L—An atlempt to classify the Longicorn Coleoptera of the part of America North of Mexico. By Joun L. LeConre, M. D. (Concluded from page 340.) Subdivision Il. CERAMBYCIDE. The same objections that have been already made to Serville’s arrangement of the Lepturide, may be urged with still greater force against his classification of this subdivision, since the number of generic forms being very much larger, the difficulties experienced in an artificial classification depending of superficial characters become much increased. His primary subdivisions being formed on differences in the outline of the thorax, the student is frequently left in doubt where a genus should be placed ; and, indeed, if his system were rigidly followed, many species would be separated from their congeners, and placed in a very different position from that which nature indicated. Examples may be observed in the genera Llaphidion and Arhopalus, as defined below. The affinities of this subdivision have been sufficiently pointed out in the introduction ; it is the central group of the Longzcornia connected with all the others. Its affinities being of this radiating nature, we would naturally expect to find it subdivided into a series of groups, each verging more or less in the direction of one of these radiating lines. In a group thus constituted, the dichotomous principle invariably adopted by the French naturalists fails completely, and we are VOL. 11.— 2 6 LE CONTE.—LONGICORN COLEOPTERA obliged to seek for an assemblage of characters to define our groups, instead of basing them on isolated peculiarities. This method I have endeavoured to pursue, and as far as the limited materials existing in American collections could give me aid, the genera of this subdivision may be divided into the following groups.

I now proceed to define these groups, giving at the same time a list of the genera which each contains. In many cases, owing to the indefinite nature of Serville’s tables, there is some doubt where a genus should be placed, in such cases I have added a note of interrogation, to signify that I had no opportunity of examining the genus.

In this group the body is elongate and somewhat cuneiform as in the Purpuricenus group, from which they are distinguished only by the mesosternum being deflexed anteriorly. The thorax is either armed or not, but is not wider than the elytra, which are rounded at the apex. The antenne are setaceous and very long in the males, and their last joint is divided or very nearly so; the palpi are but little dilated, the maxillary being longer than the labial; the femora are not clavate, and the joints of the abdomen gradually diminish in length. The posterior tarsi are not elongated. SMILECERAS. Antenne pubescentes. %. Sub 12-articulate, articulis 4—7 gradatim longioribus, 5—11 extus acute marginatis. Thorax lateribus dilatatus Eitubered ing: tuberculo posteriore subacuto. Scutellum subelongatum acutum, Mandibule obtuse. The joints of the antenne from the fifth to the end, have their anterior margin compressed like a knife edge. The facies is very like Hammaticherus, to which I should have referred it, but for the structure of the mesosternum. The maxillary palpi too are longer than the labial, and the joints of the antenne from the sixth are not suddenly longer and thinner. OF AMERICA NORTH OF MEXICO. 9 1. S. sotirartum.—Atrum, supra glabrum, subtus parce cinereo-pubescens, thorace latitudine fere duplo breviore parce punctato, ante basin callo levi, alteroque utrinque versus latera modice elevatis, basi sinuato, elytris subtilisime strigosis, parce subtiliter punctatis, pedibus cyanescentibus. Long. 1°43. Cerambyz solitarius, Say. J. A. N.S., 3, 410, Callichroma solitarium, Hd. |. c. 32. A single specimen was found in New Mexico by Dr. Wislizenus and presented to me. Say’s specimen was found on the Arkansas near the mountains. Group 4. This group forms the passage from those with gibbous sterna to the succeeding groups. The body is elongate, sometimes subdepressed, resembling Ilaphidion, sometimes Purpuricenus, but from both of these sections the present is distinguished by the bifid mandibles. The antenne (as far as known to me) have twelve joints in both sexes, in Deltaspis the last joint is indistinct, the palpi are short and but little dilated, the maxillary but little longer than the labial; the femora are not clavate : the posterior tarsi scarcely elongated, the joints of the abdomen are nearly equal. TYLOSIS. Mandibulz non elongate. ‘Thorax rotunde depressiusculus, dorso callosus. Mesosternum subplanum antice non subito declive. Elytra apice rotundato, truncata non armata. Corpus nitidiusculum, parce brevissime pubescens. Differs from a Mexican genus which I consider a Ceragenia, in having the thorax unarmed and the elytra not armed with a spine towards the tip; the mesosternum is not at all gibbous. The 12th joint of the antennz is very distinct, and in the % these organs are much longer than the body. 1. T. macutatus.—Niger, thorace elytrisque coccineis, illo latitudine fere duplo breviore, punctato, callis, 5 levibus nigris modice elevatis, elytris confertim punctatis, macula humerali alterisque utrinque tribus nigris. Long. -75. New Mexico, Dr. Wislizenus; the spots on the elytra are placed near the suture, the second isa little before the middle, and is somewhat transverse, the third elliptical near the tip; the humeral spot is sometimes obsolete.* * A small Mexican species of this genus, which seems nondescript, may be thus characterized : T. octtatus —Niger, thorace elytrisque coccineis, illo latitudine yix breviore, ante basin anguste constricto, confertim punctato, callo utrinque ante medium leeyi nigro: elytris confertim punctatis immaculatis, scutello nigro. Long. -45. ' Puento Nacional. Mr. Pease. 10 LE CONTE.—LONGICORN COLEOPTERA Group 5. The body in this group is elongate, sometimes slightly cuneiform, sometimes subdepressed. The thorax is most commonly convex, either armed or unarmed, and but little dilated on the sides. The palpi are short and more or less dilated, the maxillary sometimes being a little longer than the labial. ‘The mandibles are entire. The legs are thin, the posterior pair frequently elongated. ‘The mesosternum is not at all gibbous. This group differs from the two following by its simple femora. It leads directly to the Clytz. TRAGIDION, Serv. Mandibulee obtuse breves. Antenne filiformes 11-articulate (% sub 12-articulate) articulis 5—11 extus margine acuto. Thorax convexus, parum rotundatus, spicula parva armatis. Palpi breves, labiales brevissimi. Elytra apice haud armata : corpus valde pubescens. I know not what induced Serville to associate this genus with Clytus ; in every respect it strongly resembles Purpuricenus, and can be distinguished only by its shorter palpi and thick pubescence, which covers the body both above and below ; this pubescence is more dense in the female. . 1.

Grove 8 Is distinguished from all the other sections of the present tribe by its perpendicular front : the antenne being inserted so high on the head as to produce a large quadrate face, almost as in the Lamia. The femora are always clavate, and the anterior acetabula round. ‘The thorax is convex and sometimes even compressed. This group approaches very closely the Saperdoid and Dorcadoid Lamia, and can, indeed, only be separated by a reference to the diagnostic characters derived from the palpi and anterior tibie. ‘The femora are dilated in all Clytz, whilst they are filiform among Lamia. For this reason I have separated Clytus supernotatus, Say, and pygmaeus, Hald., to form new genera among the Lame: both of these species have the anterior tibie obliquely sulcate inwards. The large Clytz with yellow bands have already been united with Arhopalus, since their femora are scarcely clavate, their thorax subdepressed, and their front only slightly deflexed. CLYTUS, Fadr. Antenne breviuscule, crassiuscula, pubescentes minime pilose. Oculi subtriangulares, supra emarginati. Thorax scaber, convexus, non compressus, haud armatus. Elytra haud gibbosa ; corpus pubescens.

Sometimes the whole of the under surface, except the abdomen, becomes testaceous, the transverse cinereous line is not confluent with the oblique ones, and the apical pubescence extends nearly up to it. Found from Massachusetts to Georgia. 2. C. nicer.—Niger, thorace modice compresso ; elytris basi paulo gibbosis, postice cinereo-pubescentibus, apice integra, antennis non spinosis. Long, 32, Lec.

Long. -21—-3, Clytus nicipes, Fab. New York and Georgia, abundant. Varies with the anterior half of the elytra, the pectora, feet and antenne rufo-testaceous. Group 9. This group is founded on a very remarkable insect having the appearance of Dorcadion or Parmena, caught in the mountains of Georgia. It continues still farther the last group in the direction of the Dorcadioid Lamia, but presents such a curious assemblage of characters, that it is very difficult to know where it should be placed, although its true affinities are obvious at first sight. From the preceding group it is distinguished by its large exserted head, short and but slightly inclined front, and entire acetabula, in which it agrees with the fourteenth group alone of all that have been seen by me. The antenne are very widely separated and inserted under a slight margin. They are partly embraced by the eyes, which are very narrow, almost divided, and situated obliquely with the superior portion larger than the inferior. The maxillary palpi are as long as the head, the second and third joints equal and triangular, the last joint very much dilated and securiform; the anterior tibie have on the posterior face a distinct oblique groove, a character which is found nowhere else in this tribe, and which at once indicates a strong affinity with the Lame. MICHTHISOMA. Caput exsertum. Thorax ovalis, convexus, postice angustior, lateribus spina acuta obliqua postice armatis. Femora crassissima, tibiis anticis modice curvatis, articulo 1"° posticorum elongato. Elytra connata, convexa apice singulatim rotundata. The elytra are depressed and almost margined at the base, which gives them an almost gibbous appearance. The anterior femora have a slight angle beneath near the base. The antenne are filiform and as long as the body, with a few sete. 1.

OF AMERICA NORTH OF MEXICO. 31 Found near the top of Yona mountain. The elytra are twice as long as the head and thorax, a little dilated to the middle, from which place they are gradually and somewhat obliquely narrowed. Group 10. This group begins the approach towards the Spondylide, by having the anterior acetabula externally prolonged into an angle. By this character it differs from all the preceding groups, except some members of the sixth, but these are immediately distinguished by their cylindrical palpi; they are all depressed elongated insects with rarely any armature to the thorax or elytra, the latter in a great majority of the genera are rounded on the sides. The femora, as far as I have been able to examine, are always very much clavate. HYLOTRUPHES, Serv. Oculit valde emarginati. Palpi labiales marginales zequantes. Labrum integrum.

I should have considered this as the true Cail. collare, Kirby, were it not for the absence of the lateral thoracic protuberance.

The punctuation of the thorax is sometimes very sparse : it varies in form being rarely transverse. The male has longer antenne than the female, and their base is a little thickened. Group 11. This group completes the approach to the Spondyhde : it contains species with the anterior acetabula still more prolonged externally than the preceding group, and the eyes are simply transverse, not embracing the antenne, which are situated at the base of the mandibles and in front of the eyes; the inner lobe of the maxille is sometimes obsolete. © ASEMUM, Esch.

It seems closely related to the fifth group, especially Kdurza and Cerasphorus, but the palpi are more elongated, and the antenne are situated at the base of the mandibles, entirely in front of the eyes, which are simply transverse. The anterior acetabula are round and the coxe large, the mandibles are truncate at the apex, with the edge acute. DISTENIA. Palpi maxillares labialibus duplo longiores.

OF AMERICA NORTH OF MEXICO. 37 This genus has been associated with the Lepture, on account of its head, which is a little narrowed behind the eyes, and more porrected than is usual in the present tribe ; we have already seen that these are not reliable characters, and I have removed it from the Lepturide on account of its globular anterior coxe. 1.

In this group the highest development of the tribe is reached: the anterior acetabula are round and entire; the front immediately below the antenne is perpendicular, but from the oblique position of the mandibles this is not very conspicuous. But what especially distinguishes this group is the very slight development of the maxillary palpi, which are cylindrical, and do not extend beyond the lobe of the maxilla. The labial palpi are longer and slightly dilated. This group seems related to the typical Lame. CALLICHROMA. Mandibule elongate, recte, pyramidate.

Cretaceous limestone. A smaller species than the preceding, and differs in being emarginate posteriorly ; in the anus not being transverse ; in the more rounded disk, &c. This limestone in New Jersey is linked with the green sand by the presence of Ostrea vesicularis, Gryphea vomer, &c. The same rock at Wilmington, N. C., shows still more intimate connection with the lower green strata, by the presence of Ammonites placenta, De Kay ; Trigonia thoracica, Morton; and Cirrus crotaloides, which were discovered by Mr. Tuomey. Lyell and Tuomey regard the limestone at Wilmington as a member of the Eocene formation, but the occurrence in it of the three fossils above mentioned, together with the corallines of the Timber Creek beds, are sufficient evidence of its Cretaceous character. ; 40 CONRAD’S DESCRIPTIONS OF NEW EOCENE FOSSILS.

[ 3] ART. Il] —Descriptions of some American Annehda abranchia. By Josern Levy, M. D. The worms of America, terrestrial and aquatic, have as yet received but little attention from our naturalists. The following descriptions have been taken from notes which have been in possession of the author for many months, and when leisure permits, some others will be presented. Nats, Miéller.*—Opsonais, Gervais.t Body filiform, furnished with two rows of podal spines, and lateral sete ; no terminal appendages. Eyes two, placed upon the oral segment.—Lezdy. 1. Nats craciuis. Pl. 2, fig. 1.—Body whitish, linear, divided into fifty articulations, every one of which is provided inferiorly, on each side, with a set of four retractile podal spines slightly hooked at their free extremity. Articulations posterior to the fifth, excepting the two last, furnished on each side with a single long delicate seta, which are pretty uniform in length except the posterior five which gradually decrease to the last. Fifth articulation furnished with three sete on each side nearly twice the length of the others. Second to the fifth articulations inclusive short. Upper lip forming a triangle with the angles truncated, bordered with short distant, stiff, cilia-like hairs. Mouth round. Eyes consisting of a black spot on each side of the oral segment. ‘Terminal or anal segment, simple, cylindric, truncate. Intestinal canal simple, (no gizzard,) tortuous, capacious, most dilated at the seventh articulation. Ciliary movement observable in the last two segments, apparent'y within the terrnination of the intestine. Generative apparatus? Length five lines, greatest breadth one-third the length from the head .011 in. Length of sete of fifth articulation .018 in. to .0255 in.; length of the others average .012 in. Animal very active, found among alge in fresh water rivulets. 2. Nats rivuLosa. Fig. 2.—Body yellowish white, attenuated at the extre- mities, most usually in the state of division. Anterior division with twenty articulations, each furnished laterally with a fasciculus of five or six retractile podal spines, which are elongated sigmoid and terminate with a double hook, length averaging 1-250th in. Articulations posterior to the fourth furnished on each side with two moderately long sete, about 1-75th in. in length; one of them frequently * Die Wirmer der siissen und salzigen Wassers, 1771.

Upper lip triangular, studded with short stiff hairs. Mouth round. Eyes consisting of a pigment spot on each side of the oral segment. Anal segment rounded, furnished with short, stiff hairs. (Esophageal division of the intestine passing to the sixth articulation, where it terminates in the distinct, dilated, fusiform, commencement of the ventricular intestine. Cavity of the body, between the viscera, filled with free, floating, granular corpuscles. In a specimen elongated to seven lines there are usually four divisions, of which there are about 3 lines to the anterior division, 2 of a line to the second, 1} to the third, and 2 lines to the last. Breadth about 1-80th in. Habitation and Remarks.—This worm is found feeding among conferve on the soft muddy borders of clear rivulets, in the neighborhood of Philadelphia. I never found an individual which was not more or less in a state of division, in fact before the last segment is ready to separate from the pareut, there are a number of narrow segments, with rudimentary podal spines and sete, already formed at its posterior extremity, which are to become a new and distinct individual. In the average of several specimens of four lines of length when shortened, seven lines when lengthened, of four divisions, there were sixteen setigerous articulations to the anterior division, the sete being 1-75th in. long; eight to the second, with the sete comparatively very short, being yet quite rudimentary, and measuring from the 1-500th to the 1-200th in. long: thirteen to the third with the sete the 1-100th in. long; and eighteen to the last, excepting those which are rudimentary of a new division of the animal posteriorly, with sete as long as those of the first, and frequently even longer.

Fig. 3.—Body whitish, linear, composed of sixteen elongated articulations, all, with the exception of the first, furnished upon each side inferiorly with a set of eight, retractile, uncinated, podal spines, every one also supplied upon each side with three very long sete : those of the second articulation twice the length of the others: those of the last two articulations often two or only one on each side, and comparatively short Upper lip elongated into a long bent, proboscidiform process, which is soft, and bordered and studded with short, distant, stiff hairs. Eyes none. Mouth triangular. Alimentary canal consisting of a narrow * Further in the Dict. Univ. Hist. Nat. t. 8, p. 568. « Pristina, Ehren.

Anal articulation cylindric, obtusely rounded, and studded with short, stiff hairs. Generative apparatus occupying the third to the sixth articulation. Length 1 line; greatest breadth 1-150th in. Length of oral articulation with labial prolongation 1-83d in. Sete of second articulation 1-33d in. long; the others averaging 1-75th in. long. Hatitation and Remarks.—¥ ound with the preceding. ‘This animal is very active in its movements; it is abundant in its peculiar localities, and is usually found in the state of multiplication by division. When the posterior division is almost perfected, it is nearly as long and has as many articulations as the anterior, and from the oral articulation the labial prolongation appears as a rounded antero-lateral projection, (fig. 3, a.) In a wineglass of water containing some fine dirt and alge, in which were preserved for several months a considerable number of Pristina longiseta, I frequently noticed, in the dirt, minute eggs, which I supposed to belong to this animal. ‘They were white, oval, always isolated, measured 1-133d in. long by 1-130th broad, and were surrounded by a tough mucoid substance. SrRePHURIs,* 2. g.—Podal spines alternating with sete, in two rows. Upper lip moderately projecting. Girdle well marked. Number of articulations not over seventy. No muscular stomach. Blood bright red. 4. Srreppuris acitis. Figs. 4 to 7.—Body soft, filiform, acute anteriorly, increasing in thickness to the girdle, which is placed posterior to the ninth articulation, gradually decreasing in breadth posteriorly. ‘Tegument faintly reddish, transparent, through which is seen the large red dorsal and ventral vessel, with the white or brown, tortuous intestine. Articulations pretty uniformly seventy in number, supplied on each side inferiorly with a fasciculus of retractile podal spines, alternating with sete three times the length of the former. Fasciculi anterior to the girdle consisting of four podal spines and three sete ; posterior, of two or three podal spines and one or two sete. Podal spines elongated sigmoid, bifid at the free extremity, 1-229th to 1-200th in. long. Sete simple, stiff, 1-114th to 1-55th in. long. Upper lip triangular, furnished with very short straight hairs. Mouth triangular. (i sophageal division of the intestine passing as far as the sixth articulation. Oral segment 1-57th in. long.

Length 1 to 1} inches, greatest breadth at girdle 3 of a line, posteriorly 1 of a line. Habitation and Remarks——Found in the soft muddy bottom of shallow ditches in the vicinity of Philadelphia. It is a very beautiful and graceful form. When not elongated to the greatest extent, the median vessels with the white intestine (when empty) form three spirals, which through the transparent skin have a very pleasing effect. The anterior tip is whitish, the tail end yellowish. It moves with great ease through the mud, and very frequently is found buried in the latter for the anterior two-thirds of its length, with the tail end protruding vertically above the surface, which it keeps in constant vibrating motion like the Saenuris variegata, Hoffm.* When disturbed it disappears or withdraws the tail with astonishing rapidity. In the spring of the year it deposits in the mud whitish, compressed oval sacs, from half a line to a line in length, with a short tubular prolongation at each end, containing from twelve to eighteen oval eggs about 1-70th in. long. On April 2d, 1849, while walking in the outskirts of the city, I noticed ina shallow ditch numerous reddish patches of from one to six inches square, which supposing to be a species of alga, I stooped to procure some, when to my surprise I found them to consist of millions of the tails of Strephuris agils, all in rapid movement. The least disturbance would ccause a patch of six inches square so suddenly to disappear, that it resembled the movement of a single body. My friend Dr. Bridges informs me, a few years since he met with a similar instance of such an astonishing multitude of these worms. The curious movement of the tail I suppose to be secondary to respiration. Upon it I have frequently noticed numerous bunches of a sessile species of vorticella. AxroLtosoma, Ehrenberg.t—Corpus filiforme, molle, distincte articulatum ; singuli articuli setarum fasciculis utrinque barbati; ocelli nulli; os anticum inferum, labio dilatato, proteiforme superatum; anus terminalis; corpus globulis, lete rubris, internis ubique variegatum. 5, AEOLOSOMA VENUSTUM. Figs 8 to 12.—Body compressed, colorless, variegated with red spots, broad, proteiform, of eight articulations, the posterior seven of which are furnished with a pair of infero-lateral fasciculi of sete, each consisting of four, unequal and simple, the longest longer than the breadth of the body, the shortest not equal to the breadth. No sete to the oral segment. Upper lip very large, sub-oval. Anal segment broad, obtusely rounded. Intestine simple, capacious. Generative apparatus ? * Gruby, Archiv fiir Naturgeschichte, 1844. B. 1,8. 211. tSymbole Physice. LEIDY’S DESCRIPTIONS OF AMERICAN WORMS. 47 When moderately elongated 1-40th in. Found among conferve upon which it feeds, in fresh water ditches in the suburbs of Philadelphia. Remarks.—This American species of Acolosoma approaches the A. guaternarium of Ehrenberg; it is much smaller and has longer sete. The red spots everywhere dotting the inner surface of the covering, gives it a beautiful appearance. It is not so active in its movements as the preceding worms, and appears to be more aquatic in its habits. The mouth is surrounded in the greater part of its circumference by a strong muscular lower lip in the form of the letter U, with the arms presenting forward and in some degree approached to each other. When closed the sides of the lower lip approximate each other in sucha manner that the interstice of the mouth appears as an inverted 'T’, (fig. 10.) ‘The mouth opens into a wide but short pharynx, which latter, as well as the inferior surface of the upper lip, is furnished with vibrille. These appear not to have been noticed by Ehrenberg in his observations, for he makes no mention of their existence in the account of the animal. The under surface of the lower lip, as well as the lining of the pharynx, is composed of hexagonal cells, (fig. 11) into which the brick red globular bodies enter as nuclei. The vibrille fringe the edges of these ceils, and in their movement produce a current in the water towards the mouth, and are therefore an important agent in obtaining the food of the animal. The intestine is simple, moderately tortuous, irregular, and capacious, especially at the middle. ‘The latter was generally found filled with green conferve. The brick red globules variegating the posterior part of the body, appear to be coloured nuclei (fig. 12) in the muscular bands of the tegument. The median vessels which convey colorless blood are very distinct. Encuytrarus, Henle.*—Stacheln in 4 Reihen zu3 und 4, pfriemformig. Oberlippe nicht riisselformig, wenig vortretend.

Miller.s—Body yellowish white, fifty-six to sixty-five articulations, generative apparatus complete, perforations in the eleventh articulation, girdle inconspicuous or absent. Podal sete three to five in each fasciculus. Intestine capacious, no gizzard. Length five to eight lines, breadth } a line. Found under damp decaying logs, etc., in the woods near Philadelphia. Remarks.—I have not access to Henle’s description of E. vermicularis, but from what * Miill. Archiv, 1837, 8.74.

I can gather from the account of this worm in Wiegmann’s report on the Annulata in the Archiv fiir Naturgeschichte, year 1838, volume 2, page 344, and the description of Hoffmeister in the same work, year 1843, volume 1, p. 193, the above characterized worm is probably the same. 7. Eincuytraevs socratis. Figs. 13 to 15.—Body opalescent white, translucent, permitting the generative organs and the course of the intestine to be seen through the tezument, anteriorly moderately attenuated and terminating by a triangular upper lip, posteriorly cylindrical. Anal segment cylindrical, truncated. Articulations not over fifty-two, twelve anterior to the girdle, which latter is well marked. Podal spines five to seven in each fasciculus, simple. Mouth triangular, cesophagus passing to the eighth articulation, intestine simple, or frequently presenting the appearance of an oblate spheroidal gizzard in the eighth articulation. Generative apparatus perfect. Length 5 to 10 lines, breadth at girdle 1-56th in. More common than the other species, usually found in considerable numbers under the bark of damp decaying stumps of trees, or under the bark of decaying portions of living trees quite near the ground, in all the forests of eastern Pennsylvania. Remarks.—This species of Enchytraeus although quite as long as the first, has a smaller number of articulations. The podal spines in each fasciculus in this species are more than are called for in the genus of Henle, although they have the same form: simple, divergent, and with a short transverse manubrium at the origin for muscular attachment. They are usually in fasciculi of six, the central ones shorter than the outer ; anterior to the girdle, many of the fasciculi have seven spines, and at the posterior part of the body they have but five. The spines average the 1-333d of an inch long. The cesophagus is narrow and delicate to the eighth articulation, where it joins either the dilated commencement of the ventricular intestine, or an oblate spheroidal contraction of the same very much like a gizzard in appearance. At first I thought the animal possessed a true muscular gizzard, but in more than half the number of individuals examined, there was nothing existing but a dilatation of the ventricular intestine with a thickening of -the parietes, extending from within the eighth articulation to the commencement of the girdle; at other times there was an appearance of a distinct gizzard, and a dilated thickened appearance after it to the girdle, as represented in Plate 2, and in the fewest number of instances the oblate spheroidal contraction alone existed; but in all cases that portion of the intestine extending from within the eighth articulation to the girdle is strongly muscular, and may subserve the purpose of a gizzard. Within the girdle the intestine is narrow, posterior to it, it is moderately tortuous, irregular, and capacious. LEIDY’S DESCRIPTIONS OF AMERICAN WORMS. 49 In both species of Enchytracus the intervals of the body between the viscera and integument are occupied by free, floating, granular, lenticular corpuscles, (fig. 15,) each possessing a minute nucleus. The same kind of corpuscles exist in many other worms, entozoa,* etc., and may probably serve the same purpose as the blood corpuscle, although they are not their homologues. Both species of Enchytraeus are infested with a species of Leucophrys, (figs. 17a, 6,) occasionally in large numbers. From the ruptured integument of LE. soczahs, I saw, in several instances, several hundred issue. It is hemi-elliptical in outline, measures 1-300th in. long by 1-1000th in. broad, and is probably the same species as that found in Lumbricus terrestris. It is frequently observed in all stages of division, the resulting individuals measuring one-half the length of the full grown. Lumpricutus, Gruby.t—Corpus quasi teres, hyalinum, acicularum geminarum seriebus 4 armatum, Intestinum rectum, per totum fere longitudinem sacculis digitatis, vas dorsale ramis amplis, contractilibus lis respondentibus, dilatatum. Cingulum nullum. 8. LumsBricuLus timosus. Fig. 16.—Body nearly cylindrical, acute anteriorly, pretty uniform posteriorly ; color yellowish, translucent, with the dorsal and ventral vessel presenting a rich scarlet hue ; the anterior five or six articulations bordered by bluish black, central part of the body iridescent blueish. From one hundred and seventy to two hundred and twenty four articulations. Girdle none. Ninth articulation with two perforations, Generative apparatus extending as far back as the twentieth articulation. Podal spines in four rows, two in each fasciculus, of along sigmoid form, becoming abruptly narrowed at the distal extremity and terminating in a double unguis, 1-145 in. long. Upper lip triangular, 1-40th in. long from the mouth, which latter is round. Gizzard none. Length from two to four inches, breadth two-fifths of a line. Hatitation and Remarks.—This beautiful and very active worm is found under stones, dead leaves, and fragments of wood on the muddy borders of creeks and rivulets around Philadelphia. It undoubtedly belongs to the genus characterized by Gruby, but is much longer than the Lwmbriculus variegatus, Gruby. It exhibits the same regular maculations in each articulation, mentioned by Gruby{, dependant upon lateral coeca] diverticula of the blood vessels. I counted as many as fifteen of these alternately dilating and contracting vascular cceca, on each side of an articulation. The podal spines (fig. 16, a.) are of the same form as those depicted by Gruby in the Archiv fiir Naturgeschichte, Tab. vu. fig. 2,c. A little distance from the origin of each pair of podal spines, there is always to be found a pair of * Miiller, Zoolog. Dan. V. ii. p. 39.

This worm is infested with extraordinary numbers of a large species of Leucophrys. In several instances I saw several thousands issue from wounds made through the muscular investment of the body. The species differs in form from any of those which I know of, and may be characterized as follows : Leucopurys cLavata, Leidy. Figs. 18, 19.—Body colorless, clavate, very obliquely and concavely truncated anteriorly ; posteriorly attenuated, rounded or acute ; granulo-striated ; with usually six to eight large vacuola. Length from 1-200th in. to the 1-100th in.; breadth 1-857th to 1-545th in. When in a state of division, the posterior part does not present the characteristic truncation until separated from the parent or anterior division. REFERENCES TO THE FIGURES OF PLATE II.

Superior tail coverts brown with white spots. ‘Tail brownish black, with about three pairs of rounded white spots on every feather. Shafts of tail feathers black above, white below. Hab. South America? Obs.—This little Owl resembles no other species known to me or of which I have found a description. ‘The specimen above described is the only one I have seen, and was obtained from Mr. John G. Bell, of New York, deservedly well known as a naturalist and taxidermist, who is of opinion that he received it from South America. I have named this curious and handsome species in honor of Edward Harris, Esq., the distinguished chairman of the Ornithological Committee of this Academy. [ 55. J ART. V.—Description of a new species of MercuLus, Ray. from the coast of Califorma. By Wriiiam GamMBEL, M. D. Mercuuus Cassini, nobis.* Plate VI.—Bill larger and stouter than that of 1. alle, and with a yellowish white spot or band across the base of the lower mandible ; head, back, wings and tail glossy black. Throat, neck and sides grayish black or plumbeous, lower part of the back and rump tinged with the same; breast, belly, vent and spots above and below the eye white. Wings without white. of feet and legs sky blue, behind black. Total length from tip of bill to end of tail 7} inches, tarsus 1 inch, bill nearly 2 of an inch. This new species is frequent along the coast of California, and may readily be distinguished from the M. alle, which it resembles, by the absence of any white in the wing, the size of the bill, and as it turns in the dried specimen the orange spot at the base of the lower mandible, and by the sides being colored like the throat. I have named this species in honor of my friend Mr. John Cassin of Philadelphia. Front part * Originally published by the late Dr. Gambel in the Proceedings Acad, Nat. Sci. Phila.
