This notice contains a list of the species of Iguanidre at present represented in the Museum of Comparative Zo- ology, at Cambridge, Mass., with localities and notes, and with descriptions of such as are new or little known. It includes a tolerable proportion of all the species hith- erto recognized as belonging to this region, together with quite a number that do not appear to have been described. The list was prepared some years ago, but, owing to un- certainty in regard to some of the species discovered in the early part of the century, the types being inaccessible and the descriptions insufficient, it was laid aside until it might be put into more satisfactory shape. The splendid catalogues of Doctor Boulenger, recently published, have made it possible to identify with confidence many species which previously were, in the absence of typical speci- mens, only conjectural. The Doctor's classification has been followed pretty closely in the main ; the departures made are principally due to differences of opinion con- cerning names adopted or the relative rank of certain forms. In answer to objections that may be urged against bringing varieties as prominently forward as is usual with species, it may be said that the nature of the case seems to demand it; abrupt separation and isolation on the dif- ferent islands and consequent absence of gradual shading of the varieties, one into another, appear to entitle them to more prominence. 1 (1) 2. ON WEST INDIAN REPTILES. Unless otherwise specified the collections were matle by the writer. XiPiiocERCUS VALENCiENNii Dum. Bill'., 1837. A female has transverse bands of light brown on the limbs, a band across the neck, another immediately be- hind the shoulders and another in front of the thighs on the Hanks ; the ttul is ringed with brownish ; i)etween the eye and the car on each side of the head there is a quadrangular space enclosed b}' four short narrow lines of brown ; a streak of light color extends from the hn-eal re- gion beneath the eye to the angle of the mouth ; the gular fold is purple with a creamy border; the lips are black; the upper and the lower surface of the head are whitish ; there are short, narrow^ longitudinal streaks of brown ar- ranged in transverse series on the flanks ; and along the median liueof the back there are several small, transverse blotches of brownish, with others of light color. On a young one, less than an inch in length of bod}', the markinjxs are similar thouirh nnich lighter ; a lijjht brown band crosses the supraoculars and passes down- ward through the eye across the lips ; vertical lines of brown cross both lips in front of the eyes ; the gular fold is of a i)ink tint. In this little one the goitre is comj)ar- atively large, although the short snout, not longer than the orbit, convex on the upper surface, the disproportion- ate size of the eye and the bulged, swollen appearance of the parietal region indicate that it had been but a short time out of the e^g. Kingston, Jamaica. Anolis equestuis Mervemy 1820. There are five large specimens in the collection which are referred to this species. One of the lot is said to n IGUANID^. 3 come from Bahia, and, on examination of more individu- als from the same locality, it may be found necessary to give a different specific name. It does not entirely agree with the others in shape in front of the eyes, where the ros- tral canthus curves outward more, makino: a broader snout. It differs to some extent in the squamation of the top of the head, but the scales are so confused it is diffi- cult to discover the lines of separation. The number of lamellse appears about the same as in the others. Cuba ; Bahia. ? Coll. Anolis ricordii Dum. Bibr., 1837. On a female from Samana, San Domingo, all of the su- praoculars are keeled ; the occipital scale is very small, hardly larger than the surrounding granules, but marked by the white spot in the centre ; the color is a grayish brown, the light-colored transverse bands being sprinkled with brown scales and the brown spaces with lighter ones. Collected by M. A. Frazar. Anolis cuvieri Merr., 1820. A large specimen, presented by Dr. Aug. Stahl, of Porto Rico, is of a uniform bluish color, without the brown spots on the vertebral line ; it is tinted with yellow beneath ; the gular fold is yellow ; and the frontal region and a streak from the loreal region beneath the eyes are whitish. Anolis gqndlachii Ptrs., 1876. Young specimens have a vertebral band of yellowish color. From Dr. Aug. Stahl, Porto Rico. Anolis cristatellus Dum.

Head modertite, about one and thiee-fourths times as long as broad, nearly one and a halt' times the length of the tibia, with flat crown, very slightl,y concave on the fore- head and on the occiput ; frontal ridges -low, diverging anteriorly; with three large l)lunt-keeled scales; upper head scales with low keels ; scales of the supraorbital semi- circles hu-ge, in contact on the median line, or separated by a single row of small scales, continued as the frontal series ; seven to nine enlarged, feebly-keeled supraoculars, separated from the supraorbitals by a single row of gran- ules ; occipital as large as the ear opening, sei);uatod from the supraorbitals by three or four series ; rostral canthus sharp, of four scales ; loreal rows four to six ; six or seven labials to below the middle of the eye. Gular appendage moderate, smooth scaled. Body very little compressed, with a low dorso-nuchal fold. In the female, the goitre forms a low, longitudinal fold without the fan-like lobe. All scales obtusely keeled : dorsal and lateral granular, becomin2j lari^er toward a couple of rows of enlarged scales on the vertebral fold ; ventrals larg r than the dor- sals, little smaller than the antefeniorals, imbricate, with rounded posterior margins and feeble keels. Limbs mod- erate, the adpressed hind limb roaches the eye; digital expansions medium, twenty-two under [)halanges ii and iii ot the fourth toe. Tail compressed, slender posteriorly, more than twice the length of the body and head, with a sharp crest of unequal scales. On the male the neiu-al spines support a lin-like expansion extending not more than half the length. Enlarged post-anal scales. Gray, greenish, bluish, or brownish, bronzed, with or without spots or vermiculatious of brown on nape, flanks. IGUANID^. 5 chin and limbs ; lips with or without brown spots. A young one has a large, rounded white-edged spot of brown above each shoulder ; on another these spots are obsolete. Readily distinguished from A. cristalellus^ which it closely resembles, by the greater size of the two verte- bral rows. From Professor L. Agassiz ; Silver and Lena Keys, Fla. Anolis striatulus Cope, 1861. From Professor Ackerman, Port an Prince, Hayti ; Dr. Aug. Stahl, Porto Eico ; Hassler Expedition, St. Thomas. Anolis gingivinus Cope, 1864. Dr. W. J. Branch, Anguilla Island. u Anolis bimaculata, Sparrman sp. These notes are taken from forty-six specimens secured on St. Kitts. The species is usually confounded with sev- eral others to which it is somewhat closely allied. It is distinguished by the size of its granules, the four to five loreal series, the broad smooth plates in front of the thigh, the meeting of the opposite supraorbital series on the forehead, in seven specimens of each eight, and by the coloration. The color is blue or green, grayish to broAvnish ; white beneath. Posteriorly, on the flanks and on the tail, usually there are present a number of small spots of black, irregu- larly scattered but often forming a rounded bunch in front of the thiffh on the side ot the abdomen. Above the axilla there is most often a rounded black spot. Rarely it is continued forward as a band to the angle of the mouth. From the upper labials there is a light band crossing the upper half of the ear to end on the flank above the shoulder. 6 ON WEST INDIAN REPTILES. Above and in front of the shoulder, below the dark spot, there is another l)and of light color, and there are faint indications of a third from each side of the occiput to the nape. The lips are yellowish ; generally each bears a series of dark spots, more or less numerous. Commonly the head, from the hinder edge of the orl)its forward above the labials, is dark brown. The throat and neck are in cases clouded by darker. The prominent marks are the black spots above the axilla, the white patch in front of the shoulder, the dark mark behind the ear, and the small black spci^ks. None of these specimens have scries of ocellate sjxjts on the flanks. We have specimens of this lizard from Nevis, also, where it is the "Blue lizard"; this raises the question as to the identity of Merrem's species with Edwards' lizard from Jamaica. Anolis oculatus, sp. Cq;;e, 1879. At several points on Dominica a lot of eighty-one spec- imens was !2:athcred. From them it is evident that the species should not be united with A. bunacniaius of Sparr- man, althouglifthey discover a considerable amount of va- riation. In color they range from light grey to nearly uniform dark brown. On the majority the white marks form transverse series of six to eight spots each. A spot near the middle of the flank in each series is lai'ger and more distinct than the others; in this wav a loni^itudinal row is formed on each side which persists on specimens from which the ti-ansverse series huve faded. In cases there is a short white line from the shoulder backward ; occasionally there is also a second, parallel to the first, separated from it by a dark space. Above the shoulder, and a little backward, there is usually a dark spot includ- ing one of the white (mes, often including a white one in each side of it, and behind this a short distance another. 3/ IGUANID^. 7 the latter frequently followed by a third or a series. Some are freckled by white specks on body and tail. Many have dark spots on the upper edge of the tail. The bluish white spot on the occipital scale is always present. The females are not so much spotted as the males and such marks as they have appear to be less distinct. This species is separated from A. bimaculatus by its smaller scales, by the sharp keel on the largest scales in front of the thigh, by the greater number of loreal series, by the separation of the supraorbital series on the fore- head, and by the coloration. It has six to eight loreal series and tiie supraorbitals are separated by one to three series of granules in seven of each eight individuals. There are about tw^enty-three lamellae under phalanges ii and iii of the fourth toe. This may be one of the two species A. maculatus described by Dr. Gray, but it is not to be de- termined from his description. Hah. Dominica. Anolis asper, sp. n. Head moderate, one and a half to one and two-thirds times as long as broad, longer than the tibia, crown flat- tened, cheeks swollen in the males ; snout rather broad ; forehead to occiput concave ; frontal ridges low ; upper head scales not keeled ; scales of the supraorbital semi- circles broad, three pairs in contact on the median Hue, usually separated from the occipital scale, which is about the size of the ear-opening, by one to two rows ; seven or eight indistinctly keeled supraoculars, smooth in young, most often in contact with the supraorbitals ; rostral canthus sharp, straight, canthal scales three to four ; loreal rows three to four ; six labials to below the centre of the eye ; ear opening rather small, vertically elongate.

Dorsal scales small, granular, keeled, rough to the touch, larger on the back than on the flanks ; ventrals larger than dor- sals, smooth under the abdomen ; antefemorals larger than ventrals, keeled. The scales have a swollen appearance, and on the larger specimens might be described as sul)- conical ; this is especially marked near the occiput and among the larger ones of vertebral rows. The adpressed hind liml) reaches the eye ; digital expansions large; the lamelhe under phalanges ii and iii of the fourth toe num- ber about thirty. Male with enlarged post-anal scales.

Greenish or olivaceous to reddish brown or grayish on the back and flanks, with or without cloudings of darker ; forehead often darker; ventral surface lighter to whitish. A series of more than thirty specimens was purchased from j\Ir. W. B. Richardson who secured them on the isl- and Marie Galante. Closely allied to A. ferreiis, Cope, from Guadaloupe ; distinguished by small lateral scales, three pairs of supra- orbitals in contact between the orbits, three to four loreal rows, etc. Anolis marmoratds Dum. Bibr., 1837. As has l)een remarked by Dr. Boulenger, this species is closely allied to A. bimaculatus. The principal distinc- tion lies in the coloration. The average size of our speci- mens is much less ; and apparently the snout is a trifle more pointed, with canthus and ridges sharper. Ilab. Desirade. AV. B. Richardson, 52 ex. Anolis nubilus, sp. n.

Tail ringed with broad bands and head clouded with brownish. A very young specimen has a dark edged vertebral band of light color which is not crossed by the transverse marks. This variety of A. cepedii is known from twenty-five specimens taken by the writer on Petit Martinique, one of the Grenadines. Anolis cinereus, var. n. This variety of A. cepedii differs from A. trinitatis in being more olive or bluish ; the legs show more of the lilac 'color, and, on our specimens, the transverse bands are obsolete. The color is intermediate between that of light-grayish varieties, from Trinidad and Petit Marti- nique, and the brownish, from Barbadoes. Hob. Grenada. Twenty-four specimens. Anolis trinitatis ReinJi. & Liltk., 1862. This form has a lighter, more grayish color than the other varieties of A. cepedii, and in consequence the transverse bands and the small black or brown spots are more distinct. Hab. Trinidad.

Dorsal scales small, very irregular in sizes, six or eight rows of the vertebrals enlarged and keeled, those on the flank smaller. Ventrals larger, sub- hexagonal, juxtaposed, smooth. Limbs medium ; ad- pressed, the hind leg reaches a little in front of the ear; digital expansions moderate ; lamellae under phalanges ii and iii of the fourth toe about twenty-seven. Tail feebly compressed, nearly twice as long as head and body, ser- rated on the upper edge with low subequal strongly keeled scales. No enlarged post-anal scales. Grayish to brownish olive, with or without faint trans- verse bands of brown on the anterior portion of the body and on the tail ; more blue on the flanks and beneath ; head darker. On back and flanks there are indistinct traces of [ 22 ON WEST INDIAN REPTILES. vermiculations in light iiidescent tints. On young ones there are five transverse bands on the body ; these indi- viduals are more gray, or brown, than the hirge. Hab. St. Lucia. Thirty-three specimens. Anolis vincentii, sp. n. Head of medium size, about one and three-fourths times as long as wide, longer than the til)ia, deeply concave on the forehead and occiput, slightly depressed on the snout; frontal ridges distinct, not extending forward, prominent and rough between the orbits in adults ; up- per head scales not keeled ; scales of the supraorbital semicircles large, more or less in contact between the orbits ; nine to fourteen enlarged keeled supraoculars, separated from the supraorbital series by a series of granules ; occipital twice as large as the ear-opening, anterior border rounded, in contact with the supraoc- nlars ; canthus rostralis not very distinct, of two large and two or three short scales ; loreal rows five to six ; seven to eight labials to below the centre of the eye ; ear opening hardly half as hirge as the occipital, vertically oval. Gular appendage large, reaching behind the thorax, scales smooth. Body little compressed ; a slight dorso- nuchal fold. Dorsal scales small, keeled, increasing in size toward the two mesial rows which are largest. Ven- tral scales smooth, subhexagonal, hardly imbricate, smaller than a few of the antefemorals ; the latter moderate, keeled, near the knee tricarinute. Limbs medium, the adpressed leg reaches the ear ; digital ex[)ansions not large ; lamelhe under phalanges ii and iii of the fourth toe about twenty-six. Tail compressed, serrated on the upper edge by large, sub-equal, pointed scales, more than twice (two and one-fourth times) as long as head and body. Postanals not enhir<>:ed. IGUANID^. 2 Green to brownish olive; flanks, sacral region, limbs and tail more or less purple or lilac in life ; ventral sur- faces whitish ; gular fold darker, anteriorly, as also in cases, the lower surface of the neck.

K. Shaw ; the Florida Keys by Count L. F. de Pourtales ; and from Nassau, Bahamas, by J. C. Comstock. Anolis porcatus Gray, 1840. This Anolis is usually confounded with the A. princip- alis Linne, from the southern part of the United States. The species are in reality quite distinct, though bearing considerable resemblance to each other. Compared with representatives of A. principalis from the Carolinas, A. porcatus has a longer snout, stronger and sharper cephalic ridges, a longer tail, longer legs, more digital lamellas and 24 ox WEST INDIAN REPTILES. larger scales on the loreal region and on the flanks. The snout is twice the length of the space between the orbit and the car; the frontal ridges are vcr}' prominent, sharp and comparatively straight, forward from the interorbital space ; adpressed, the leg reaches to the middle of the space between the orbit and the ear ; the lamelhv^ under phalanges ii and iii of the fourth toe number about twen- ty-eiglit ; the tail is more than twice as loug as both head and body ; and the loreal rows are commonly three, some- times four. On A. principalis the snout is but about one and two- thirds times the length of the space between the orbit and the ear ; the frontal ridges are less sharp and prominent, and spread farther apart or are more crooked in the pre- frontal region ; the leg reaches the anterior border of the ear ; there are about twenty-five lamellae under phalanges ii and iii of the fourth toe ; the tail is about one and three-fourths times as long as head and body ; and the lo- real rows are live, rarely six or four.
