jaw being usually a little larger than in the lower, and not as dissimilar as the upper and lower teeth of Carcharias. At the symphysis they are almost entirely straight; the next have their edges sloping, and the last are almost without the middle cone. Inthe lower jaw they are pointed and sloped similarly on both edges ; but what distinguishes them particularly from those of the upper jaw, is a very perceptible furrow in the enamel at the base of the crown. The whole circumference of the cutting edges is covered with fine notches, (dentelures) very FOSSIL SQUALID OF THE UNITED STATES. 143 distinct and uniform in the teeth of both jaws. In many fossil species there are lateral denticles on both edges at the base of the cone, which assist in distinguishing species, but are not uniform characters. In the geological distribution of the species of this genus, it is a remarkable fact. that a large number are found fossil, while there is but a single representative in the recent C. Jamia ; and the reverse is the case with Carcharias, which includes numerous recent species, and has but few fossils. AGAssiz mentions only one, and doubts of another. The genus Carcharodon is not found beyond the Tertiary, the oldest remains being found in the calcaire grossiere (Kocene.) In Europe he mentions the Swiss molasse, (Miocene,) as prolific in this genus, while in South Carolina I find the Kocene more largely productive of them. I have received a few from the former localities, while I have them abundantly from the Eocene. I learn from Prorgssor Acassiz that Mr. Tuomey, who has collected Squalide in the Tertiary beds of Virginia, has found more specimens of Carcharodon in the Miocene. 1, C. MEGALopon. Figs. 1 to 9.—The general form is equilateral, the anterior and posterior edges differ somewhat in the upper and lateral teeth, in consequence of the slope and obliquity backwards. ‘The marginal indentations are uniform over the whole contour of the edges. The enamel is thin but strong, and extends to the root on the outer surface, while there is a large triangular space between them on the inner. ‘This space in large and old specimens is rough with longitudinal cracks or superficial fissures. The thickness is very considerable, in which it differs from the European co-species. ‘The inner face is prominent and the outer flat, in some depressed next the edges and elevated in the middle, giving an undulated appearance. ‘The root is very thick, forming one-third or more of the depth of the tooth; it is concave on the lower surface between the basal extremities, which are rounded or flattened and for the most part symmetrical. The osseous structure is dense and compact, and frequently cracked with fissures. The enamel is also usually striated with longitudinal cracks. Fig. 1 isa lower tooth, and fig. 2 an upper lateral one; fig. 4is of the variety C. rectidens, and figs. 5 and 6 of C. subauriculatus, both which Agassiz now refers to this genus; fig. 3 is probably a symphysial tooth; figs. 7 and 8 are young teeth, the last destitute of dentelures and probably from the extreme posterior portions of the jaw ; fig. 9 resembles C. sulcidens, but intermediate specimens prove it to belong to C. megalodon. I have various specimens from the Eocene of South Carolina, and Miocene of Virginia and Maryland. The largest individual measures six and a half inches in height, and five inches across the extremities of the root. Professor Owen in his Odontography (p. 30) says: 37 - 144 DR. GIBBES’ MONOGRAPH OF THE ‘Fossil teeth, precisely corresponding in form with those of the Carcharodon, occur abundantly in the tertiary formations of both the old and new continents; some of these teeth exhibit the extraordinary dimensions of six inches in length, and five inches across the base. If, therefore, the proportions of these extinct Carcharodons corresponded with those of the existing species, they must have equalled the great mamumiferous whales in size ; and, combining with the organization of the shark its bold and insatiable character, they must have constituted the most terrific and irresistible of the predaceous monsters of the ancient deep.” “In the United Service Museum there are preserved the jaws of a Carcharodon, of which the upper one measures four feet and the lower one three feet eight inches, following the curvature. The length of the largest tooth is two inches, the breadth of its base one inch nine lines: the total length of the shark was thirty-seven feet.” Mr. CHARLEsworTH has given a good figure of C. megalodon in the Magazine of Natural History, (Vol. i. 1834,) and considers it from the Mzocene, and Acassiz views it as proper to the Medial Tertiary. In the United States we must consider it as common to both. There are several fine specimens in the Museum of the Medical College of the State of South Carolina, at Charleston, from the Mocene, and others in the Academy of Natural Sciences of Philadelphia, but their locality is not given. Professor Hitchcock, in his “‘ Geology of Massachusetts,” p. 431, has given a figure of a tooth from the Eocene of Gay’s Head, which is probably C. megalodon. In my autograph collection of distinguished men, I have the originals of the following letters, indicating that in 1806 Dr. William Reid, of Charleston, had forwarded to Mr. Jefferson specimens of C. megalodon, from the Hocene beds of Cooper river. Iam indebted to J. Harleston Reid, Esq., for the specimens and the letters : ‘“‘ CHARLESTON, S. C., FeBruary 11th, 1806. “« S¢r,—Observing you attentive to Natural Philosophy as well as to other branches of science, I take occasion to present you with a fossil, which you may consider a curiosity, and not unworthy of your contemplation. It was found on Ricehope Estate on Cooper river, in forming a canal twenty feet under the surface of the earth, and ten feet above the level of the river swamp. It lay with several others of similar form, in a stratum of earth resembling decayed sea shells, two hundred feet distant from the swamp. I likewise send you a broken one, lest your Excellency should choose to direct a chemical analysis on it. From my experiments, they prove dentous. The curious here have concluded these fossils to be the teeth of some monster unknown at this day. ‘“Tremain with all due respect and the highest consideration, your Excellency’s very humble servant, WIiaM REID.” Tuomas JEFFERSON, Esq. FOSSIL SQUALID OF THE UNITED STATES. 145 “Th: Jefferson presents his thanks to dr. Reid for the curious fossil teeth he has been so kind as to forward to him, and which have been safely received. he will immediately send them to the Philosophical Society at Philadelphia, which is the best disposition he can make of them for obtaining satisfactory enquiry into their character and origin. he prays dr. Read to accept his salutations and assurances of respect. Washington, Feb. 23, 06.” 2. C. ANGUSTIDENS, Agassiz. Figs. 10 to 38. Proressor Acassiz has decided to refer to this species several which he has described by other names, and among them C. lanceolatus, C. heterodon, C. megalotis, C. auriculatus, C. turgidus, C. semi-serratus, and C. tolapicus. At the time his descriptions were given he had seen but few Specimens, and rather hastily decided upon characters which subsequent experience and the examination of many specimens induce him to refer to one species. My collection contains a very full series of individuals of many varieties of form of C. angustidens. Figures are given of them all. While C. megalodon is broad and flat, this species is more lanciform and narrower—the former is destitute of lateral winglets while this is characterized by them well developed on both sides—in some specimens distinctly separate from the principal cone, while in others placed on the same base, the enamel being continuous over both at the radicle. In nearly all the individuals the crown is perpendicular, occasionally tending slightly inwards but oftener outwards. The bodies are arched on the inner surface, flat outwardly, and are covered with a dense firm enamel, usually preserving a beautiful polish, the apex is more or less acute and the edges indented with well marked serratures, which in the winglets are so prominent as to make them appear often as if separated into several. In the larger specimens the root is thick and prominent on the inner face and somewhat concave on the outer, its branches are generally symmetrical. In old teeth there is an interspace void of enamel next the root on the inner face, while on the outer the enamel extends to the root. Figs. 10, 11, 12, represent what Agassiz described as C. angustidens; figs. 13, 14, 15, 16, C. turgidus ; figs. 17, 18, C. tohapicus ; figs. 19, 20, 21, 22, 23, C. lanceolatus; figs. 24, 25, 26, 27, 28, 29, C. megalotis ; figs. 30, 31, 32, C. heterodon ; figs. 33, 34, 35, 36, are lateral teeth resembling C. semi-serratus ; figs. 37 and 38, are probably lateral teeth of an old individual from their greater thickness, and of the variety C. heterodon. Most of my specimens are from the Hocene of South Carolina. Fig. 12 is from the White limestone (Kocene) of Alabama, and fig. 13 from the same deposit in Wayne county, Mississippi. For these specimens I am indebted to C. 8S. Hale, Esq., of Mobile. The largest variety in my cabinet is from the Hocene Green sand of Santee, 146 DR. GIBBES’ MONOGRAPH OF THE South Carolina, the locality whence I procured the bones of Basilosaurus, Dorudon, Pristis Agassizi, Crocodilus macrorynchus, §¢. Fig. 14 belongs to the Medical College of South Carolina, and is from the bank of Ashley river (Kocene.) Fig. 15 is from the marl of Ashley river, and was presented to me by Dr. William G. Ramsay, of Charleston. 3. C. acuripENs, Gibbes. Figs. 39 to 44—I published this new species in the Proceedings of the Academy of September last, from which I take the description : This beautiful species resembles C. angustidens, Agassiz, but is very acutely pointed. Of four specimens which are in my cabinet, the largest cone (fig. 39) measures three inches, and it is more than three times the depth of the root, which is concave, very thick and prominent on the inner face. The body of the tooth, or enamelled portion is conical, the lower third swollen, widest next the lateral denticles, which are distinct from it. The inner face is arched, while the outer is nearly flat, though undulated by depressions next the edges, and having a deep furrow longitudinally in the middle near the base of the enamel, which extends to the root. This does not extend as low on the inner face, and is sloped, leaving an interspace next the root. The cutting edges are sharp and finely indented, the serratures very close. Most of my specimens are straight, (figs. 40, 43, 44,) but I have two which are oblique, figs. 39,41. All are from a locality of (Eocene) Santee limestone in Orangeburg district, South Carolina, with the exception of fig. 41, which is from the marl of Cooper river, sent to me by Col. John Harleston, of Elwood. There are several of this species in the cabinet of the Academy, labelled from New Jersey, and I have a cast of a fine one found in New Jersey, by Mr. C. Barclay, of Troy, New York. 4. C. Morton, Gzbbes. I have only two specimens, both broken. That which is figured, (fig. 45) and of which a cast is in the collection of the Academy, was probably four inches deep and three inches across the root; the upper third is wanting. It is somewhat inequilateral, the anterior edge sloped inwards, and the posterior arched, both the outer and inner surfaces are convex and prominent, the latter trebly so. The enamel is thin but strong, cracked in strie parallel to the edges, and as in most other species converging and disappearing towards the apex: it is sloped on the inner face. The cutting edges are finely indented, the dentelures (if I may be allowed to adopt an expressive word from the French) are very small, and more minute near the base of the enamel. Next the edges on both faces is a longitudinal flattening, giving the appearance of undulations. The root is immensely thick, an inch and a half, and constitutes more than half the bulk of the tooth; it is concave, but the extremities being broken, the form cannot be given ; the structure of FOSSIL SQUALIDZ OF THE UNITED STATES. 147 the dentine is not as compact as in C. megalodon. I have named this fine species in honour of the distinguished pioneer of Tertiary Geology in the United States, Dr. Samuel George Morton. This species appears to be rare. I have seen a single specimen in the cabinet of I’. S. Holmes, Esq., of Charleston, and have met with none elsewhere. 5. C. Lancirormis, Gibbes. Figs. 46, 47, 48, 49, 50, 51.—Very flat, acutely pointed, triangular, nearly equilateral ; the posterior edge slightly sloped, while the anterior is straight. The root is not much thicker than the base of the cone, very concave, the rami not symmetrical, one being much longer than the other; in the small lateral teeth this, however, is scarcely perceptible. The edges are sharp and finely indented ; the inner face elevated, the outer plane, in some specimens concave. Viewed laterally some are much bowed or arched forward. In the middle of the outer face near the base of the enamel, is a longitudinal depression, the sides of which are elevated, and unite above the horizontal middle line, and form a ridge to the apex. It has lateral appendages, which are not distinct from the principal cone. The enamel extends lower on the outer face than on the inner. I have a series of specimens from the Eocene beds of Ashley and Copper rivers, South Carolina. 6. C. sULCIDENS, Agassiz. Figs. 52, 53.—These are remarkable for their pointed form and flatness and thinness. They have the form of an isosceles triangle, and are about one-third deeper than long in their bodies. The inner face is a little rounded, the outer is flat, appearing even concave. On the inner face near the base of the enamel there is a series of plaits or folds, which causes grooves or vertical furrows. The root forms a fourth, sometimes a third of the height of the tooth, it is regularly concave and is recognized always by its spongy appearance. ‘The base of the enamel is nearly parallel to the base of the root, at least on the outer face. : I have two large specimens from the Miocene of Darlington, South Carolina, one of which is figured, fig. 52, and several from the Kocene of Orangeburg, South Carolina, of which fig. 53 is the largest.

Allied to Galvezia, but with a prominent palate and a saccate spur at the base of the corolla. - G. SPECIOSA. A bush about three to four feet in height, full of bright scarlet flowers. The older branches covered with a smooth grey bark, all of them cylindric. The younger branches leaves and flowers more or less hairy, with a soft pubescence. Leaves rather small, coriaceous, ternate, verticillate, and apparently evergreen, with a few obscure reticulated vessels, running over the under surface ; their form oblong, rather obtuse, entire and attenuated at the base into a short peduncle: there are no stipules or bractes, though the leaves diminish to a very small size as the terminal inflorescence advances. Length of the leaves about one and a half inches, the breadth about half an inch. Peduncles axillary by threes shorter than the lower leaves. Calyx unequal, 5-parted, the segments linear-lanceolate. Corolla about an inch in length and tubular, with a conspicuous saccate spur at the base ; the border, personate, the lower 3-lobed, lip with a somewhat prominent smooth palate ; upper lip 2-lobed, somewhat erect, and deflected at the sides. Stamens didynamous, arising from the base of the tube, the pairs a little unequal, the filaments with a chaffy down at the base.

NUTTALL’S DESCRIPTIONS OF NEW Though so different in habit yet closely allied to Antirrhinum ; the tubular corolla, smooth palate, and entire stigma, being nearly all that distinguishes it from that genus; the seed may also prove different, but that is at present unknown.

Flowering in the month of February. *CROSSOSOMA.t+ Calyx 5-leaved, imbricated, somewhat coriaceous and persistent, the leaves unequal and concave, with colored margins. Corolla of five subsessile, oval petals. Stamina perigynous, about twenty-five, on a fleshy disk; anthersadnate. Ovaries two to five, united at base into a short stipe, 1-celled ; ovules many, attached to the ventral suture in a single crowded series. Stigmas thick and sessile, recurved. Capsules two to five, coriaceous and cylindric, opening longitudinally and inwards, many-seeded. Seed roundish-reniform, nearly surrounded by a deeply fringed arillus. Embryo not seen.—A Californian shrub, with alternate, entire, crowded, exstipulate leaves, and 1-flowered, short, terminal branchlets; flowers white. C. CALIFORNICA. A tortuous shrub, about four feet high, with a hard whitish wood. The bark light grey and very bitter, while the wood and leaves possess very little taste. Leaves entire, cuneate-oblong, and small, somewhat coriaceous, smooth, apparently evergreen, obtuse, or acutely terminated with a small cartilaginous point; the nervures few and somewhat reticulated : one to one and a half inches long, by about half an inch broad. Flower branchlets, resembling peduncles, about two inches long, with two leaves towards the base. The flower, a white Piony in miniature, and about the size of an apple blossom. The calyx of five concave, somewhat coriaceous, persistent leaves, with white petaloid thin margins. Petals five, white, oval, with short claws, seated as well as the stamens, on the thickened disk of the calyx. Stamina about twenty-five, persistent nearly with the ripening capsules; filaments a little longer than the linear, adnate anther, anthers, 2-celled, opening lengthways. Carpels two, three, four, rarely five, coriaceous. Stigmas thick, sessile, and recurved. Capsules recurved, coriaceous, turgid, united at the base, free above, and divaricate, one-half to three-fourths of an inch in length. Seeds very numerous, pale testaceous, roundish-reniform, smooth and somewhat compressed, so nearly covered with a copious fringed arillus, as to appear almost packed in tow; the cavity of the testa being curved, indicates probably the form of the embryo. After examining many of the seeds, I find the rigid coriaceous testa, in every instance empty, so that the nature and character of the germ remains unknown, and the real affinities of this curious plant are therefore uncertain. It is probably Polygamous dioicus, as the stamens appear destitute of pollen. + From xpoosos fringe, and cua a body ; in allusion to the fimbriate arillus. PLANTS COLLECTED BY DR.

E. tenellum. Nutt. (Non. Torrey.) Proceed. Acad. Nat. Sci., Feb. 1848. Allied to E. ovalifolium, which it resembles at first glance, but with shorter leaves and elongated scapes, the flowers deep brown-purple, and scarcely one-third the size of that species. The capitulum in E. ovalifolium, like the present, is made up of several sessile involucres, which are sometimes nearly smooth, the perianth also is very unequal, three of the outer segments being nearly round-oval, while the inner are oblong. Has. In the Rocky Mountains, on the western slope. The character of the genus Eviogonum, of which there are so many species, perhaps deserves some additional consideration. The genus, as founded on E. tomentosum of Michaux, possesses yet some peculiarities not common to the rest of the genus ; among the rest of its characters I may remark, that in place of the interior segments of the perianth being smaller, it is the reverse ; the perianth increases in size with the perfecting of the fruit, and asin Rwmez, the three inner segments are larger and erect, the three outer reflected; the next discrepancy in the character, as given by authors, is in the condition of the embryo, which is placed in the centre or axis of the seed, and is not as described excentric. In E. longifolium, besides a remarkable difference in habit, the perianth is wholly herbaceous, very lanuginous, and the segments all so very equal, as to appear, at 166 MR. NUTTALL’S DESCRIPTIONS OF NEW length, almost disposed in a simple series; the achenium is also lanuginous, and the seed presents, as in Li. tomentosum, a concentric embryo. For E. longifolium I would therefore propose the name of TracnyrTueEca, excluding every other species. It is the first species of the section Er1antua of Bentham, which name, in not being exclusive, and too near Erianthus, cannot properly be employed for the present plant. It is very peculiar in its solitary leaves and alternate branches. In all the rest of this numerous genus, the outer segments of the perianth, which increase a little in size, are either larger and erect, or all nearly equal. In these, some of which have the embryo excentric and others concentric, the subgeneric name of OLycoconum may be applied, but whether any other subdivision may be made by the condition of the embryo is at present uncertain. In E. flavum I believe the embryo is exceutric, but how far that species connects itself to any others of similar form, rernains to be examined. * BUCYCLA.t+ Perianth membranaceous, coloured, petaloid, dimorphous, the three outer divisions orbicular, concave; the three inner linear-oblong, emarginate, connivent into a cylinder.

Chrysothamnus, by Torrey and Gray, has been referred to the genus Linosyris, of the old world, with which, as I conceive, they have little if any affinity, as must appear on comparing the characters of the two genera. Taking L. vulgaris for the type of the genus, we observe that the hemispherical involucrum is scarcely imbricated, leafy externally, with about one row, or scarcely two of scales, which are nearly flat; the florets very numerous, are very deeply divided; the stigmas are elongated; the summit or appendage short and ovate, much shorter than the lower or stigmatic portion. Pappus very copious, and scabrous, in several series, scarcely longer than t In allusion to its close affinity to Helianthus, 44 172 MR. NUTTALL’S DESCRIPTIONS OF NEW the achenium. Achenium oblanceolate, and compressed, sericeous villous, with only two marginal lines. Receptacle conspicuous, with alveolar margins. In the present genus the involucrum is imbricated distinctly, in three to five series of subcarinated scales, the lowest very small. The florets few in number, have a short, five-cleft border. The processes of the style are long and subulate, much exceeding the lower, naked portion. Pappus slender, much less copious, and not so scabrous as in the preceding; more than double the length of the achenium, Achenium somewhat cylindric, smooth, about five lined. Receptacle very small and smooth. *OXYTENIA.+ Capitulum heterogamous, many-flowered, the marginal ones in a single series, apetalous and feminine. Florets of the disk tubular, masculine. Involucrum composed of a single series of imbricated, ovate, rather rigid scales, (about five.) Receptaculum small and flat ; its palea narrow, spathulate and membranaceous, tufted with long hairs. Mate FLtowers.—Corolla obconic, with a narrow tube; border five-toothed. Anthers distinct. Frmate.—Corolla none. Stigmata terete, filiform, smooth. Achenia bluntly obovate, obcompressed and ridged on the inner side, covered with dense white hairs, situated beneath the scales of the involucrum and without pappus. O. *acerosa. A stout shrub? with soft wood, (a branch of which, one of the specimens, is not less than three feet long ;) every part of the plant (in a dried state; at least) covered with a fine close down, Leaves alternate, four to eight inches long, acerosely, linear and rigid, like those of a pine tree, nearly sessile, pinnatifid, with about two pair of segments, or simply trifid ; both above and below simple ; the divisions about the usual width of the leaves of the common Scotch fur, grooved beneath, but so closely revolute as to be terete. Flowers in terminal fascicles or divided branchlets. In some specimens, the capitulum appears to be smaller and the achenia more woolly, with only about ten male florets, while in others the infertile central florets are about twenty ; the latter appear, therefore, to be male plants chiefly, but they have also female flowers, which are less woolly ; involucrum roundish, of five ovate, acute, imbricated scales; male florets obconic, with a slender tube, covered with yellow glands ; anthers free ; stigmas slender, filiform ; radial florets about five, the number of the involucrum scales ; corolla none ; stigmas two, sometimes, short, linear-oblong, smooth ; achenia obovate, truncate, rigid internally, covered (particularly towards the summit,) with Jong conspicuous white hairs. A large, erect, spreading bush, with the inflorescence of an Iva; the leaves alternate, acerosely linear and rigid, pinnately divided into trific or more compound divisions ; capituli sessile, arranged in a compound panicle, as in many Artemzsias. The whole plant very bitter, but with very little aroma. In habit more allied to Artemisia than Iva.

The leaves small, except the radical ones, simply pinnatifid, with capillary and nearly simple segments, all usually terminated with a blunt gland. Pedicels elongated. Involucrum campanulate, of about eight ovate, subcarinated scales, (as usual in the genus, arranged ina single series, so that the involucrum is either hemispherical or campanulate, according to the number of its leaves or scales,) rays about eight, oval, and short, scarcely emarginate, nearly entire; the radial achenia subfusiform, curved, and embraced asin the rest of the genus, by a fold in the scales of the involucrum, crowned by a very short and blunt pappus, similar to that of the discal florets, but nearly abortive.

One of the species of this very distinct genus, (of which the seeds were sent to London from my growing plants in Philadelphia,) having been hastily referred in the Botanical Magazine to the genus Hymenoxys of Cassini, the rest of the species I described in the Philosophical Transactions have by Torrey and Gray been also placed in that very distinct genus, to which they have in fact no affinity, or external resemblance in habit. In Hymenozys, the involucrum is biserial, with rigid appressed scales, of which the interior are longer ; the achenia also are turbinate, and, as in Actinea, covered with erect, very copious, silky hairs; the rays are also, as in that genus, three-lobed at the extremity ; the pappus is always entire, acuminately awned and consimilar. They are perennials, (at least the section Ozypappus,) and one of them was referred, even by H B. and Kunth tothe genus Actinea. I have also examined specimens of two or three species of Hymenozxys, in the herbarium of Fielding, Esq. of Lancaster, (England,) and perceive no affinity. In revising my specimens, I find that the dissemilar radial florets are always embraced in a central fold of the scales of the involucrum, somewhat after the PLANTS COLLECTED BY DR.

Found as it is, in the uncultivated interior of the continent, beyond the reach of inhabitants, our plant must necessarily be indigenous. I have compared the present with the foreign plant with some attention, and I can in all cases readily distinguish them by their foliage. In the American plant, whatever be the other variations of the leaf, the attenuated points are denticulated nearly to the extremity. In the European the summit of the leaf is abruptly toothed. In the native plant, the male flowers appear to be smaller; and the scales of the cone are likewise acuminate. In some specimens, as in the European plant, the upper leaves are simply cordate, and entire, but in all cases the denticulations are smaller, and more numerous. Mr. James Read, who has long ardently studied the botany of his own country, after a distant voyage, has presented to the herbarium of the Academy of Natural Sciences, among many other curious plants of China, a small male specimen of the hop of that country, collected near Canton; and this also appears to be a form sufficiently distinct again from the European hop. From its strong armature it might be called Humunus *acuLEatus. The young stems and petioles are very sharply aculeate ; the uppermost leaves are all palmate, five-lobed, and hairy along the ribs ; the segments of the pubescent calyx are lanceolate. Has. Throughout the United States in alluvial situations. I have also most luxuriant specimens from the borders of streams in the Rocky Mountains, near the line of New Mexico, collected by Dr. Gambel. PECTOCARYA. P. PENICILLATA. Very common round Santa Barbara and other parts of Upper California. Often scarcely distinguishable from P. chilensis, except by the smaller fruit, the margin of which, as in P. chalensis, is not unfrequently pectinately bristled the whole length ; they are all, therefore, little more than varieties of each other. The plant I referred to Cynoglossum pilosum, (Gen. Am. i. p. 114,) is a true Myosotis wholly distinct from either the present plant or that of Peru. More than seven years back, I had formed a genus for this plant, (Sraurina,) of which I deposited specimens in the Herbarium of the Academy of Natural Sciences in Philadelphia. In our plant, the stigma is capitellate and emarginate, the seed cuneate-oblong, and the radicle inferior or pointing towards the style. MONARDA. M. *pectinaTa. Biennial? slightly pubescent; leaves oblong-lanceolate, denticulate, shortly petiolate ; capituli proliferous, rather small, subtended by herbaceous bracts, some of them purplish, ovate-acute, strongly ciliated, as well as the elongated setaceous teeth of the calyx; corolla widely ringent, the tube scarcely exserted beyond the calyx. PLANTS COLLECTED BY DR. GAMBEL. 183 Nearly allied to M. punctata, but with very different bractes, leaves of the same form and full of resinous punctures. The flower appears to have been pale purple and spotted. Has. Near Santa Fé, New Mexico. HEDEOMA. H, *cruata. Perennial ; minutely pubescent, branching much from the base ; leaves linear-obtuse, shortly petiolate, entire; flowers, two or three together in the axils; calyx hirsute, with long, unequal ciliate teeth ; corolla about the length of the calyx. About four inches high, very much branched, with at length a woody root. Allied to Micromeria glabella, but with smaller and entire leaves, and with the calyx of M. hirta. (Hedzoma hirta.) Has. Santa Fé. New Mexico. SISYMBRIUM. S. *rertexum. Smooth; leaves somewhat lyrate-pinnatifid, the terminal lobe toothed, upper leaves nearly entire and denticulate ; flowers small ; petals linear-spathulate, a little longer than the coloured calyx ; pods subterete, very long, nearly sessile, rigidly reflected and acuminated with the style. A rather stout species, about two feet high, with the silique an inch and a half long. It bears some affinity to Hesperis pinnatifida of Michaux, but the seeds are terete and not margined, and the pods slightly compressed and not torrulose. Has. Near San Pedro, Upper California. URTICA. U. *notosericea. Perennial and tall; leaves opposite, large, on long petioles, cordate-ovate, acute, above lanceolate, coarsely serrated, smooth, beneath silky villous, as well as the stems and petioles, the latter also pilose ; flowers tetrandrous; in axillary, filiform, compound racemes; the upper clusters styliferous only. A tall species, resembling U. procera but monoicous, and with the large leaves almost whitely villous beneath with a soft down, amidst which, however, on the stem are the usual long hispid hairs, some of the leaves are a span long without the long petiole. Male calyx four-parted, the female four-parted with two of the segments minute. Fruit ovate, pale brown and shining. Has. Near Monterey, Upper California. APIUM. A. GRAVEOLENS. (Celery.) Marshes on the coast of Santa Barbara. (Dr. Gambel.) This useful plant common to all the salt marshes of Europe, is now also found to be indigenous to the west side of this continent. 47 184 MR. NUTTALL’S DESCRIPTIONS OF NEW PEUCEDANUM. §. *PEUcELIMUM. Carpels with two of the lateral ribs undulately winged ; vitte indistinct, one or two ; commissure P. *aproTaniroLium. Somewhat pubescent, branching from the base; leaves ternately decompound, ultimate segments narrowly linear; involucels about seven to nine-leaved, the leaflets palmate, distinct, petiolulate, nearly as long as the umbellet; fruit obovate-elliptical, with a broad, winged margin, and some of the inner ribs with undulated membranaceous margins. Like many other plants of this family, there is so striking a resemblance betwixt the present species and the P. caruifolium, that at first !imagined them to be the same, yet the character of the involucrum and the fruit is so wholly different, indeed, from the rest of the genus, as to require a particular section. ‘The present is also a much larger plant than P. caruifolium, eighteen inches to two feet high; the leaves multifid, with narrow linear acute segments; petioles very short with an inflated base. The plant branching from the base into two or three divisions, umbel subtended in the two instances out of three with a proper multifid leaf; rays of the umbel ten or fourteen, with several short abortive or masculine umbelets in the centre of the umbel; several abortive flowers in each umbelet. Flowers yellow. Has. Pueblo de los Angeles, Upper California. (A single specimen, not far enough advanced to ascertain the ultimate character of the fruit.) PTEROCHITON. P. canescens. In fruit.

This plant in several collections to which it was communicated, was marked Pterocarya canescens, as far back as 1836. At the same time I marked in the collection of the Academy of Natural Sciences and elsewhere, the “ Pulpy leaved Thorn” of Lewis and Clark, by the name of ‘“ Sarcacantuus,” the Sarcobatis of Nees, and F’remontia of Torrey; by the names so marked I intended to have published these plants. Pursh’s Calligonum, which I mistook for my Atriplex canescens, must have been in the collection of Lewis and Clarke, as I did not meet with it on the borders of the Missouri. In the same journey I collected very perfect specimens of the plant since called Grayia, which I marked in the collection of the Academy Pszlocarpus. Has. In the Rocky Mountains of California abundant, and also towards the sources of the Platte, where it forms a shrub three or four feet high. PLANTS COLLECTED BY DR. GAMBEL. 185, *PHORADENDRON.+ P. *caLirornicum. Leafless; stem and elongated branches terete ; sheathing scales bifid, segments ovate acute ; berries round and few, opposite, sessile in marginal cup-shaped receptacles. Branches a foot or more in length, sometimes dichotomous by abortion, but with the branches or branchlets usually opposite. Male spikes very short, as well as those of the female ; the scales a little pubescent and acute, nearly two-parted on the stem. The first pair of scales on the male spike, subtends six flowers, or two on a side. Berries white ? and small, sessile in cup-shaped depressions of the rachis, the summit of the berry marked with the small three-cleft divisions of the acute calyx. Petals none. Has. In the mountains of Upper California. Parasitic on the trunks and branches of a Strombocarpus. This plant agrees exactly in its character with Viscum flavescens, and these, with several other American species, ought to constitute a genus distinct from the V. album of Europe; distinguished by the ordinary distinct two-celled anthers of the male flowers, which are globular, mostly trifid, rarely bifid or quadrifid, the ‘anther opens by two large terminal pores or foramina, and without filament, is attached to the sides of the three-sided torus at the base of the calyx, the anther only being free. In the female there is no vestige of corolla, a persistent calyx of three, rarely four minute triangular clefts, adhering to the summit of the globular or ovate berry ; the style is extremely short, almost sessile in the centre of a triangular fleshy disk, which also as well as the style exists in the male flower. These plants appear to be wholly American, extending from the State of Delaware to the tropics, and to a very considerable distance through the southern hemisphere ; branches usually opposite or verticellate, rarely aphyllous. To this genus I would refer the present plant P. calfornicum, the Viscum flavescens, V. villosum, V. trinervium, V. buzifolium, V. saururoides, V. tereticaule, V. martinicense, V. crassifolium, V. leptostachyum, V. peroitetii, V. brachystachyum, V. rubrum, V. berterianum, V. schotti, V. macrostachyon, V. piperoides, V. angustifolium, V. affine, V. ensifolium, V. velutinum, V. interruptum, these and most of the other American species will probably arrange with the preceding in this genus. The V. stellatum of Nepal, which I have examined, appears to be a true congener with the V. albwm, as well as V. orientale, though in the latter I have found but two adnate anthers, to four petals. A true Viscum also appears to exist in China near Canton. t From ap a thief, and devdpor a tree ; in allusion to their parasitic habit. 186 MR. NUTTALL’S DESCRIPTIONS OF NEW The present genus is well distinguished by the free anthers, which are one-celled, opening by wide pores near the summit; and by the total absence of the annular calyx and petals, the calyx being monophyllous, its base including the berry, and its three or four-toothed connivent border, which never opens, remaining persistent on the summit of the berry. In all the American species, the flowers are produced with the ripening of the berry on the lower part of the stem, so that their growth continues for the whole year. ‘The flowers, very minute, are usually sessile or partly immersed in the rachis of acylindric spike, which resembles a catkin, but differs in having the flowers disposed in interrupted clusters ; these spikes come out several from the same axil ; the inflorescence is never terminal. *CALYCODON.

D., of South Carolina; Correspondent of the Academy of Natural Sciences of Philadelphia, &c. (Continued from page 147.) Genus CARCHARIAS, Cuvier. This genus differs from Carcuaropon, in the dentine presenting a hollow cone internally, while it is solid in Carcharodon. I have seen only a single specimen from the United States of Carcharias tenuis, from the Eocene S. C., too imperfect for description. Agassiz expresses some sur- prise, that while the recent species are numerous, there are so few fossil. He met with only two. Genus GALEOCERDO, Muller and Henle. This genus, separated from GaLeus of Cuvier, comprises many species. In Gal-us the teeth are smooth on the anterior edge, and have few dentelures on the posterior—in Galeocerdo they are crenated on the whole extent, but rather unequally—the base particularly has large notches, while the point has but fine indentations. Agassiz had found specimens so uniform in the indentations of the whole contour, that he constituted a genus based on this character, which he called Corax. I have his authority for the reunion of it with GALEOcERDO, since he has seen many other specimens. In Gaeocerpo the teeth are equal in both jaws—nearly as deep as long—the anterior edge is regularly arched, the posterior strongly notched, and below the notch are the largest crenatures. The outer face is flat, the inner more or less elevated ; the root is not very thick, generally concave and parallel to the base of the crown. Of the species given by Agassiz four are from ‘he chalk, and three from the tertiary. 1. G. apuncus, Agassiz. Figs. 54, 55, 56, 57, 58.—This species is usually about a half inch in length and the same in height—occasionally longer—the anterior edge is a regular arch finely indented, the posterior angulated, more or less obtuse ; below the angle the dentelures are well marked, but are scarcely visible above. The base of the enamel is less sloped on the outer than on the inner face, where it forms almost a right angle. The root is more or less concave and moderately thick, as in all Galeocerdos. Agassiz’s specimens are from the Miocene of Kurope—mine from the Eocene of South Carolina. you 1. = : 49 192 DR. GIBBES’ MONOGRAPH OF THE 2. G. LATIDENS, Agassiz. Figs. 59, 60, 61, 62.—Is much less massive and thinner than G. aduncus, but is longer in proportion to the height. The anterior edge is less arched than in other species. The cone is short and very pointed on the posterior edge, the angle is very acute in the European species, I think less so in the American. Below the angle the dentelures are well marked, while at the cutting point and on the anterior edge they are very fine. In some specimens they are more distinct near the base on the anterior edge, while in Agassiz’s specimens he mentions the reverse, and makes it distinctive of a species. The base of the crown is parallel to the lower edge of the root on the outer face, and differs very slightly on the inner. I have several specimens from the Eocene of South Carolina, and one from the Miocene of Maryland. For the latter I am indebted to my friend F. Markoe, Jr., of of Washington. 3. G. minor, Agassiz. Figs. 63, 64, 65.—Very similar in form to G. latidens, but not arched, very small, and the cone more acute. It is almost as high as long—the base of the crown extended—the summit very sharp pointed, edged with fine dentelures on both sides. The root is thick and irregular, the enamel more sloped on the inner or elevated face. I have specimens from the Kocene of South Carolina, and from the Miocene of Maryland—the latter sent me by J. G. Bruff, Esq., of Washington. 4. G. EGERTONI, Agassiz. Figs. 66, 67, 68, 69.—This was described by Agassiz as Coraz. 'The cone is acutely pointed, and nearly perpendicular, sloped on both edges, forming almost an angle on the posterior side in some specimens. The edges are more uniformly indented than in other species. ‘The outer surface is elevated above the level of the root and undulated; the inner much more prominent and smooth. ‘The root is very thick and deep, and forms two-thirds of the height of the tooth. ‘The enamel extends lower on the outer than on the inner face. My specimens are abundant from the Eocene of South Carolina. I havea few given me by Professor Wyman, from Richmond, Virginia, and others from Calvert Cliffs, Maryland, (Mzucene) by F. Markoe, Jr., and from Hollis Cliffs, Virginia, by J. G. Bruff, Esq. The large specimen (Fig. 66) is of unusual size. It is from Pocotaligo, South Carolina, presented to me by G. C. Mackay, Esq. 5. G. PRISTODONTUS, Agass. Fig. 70.—This species is remarkable for its pyramidal form, and the great size of its crown; from the posterior edge being but slightly sloped, and the anterior forming a sort of elbow, and not a regular arc; the point is nevertheless acute and cutting. The whole height including the root about equals the length, which is sometimes three-fourths of an inch. The dentelures are FOSSIL SQUALIDZZ OF THE UNITED STATES. 193 very equal, though sometimes more strongly marked on the anterior edge. The root is thick and more than half the depth. The enamel extends much lower on the outer face. The specimen figured is the only one I have seen. It was given me by Professor Frost, of Charleston, and was sent to him from Alabama, and I am disposed to think from the company with which it came, that it is from the cretaceous formation. There is another specimen in the Medical College of South Carolina, and I think there are several in the Cabinet of the Academy from the Cretaceous of New Jersey.* 6. G. conTortus, Grbbes. Figs. 71, 72, 73, 74.—This is an undescribed species, which is very abundant in the Eocene of South Carolina and Miocene of Virginia. The cone is longer and more acute with a twist outwardly in its upper third, which is characteristic. The inner face is rounded, while the outer is undulated : the edges are regularly indented, and on the anterior next the root the dentelures are more developed. ‘The root is very thick and deep. Genus HEMIPRISTIS, Agassiz. The species included in this genus are somewhat intermediate between GALEOCERDO and Carcuaropon, but the peculiar distinctive character is in the disposition of the marginal serratures. ‘They extend only a certain distance towards the point, leaving it on both sides entirely smooth. 'The dentelures are very strongly marked, as much so as in any species of GaLrocerpo ; in other respects these teeth resemble them. ‘They are pyramidal, larger at the base, acute at the summit, and more or less curved backwards. The outer side is almost flat, the inner prominent. The enamel is perfectly smooth, and no folds exist even at the base of the crown. Agassiz described two species, but has rejected H. paucidens, and preserved H. serra. Figs. 75 to 85.—This has the form of a flat pyramid curved backwards, the edges are cutting, and the notches, which are strongly developed, are continued in some nearly to the point, while in others they are few and low down on the lateral edges. ‘They differ in this respect in the two jaws, as is the case in Notidanus and other genera. In the lower jaw they are more conical, higher, more straight at the base, and less curved at the summit. Some are very acutely pointed, so much so as to lead to the belief of there beg more than one species. I have, however, a large number, and have traced them in a series of gradual change of size from the broad to the slender forms. They are flat outwardly and prominent on the inner face, which in some specimens is compressed laterally at the lower third, so as to be very protuberant, giving them *I have lately received several specimens from New Jersey, for which I am indebted to Mr, Samuel P. Wetherill, and Mr. L. J. Germain, of Burlington, 194 DR. GIBBES’ MONOGRAPH OF THE the form of a solid triangle. The base of the crown is nearly horizontal, while that of the root is notched in the middle. The root is moderately thick. My specimens from South Carolina are all from the Eocene. I have received several from the Miocene of Maryland, from F’. Markoe, Jr., and from the Mzocene of Virginia, from J. G. Bruff, Esq. Agassiz described specimens from the Mzocene of Europe, but mentions that count Munster had specimens from the chalk which he thought similar. Genus GLYPHIS, Agassiz. The teeth of this genus are peculiarly formed. They are lanciform, with a thick solid and expanded base. The body of the cone is awl-shaped and a little below the point is wider, resembling a graver. The upper portion next the point is flat and finely dentelated, while the lower part is free from serratures, and in some specimens rounded. Agassiz describes a single species G. hastalis, from the London clay. G. suBULATA, Gibbes. Figs. 86, 87.—In this species the cone is shorter and thicker proportionally than in G. hastalis, Agassiz, and is more straight, convex on both surfaces, more so on the inner ; the upper third of the outer face is flat, and the point, which is compressed, has a tendency outward. A sharp lateral edge extends from the apex equally on both sides two-thirds the length of the cone, and is finely and uniformly indented. The root is thick ; the enamel extends lower on the outer face and tothe root on both. In the smallest specimen figured, the root is very broad and not so thick, and the enamelled base has fine dentelures. The specimens figured are all I have met with, and are from the Eocene of South Carolina.* Genus SPHYRNA, Rajinesque. ZYG/ENA, Cuvier. The form of the hammer-headed sharks is very remarkable, but there is nothing as peculiar in the character of their teeth by which they can be readily distinguished when isolated, and they differ in the two jaws. The outer face is flat, and the inner prominent, the marginal indentations are very minute, though often absent, especially in young and lower teeth. S. prisca, Agassiz. Figs. 88, 89, 90.—These are flat, thin, and triangular, sharp pointed, the apex turned back; the enamelled base extended equally on both sides from the cone; the serratures are very minute, in some specimens not visible to the naked eye, and in others absent, except on the lateral basal extension. The root is thick, flat on the outer, and convex on the inner side. *I have recently received several specimens from the Green Sand of New Jersey, presented by Mr, §. P. Wetherill. , FOSSIL SQUALID OF THE UNITED STATES. 195 These teeth are often found precisely similar except in being crenated and smooth, the former most likely belonging to the upper and the latter to the lower jaw. Agassiz describes specimens from the chalk of Malta, and from the Swiss molasse ; all mine are from the Eocene of South Carolina. S. Lata, Agassiz. Figs. 91, 92, 93.—Distinguished by an enlarged and pyramidal form, as well as by the well marked though fine dentelures over the whole contour of the edges; anterior edge somewhat rounded, posterior notched, outer face flat, inner swollen. The enamel extends low down on the root, which is very thick. The locality of Agassiz’s specimens was unknown. Mine are from the Eocene of South Carolina. S. DENTIcULATA, Agassiz. Fig. 94.—Professor Agassiz is in doubt whether this species differs from S. prisca. The perpendicular form and acute isosceles-triangular form, and regular distinct and symmetrical denticulations induce me to think it a Separate species. I have, however, seen but a single specimen, the one figured. Genus NOTIDANUS, Cuvier. “In the genus Normanus, the teeth are not only of different forms in the upper and lower jaws, but also vary considerably in this respect, at the anterior and posterior regions of the same jaw. In the upper jaw, the anterior teeth are large, compressed triangular plates, with the pointed apex arched backwards, and the margins slightly dentated, except in the two anterior ones. The posterior teeth are in the form of simple obtuse furrowed tubercles. In the lower jaw, the large anterior teeth have the apex less produced; the anterior margin is finely serrate, and the posterior divided into three or more denticles. ‘The posterior minute teeth resemble those in the upper jaw. Of the larger teeth there are rarely more than four in each vertical row.”’—Owen.* N. PRIMIGENIUS, Agassiz. Fig. 95.—I have given a figure of the only perfect specimen I have met with, and think it belonged to the lower jaw. It was kindly presented to me by Professor J. Wyman, of Boston, who procured it from the Eocene of Richmond, Virginia. I have fragments from other localities. The crown consists of a series of sharp oblique cones, of which the first is the largest and least oblique, the others gradually diminishing in size towards the posterior edge. The large cone is strongly indented on its lower outer half. The length of the tooth greatly exceeds its height; the inner and outer faces are both prominent and differ *Besides those of Agassiz, good figures are given of various forms of Notidanus in the old work of Scrixa, De corporibus marinis, Rome, 1747, and in the recent elaborate work of C. L. Bonaparte, Iconographia della Fauna Italica, Rome, 1832—1841. I find also others in Oryctographie de Bruzelles, by F. X. Burtin, Bruxelles, 1784. 50 196 DR. GIBBES’ MONOGRAPH OF THE very little, though the enamel is lower on the inner surface. The root is thick, and equal in depth to the height of the principal cone. Agassiz has met with no fossil teeth of the upper jaw. He describes several species. Genus LAMNA, Cuvier. C. L. Bonaparte, and Muller and Henlé, include under Lamna four genera— Lamna, Cuvier; Oxyrhina, Agassiz; Carcharodon, Smith; and Selache, Cuvier—all the characters being drawn from the external form, and no regard being had to the skeleton or teeth. These genera have teeth so dissimilar that they are easily distinguished; but Odontaspis, which is included in another family, has teeth so like Lamna, that when detached they cannot with certainty be distinguished. Agassiz is doubtful about separating them, though there are some fixed differences which will aid in classing species. ‘Teeth of Lamna are flat, and approach in form Ofodus, from which they differ in being of less breadth, and having smaller lateral cones. Those of Odontaspis, on the contrary, are more cylindrical, more twisted, and have lateral cones longer and more pointed. The number varies—Odontaspis taurus has usually only one on each side, while O. feroz has two, sometimes three. Agassiz includes under Lamna all straight teeth provided with small lateral denticles, and doubts when the species described seems. to approach nearer te Odontaspis than to Lamna cornubica. When well preserved, there is no difficulty in distinguishing Lamna from Ozxyrhina, since the latter have no lateral denticles. The distinction is more difficult with Otodus, as Lamna compressa and Otodus appendiculatus. He also includes under Lamna another type, which he thinks should form a separate genus, Sphenodus. 1. L. ELecans, Agassiz. Figs. 96 to 102.—Lanciform, regular and straight ; thickness considerable towards the base of the root, but tapering off towards the point. Inner face ornamented with vertical strie, very fine and numerous, very distinct near the enamel, extending above the middle of the cone. This is a distinctive character, which we usually find better preserved in small teeth. The lateral denticles are very small points, sometimes absent, the root is thick, with the branches well developed. Outer face plane or a little elevated, inner very convex so that the tooth has almost the appearance of a slender cone cut through the middle, the edges are smooth and cutting. ‘The enamel extends lower on the outer face, the base straight and horizontal, while it is curved on the inner. This species is very common in the Eocene. I have fine specimens from Claiborne, Alabama, kindly sent me by C. S. Hale, Esq., of Mobile, from Richmond, Virginia, by Professor Wyman, and from Maryland by J. G. Bruff, Esq. In South Carolina they are abundant. FOSSIL SQUALID/E OF THE UNITED STATES. 197 Agassiz mentions them from the Crag (Mzocene) of England. I have not met with them in the Miocene of the United States. 2. L. cuspipata, Agassiz. Figs. 103 to 106.—This species is described by Agassiz as common in the Swiss molasse, (Mzocene.) Ihave it from the Eocene of Washington, Georgia, from Rev. George White, of Savannah, and from the mouth of Potomac Creek, Virginia, presented me by J. G. Bruff, Esq. It is very like L. elegans, is in general very thick, of moderate breadth, equilateral, straight, or a little curved back. The edges are smooth and cutting the whole length; external face perceptibly elevated ; inner.more so. The base of the enamel, which is smooth, is usually sloped at a right angle on the outer face, which is not as well marked on the inner. The peculiar distinction from JZ. elegans is that it is smooth on both faces, having no strie. The root is more largely developed than in other species, and cases occur where the branches exceed in length the height of the cone. Agassiz now refers L. denticulata to this species. 3. L. compressa, Agassiz. Figs. 107 to 112.—These resemble much in general appearance the small teeth of Otodus obliquus. They are more flat and less broad, the root is less prominent, and the passage to the crown less marked. They are more lanciform, and the cone more slender than in Ofodus. The denticles are irrecular, generally larger in the posterior teeth. All my specimens are from the Santee Canal, (Hocene,) South Carolina, Agassiz described this from imperfect specimens, as Ozyrhina leptodon, which he now withdraws. 4. L. acuminata, Agassiz. Figs. 113, 114, 115.—This species is of medium size, very thick at the base, edges cutting, nearly equal, outer surface flat, curved outwardly near the apex; inner face prominent ; lateral denticles well developed ; root thick. I have met with only three specimens, all from the Eocene of Orangeburg, South Carolina. 5. L. crassipEens, Agassiz. Figs. 116, 117, 118.—The name of this species indicates its form, which is short and thick. The outer face is flat, the inner prominent and curved backward, the root very thick, and prominent inwardly; edges cutting. Found in the Hocene of South Carolina. 6. L. (Odontaspis) CONTORTIDENS, Agassiz. Fig. 119.—Agassiz describes this as of a subulate irregular form, much curved inwardly, its internal face having distinct folds from the base to the summit; the root well developed and thick, the branches 198 DR. GIBBES’ MONOGRAPH OF THE of the root of moderate size and approaching, the outer face near the point is plane, lower down, and on the inner rounded, the edges near the point are alone cutting ; the base of the cone cylindrical. I have seen but few specimens answering this description, and the latter characters, the cutting edge and the cylindrical form of the base are the only points in which it differs from Lamna elegans. Agassiz describes it as abundant in the Miocene of Europe. Ido not know the locality of the specimens I have, which are figured. I am lately indebted to Lieut. J. W. Abert of the Topographical Corps, United States Army, for two specimens of teeth (Fig. 119, Pl. xxvi.) from the Cretaceous formation at Poblazon, in New Mexico. They are well marked specimens of Lamna contortidens, and are figured by him in his published report to the Secretary of War. 7. L. (Odontaspis) HoPE!, Agassiz. Figs. 120, 121, 122, 123.—This is the broadest of the subulate teeth, some are thick others more slender, all are nearly cylindrical at the base, edges prominent and cutting towards the point, in proportion as the tooth is flat, root thick and narrow. The nutritive canal is very perceptible at the most prominent part of the inner face of the root. The lateral cones are small and awl-shaped, often rudimentary, seldom preserved in large teeth. Outer face flat near the point, insensibly rounded towards the base, where it is almost as round as on the inner, compressed laterally, smooth, no trace of striz. Found in the Eocene of South Carolina. &. L. (Odontaspis) veRTICALIS, Agassiz. Figs. 124, 125, 126, 127.—Not as twisted as L. Hopei, nor like L. compressa, because thicker: nor like L. elegans, because there are no strie on the inner face. ‘The prominent characters are straightness and thickness at the base of the enamel, and of the root. The edges are cutting even to the root. Lateral denticles are well marked, base of the enamel more sloped on the outer than on the inner face ; the nutritive foramen distinct. My specimens are from the Eocene of South Carolina. 9. L. (Odontaspis) cractuis, Agassiz. Figs. 128, 129, 130.—This is the most slender of known fossil Lamne, is very slender, has cutting edges the whole length, outer face flat, inner sensibly swollen, no strie on inner face ; branches of root well developed. I think L. subulata, Agassiz, identical with this species. From the Eocene of South Carolina. . Genus OTODUS, Agassiz. This is known only fossil. Agassiz has established it as intermediate between Ozyrhina and Lamna and Carcharodon, but easily distinguishable from both. It differs from Carcharodon by the entire absence of marginal dentelures, which are of FOSSIL SQUALID OF THE UNITED STATES. 199 importance, especially in fossil species. The species are in general less in size than Carcharodon, and the largest are seldom as large as the smallest cf them. It is more difficult to distinguish Otodus from Ozxyrhina; it has the same broad flat form, smooth at the edges, but Otodus is specially characterized by the presence of a lateral denticle on each side, usually equal; often it is rounded, sometimes compressed and sharp, rarely angular or indented. Lamna and Odontaspis have it, but always smaller, cylindrical, and more pointed and lanciform. The root is largely developed, very deep and thick, but has no elongated branches as Lamna. When the root and lateral denticles are detached, it is hard to distinguish Lamna from Otodus and Ozyrhina. Agassiz describes several species as of doubtful genus on this account. 1. O. optiguus. Figs. 131 to 137.—This species is common in New Jersey, whence there are fine specimens in the Cabinet of the Academy. I have casts also of several from Mr. C. Barclay, of Troy, from the Eocene of New Jersey. 1 have no specimen of O. obliquus from South Carolina. It is massive, with a well developed root, so large that in some the depth equals more than half the height of the crown. The outer face is nearly flat, grooved longitudinally in the middle at the base of the enamel, the inner surface is very prominent, viewed en profil the root seems deeper on the inner face, where is a space deprived of enamel; below this the root is thickest. The lateral appendages are thick and irregular, more developed in arched than in upright teeth. Agassiz thinks the presence of the lateral denticles not important for species, but much so for the genus. The prominent character of Ovodus obliquus is its massive size and preponderance of root. ‘The enamel is dense and very full at the base of the crown. The species described as Otodus lanceolatus, by Agassiz, he thinks most probably belongs to O. obliquus. 2. O. APPENDICULATUS, Agassiz. Figs. 138, 139, 140.—Distinguished by large lateral denticles, compressed and usually obtuse, but some are very sharp. The root is not large, and thinner, and not so deep as that in O. obliquus ; base of the crown nearly horizontal. The root is absent in two of my specimens, which are from the Green Sand of New Jersey. 3. O. Levis, Gibbes. Fig. 141.—The tooth here figured I published* as new, and upon reference to the figures given by Agassiz, I find he has one resembling it, (Fig. 7, Tab. 32,) which he doubted about separating from O. appendiculatus. The following is my description : * Proceedings of Academy, September, 1847. 51 200 DR. GIBBES’ MONOGRAPH OF THE “Oropus levis. —This has very much the form of Lamna cuspidata, but the position, form and size of the lateral winglets, mark it as a true Otodus. It is more slender than any other of this genus, lanciform, equilateral, straight, convex on the inner face, and undulated on the outer from a triangular depression near the base, extending longitudinally nearly to the apex. The lateral cones are broad and thick, and detached from the base of the enamel, which extends lower on the outer face than on the inner. I have a single specimen (Fig. 141) from the Locene of South Carolina.” I have since seen one in the cabinet of the Academy from New Jersey. 4, O. crassus, Agassiz. Fig. 142.—This species is distinguished by a considerable thickness, but not as thick as O. obliquus. Contrary to other species, the root has not a marked preponderance. Instead of the outer face being swollen, or strongly prominent, in this it is flat, even at the base of the enamel. The height of the cone does not equal the length of the root. ‘The surface of the enamel is finely striated on both faces. 'The lateral cones are absent in the only specimen I have seen, but of the identity of the species I have no doubt. It is from the Cretaceous of Alabama. 5. O. Macrotus, Agassiz. Figs. 143, 144.—This is flat in proportion to its size, and is characterized by large compressed, rounded, lateral denticles, detached from the principal cone. The outer face is a plane, the inner full, moderately rounded: with faint strie visible. The base of the enamel is nearly horizontal, and equal on both faces. The larger specimen figured (Fig. 144) is from the Eocene of South Carolina, the smaller (Fig. 143) from the mouth of Potomac Creek, Virginia, given me by J. G. Bruff, Esq. 6. O. TRIGONATUS, Agassiz. Figs. 145, 146.—These are small teeth on an elongated base. The cone is straight, pointed, and narrow, with sharp edges. The thickness is not great, the outer face is flat, the inner convex. The lateral denticles are rounded. From Santee, (Hocene) South Carolina. 7. O. avicuLatus, Agassiz. Fig. 147.—This species is on the confines of Otodus, resembles Ozyrhina hastalis, but may be distinguished by a very minute lateral denticle on each side of the cone. It is sharp pointed, the apex a little turned back. The anterior edge is straight or slightly arched, the posterior curved. The outer face is plane, the inner swollen, though less so than in other species of Otodus, which makes it so flat. I have figured the only specimen I have seen of this species, from the Kocene of South Carolina. FOSSIL SQUALIDZZ OF THE UNITED STATES. 201 Genus OXYRHINA, Agassiz. This genus is established on the character of the absence of lateral appendages in teeth allied to Otodus. It is an important character in fossil genera and species, and the distinction can only be doubtful when the base and root of the specimen are imperfect, as there is then a difficulty in assigning it to Otodus, Lamna, or Oxyrhina. Ozyrhina is generally known by its broad lanciform shape, differing from Lamna which is always narrow and straight. The resemblance is greater between Otodus and Ozyrhina—Otodus is generally larger, more triangular, thicker, and not so flat. The root of Oxyrhina, particularly is less thick, and the branches less developed. In other respects Ozxyrhina approaches Lamna. 1. O. HASTALIS, Agassiz. Figs. 148 to 152.—The variety of form and dimensions of these teeth, according to their position in the jaw, render their distinction difficult. They are large, elongated and lanciform, the larger teeth mostly equilateral, probably occupying the front; others are more or less arched, very thin, not half as thick as the breadth of the base of the enamel. The root is never as prominent as in Otodus, _ and the terminal portions less developed. The inner face is regularly convex from the base to the summit, and serves to distinguish this species from Oz. xiphodon, which is more flat on this side. The base of the enamel is slightly sloped on the outer face, and descends lower on the inner, and is more hollowed on that face. The outer face is flat; on each side parallel to the edge is a vertical furrow, which extends two-thirds or three-fourths of the height; the middle is slightly prominent, with a small depression near the base of the enamel. I have specimens from the Miocene of South Carolina, from T. W. Porcher, Esq., from the Miocene of Virginia and Maryland, from J. G. Bruff, Esq., and F. Markoe, Jr., and from the Hocene of South Carolina. 2. O. xtpHoDON, Agassiz. Figs. 153, 154.—There is asingle prominent character which distinguishes this species from Oz. hastals, viz., on the inner face, which is ordinarily regularly rounded, at the base of the enamel, is a remarkable flattening, as if ground; unless this face be well preserved you cannot distinguish it; usually Ox. xiphodon is larger. All are curved outwardly at the summit. The base of the enamel is almost the same on both sides, a little lower on the outer face. The root, though a little thicker than the base of the crown, is still less developed than in other species. On the outer face are parallel furrows next the edges, which give it an undulated appearance. The specimens I have seen are all from the Eocene of South Carolina. Agassiz now considers Ox. quadrans and Oz. retroflexa as forms of this species. 202 DR. GIBBES’ MONOGRAPH OF THE 3. O. pLicaTILis, Agassiz. Figs. 155, 156, 157.—This is broad, flat and of moderate thickness, resembling somewhat Oz. ziphodon. It is distinguished from all others of this genus, by having folds on the outer face at the base of the enamel, numerous and well marked in the middle of the tooth. There is a broad furrow near the edges, and two others exist next the middle. The root is thick, without lateral branches, the base of the enamel is parallel on both faces to the base of the root. Agassiz described this species as always straight, and Oz. retrofleca as distinct from its oblique form. He now considers the latter as belonging to Oz. ziphodon. Ox. trigonodon he thinks should be referred to this species. My specimens are mostly from the Muzocene of South Carolina, though I have several from the Eocene. 4, O. MANTELLII, Agassiz. Fig. 158.—This resembles Oz. hastalis and Oz. xiphodon, but is much thicker and has the root better developed. ‘The outer face is flat, with furrows next the edges on the lower half, and a depression in the middle at the base of the enamel, the surface is thus undulated. The inner face is regularly arched, the anterior edge is arched and the posterior curved in the specimen figured. The enamel is horizontal at the base, the root thick and distinctly separated into branches. The only specimen I have seen is from the Cretaceous of Alabama. 5. O. crassa, Agassiz. Figs. 159, 160.—Is very massive, thicker than any species except that which I will describe as Ox. Desoriit. It is curved inwardly, the outer face is elevated and presents faint traces of furrows, which are so developed in Oz. hastals. It is nearly equilateral, the edges cutting, though thick, the point tends outwardly ; the root is very thick, the base of the enamel angular on the outer, arched on the inner face. My specimens are from the Eocene of South Carolina. 6. O. minuta, Agassiz. Figs. 161 to 164.—This species is quite small. They are sub-cylindrical, with point and edges rather obtuse. They are mostly straight ; the root very thick in proportion to the size of the teeth. Numerous in the Hocene of South Carolina. 7. O. sittimani, Gzbbes. Figs. 165 to 168.—Among twelve specimens from the Eocene of South Carolina, there is much uniformity. The cone is straight or very slightly bowed on the inner edge, equilateral, acutely pointed, both surfaces convex. the inner more so. A peculiarity exists in the great breadth of the enamel at the base, which is similar on both aspects. The root is thick, and forms one third of the height of the tooth. I attach to it the name of Professor B. Silliman, the veteran co-labourer in American science.* *Ox Desorru and Oz. Sillimani were described in the Proceedings of September, 1847. FOSSIL SQUALID OF THE UNITED STATES. 203 8. O. pEsori, Gibbes. Figs. 169 to 171.—Professor Agassiz described under this name specimens, which subsequent experience induces him to consider identical with Lamna cuspidata, with which he had noticed a resemblance. I take pleasure in restoring the name of the distinguished M. Desor, the friend and co-labourer of Agassiz, in this department of science, to a fine species in my Cabinet - It is very massive, thicker than any other of this genus, in this respect resembling Ov. crassa, but not so broad. Viewed en profil, the form is similar to Lamna Hoper, much curved inwardly, except near the apex, which is flat. The edges are cutting in their whole extent, the base of the enamel arched, and nearly equal on both faces, the root very thick compact and heavy. I have several specimens from the Miocene, and others from the Hocene of South Carolina. 9. O. witsonut, Gzbbes.—F igs. 171, 172,173.—This resembles somewhat Oz. hastalis , but is convex on the outer face, the root also is thicker and more largely developed. The cone is straight, equilateral, and very acute, slightly curved near the base. The root is very convex on the inner and concave on the outer face, the branches irregular. The enamel is arched on the inner face, and waved on the outer. I believe this species distinct from other American varieties, and propose for it the name of Dr. Thomas B. Wilson, the patron of the Academy. When I commenced my investigation of the Fosszl Squalide, it was my purpose to attempt a microscopic arrangement. Professor Agassiz having informed me of his intention to undertake such researches, both of the recent and fossil genera, I prefer to yield to his experience and opportunities what I could but partially and imperfectly effect. In the present state of our knowledge, it is convenient to make a pro tempore division of the Squalde, into those having crenated teeth, and those which are smooth, as follows : 52 204 DR.

Conran. a UPPER EOCENE FOSSILS. CLAVELLA, Swainson. F'usus, Lam. C. vickspuRGENSIS.—Fusiform, smooth, moderately thick; volutions eight, with straight sides; spire conical, with obtuse longitudinal remote varices, first and second volutions entire ; suture impressed ; body whorl regularly rounded towards the beak; aperture and canal about one-tenth longer than the shell ; beak straight and pointed. 24. 3. Locahty. Vicksburg, Mississippi. Abundant. FULGUR, Mont. F. noputatum.—Pyriform, thick, with strong rugose revolving lines, with a very fine intermediate line between most of the large strie; on the inferior part of the body whorl is a space without lines, below which the whorl has a slightly concave slope towards the beak; angle tuberculated, the series continued on the spire near the suture: in some specimens the tubercles margin both sides of the suture ; spire short, the sides of the volutions concave; labrum with rather distant prominent acute lines within ; beak straight. 13. 3. Locality. Occurs with the preceding. This species is easily distinguished from F. spiniger, (Fusus spiniger,) of the same locality, by its much less prominent spire, and by having tuberéles in place of spines. TRITON, Mont. T. suBaLveatum.—Subfusiform ; varices obsolete, except one near the margin of the labrum, which is broad ; revolving sulci in pairs with a broad flattened interval ; longitudinal wrinkles distinct and the longitudinal ribs or varices numerous, narrow and obscure, except on the spire where they are more prominent ; sutural area subcanaliculate ; aperture wide ; labrum with remote prominent lines within ; columella with a prominent plait near the middle and another near the angle of the aperture. Locahty. Occurs with the preceding. The three fossils above described occur near the base of the cliff at Vicksburg, in company with Natica Mississippiensis and Corbula alta, all abundant, and none have been found in the group above, except one valve which I supposed to be of the last named species, when I saw it at Vicksburg. As I have not access to the specimen, 53 208 MR. CONRAD’S DESCRIPTIONS OF I cannot say certainly that it is the same with the C. alta. These shells are situated below the indurated marly beds which contain the remains of crabs, as I am informed by J. D. Anderson, Esq., of Vicksburg, who collected the specimens. The stratum near Dr. George Smith’s plantation, about six miles N.

XVI.—Notes on Shells, mith Descriptions of new Genera and Species. By T. A. ConraD. CASSIS. C. cornuta, Lin. Two species of Cassis have been confounded by authors since the time of Linné, under the name of C. cornuta, one of which inhabits the East, the other the West Indies. Linné gives the latter habitat, but his reference is solely to figures of the eastern shell, and it is therefore probable that his description was taken from that species, though the name better applies to the other, which is really horned when old, whilst the eastern shell has much shorter and more numerous tubercles: these never become so greatly unequal in size as in the former species, which shell is well represented in Chemnitz’s figures, 1790 and 1791.

WITH DESCRIPTIONS OF NEW GENERA AND SPECIES. 213 I am indebted to Dr. Thomas B. Wilson for the opportunity of examining the three foregoing species in different periods of growth, which removed all doubts about the specific differences of each. The young nobilis has the same dilated form as the old shell. The young of the other two species are on the contrary very slender. In the variegatus and nobilis there isa much larger proportion of the dark waved bands to the white or light coloured shell, and in every stage of growth the former is thicker and heavier than in corresponding ages of the others. NAUTILUS. N. perroratus.—Suborbicular, umbilicated ; margin deeply sinuous; colour white with brown irregular transverse rays, becoming distant, and inclining to flesh colour on the margin of the wider portion of the shell ; margin of aperture blackish-brown within.

This shell has been referred to NV. umbilicatus, Chemnitz, (N. scrobicuiatus of Solander and Dillwyn,) but it has not the flattened sides nor wide umbilicus of that species, and the rays are much darker. It more resembles the pompilius, but the umbilicus and narrower aperture readily distinguish it. It is about the size of that species. PETRICOLA. P. catirornica.—Sazicava californica. Journ. Acad.

This shell which Deshayes referred to Panopea, has a highly perlaceous substance, and is destitute of cardinal teeth. The nacre, and different form of the muscular impressions, appear to me sufficient to exclude it from Glycimeris, Lam., to which it approaches nearer than to Panopea, Aldrov. If this Miocene fossil is inadmissible in the genus Pholadomya, I propose a new generic name, Margarilaria. PARAPHOLAS, Con. Shell pholas-like ; dorsal margins widely folded over the valves; accessory valves two, nearly similar in form, elongated, one extending from the umbo to the posterior extremity ; the other united to the base ; hinge plate thick ; adductor muscular impressions greatly elongated. The peculiar character of the accessory valves which appear as though soldered to the shell; the elongated muscular impressions so different from those in other genera of Pholadide ; the form of the pallial impression, and the valve on the base, prove a very distinct organization in the animal, and marked distinctive generic characters. The accessory valves are only two, with a medial suture, and are much alike in form, the dorsal valve being shortest and truncated at the beak. On the back there is a strong resemblance of four other valves caused by a wide folding over the valves. The pallial impression descends in a nearly direct line from the adductor muscle to an elongated cicatrix, of an oblong square shape, which joins the basal margin. P. catirornica, Con... Journ. Acad.

XVII.—Remarks on the Birds observed in Upper California, with descriptions of new species. By Wituiam Gampet, M. D. (Continued from page 56.) PIAYA, Less. 111. P. cayanensis, Gamb. Cayenne Cuccoo. Cuculus cayanensis, Briss. Vol. iv. p. 122, (1760.) C. cayanus, Linn. Syst. Nat. ed. 12th, (1766.) We found this beautiful bird common about the Gulf of California, particularly at Mazatlan. There is a good deal of variation both in size and colour in this species, probably dependant on age. ‘The colour above on young birds is pale cinnamon, but in old specimens it becomes of a much deeper reddish, with beautiful purple reflections. “The tail beneath also changes from the colour of the upper parts to nearly a pure black. There is much variation also in the size of the bill, and length of wings and tail; but one specimen which we have in the collection of the Academy, from Surinam, exceeds all the others so much, that we purpose to make it different under the name. P. macroura. Its total length is 22 inches, of which the tail is 15 inches: wings 63 inches: tarsus 1? inches. The plumage is almost exactly the same, though less tinged with red above, and the front and top of head more inclined to dusky grey. Its broad expansive tail presents beautiful purple reflections; beneath it is almost black, each feather with a white tip. GEOCOCCYX, Wagler. 112. G. mexicaNnus, Strick. Paisano.

The Hoitlalotl, or Long Bird of Hernandez, was said to inhabit the hottest parts of Mexico; to fly near the ground, making but short flights, but ran so swiftly that it far exceeded the speed of the swiftest horses; and that its flesh was not much esteemed for food. ‘The length of the body was nine inches, and the tail in addition about a span, or a total of about eighteen inches, and the tail green with purplish reflections like the peacock. All of which is true of the Paisano only, and together with the rest of the description given by Willoughby and Ray, leaves but little doubt that this is the bird which was intended to be described. As we know, therefore, that the name mexicanus was first given to it as the bird of Hernandez, it should be retained, although the description be so imperfect. It is distributed throughout the greater part of Mexico, where it is well known by the name of paisano, or countryman, and in California as the correcamino, or road- runner. We also found it occasionally on the route from New Mexico to California, and I have seen several specimens from Texas. Its swiftness of foot is proverbial, and the astonishment of all who see it ; indeed it is said in many places to be chased on horseback by the Mexicans for amusement. I have heard of its being tamed at Chihuahua and other places, and kept about the houses to rid them of vermin, such as scorpions, lizards, centipedes, &c., which are there socommon; and judging from the contents of the stomach of one which I opened in California, they would be useful enough for this purpose, for it contained to my astonishment, beside other small matters, nine very large grasshoppers and a good sized lizard whole ! [ have been told by the Californians, that they have a method of killing snakes which, if true, is sufficiently remarkable : that is, when they find a snake coiled up and asleep, to encompass him with the joints of a round-stemmed cactus, with long very piercing barbed spines, whicl. is common in many places, and then to drop a joint upon his coil; the snake by his twisting is pierced in all directions and soon killed. I have observed them to freque:t principally the barren bushy plains, and especially those which are covered with several kinds of cacti; probably because in such places lizards are also abundant. I have found their bills and feet covered with dirt asif they had been both scratching and digging. They will fly for a short ‘distance when first surprized, but if chased do not rise, running with the wings a little open and the head erect. DR. GAMBEL ON THE BIRDS OF CALIFORNIA. 217 This genus contains at least two well marked species differing in size and colour. The G. affinis is much smaller, with the bill quite moderate, and the plumage above with reddish bronzed reflections ; beneath it is pale ochraceous, with the anal region dusky rufous: the breast and sides of neck are sparsely marked with longitudinal black streaks occupying the centres of the feathers. The G. mezicanus has the upper plumage bronzed with steel blue and brownish green reflections. On the breast and sides of neck the webs of the feathers are more loose and setaceous, black in the centre, on either side, with broad reddish ochraceous margins ; all the rest of the woolly feathers beneath of a dirty grey colour. Nothing is more remarkable in these birds than the variation in size to which the bill is subject. This led me to suspect that among the specimens in the collection of the Academy, there were four species, but finding scarcely any difference in the other proportions or colour, I conclude that the bill is subject to very great modification in size and form according to age; which, in fact, is the case in most of the American cuculide. In two specimens of the G. affinis the measurements of the bill are as follows : 1st specimen. 2d specimen. - Length of from nostril to tip, - - - 8-10ths of an inch, 1 inch and 1-10th. « © lower mandible from the junction of rami to tip, 5-10ths cS 73-10ths of an inch. « ~~ from angle of mouth, - - - 1 inch and 63-10ths. 2 inches. The smaller one appears to be in perfect plumage, and its colours more brilliant than in the one with the largest bill. The tail, wings and tarsi are nearly equal in both. A specimen of G. mexicanus brought from Buena Vista by one of the army officers, is smaller in every way than the other specimens, but is a young bird. The wing is half an inch shorter, the tarsus shorter, and the bill from angle of mouth five-tenths of an inch shorter, and from nostril to tip one inch and two-tenths, instead of one and a half inches. From Saurothera it only differs in the character of the plumage: the margins of the mandibles are ragged, not serrated, in both ; indeed the lacerated appearance is most probably only the result of wear and tear, either in the living bird or in dried specimens. It at first seemed strange to me that Boie should have placed this bird in his genus Diplopteris, but if the very short-billed specimen of the G. affinis is compared with Diplopteris nevius it will be difficult to find a generic distinction COLUMBA, Lunn. 113 C, rasctaTa, Say.

Small flocks of this noble pidgeon frequent the woods of California during winter, but are extremely shy. 114, C. cAROLINENSIS, Linn. Common Turtle Dove. We found this species breeding on the prairies near the rivers Arkansaw and Cimaron, in June, forming their nests on the ground at the foot of large tufts of grass. It is common about Santa Fé, and was occasionally seen by us on the road to California, where it is a constant denizen of the vineyards and orchards. CALLIPEPLA, Wagler. 115. C. caLirornica, Gould. Californian Crested Quail. Perdiz californica, Lath. This beautiful bird is extremely abundant throughout California; in the winter season congregating in large flocks, sometimes of as many as a thousand or more, in those places where there are woods enough to afford covert for so many. They also resort to the bushy plains and ravines of the hills. Displaying all the watchfulness of our Virginian Quail, they are even more swift of foot, eluding pursuit by running and hiding with surprising speed; but upon sudden alarm, are more apt to fly into the trees, where they lie close upon the horizontal branches like so many squirrels, which added to their colour, resembling somewhat the bark, renders them difficult to be seen. They are exceedingly graceful in their deportment, and when running have the crest elevated and thrown backwards, but when at rest, walking on the ground or over piles of brush, carry it curved forward overhanging the front. The nest is formed upon the ground at the foot of a tree, or under cover of a bush. The number of eggs is sometimes very great, as in the instance of one which I found at Monterey, July 20th. It was a shallow hole scratched in the ground at the foot of an oak tree, with a few blades of dried grass around the sides but bare at the bottom, and contained twenty-four eggs! I judged from the appearance of them, that two birds had laid in the same nest, as fifteen of them were of a different shade from the others. 116, C. Douciassu, Gamb. Douglas’ Crested Quail.

They were numerous in flocks of fifteen or twenty, running about in company with another species which I thought new also, but the specimens I had procured, whilst engaged in skinning this, were devoured almost at my elbow by a couple of hungry Ravens. Several spiral podded species of Prosopis, with low spreading branches, afforded them excellent covert, and the seeds of bushy malvas, chenopodiums and artemisias, probably served them as food in that dreary region. 118.

Length 9 inches : bill about 1 inch, dark brown: irids hazel: legs umber-brown : tarsus 1 inch. This remarkable species, so distinct from the common Turnstone, is abundant throughout the coast of Upper California. I first met with it in the Bay of St. Pedro, in February, flitting over the rocks with great activity, and uttering as it flew a creaking twittering note. The plumage of the living bird is of a beautiful dark golden green, which contrasted with the pure white of the upper tail coverts, and the double white bands of the wings when expanded, renders its appearance when flying extremely beautiful. ; I afterwards found it common along the rocky coast, particularly at Monterey, in November ; and observed that it preferred the roughest rocky points and broken stony banks, lashed continually by the foaming surf. Here it delights to run over the rocks covered with sea weed and small shells, rising for a minute on the wing to avoid the dashing breaker, and alighting the moment its fury is spent, to glean its well earned fare amid the rustling foam, in which they are often enveloped. ss ave “, DR. GAMBEL ON THE BIRDS OF CALIFORNIA. aol When flying, they utter a rapidly repeated trilling twit twit tit. Gray in his Genera of Birds has abandoned the name Strepsilas, and given Cinclus of Moehring for this genus. In my opinion, we might as well go back to Gesner and Aldrovandus for names, as to Moehring, and it is but right that we should, for the names they gave to well known birds, are as much matters of history as names given by authors at the present day. The “inflexible law of priority ” must, as a matter of necessity always hold good, to prevent an otherwise ever- varying and endless confusion ; and if we adopt it, how can we with justice reject the names given by the very earliest writers on the subject, if they characterize the species in such a way that we can recognize them? It has been assumed that the binomial system of nomenclature was first established by Linneus, and that we owe the compliment to that great man, not to take any of the names of the older authors: but will the world think so a century hence, when the system of Linneus will appear as imperfect, as the systems of the older authors do to us now ? Neither can I agree with those who think that we owe the first distinct idea of genus and species to Linneus. But in regard to this genus the name Strepsilas can with propriety be retained, because that Cznclus was used before Moehring’s time for the Tringas ; Arenaria of Brisson was previously used for a well known genus of plants; Morinella of Meyer, 1810, which is the same as Morinellus, was first used for the Eudromias morinella of Boie, which should be called Morinellus anglorum, The European Turnstone should be Sérepsi/as marinus, the latter being the specific name given to it by Willoughby, Ray, and Catesby.

I found this species not uncommon at San Pedro, and on the rocky islands along the coast. Their food most probably consists of the Patelle and Chitons which so abound, and for obtaining which their bills are particularly adapted. When approached they utter a quick whistling Amit kwit, and when flying it is so rapidly repeated that it ends in a low trill. The plumage of the head, neck and breast is glossy blue-black, and of the back and wings glossy brownish-black The bill and fleshy ring round the eye bright vermillion : irids golden yellow : tarsus and toes fleshy, and almost white.

This noble species, so abundant on our southern coast, has for a long time been considered the S. cayana of Latham, notwithstanding its disparity with his description both in size and colouration. It seems to me that the Cayenne Tern must have been founded upon the immature plumage of one of the yellow-billed species of the Brazilian coast, since described by Lichenstein, probably the S. magnirostris. ' Young birds of our species would agree pretty well with the erythrorhyncha of Brazil, described by the Prince de Wied, as they are somewhat smaller and less proportioned, yet we hesitate to give it that name, until its identity can positively be proved, particularly as the Terns of that coast are peculiar.

XVII.—Additional Observations on a new living species of Hippopotamus. By Samvet Grorce Morton, M. D. Penn. & Edinb. In the year 18401 met with a man who had travelled extensively through the colony of Liberia, and beyond the limits of that province into the Dey and Bassa countries on the western coast of Africa. Among a variety of statements made by this person, was one to the effect that he had repeatedly seen, in the rivers of this interior region, a small Hippopotamus, not longer in the body than a middle-sized heifer, though possessing the relative proportions of the common Hippopotamus, to which it bore in all respects an epitomized resemblance. He further stated that the natives hunted this animal for food, and that he had himself seen it killed and eaten. This person’s account, and his replies to my questions, were clear and consistent throughout; but some subsequent circumstances tended to cast a doubt upon his veracity, and satisfied me that his statements required confirmation from other sources. In the summer of 1843, however, I received from my friend Dr. Goheen an extensive series of skulls of the mammiferous animals of Western Africa. They nad been obtained by him during a residence of several years at Monrovia, in Liberia, where he had officiated as Colonial Physician; a situation that gave him great facilities for procuring the natural productions of that region. Among these crania were two of a small Hippopotamus from the river St. Pauls; a stream that rises in the mountains of Guinea, and passing through the Dey country and Liberia, empties into the Atlantic to the north of Cape Messurado. Although nothing could be more manifest than the difference, both in size and conformation, between the head of this animal and that of the common Hippopotamus, I for some time hesitated to publish it, under the impression that so remarkable a species could not have wholly escaped the attention of zoologists. Having, however, carefully examined the latest Huropean works on Zoology without finding any notice of it, I at length published a description, accompanied with two wood engravings, in the Academy’s Proceedings for the month of February, 1844; and inasmuch as all subsequent investigation, both in Europe and this country, has confirmed the entire novelty of this species, I now republish it with some corrections, and much larger and more accurate illustrations. I first announced this animal by the name of Hippopotamus minor ; not knowing 59 232 DR. MORTON’S OBSERVATIONS ON at the time that Cuvier had already given this specific designation to a fossil species. It therefore becomes necessary to change it, which I do by placing this species in the zoological system by the name of HIPPOPOTAMUS (TETRAPROTODON) LIBERIENSIS.

This head is entire, excepting a small part of the nasal and maxillary bones of one side. The lower jaw is wanting. PI. 34, fig. 5. The other head is of the same size and proportions, but has pertained to a younger animal. It retains all the teeth, and for this reason I have used it exclusively in the following dental observations. It also retains the lower jaw ; but the occiput, orbit and zygome have been fractured, and parts of the bones lost. ‘There are also three slug or bullet wounds through the nasal region. PI. 32. Upper Jaw.—The central incisors are slightly flattened, and about a quarter of an inch in diameter at the alveolar margin. The lateral incisors are less flattened and more conical. All these teeth are slightly curved and nearly vertical. Pl. 34, fig. 3, and plate 33, fig. 3. The canines are about an inch in the longest diameter, and remarkable for a deep posterior groove or furrow, extending about half the depth of the tooth, and giving its cross section (and consequently the corresponding alveolus) a reniform outline. Pl. 34, fig.2. These teeth are much worn by attrition. False molars.—The first of this set is little more than an inch in length, slightly curved, and has but a single fang and point. PI. 33, fig. 5. The second and third false molars are very much larger than the first, with two fangs. They run to an irregular conical point, with a second rudimentary point on the posterior margin. The fourth false molar is less in size than the second and third, and is only partially A NEW LIVING SPECIES OF HIPPOPOTAMUS. 233 protruded above the jaw. It is capped on each side by the mere shell of the corres- ponding deciduous molar. ‘The latter has been removed in PI. 33, fig. 2, in order to show the protruding permanent tooth. The molars.—Of the three molar teeth the middle appears to be the largest; but the posterior one is so partially protruded as to render comparison imperfect. The crown of each, before it becomes worn by attrition, presents a double cone, divided into four points by a longitudinal fissure. The roots of the first two molar teeth are four in number, but the last has five. Lower Jaw.—In the lower maxilla dentition is complete, there being no remains of the deciduous teeth, and’all the teeth are perfect, excepting only in the molar fangs. The incisors.—These two teeth are much longer and more robust than those of the upper jaw. ‘They protrude nearly on a line with the alveolar margin, and are much worn away by attrition. Pl. 33, fig. 4. The canines differ from those of the upper jaw in being much longer, and in wanting the grooved or fluted character on their posterior surface. PI. 34, fig. 1. False molars—The first of these is smaller than the upper one. PI. 33, fig. 6. The second and third are more compressed than their fellows, and run up with - smooth sides to a flattened cone. PI. 33, fig. 7. The fourth false molar is a little smaller than those that precede it, and, like the corresponding teeth of the upper jaw, shows some resemblance toa true molar in its irregular crown and rudimentary points. PI. 33, fig. 8. The molars.—The three true molars increase in size from first to last, and differ in no material respect from the upper set. ‘The last of them, however, which has just attained its adult position, has four complete points on its crown, and a rudimentary one posteriorly. It has also five corresponding fangs, but these have not yet attained their full length. Pl. 33, fig. 9. Measurements.

It may be observed, however, that in the H. Leberiensis there is a slight but uniform convexity of the upper surface of the skull from orbit to orbit, and between the occipital and nasal bones ; while, on the contrary, in the H. amphibius the orbits are remarkably elevated, and the intermediate surface is concave. In my first description I committed an error in describing the orbit as nearly intermediate between the two extremes of the head. This mistake is corrected in the table of measurements. At the same time it is to be remarked, that the orbit is placed much nearer a central point than in the H. amphibius, as will be more particularly evident in the reduced vertical view, Pl. 34, fig. 5. The lachrymal bone in this species is remarkable for its extreme tenuity as well as forits form. It rises with prominent convexity from the floor of the orbit for nearly an inch in length, and is marked by a slight, sub-central, vertical constriction, that gives it a bilobed shape. Dr. Goheen, (who from the first of his seeing these bones, considered them indicative of a new species,) has obligingly favoured me with the following memorandum. ‘These animals abound in the river St. Pauls, and vary in weight from four hundred to seven hundred pounds.* They are slow and heavy in their motions, yet will sometimes stray two or three miles from the river, in which situation they are killed by the natives. They are extremely tenacious of life, and almost invulnerable excepting when shot or otherwise wounded in the heart. When injured they become irritable and dangerous, but are said by the natives never to attack them when in their canoes. The negroes are very fond of the flesh, which seems to be intermediate in flavor between beef and veal.” * Judging from the osteology of the animal, it can rarely attain this maximum weight. es eel ee a ee re oe | a a a a A NEW LIVING SPECIES OF HIPPOPOTAMUS. 235 In preparing to republish this animal, I had contemplated a review of the allied species both living and extinct; but before commencing the arrangement of my materials, I had the pleasure to receive a communication from Dr. Hugh Falconer, of London, the distinguished author of the Fauna Sivalensis. In this letter Dr. Falconer gives a clear and concise view of the present state of our knowledge of the several species, recent and fossil, of the genus Hippopotamus, and I trust I commit no infraction of the kindness and confidence of that gentlemen by inserting so much of his communication as refers to this subject. Lonvon, British Musevm, Ocroser 2d, 1847. “T regard your species as one of the most interesting and remarkable discoveries that has been made in recent zoology during the present century. Cuvier, in the “Discours Preliminaire,” has entered into an elaborate argument against the probability of any remarkable existing large species of land animal remaining to be discovered, after the search which has been made through the continents and great islands of the globe; but your discovery proves that the inference was premature. ”? The species as you have established it, is perfectly distinct from the H. amphibius. It differs more from the latter than H. amphibius does from H. major and H. paleindicus ; the only two fossil species of the same subgenus of which the crania are known. ‘The distinctive characters as you have given them, are very strongly marked, viz.: the length of cranium proper as compound with that of the face: the advanced position of the orbits: the convexity of the forehead, both from back to front, and across between the orbits: and the details of the dental character. The canine teeth of the upper jaw alone, without reference to the dimensions and other peculiarities, would establish the distinctness of the species. In H. amphibius and H. major, the internal vertical channel is shallow, while in your species it is so deeply grooved, as to yield a strongly marked reniform outline in the section. This character was of especial interest to me, as it is constant, and nearly to the same amount in an Indian fossil species, of the subgenus Hezaprotodon, var. Hipp. (Hez.) Stvalensis. Unluckily, Cuvier had preoccupied the specific name of H. minor for this small European fossil species, which he called both H. minor and H. minutus. 'The latter name is now generally applied to it ; but 1o prevent confusion, the name which you mention in your letter to me would be the most suitable to your species, and in the notice which I intend taking of it, I shall mention it as Hipp. Liberiensis, (Morton.) Enclosed I send you a synopsis of the results of my examination of the Hippopotamide, fossil and recent. 60 236 DR. MORTON’S OBSERVATIONS ON Hippopotamus comprises two subgenera, HexaProtopon, with six incisors above and below ; and TeTraproropon, the species with reduced incisors, viz., four above and below. Your species, although it has but two in the lower jaw, belongs to the latter subgenus. The excessive reduction is probably only an individual case of variety, but if proved to be constant, the position of species in the genus will not be altered. The succession of the species in the table indicates the order of their affinities. No. 1, H. major,is the most divergent form, with short cranium, posterior orbits, great elevation of the sagittal and occipital crests, and excessive elevation of the upper margin of the orbits above the plane of the brow. Next follows H. paleindicus, (No. 2,) a true fossil Hippopotamus from India. Then comes H. amphibius, No. 3 in the series, of which the French naturalists make two species, Capensis and Senegalensis. Duvernay, in a late memoir, (Comptes Rendus, October 1846,) maintains their distinctness, but I regard them as merely varieties. H. anmecteus, No. 4, is an undescribed fossil species from the Nile above the Cataracts, which I lately observed in the Frankfort ccllections, (the Senckenberg Museum,) and brought to Europe by Dr. Riippel in 1827. I have named it H. annecteus from its forming a link in size between H. amphibius and your species. ‘The cranium is not known. Cuvier’s H. medius has proved to be a species of Dugong, (Halitherium of authors.) Next follows Cuvier’s H. minor, No. 5, which is a doubtful Tetraprotodon. I range your. species last, from its close resemblance to the Indian Hezaprotodons in the form of the upper canines, No. 6. : Of Hexaproropon, we have three well-marked Indian fossil species. H. Iravaticus, No. 7, is asize larger than your H. Liberiensis. H. sivalensis, No. 8, is less than H. amphibius ; and H. namadicus, No. 9, with other strongly marked characters, is larger than H. amphibius, or the H. sivalensis. We possess portions of every part of the skeleton, showing the closest resemblance to Hippopotamus amphibius throughout, but more slender in the proportions. Merycopotamus is a most interesting and well marked genus, connecting Hippopotamus with Anthracotherium. 'The molar teeth, as in the latter, are constructed on the ruminant plan; while the cranium, incisors and canines, together with the leafy expansion of the angle of the lower jaw, connect it with the former.

India. , J eel dee In addition to the preceding remarks of Dr. Falconer, I submit the following in further explanation : The first attempt to divide the Hippopotamus amphibius of Linneus, was made by M. Desmoulins in Magendie’s Journal de Physiologie for 1825. This able naturalist, after comparing the head and parts of the skeleton of the Hippopotamus of Senegal with that of the Cape, came to the conclusion that the two animals were specifically distinct. On this subject I shall only remark, that I possess two adult heads from the Cape, and the Academy’s collections contain two others from Senegal; and that on comparing them, I find the Cape specimens to differ as much from each other as either of them does from those of the rivers of Senegal. If, however, they should prove distinct, the courtesies of science require that the specific name amphibius be retained for one of them, and to that of Senegal in preference, because it has been best known to naturalists, and has consequently served as the basis of most descriptions. In D’Orbigny’s Dictionnaire d’Historie Naturelle, M. Boitard has elaborately investigated this question. He details the two species proposed by M. Desmoulins, and adds that M. Lesson had proposed the name of H. Abyssenius for the animal inhabiting the upper Nile; but M. Boitard does not adopt these specific designations. This department of science has yet more recently been investigated by M. Duvernay, whose facts and conclusions are published in the Compte Rendu des Séances de l’Academie des Sciences, for October, 1846. It may suffice on the present occasion to observe, that M. Duvernay’s observations are favourable to the specific distinctions proposed by M. Desmoulins; he regards the Abyssinian animal as of the same species with that of Senegal, but maintains the specific distinctness 238 DR. MORTON’S OBSERVATIONS ON of the Hippopotamus of the Cape. He further admits the H. Liberiensis, (minor, ) to be- perfectly distinct from either, and concludes his memoir by adopting three species of living Hippopotami. Allthis is very well; but we confess our surprise that M. Duvernay, after confirming the two species proposed twenty years before by M. Desmoulins, should, without note or explanation, give new names to them both. Thus, he calls the Senegal and Abyssinian animal H. typus, because it has been jongest known to naturalists and others. The Cape species he designates H. australs. Now we must be allowed to repeat, that this unnecessary change of names is con- trary to the conventional usages of naturalists, and hostile to the utility and integrity of zoological nomenclature. For if M. Duvernay can be sustained in this mnovation, the very next writer on the subject has an equal right to indulge his fancy or ambition in the same way, and may discard M. Duvernay’s names for others of his own. Such practices tend to interminable confusion in science, which is already over-burthened with synonyma. In the present state of our knowledge, and awaiting the results of further observation and comparison, we can only admit of two living species of Hippopotamus as positively determined; viz. H. amphibius and H. Liberiensis. By the cruel munificence of the Roman Emperors, the solitudes of Europe, Asia and Africa were annually taxed to furnish wild animals for the bloody sports of the amphitheatre. Of all the large quadrupeds, the Hippopotamus was the only one that escaped the sacrifice ; not on account of his size, which would have been no obstacle, but from his amphibious habits, which prevented his being taken to Rome or exhibited in Europe. But the smaller species I now introduce to notice, is of so moderate a bulk, even in adult age, as to render his capture and transportation of comparatively easy accomplishment; and I feel confident that nothing more will be necessary to success, than an adequate reward to such of the inhabitants of Liberia as may be disposed to attempt so novel an enterprise. A half grown animal, if not really docile might at least prove tractable ; and by a studious adaptation of his food, and attention to his aquatic habits, we can see no great difficulty in introducing the Liberian Hippopotamus into the menageries of Europe and America. The skin and entire skeleton can no doubt be readily obtained, and would constitute most instructive additions to any collection of zoology or comparative anatomy. I shall close this paper by stating the remarkable fact, that although this Hippopotamus is abundant within one hundred and fifty miles of the sea coast of Liberia, the only parts of him that are known to have ever been sent from Africa, are the two skulls in my possession. I cannot find that any portion of the animal is yet contained in the museums of Europe.* * I sent my specimens to London by the hands of Mr. (now Sir Charles) Lyell, that they might be examined by those distinguished comparative anatomists, Professor Owen, of the Royal College of Surgeons, and Dr. Hugh Falconer, author of the Fauna Sivalensis.

This bird belongs to that group of species which forms the genus Coluspasser, Ruppel. From either of those species (V. flavoptera, Vieill., V. macrocerca, Licht., V. axillaris, A.

Three specimens of this interesting species, all of which are labelled as coming from Port Natal, by Mr. J. Verreaux, are included in the many valuable acquisitions of this Academy, made through the judicious exertions of Mr. Edward Wilson.

XX.—Cryptocephalinarum Boreali-americae diagnoses cum speciebus novis muset lecontiant. Auctore S. S. Hanpeman. An examination of the North American species of Cryptocephalus and Pachybrachis seems to indicate that the characters which are usually regarded as of generic value, are subject to considerable variation, and to some difficulty in the application. Several additional sections are here proposed, chiefly because the species cannot be placed in the former genera; but as it will be necessary to examine a much larger number of species, including both sexes, before this sub-family can be placed upon a permanent generic basis, several of the sections are allowed to remain in the old genus Cryptocephalus, instead of being provided with distinct names. The genus Chlamys would have been included in this paper, had it not been already monographed by Lacordaire in the second volume of his large work on the Phytophaga.

Tam under obligations to Dr. W. S. W. Ruschenberger, U. S. Navy, for the objects that are described in this note. On the late voyage of the U.S.ship Plymouth to China, while at no great distance from Rio Janeiro, a porpoise was captured by the seamen, in April 1848. Upon opening the animal she was found to be pregnant. The uterus and vagina, with a foetus thirteen inches in length, were preserved in alcohol, and upon Dr. R.’s late return to the United States, from Canton, they were presented to me. Professor Agassiz, at that time in the city, was invited to examine the specimens with me, and the observations then made were so remarkable, that that gentleman considers them well deserving of being laid before the Academy. I now submit for the inspection of the members, both the original specimens an | . several drawings of them, The womb is two-horned, and still contains the whole of the chorion. It is a very strong muscular uterus, divided by a thick partition. The cervix uteri appears to me to be not much deployed, and is still a thick and very strong cylinder, terminating by a well formed vaginal cervix, and os tince, that projects about three-fourths of an inch into the uterine extremity of the vagina. The mucous membrane of the vaginal cervix 1s formed into regular ruge or plice, that passing inwards to the os uteri go upwards into the canal of the cervix. The os uteri is a transverse sulcus asin the human uterus. Vide Pl. XXXVI. fig. 2, and PL XXXYV. fig. 1. The vagina is about two inches and a quarter in length—in its present state. It is condensed and contracted by the alcohol, in which the specimen has been preserved for nearly a year, The specimen and the drawing show the arrangement of the ruge of the vagina. Pl. XXXV. fig. 1, e. Upon opening the vaginal cervix by an incision carried from the os upwards, we were surprised by finding a second os tince and cervix, similar to the former one. The drawing shows, better than any description, the arrangement of this singular apparatus, and I submit to the members, this original specimen, in which the second or upper cervix and os are seen to be enclosed in the canal of the cervix, as the lower one is encased in the canal of the vagina. It will be seen upon comparing them, that the drawing gives a faithful representation of the facts. Pl. XXXVI. fig. 2, a, b, d. 68 268 MEIGS’ OBSERVATIONS ON THE REPRODUCTIVE ORGANS, The foetus was developed in the left cornu of the womb, the right one being partially developed by the intrusion into its cavity of the chorion and allantois. The foetus, as I have said, is thirteen inches in length, and must have floated free in the waters of the amnios. Such an inference is deducible from the fact that the animal is not permanently flexed ; as in the terrestial mammals. Pl. XXXV. fig. 1. I am ignorant of the length of the uterus previous to the discharge of the ovum. Doubtless it must have contracted very much after it was opened. In its present contracted state, the womb is eleven inches long, by eight inches in its conjugate diameter. The walls are about one-third of an inch thick. Pl. XXXVI. fig. 1. The whole interior aspect of the womb is pleated or folded like irregular valvule conniventes ; and these plice, being very strongly expressed, and innumerable, have the effect of augmenting the superficial contents of the inner aspect of the womb two or three hundred per cent. beyond that of the external surface. Iam not sure that the inner aspect is not four or five hundred per cent. above the outer aspect in superficial quantity. The specimen, which I now exhibit, may serve to satisfy those members who may choose to make the computation. The drawing represents these pleats or folds ; (PI. XXXVI. fig. 1, d, d.) and I have also here, a drawing representing a section, magnified five diameters, to show the multiplication of superficies thus obtained. I have said that the foetus was developed in the left cornu, and that there was but one foetus ; nevertheless its allantois carried the chorion into the right cornu also, which was very considerably developed by the distending chorion and amnion, serving in this manner, greatly te multiply the points of contact betwixt the chorion and the maternal surface. Pl. XXXVI. fig. 1, b, d. The chorion, whose inner surface is smooth, and even polished, is upon its exterior aspect pleated in such manner as to let its projections and sulci fit accurately the corresponding sulci and projections of the uterine folds ; so that—if in the present specimen, the womb, before it was opened, was fourteen inches in length within—the chorion was also fourteen inches in its longest diameter: but, if the inner aspect of the uterus was greatly multiplied in its superficies, the outer aspect of the chorion was equally multiplied. Hence the surfaces of contact of the foetal organ with the mother’s womb exceeded by many hundred per cent. the apparent surface of contact. As to the amnios and the allantois, they were removed with the fcetus, and given to me already separated, and so much broken and torn that 1 shall not venture to describe them now. I here exhibit them, however, to the members, who may perceive that they cannot be fitly described in this note. Pl. XX XV. fig. 1. It appears to me that the structures thus briefly described are worthy of consideration, as disclosing a most remarkable adaptation of the organs to the nature AND ON THE FETUS OF THE DELPHINUS NESARNAK. 269 and condition of the cetaceous parent or dam; andI shall venture to offer some remarks upon their economical uses or purposes. I believe the observation is new in comparative anatomy and embryology. In gestation of the mammifera, the womb expands under a compulsion derived from the augmenting magnitude of the ovum ; which, like an acephalocyst, imbibes the materials or plasma from its placental disc or discs. There is a constant tendency of the fundus and corpus uteri to resist their extension, and an equally constant effort of the cervix and os uteri to retain the ovum within the womb. The progress of a gestation brings that contest to a close by developing the cone of the cervix, and changing it into a cylinder that can no longer counteract the expulsive effort of the fundus. The last conflict is labor, in which the foetus is expelled. Thus there is in the gravid womb a facultas retentrix and a facultas expultrix, that are in constant antagonism. In the terrestial mammals these forces are balanced according to the genus of the animal, which lives under an ordinary atmospheric pressure of fifteen pounds to the inch. Mr. Scoresby in his Account of the Arctic Regions, &c., vol. 2, p. 249, computes _ the surface of a large whale at 1540 square feet, and he has a foot-note of which the following is a copy. “From experiments made with sea-water taken up near Spitzbergen, I find that thirty-five cubical feet weigh a ton. Now, supposing a whale to descend to the depth of 800 fathoms, or 4800 feet, which, I believe, is not uncommon, we have only to divide 4800 feet, the length of the column of water pressing upon the whale, by 35 feet, the length of a column of sea-water a foot square weighing a ton, the quotient 137: shows the pressure per square foot upon the whale in tons, which, multiplied by 1540, the number of square feet of surface exposed by the animal, affords a product of 211,200 tons, besides the usual pressure of the atmosphere.”’ Mr. S. says that we can have but an imperfect conception of such a degree of pressure, which exceeds in weight, sixty of the largest ships in the British navy, when manned and provisioned and fitted for a six months’ cruise. Is it not a remarkable thing that the mammiferous cetacea, when launched in the ocean, to be subjected to such inconceivable pressure, should be provided against one of the greatest hazards to which their state as marine mammals could expose them ? Seeing the perpetual antagonism of the facultas expultrix and the facultas retentrix in ordinary gestation, it could not happen that the parent should plunge to the depth of even four or five hundred fathoms without losing the fruit of the womb. Let it be stated that in any case, as in our specimen, the superficies of the gravid womb is one hundred inches, of which the os uteri has one inch and the rest of the 270 MEIGS’ OBSERVATIONS ON THE REPRODUCTIVE ORGANS, organ ninety-nine inches. Then ata depth of 800 fathoms the sea pressure per square inch, or that on the os uteri, is equal to 2055 pounds, while the sea pressure on the remaining 99 inches equals 203,445 pounds. So great a reinforcement to the facultas expultrix would inevitably overcome the resistance of a single or simple os uteri. Hence, to obviate a great risk of losing the genera by the destruction of the embryons, the facultas retentrix has been fortified and made secure by an apparatus not in use in any terrestial mammal. I should think no man need look for a more absolute demonstration of a plan or plans of creation. But I have to remark that the exterior surface of the chorion in this mammal is converted into a placenta, in which respect it resembles the placenta of the pachyderms, as the mare and hog, in which the whole exterior surface of the chorion becomes placenta ; while in the carnivora it is zoniform, and in ruminants consists of numerous placentules. In this cetacean, not only is the exterior surface of the chorion become a fleshy and vascular process, but the surface is immensely multiplied in order greatly to increase the surface of contact and the chances of eration. For some of the cetacea make plunges that last for thirty minutes, before they return to the surface to breathe. “The average stay under water,” says Mr. Scoresby, ‘‘of a wounded whale, which steadily descends after being struck, according to the most usual conduct of the animal, is about thirty minutes; but in shallow water, I have been informed, it has been sometimes known to remain an hour and a half at the bottom after being struck, and yet has returned to the surface alive.” —Op. cit. p. 247. Now, inasmuch as the foetal cetacean depends for its eration upon the branchial offices of its placenta, does it not appear that such protracted absence from the surface as thirty minutes, would suffice nearly to asphyxiate the dam, and certainly, to destroy the fruit of the womb, but for the vast multiplication of the erating surface that I have described and figured in the present specimens? With so extensive a superficies of erating or oxygenating branchia or placenta, the foetus might survive after the most protracted absence from the surface that the dam might be induced to suffer. Another proof of the wisdom and foreknowledge and plan of the Author of nature. To know that plan; to look through nature, up to nature’s God, ought to be the highest aim of the naturalist and the physiologist. It might be interesting to the members to observe the mode of connection between the chorion or placenta and the womb. In separating these surfaces by the avulsion of the chorion, it is manifest that no vascular tractus is broken; and I cannot AND ON THE FCETUS OF THE DELPHINUS NESARNAK. 271 conceive that any one could inspect this process of separation without resting in the absolute conviction that the union is not anatomical, but only, and merely, one of contaction. Such is the case clearly in this genus: probably the same law prevails as to the Balenas, and, indeed, as to all the cetaceans. The young mysticete, at birth, is from ten to twenty feet in length. Ifsuch a vast foetus can be developed in utero, without the aid of the maternal placenta, as it is called, we have a fair inference as to the non-existence of such an apparatus in the other genera; and particularly in the human organ, where the average weight of the foetus at term is only seven pounds. I avail myself of the present oécasion to make this statement, because it confirms the views I have already expressed in my publications on the subject of the placenta. The foetus, which I now exhibit to the members, is perhaps not a sufficiently developed creature to warrant me in deciding upon the species of its dam, Nevertheless, after comparing it with all the specimens to which I have had access, I cannot but think it belongs to the species Delphinus Nesarnak. The appearance of the skin of the dam and that of the foetus; the form of the muzzle or snout, so similar to that of a duck; the black termination of the jaws ina well formed bill,—all lead me to conclude the species to be that of the Delphinus Nesarnak, of Lacepéde’s Histoire des Cétacés—and this notwithstanding the Nesarnak is an Arctic porpoise, while the specimen was taken near Rio de Janeiro. The drawing of the foetus seems to me very faithfully to represent its magnitude and form. The animal has nearly the stomach of a ruminant, i.e.,it has three distinct cavities, not four. The paunch is absent but the bonnet and the many-plus, with the abomasum or red, are very similar to the ruminant stomach. Pl. XX XV. fig. 2. The intestinal tube is very small. It has no cecum and no colon. Such an animal living in the water has no occasion for a cecum or colon, since the dejection of the residue of its aliment would occasion no inconvenience. An enormous cecum would occupy too much of the internal cavity, which is required for the purposes of the respiration. Hence the abdominal cavity is exceedingly small; whereas the cavity of the thorax is vast, as fitting it to accommodate the enormous lungs required to endow the blood with oxygen during the plunges of the animal. I annex a drawing of the stomach and alimentary canal which may be compared with the specimens. Vid. Pl. XX XV. fig. 2. I present a specimen and drawing to show the arrangement of the larynx. Vid.

XXIII.—Revision of the North American Tailed-Batrachia, with descriptions of new genera and species. By Spencer F. Bairp, Carlisle, Pennsylvania. The following notes, introductory to a more detailed memoir on the same subject, will, it is hoped, throw some light upon this obscure portion of American zoology. To this we would refer for the descriptions of species, with their anatomical and physiological characters, giving only in this place brief outlines of the genera and the synonymy of the species. It is probable that reference to some, hitherto inaccessible, records will change the specific nomenclature to a certain extent; this, however, can affect only a few. No synonyms or references are quoted, but such as are based (as far as known) upon original descriptions, mere quotations from the previous descriptions of others being omitted. BATRACHIA URODELA, Dum.° GROUP I. ATRETODERA, Dum. et Bib. Branchial apertures obliterated at maturity. Section 1. Sphenotdal teeth absent. Carpus and tarsus ossified in the adults. Ampystoma, T'sch. Vomerine teeth in an undulating transverse row, composed of several curves varying with the species. Tongue broad, fleshy, filling interspace of rami ; entirely attached except at the lateral and anterior edges, where it is slightly free. Carpus, tarsus, and basi hyal ossified in extreme adults. Body very stout and clumsy. Skin in some species, with close set glands, secreting a milky fluid. « Tail sub-round. ‘Toes rather long and slender, cylindrical or conical. s- ‘Tail compressed. ‘Toes short, broad, sub-palmate. NotopruaLmus, Raf. ‘Tongue rudimentary; the end of the hyoid apparatus appearing in the mouth as asimple knob. Vomerine teeth forming an acute V in the palate; the vertex between the posterior nares, the branches much prolonged backwards. A bony orbit above the eye, formed by the union of processes from the frontal and tympanic bones, enclosing a foramen through which pass flexor muscles of jaw. Similar in this respect to Cynops, Tsch., Pleurodeles, Waltl., and Euproctus, 282 BAIRD’S REVISION OF THE Gené. Ossification extending to hyoid apparatus, carpus and tarsus. Vertebra much compressed, with high crests. ‘Three apertures in the skin of the cheeks, behind the eye, not communicating with the cavity of the mouth. Hind feet much flattened; first and fifth hind toes nearly rudimentary. Section 2. Sphenordal teeth absent. Carpus and tarsus not ossified in the adults, Sub-section 1. Tongue entirely attached as in Ambystoma. Pietuopon, Tsch. Sphenoidal teeth on two tangent plates attached to the sphenoidal bone. Skin glandular, exuding a milky fluid. Tail cylindrical.

Sphenoidal teeth in two narrow patches, attached to the edges of the sphenoidal bone. Occipital condyles very peculiar in consisting of short cylinders projecting from the ex-occipitals, with their axes parallel to that of cranium, and their extremities forming a spherically convex articulating surface. Crest of first cervical vertebra transverse, with a strong ligament passing from each end, across the posterior corner of the cranium, to be inserted into the lower jaw. These ligaments prevent the opening of the jaws beyond a very slight amount. Eggs (in the second species) wrapped round the body of the female, who remains in a damp spot until they are hatched. Hemipacrytium, Tschudi. Toes, four on the hind feet. Sphenoidal teeth in two broad short patches. Skin somewhat granular. Costal furrows more deeply impressed than common, extending to dorsal line. Tail narrower at the base than near the middle. Sub-section 3. Tongue entirely protractile, capable of considerable protrusion, circular in shape, and supported on the tip of the constricted hyoid apparatus. Oevipus, (Tschud.) Body stouter than in Plethodon glutinosus. -Sphenoidal teeth on two plates, not in contact ; diverging behind. ‘Toes dilated at the tips into sucker like disks as in Hyla. Pseuporriron, Tsch. Sphenoidal teeth much the same as in Oedipus, and the _ other genera of this sub-section. Body very stout, less so than in Ambystoma punctata. ‘Tail equal to or less than the body. Breadth of scull about equal to the length. NORTH AMERICAN TAILED-BATRACHIA. 283 SpPELERPES, Raf. Body very slender. Tail as long or longer than the body. In some species a cirrhoid apparatus projecting ftom the edge of the upper lip, below the nostril. BatracuHoseps, Bon. Characters much like the last. Toes four on the hind feet.

It is only because there is no positive proof to the contrary, that I retain the genus Siredon as real, placing itat the bottom of the series. It so much resembles the larva of Ambystoma punctata, in both external form and internal structure, that I cannot but believe it to be the larva of some gigantic species of this genus. It differs from all known perennibranchiates in possessing the larval character of the gular or opercular flap, this being unattached to the subjacent integument and free to the extremity of the chin. The non-discovery of the adult is no argument against its existence; I had caught hundreds of the very remarkable larva of Pseedotriton salmoneus near Carlisle before I found an adult. Until then I knew not where to refer the animal, supposing this species to exist no nearer to me than the mountains of northern New York and Vermont. Descriptions of four new species of North American Salamanders, and one new species of Scink. AmBystoma MacropacTyLa, Baird. Scull longer than broad. Toes long, unwebbed. A broad dorsal reddish brown stripe. Beneath dark brown, unspotted. Specimens in the Academy of Natural Sciences of Philadelphia. Brought from Astoria, Oregon, by J. K. Townsend, M. D. Body rather more slender than in the other species of Ambystoma ; the proportions nearly those of Desmognathus fuscus, (Raf.) The colors somewhat like those of a badly preserved Plethodon erythronotus, (Green.) Ground color dark brown. A broad dorsal stripe, originally, it is probable, of a chestnut brown color, now very obscure. Sides sprinkled with greyish. The brown of the sides becomes more concentrated towards the vertebral line. ‘Tail sub-round, not compressed. Largest specimen about 23 inches. From the snout to the insertion of the hind legs 1} inches. AmMBYsToMA MavorTIA, Baird. Scull broader than long. Toes short and broad. NORTH AMERICAN TAILED-BATRACHIA, ETC. 293 Tail much compressed. Color dark brown, with several large yellowish blotches beneath, and transverse bands of the same on sides of body and tail. One specimen procured in New Mexico by Dr. Wislizenus while attached to Col. Doniphan’s expedition. Body thick and clumsy, more so than in Ambystoma punctata. Feet short; toes broad. ‘Tail slightly ensiform ; longer than the head and body. General color (as preserved in spirits) a dull black or dark brown, with two or three yellowish blotches occupying the greater part of the belly. About nine broad transverse bands of yellowish on the sides of the body, confluent to a certain extent with that on the belly. Similar markings on the tail, forming nearly complete ellipses, and about twelve in number. ‘The back is not crossed by the yellowish, but is rather darker than the ground color. The interspaces of the transverse yellowish markings are confluent with the dark brown on the back. Extremities blotched like the body. ‘Total length eight inches. This species comes nearest to Triton ensalus, Esch., it differs from it in color, and in the arrangement of the palatine teeth. AmBystoma EpIscopus, Baird. Head wedge shaped. Scull longer than broad. Tail much compressed, shorter than the body. Body yellowish with dark mottlings and darker spots. One specimen sent by Clinton Lloyd, Esq., from Kemper County, Mississippi. Froportions of body nearly those of Ambystoma opaca, Grav, The specimen much corrugated, and its colors obscured by alcohol. The general color appears to have been a shade of yellowish over the whole body, obscured on the back by very minute dusky mottlings. ‘This mottling less evident on the feet and tail; abdomen and tail beneath almost entirely free from it. Head, back, and sides of the tail with numerous spots of a darker mottling than that just described. These are sub-circular distributed rather uniformly on the head and body; they are larger, and more irregular on the sides of the tail ; their average size is that of the iris. On the sides, between the fore and hind legs, the dark mottling is concentrated into an obscure broad dark band. Length about five inches. Psevporriron monraNnus, Baird. Similar to P. ruber, (Daud.) Tail as long as the body. Iris dark, without the longitudinal bar. Two specimens obtained in the South Mountain, near Carlisle, Pennsylvania. Ground color of all the upper parts reddish brown, with sparse circular spots of well defined black or dark brown. Beneath deep salmon color: spots few on the sides and the outside of the limbs. 294 BAIRD’S REVISION OF THE NORTH AMERICAN TAILED-BATRACHIA, ETC. Iris dark chestnut brown almost black, with faint mottlings of bronze on the inner border, and without the dark bar of P. ruber. In this latter species the iris is brassy yellow with a dark longitudinal bar. Proportions of body most like those of P. salmonea, (Storer) 'The insertion of the hind legs is just half way between the snout and tip of tail. In P. ruber it is considerably nearer the tail, which thus becomes shorter than the head and body. The crown of the head is more elevated, and the occiput more convex in P. montanus than in P. ruber, the scull also is more elongated. The spots on P. ruber are more numerous, and generally not so well defined. When also the ground color in P. ruber is darker than the usual rich salmon color, the spots are very much crowded, indistinct, and confluent with the ground tint. Costal furrows in P. montanus 17; but 16 in P. ruber. Of the two specimens obtained, one was six inches long, the other three. The latter was even more characteristically marked than the former. Both were described when living. PLESTIODON ANTHRACINUS, Baird. Size between Lygosoma lateralis and Plestiodon fasciatus, without any indication of a vertebral line. Four narrow longitudinal yellow lines, and on each side a bread stripe of anthracite black. Upper parts dark bronze ; each scale has a faint border of this color, with a central cloud of the same. Small blotches on the plates of the head. ‘The lateral band of black begins at the nostril in a sharp point, passes back including the eyelids and widening to the ear; after this it continues parallel to beyond the vent, when it tapers to the end of the tail. The tint of the black is that of highly polished anthracite coa’. On each side of this lateral anthracite band*is a narrow stripe of pale yellow, the upper passing through the middle of one row of scales, the lower including the contiguous edges of the rows. The remainder of the row of scales above the upper yellow stripe is also anthracite, with which color the sides immediately below the lower stripe are also tinged. Beneath yellowish white. Under the microscope each lower scale exhibits a finely dotted reticulation. Tail dark blue above, beneath lighter. Outside of legs and feet black like the sides, inside lighter. Iris black. In a single very old specimen the whole head to behind fore legs was tinged with the red color found in almost all of the Plestiodontes. Measurements of a specimen of medium size. Total length 54 inches; tail from vent 34; head to ear 3; breadth of head 4; greatest breadth of dorsal band ;, ; ‘of lateral band 3. Found quite abundantly about old logs, in the North Mountain near Carlisle, Pennsylvania. More plentiful than either Plestiodon fasciatus, or P. quinquelineatus. ART.

Under parts slightly tinged with fulvous or buff. Breast, flanks and thighs with the bands narrower, and the throat with a more decided brown collar. A few superciliary feathers white, tipped with brown. Back and wing coverts with ferruginous and white spots. Upper tail coverts with the white spots more numerous, Total length (of skin) from tip of bill to end of tail about 14 inches, wing 63, tail 6 inches. Hab. Jalapa, Mexico. This species resembles some stages of plumage of the M. xanthotheraz, (Cuv.) and the M. leucauchen, (Temm.) PI. col. 92, 306. It may readily be distinguished from either of those by the absence of the handsome rufous chestnut color of the breast and back, which prevails in all the specimens I have seen of them, and also by the broader and much lesser number of the bands upon the feathers of the under surface of the body. *From “ Catalogue of Birds collected by Mr. William S.

Head above, chin and throat, crimson, which color ends in a point upon the breast. Head crested. A broad stripe from the base of the bill through the eye to the ear, glossy black. This stripe completely separates the crimson of the upper part of the head from that of the throat. Upper surface of the body, wings and tail, cinereous black. Entire under parts (from the breast) white. Legs (in skin) nearly black. Total length (of skin) from tip of bill to end of tail about 62 inches, wing 3 1-10, tail 2 8-10 inches. Hab. Rio Negro, South America. This bird has the same general appearance as Tanagra gularis, Linn., and T. capitata, D’Orbigny. From either of those species it may at once be distinguished by its black nares and ears, and also by its having the throat and point upon the oreast of the same crimson exactly as the crest, without the slightest appearance of the purple into which the crimson changes upon the breast in both the species mentioned. . Several specimens of this curious species have been sent from Europe by Mr. Edward Wilson, to whose remarkably valuable additions to the collections of this Academy, I have so frequeritly had occasion to allude. I have seen several other specimens brought from the Rio Negro, in a collection made by a gentleman formerly resident at Para. * From Proceedings Acad. Nat.

XX V.—New species of Myttonates from the Eocene of South Carolina, nith other genera not heretofore observed in the United States. By Roperr W. Gissses, M. D., Correspondent of the Academy of Natural Sciences of Philadelphia, &c. The family of Placoid fishes is found in abundance in the Tertiary formations. In those deposits of South Carolina their teeth are particularly numerous, though usually much broken. Among the Squalde I have identified and described (with those here noticed) ten genera and forty-five species ;—of Przstis I have published a new species, and of Mylhobates I have numerous fragments. Two species are distinctly represented by specimens now noticed and figured. Of the genus Mylobdates, Muller and Henlé recognise five recent, while Professor Agassiz has described fifteen fossil species, chiefly from the London clay. This genus is characterized by broad transverse teeth ona flat plate, bounded laterally by three rows of narrow hexagonal teeth of equal length, united by fine sutures. ‘The arrangement resembles that of a tessellated pavement. The specimen figured PI. 42, figs. 1, 2, 3, has some resemblance to M. micropleurus, Agassiz, but the lateral edges of the large transverse dental plates are more unequal, as well as the form of the small ones, and the sutures are more curved backwards. There is also perceptible a slight longitudinal flattening traversing the median line, and it is more arched laterally. The lateral plates are too much broken for description. The plates on the inner surface, Pl. 42, fig. 2, are very regular, and on the suture surface, Pl. 42, fig. 3, are grooved in the form of a compressed V. It was found in the Eocene marl of Ashley river, South Carolina, and was presented to me several years since by Mr. F. S. Holmes of Charleston, whose name I attach to it, Mytiopates Holmesii. The second species, Pl. 42, fig. 4, was found in the Buhrstone (Eocene) formation in the neighborhood of Orangeburg, South Carolina. It is more regular in the form of the dental plates, which are less curved; the surface is more convex and flattened by abrasion on the anterior third. It corresponds with no described species. It is very common, as I have many fragments from various localities. The plates being nearly straight it may be designated Myiopares transversal. Prycuopus poLyeyrus, Agassiz. Five years ago I received from a friend a specimen of Ptychodus polygyrus, (Pl. 42, figs. 5, 6,) supposed to be from Alabama. Lately Dr. Ames of Montgomery, Alabama, kindly forwarded to me another from the Cretaceous of Alabama, (PI. 42, fig. 5a,) which fixes the origin of the former individual. 76 300 GIBBES’ NEW SPECIES OF MYLIOBATES, ETC. PLATAX, Agassiz. A singular bone has been sent to me from the Pliocene marl of Darlington, South Carolina, which Professor Agassiz considers the interapophyseal bone that supports the dorsal spines of Plataz—a genus of Ctenoid fishes still existing in our present seas. Several views of a specimen are here given, Pl. 42, figs. 11, 12, 13. SQUALIDA. CARCHARIAS. In my monograph of the Fossil Squalide of the United States, I mentioned having met with a fragment of what I considered a Carcharias. I have recently found among some specimens from the Eocene of Ashley river, one of which is figured in P].42, fig. 8. Professor Agassiz agrees with me that it is a true Carcharias. It resembles that described by him as C. tenuis. Until others are found I am unable to decide upon its specific characters. CARCHARODON. C. LEPropon, Agassiz. I have recently identified this species from the Eocene of Orangeburg, South Carolina, PI. 42, figs. 7,9. It has the form of the variety of C. angustidens, figured by Professor Agassiz as C. heterodon, though it is more slender and acutely pointed. ‘The absence of the lateral denticles and the slenderness are its specific characters. ‘The serratures appear also to be more minute. GALEOCERDO. ~ The figure PI. 42, fig, 10, represents a symphyseal tooth of a species of Galeocerdo. I have not seen the specimen, but am indebted to Capt. A. H. Bowman of the Topographical Engineers, U.S. A., for a drawing of it, found in the Focene sand of Ashley river near Charleston, South Carolina. REFERENCE TO PLATE XLII. Figs. 1,2.

XX VI.—Descriptions of two species of Distoma with the partial histery of one of them. (Plate 43.) By Josep Letpy, M. D. One of the most remarkable divisions of organized nature, and that which probably more than all others has at once excited the wonder, disgust, and horror of mankind, is the class of animals known as Entozoa. Their habitation, frequency of occurrence and numbers, and their often terrific appearance, are sufficient reasons to have given rise to such feelings. From the great variety and singularity of their form, their habits, and the mystery in which their origin and progressive development has always been involved, they have ever caused naturalists to attach peculiar interest to them, and they have been studied with a patience and zeal which has not been excelled in any other branch of human learning. In the term Entozoa has been included many animals of very different zoological characters, but in the present state of our knowledge, the general distinction founded upon the character of their habitation is probably as good a classification as can be adopted. We are often astonished at the extent of ecto-vitality : at the idea of a drop of water from any stagnant pool containing as many living bodies as there are human beings on the globe, etc., yet when we consider closely ecto-vitality, we will probably be no less astonished at its extent. Thus, when we reflect upon the moving mass containing millions upon millions of Bodo, in the large intestine of the toad, frog, salamander, in the intestine of the house-fly, &c.; the innumerable hosts of monads, vibrios, &c., in the intestinal and other fluids of most animals; the infinity of spermatozoids ; the numerous Gregarine in the ventriculus of insects we may suspect internal and external life almost to be in equilibrio in their extent. But it is not only the lowest forms of entozoa which are so numerous : I have removed fifty-six specimens of Dzstoma from the pericardial cavity of a snail; I have preserved over six hundred specimens averaging the one-tenth of an inch in length of a nematoid worm which I took out of the abdominal cavity of two individuals of Passalus cornutus ; froma single Jilus marginatus I obtained 140 specimens of Gregarina, 78 of an Ascaris, 27 of another nematoid which I have named Aorwrus, over 1000 of Nyctotherus, besides innumerable monads, vibrios, and entophytes. My friend Dr. J. L, LeConte informed me he had seen a pint of Ascarides taken from the intestinal canal of a Boa constrictor. I found at one time fragments of 80 specimens, averaging 302 LEIDY’S DESCRIPTIONS OF DISTOMA. five inches in length, of Tenia canina, in the intestine of a small terrier dog, and Krause mentions an instance of a two and a half year old horse, which contained over 519 Ascaris megalocephala, 191 Oxyuris curvula, 214 Strongylus armatus, var. major, 69 Tania perfoliata, several thousand Strongylus tetracanthus in the intestines, 287 Filaria papillosa in the thoracic and abdominal cavities, and 6 Cysticercus fistularis upon the peritoneal covering of the liver.* Numerous other instances might be given to demonstrate the extent of entozoic vitality, but those I have mentioned will suffice. All animals under certain circumstances become the residences of entozoa, and these appear to be most frequently presented as we descend in the scale of organic activity of animal life. Entozoa are most frequent among invertebrata, next among fishes, then reptiles, and least so among birds and mammalia. My much respected friend, Dr. Samuel Jackson, Professor in the University of Pennsylvania, entertains the opinion, as animals descend in the series, and higher ones undergo a degradation of structure, as in disease, they become more liable to entozoic life, and he has mentioned to me the fact, that the well-fed and nutritioned inmates of our hospitals, in post mortem examinations, seldom present the existence of intestinal worms, when compared with the accounts of post mortem examinations of the hospitals of continental Europe. In connection with this opinion arises the question whether entozoa are the cause or effect of disease. From my observations I am inclined to believe, with the distinguished helminthologist Dujardin, that they are usually the effect of disease, as is expressed in the preface to his excellent work entitled “ Hist. nat. des Helminthes.”’+ ‘D’aprés cela, on peut se demander si les helminthes sont véritablement nuisib'es aux animaux dans lesquels ils habitent? je suis pour la négative, tant j’ai vu d’exemples d’animaux bien portants qui contenaient plus @helminthes que d’antres individus de chétive apparence: les helminthes se développent dans un’site qui leur convient, sans nuire plus que les lichens sur l’écorce d’un arbre vigoureux. Ils ne peuvent devenir nuisible, généralement, que par suite d’ une multiplication excessive, laquelle semble alors étre une des conséquences d’un affaiblissement provenant d’une tout autre cause, d’une mauvaise alimentation, du séjour dans un lieu froid et humide, etc.; sans cela, les helminthes naissent et meurent dans le corps de leurs hdtes, et peuvent paraitre et disparaitre alternativement sans inconvénients.” After these general remarks upon Entozoa, I present to the Academy descriptions of two species of Distoma, which I suppose to be new, with the partial history of one of them. * Guilt u.

Long. 2} lin.; lat. 1-27 unc. Parasiticum in Boa constrictore, in pelve et uretere renis. Body white, posteriorly variegated with brown arising from the ova along the tortuous and folded oviduct, spathiform, narrowing from behind forwards, furnished with minute spinous appendages arranged in circles around the body, of which there are in the neighbourhood of 200 ; leneth of spines 1-1142d in. Oral acetabulum globular, placed just posterior to the anterior apex of the body, 1-107th in. in diameter. Oral orifice large and round when expanded, 1-160th in. across. Pharynx broad, 1-320th in. long. Oesophageal bulb oblong, 1-123d in. broad. Oesophagus 1-114th in. long, dividing into two long straight intestinal branches,:.which are dilated or clavate posteriorly. Ventral acetabulum round, a very little larger than the anterior, with the appearance of a transverse opening, 1-100th in. in diameter. Generative orifice just anterior to the ventral acetabulum. Penis exserted, curved, cylindrical, 1-63d in. long; an apparent second portion, rather longer and with a sigmoid curve, is contained in a sheath, at the posterior part of which the vas deferens is connected. Testes four in number usually globular and distant: the first or most posterior is 1-80th in. in diameter, the second 1-97th in., the third is subreniform, and is in contact with the last and is 1-160th in ; the fourth is 1-89th in. Ovaries two, lateral and anterior to the testes, white, about 1-35th in. long, each consisting of ten to thirteen oval or rounded lobes, connected together by a delicate tube ; the two joined by a transverse duct which opens into a very long sinuous and folded oviduct, occupying the posterior two-thirds of the body.

Dimensions.—Greatest length 22 lines; shortest 1} lines; greatest breadth posteriorly 1-20th in., anteriorly on a line with the penis 1-33d in. Habitation and:\Remarks.—Of this species of Distoma I found twenty-six specimens in the ureters and pelves of the kidneys of a Boa constrictor, which died in the menagerie in this city. They were not contained in cysts, but were loose, and were enveloped in mucous, probably the result of irritation produced by the spinous appendages of the entozoon. The spinous appendages exist from the oral acetabu- lum to the posterior extremity of the body, and are arranged in transverse annuli around the latter, which give the body itself the appearance of being annulated. It 77 304 LEIDY’S DESCRIPTIONS OF DISTOMA. is probable these appendages.served in some measure to retain the animal in its appa- rently precarious position. The movements of the Distoma were rather sluggish, shortening and elongating. The oral orifice frequently dilated to such an extent as to make the acetabulum appear like a cup. In the contraction of the animal, the intestinal rami, from their comparative shortness did not become sinuous. This species belongs to the second subgenus, Dicrocalium of Dujardin, characterized by “the intestine having two simple branches prolonged backward, and preceded by a simple moderately long oesophagus; anterior disk naked or without spines or lobes ; ventral disk sessile ;”’ first section :—‘“ testicles situated behind the ventral disk before or among the folds of the oviduct.”’* It approaches most to Distoma assula,t but this has only two testes ; the posterior coloring, the form of the body, and extent of the spinous appendages also differ. It is not more than one third or one half the size of Distoma naja.t Disroma vacans. D. Helicis, Proc.

Long. 1-26 unc.; lat. 1-42 unc. Parasiticum in Helice alternata et H. albolabre, in pericardio, etc. The Distoma vagans I have found in three stages of its existence in Helix alternata and Jf. albolabris. In some one of these stages it is almost constantly found in the former species of Helz. In none of them at any time can the slightest trace of a generative apparatus be found, so that the animal no doubt undergoes further development in some other animal. From an aperture, which is visible in the second and third stages, posterior to the ventral acetabulum, I suspect the species belongs to the subgenus Brachylaimus, Duj., “intestine divided immediately behind the ceso- phageal bulb;” second section :—“ male genital orifice behind the ventral acetabulum, towards the middle of the posterior part of the body.’’§ Description of the first stage. (Fig.13.)—Body white, oval or elongated, furnished with an oval caudal appendage. Oral and ventral acetabula nearly equal, circular, 1-247th in. Oesophageal bulb subrotund, 1-400th in. Intestine dividing immediately after its origin from the bulb into two very capacious and moderately tortuous branches. Tail often with the appearance of an interior cup-shaped cavity; sometimes apparently perforated at the extremity ; length 1-400th in.

(Fig. 2.)}—Body oval or subrotund, smooth, beneath the epidermoid covering fasciated. Oral acetabulum placed beneath the anterior apex of the body, i-160th in., with a double oral orifice: external aperture triangular; interior round or elliptical. Oesophageal bulb oblong, 1-296th in. long by 1-222d in. broad. Oesophagus short. Intestinal rami tortuous. Ventral acetabulum orbicular, 1-174th in. in diameter, with an orifice opening into an excavation in its interior ; orifice with a thickened margin, transversely elliptical, or round when most dilated. A third orifice, generative, situated a little more than one third the distance between the ventral acetabulum and the posterior extremity of the body. Vascular system consisting of a large double tortuous trunk on each side of the body commencing ina bulbous dilatation, about the 1-666th in. in diameter, near the middle line of the body posteriorly. Furnished with a posterior contractile sac communicating with the dilatations of the vascular canals, and with the exterior. Length of the sac 1-195th in., breadth, when fully dilated, 1-470th in. Whole length 1-30th in., capable of elongating to 1-20th ; breadth 1-42d in. Third stage. (Fig. 8.)—Animal more active, usually elongated. Posterior contractile sac remaining permanently contracted, and cut off from the vascular canals. ‘The ‘latter consisting of four principal vessels on each side of the body, forming a very tortuous and intricate plexus. The principal or largest of the four vessels, furnished from its commencement posteriorly to where it turns upon itself anteriorly with vibrille. Remarks.—During the earlier two stages of the existence of Distoma vagans in Heliz alternata and H. albolabris, it is found within the pericardial cavity bathed in the liquor pericardii, and never in cysts, or in other organs of the body. The Distoma in the second of the earlier stages is the most frequently observable, and indeed it is a rare exception to find a specimen of H. alternata without it. In one instance I found as many as fifty-two individuals of the second stage together with four of the first stage in the latter species of Heli, which is an enormous number, when we consider the size of the pericardial cavity, for it measures only two lines in length by one in breadth, so that the cavity was distended by these parasites, and probably they impeded to some extent the action of the heart of the animal. ‘The usual numbers found are from one to a dozen. In the first stage the Dzstoma is more active than in the second: in the latter being sluggish and only elongating or shortening upon irritation or pressure. Usually they lie loosely bathed in the liquor pericardii, but occasionally they are found hanging by means of the oral acetabulum to epithelial shreds attached to the surface of the heart. Just before entering into the third stage, they are almost always found in the last mentioned condition. ‘The third stage is not of such frequent occurrence, or more properly it is not so readily 306 LEIDY’S DESCRIPTIONS OF DISTOMA. detected ; I have usually found it in the abdominal cavity, the retractor muscles, the olfactory sinus, or the substance of the foot. This is the most active of the three stages, and during this period it contracts and elongates the body and changes its shape into a variety of forms as are represented in figure 14, c—A. The distinctive features of the three stages are well marked, which principally are : the caudal appendage to the first stage ; the posterior contractile sac communicating with the exterior and the vascular canals in the second; and the closed vascular system and presence of circulatory vibrille in the third stage. In the first stage the vascular canals are indistinct, but a principal vessel, on each side of the body, passing forwards in a tortuous manner and then back again, are readily observable. In the middle line of the body posteriorly I have observed the outlines of a short apparent canal, which also appeared to communicate with an excavation in the interior of the caudal appendage. In some instances the caudal cavity was indistinct, in others it appeared to open exteriorly by an orifice posteriorly. The intestinal rami are comparatively much more capacious than in the other stages, and were filled with a finely granular matter, with yellowish corpuscles like oil, measuring from 1-5000th in. to 1-3333d in., and minute spicular bodies from 1-3333d in. to 1-1200th in. long, by 1-10,000th to 1-5000th in. thick. Among the granular contents of the intestines in several instances I have observed from three to ten nucleated organic cells, with granular contents measuring 1-800th in. in diameter, and recalling to mind the organic cells in the interior of the body cell of Gregarina. In the change from the first to the second stage the animal enlarges, the intestinal rami become narrower and more tortuous, the vascular canals more distinct, the central posterior short canal apparently becomes the contractile posterior sac of the second stage, and the caudal appendage drops off leaving an opening at‘the posterior part of the body communicating with the contractile sac. The removal of the tail is gradual, it commences at the place of attachment to the body, by an absorption anteriorly and posteriorly, so that it hangs by two peduncles one upon each side, and resembles a cup suspended by two strings from the posterior part of the body. These peduncles are next removed, and the tail is detached, and sometimes the animal is observed with two pointed tubercles, one on each side of the posterior orifice of the body, indicating the points of connection of the lateral peduncles. Occasionally I have met with four of these prominences, arising from there having been four points of absorption, after which for a short time the tail was suspended by means of four peduncles. Sometimes the peduncle of one side only is detached, and the tail reinains hanging upon one side by the other peduncle as is represented in fig. 9. In the second stage the body is furnished with distinct transverse muscular bands, a condition which was not distinguishable during the first stage. (Fig. 2.) LEIDY’S DESCRIPTIONS OF DISTOMA. 307 The posterior contractile ventricle or sac is an oblong cavity with muscular parietes, the longitudinal strie of which are quite distinct. It communicates with the exterior by a posterior infundibular orifice, and at its anterior part by means of two short canals with the dilated or bulbous commencement of the vascular canal on each side. When fully contracted it forms a narrow longitudinal canal. Whether by expansion this sac takes within it some of the liquor pericardii in which it lives, and upon contraction sends it throughout the vascular canals, I did not determine. The vascular canal commences posteriorly a little in advance and laterally to the contractile ventricle, and proceeds forwards in a very tortuous manner as far as the side of the oral acetabulum, when it turns back and almost retraces its steps in the same tortuous manner to the posterior extremity of the body, where it terminates in fine branches. In its course backwards it gives off numerous lateral branches which divide and subdivide among the organs and tissues of the body, and anastomose with the corresponding branches of the other side. The oesophagus after leaving its bulb is short ; the intestinal rami first of all turn obliquely forwards and outwards and then pursue a tortuous course backwards. They are irregularly cylindrical and contractile. The contents consist of a fine - granular matter, without the spicule of the first stage. The aperture situated between the ventral acetabulum and posterior extremity, is often closed by contractile power as not to be distinctly visible. It opens into what appears to be the visceral cavity, the outline of which is distinguishable just without the course of the intestinal rami. In the change from the second to the third stage the animal loses its sluggish character, contracting and lengthening its body extremely, and protruding the acetabula,the ventral one of which appears pediculated from the cylindrical prolongation of that part of the body to which it is immediately attached. The posterior contractile sac becomes inactive, is cut off from its connection with the vascular canals, and is often indistinct. How the animal escapes from the pericardial sac Iam unable to say ; I have examined over sixty Helices without ever being able to discover anything like a perforation in it. In its third stage I have never seen the Distoma in the pericardial sac, but always in the tissues attached to the foot or in the substance of the latter itself. In this stage it is always more elongated than in the others. Instead of their being two, there are now four principal vascular canals on each side of the body, and these having a more or less tortuous course forwards and backwards forma very complex plexus. From them pass off numerous smaller branches, varying much in their course, and distributed by subdivision to all the body. In the longest of the principal vessels (from the dot a@ to din fig. 8,) the interior surface is furnished with actively moving vibrillz. This movement of the 73 308 LEIDY’S DESCRIPTIONS OF DISTOMA. vibrilla continues even after the vessel is torn into small fragments, but gradually becomes slower and slower until it finally ceases When in full activity it resembles a rapid succession of waves crossing each other, (fig. 11, a.) as it becomes slower the crossing appearance ceases, (d.) it then appears as a_ spiral, (b.) and lastly as one wave slowly falling upon the other, (c.) Inone instance I saw a corpuscle at the commencement of the vessel rapidly driven round in a circle (fig. 10,) through the agency of the vibrille. Besides this new source of circulatory movement, all the vessels have the power of contracting, even to such a degree as to become totally invisible. After this stage itis probable that this Dastoma finishes its development in some other animal, or possibly as an ectozoon, Intimate structure.-—The body is invested with a very delicate transparent epidermoid membrane, beneath which are observable transverse muscular bands, and as the animal shortens as well as contracts and elongates, we would almost infer the existence of longitudinal muscular bands. 'The latter, however, do not exist, and the shortening is produced by the same bands which produce the elongation. This appears at first thought almost impossible, but the arrangement of the muscular bands is peculiar, very remarkable, and renders the two opposite movements perfectly easy by the same set. Instead of being continuous bands, they are isolated muscular or sarcous cells arranged in rows and separated by narrow intervals, which from their inherent power of shortening and lengthening in any direction will give the body a resultant movement. ‘This arrangement and change will be better understood upon referring to figure 12. When the sarcous cells are extended transversely to their greatest extent, the body appears broadest. As these shorten, the body is narrowed and somewhat elongated. When they reach their greatest degree of contraction they then elongate in the direction of the length of the animal, and the elongation of the body corresponds to the extent to which the sarcous cells are capable of extending in that direction. These cells appear homogeneous, opalescent, and translucent. Within the muscular layer and forming the general parenchyma of the body is a fine, transparent, vesicular structure. These vesicles are very delicate, contain no nuclei, and measure from 1-12,500th in. to 1-3570ch in. in diameter; some I measured as large as 1-1850th in. These same bodies either fill up the interspaces between the viscera in the visceral cavity, or else they form a layer upon the interior parieties of that cavity, a point I could not determine. The acetabula are hollow globular bodies with thick muscular parietes, the latter character being distinguished by the striation and inherent contractility. The mouth is a sort of shallow canal, formed by the thickness of the parietes of the oral acetabulum. Both orifices of this oral canal are capable of contracting LEIDY’S DESCRIPTIONS OF DISTOMA. 309 together or separately, and one may be frequently more contracted than the other, as is represented in fig. 4. In expansion the inner orifice usually appears round, the outer one triangular. In the greatest degree of contraction the outer orifice looks like a transverse slit with puckered edges as in fig. 3. The orifice of the ventral acetabulum when opened is transversely elliptical, (fig. 5.) In some instances I have observed several round granular corpuscles moving in the cavity of this acetabulum during its movements of contraction and expansion. Dujardin* speaks of a Distoma found in the intestine and liver of Limaces, which bears considerable resemblance to D. vagans. The latter is, however, larger, and never occupies the position of the former. *Hist. Nat. des Hel., p. 472. 310 LEIDY’S DESCRIPTIONS OF DISTOMA. REFERENCES TO PLATE XLII.

In the present essay I have made many innovations in the former arrangements of these insects. These will be found more obvious in the first group, the Lepturide. The indistinct characters of the genera as left by Serville and Mulsant, have long rendered some other classification necessary ; since being founded on very slight and arbitary differences of form, they unite together many species which, agreeing in certain trivial circumstances, differ widely in general appearance. Such is the genus Pachyta, which on account of its heterogeneous nature I have been compelled to suppress altogether. Such again is Grammoptera, which was established on Lepture -with linear elytra. If a comparison of a large number of species be made, this character is found to be entirely fallacious, so that however clear the mathematical distinction may be between lines that are and are not parallel, it will be seen that in nature this distinction cannot obtain. The proportions and form of the elytra vary in all the genera, and it would be quite as rational to separate into distinct genera, those with incised and those with dehiscent elytra. Although these characters are thus shown to be mere specific marks, we may derive much aid from them in forming sections in those genera which contain many species ; they may thus be made to alleviate the labor of identifying species: and in 79 312 LE CONTE.—LONGICORN COLEOPTERA the following pages have been made to contribute greatly to this very desirable object. Indeed, the genera Leptura and Strangaha might perhaps have been merged together, since they only differ in the degree of prominence of the posterior thoracic angles; this character is found to be variable, so that I have great doubt of its generic value. Whilst thus exposing the faults of the heretofore arrangements of this group, it is by no means presumed that the present scheme is unobjectionable. All that is claimed for it is, that it is more applicable to American species, as well as those European species which commonly occur in collections. The large increase of genera may be objected to, no less than eight new ones having been added to the Lepture alone, but these are recognized at once by certain peculiarities of habitus, and the characters on which they are founded are, so far as I know, invariable. ‘The generic table appended to these remarks will render this sufficiently obvious. There does not appear to be much accurate parallelism between the European and American species of this family ; and most of the genera found in Europe are equally developed on this continent. An exception to this principle is found in Rhagium, of of which we have but a single species. Vesperus and Rhamnusium are peculiar to the old continent, but here Desmocerus represents the former and Centroderus the latter. Peculiar to America are Piodes, Gaurotes, and Typocerus, the five other new genera are distributed over both continents. There are two species of this group which are indigenous to Kurope and America, viz: Acmeops strigilata and Strangaha sexmaculata: they are confined to the Northern regions neither of them occurring south of Lake Superior. The genus Distenia will be found among the Cerambycide. I know not why it has been associated with the Lepture, with which its affinity is very slight: it is much more closely allied to Eburia and Cerasphorus. Before passing to the specific details of this tribe, it may be proper to say a few words on the characters which distinguish the Lepture from other sections of the Longicornia, and to ascertain the true value of the division which they form. Longicornia have been divided by Latreille, Serville, and other authors, into three groups, Prionide, Cerambycide, and Lepturide. ‘The first group distinguished by the defiexed labrum, rudimentary inner-maxillary lobe, and the antenne inserted in front of the eyes. ‘The second group has the head not narrowed into a neck and the antenne are placed between the eyes. ‘The third is separated on the single character of the head being narrowed posteriorly into a kind of neck. The second group is again divided into two: Cerambycint, with porrected head and dilated palpi, and and Lamiari, with deflected head and piliform palpi. This arrangement is very unsatisfactory, since by following it, we associate with Prioni, Asemum, Criocephalus, and other genera, which in form are true Calhidia ; OF AMERICA NORTH OF MEXICO. 313 while Distenia, although strongly resembling Cerasphorus, is put among Lepture. Again, there are many true Cerambyci, (e. g. Itenopterus,) which have the head elongate and porrected : Necydalis likewise has the head suddenly contracted behind precisely like Tozxotus, while the front is deflected and the palpi filiform; so that it becomes difficult to determine whether the genus belongs to the Lepture, Ceramby ct or Lamia. So fallacious are the received characters, that a genuine Saperda-form with abbreviated elytra, has been described both by Newman and Haldeman as a Molorchus, (Thia, Nm., Tessaropa, Wald.) and another genus (Lncylops, Nm.) allied to Necydalis, has been placed near Tozotus. A new genus from Georgia has a remarkable resemblance to Dorcadion, whilst the head is prolonged behind the eyes, and its true affinity is with the gibbous Clytz. It is thus plainly seen that these divisions so distinct in nature, have not yet any natural distinctions in our systems. Dr. Zimmerman has recently recognized the importance of a character heretofore neglected, and through his kindness I am enabled to make use of it in the present essay. He finds that in all Lamia-forms, the anterior tibiz have an oblique sulcus internally, which in many cases becomes so deep as to form an emargination, such as 1s observed in most Carabica. This character, with a single exception, is wanting in all other Longicornia. Making use of it and at the same time suppressing the primary group Lepture, as not possessing sufficiently distinct characters, we obtain three great divisions which embrace all Longicornia. 1.

The Lamie* meet the Cerambyci in several points, Dorcadion tending towards Clytus, while Saperda unites with Necydalis; some tropical forms tend towards Dorcacerus. The Prioni meet the Cerambyci in two points. Pyrodes approaches Megaderus and Tragosoma, Asemum : they then lead to the Lamellicornia in Lucanus. ‘The Leptura branch of the Cerambyci is related to the Phytophaga by Acmeops, which approaches Donacia. Piodes is a very anomalous form which seems closely allied to the Priont, but I am inclined to believe it more nearly related to Megamerus Kingz, (McLeay) among the Phytophaga, which is said to have the same coriaceous structure as the Prionus and Piodes. On the other side, this branch is closely connected with the Cerambyci by Necydalis, so that no character can be used to separate them, excepting the conical coxe. The Spondylus branch is related to the typical Cerambyci, through Asemum and Callidium: this form attains its highest development in Hypocephalus, which is another isolated form connected only with the contents of its own group. The very peculiar appearance of the Spondylide might lead many to consider it as of equal value with that which is observed in the Lami@ or Prioni, separating them by their short and robust lees, with dilated and dentated anterior tibie. Now, although these species differ in this respect from the typical Cerambyci, yet on comparing several together, great differences are found in these same organs. Hypocephalus has only a few large teeth on the tibie, Spondyls buprestoides a fine serration, while Scaphinus (Prionus muticus, Fabr., Spondylis sphericollis, Lec.) has a large expansion at the end of each tibia. The antenne of Spondylis are at the base of the mandibles as in Prionus, but on examining the Calhdia a gradual transition will be found between this position and the one assumed in the typical Cerambycz. The relations just pointed out, as far as they can be exhibited on a plane surface, are shown in the following diagram. *This group is to be considered as the highest form of the Longicorn beetles; since with perfection of organisation, it is entirely free from all complicated relations. Its affinities are only with other Longicornia, and with only one section of them ; and this isolation must always be a property of the highest division of any group, no matter what its extent may be, since the highest form is that in which some typical idea attains its maximum of development. We find in every group a highest form, in which, to use a physical symbol, the branch terminates, and in every case the comparative value of this branch may be ascertained by tracing its connection with others ; that which soonest assumes a distinct form will be the highest. 315 OF AMERICA NORTH OF MEXICO.
