214 PROCEEDINGS OF THE ACADEMY OP 



lated by granules, seven-plated, of which three are largest ; all smooth. Loreal 

 rows five ; inferior and supralabials nine, the former bordered by one row ante- 

 riorly, posteriorly by three rows of infralabials. The " mental " plate large, in 

 contact medially by their anterior angles only. Auricular opening large ; 

 goitre none, (probably the specimen is a female.) Dorsal scales very small, 

 those of the lower part of the sides perhaps smaller. The exposed faces of 

 the extremities covered with large, weakly-keeled or smooth scales. Tail 

 without crest, covered with small scales, at intervals verticillate. Anterior 

 extremities extending to behind the groin, posterior, to end of muzzle. Length 

 of head to auricular opening 7 lines; from ear to vent 14 lines. Tail elongate, 

 (mutilated.) 



Above silvery gray, with four chevron-shaped brown cross-bands ; a similar 

 band upon the nape. The muzzle, occiput, extremities and sides of the neck, 

 are varied with pale brown, the last in a longitudinal manner. A short sil- 

 very band from inferior border of orbit to ear. Beneath white, with golden 

 and green reflections ; anal region and inferior surfaces of femora yellow. 



One specimen from Monte Verde, Cuba, sent to the Mus. Smithsonian Inst, 

 by Mr. Chas. Wright, (No. 5737f.) 



This interesting species pertains, as to its form, to the same group as c y - 

 anopleurus, exhibiting the same elongation of head and hinder extremi- 

 ties ; but the squamation is that of A. al li ga t o r or b u 11 a r i s. 



Anolis (Ctenocercus) i s o 1 e p i s Cope. 



Allied to A. vermiculatus and angusticeps. Size small, form stout, 

 bead large, extremities short. Muzzle quite elongate, depressed anteriorly ; 

 nostrils vertical, longitudinal, their posterior border at a point marking one- 

 third the space between the end of the muzzle and anterior border of the orbit. 

 Auricular opening not larger than nostril. Front very plane, facial ruga? not dis- 

 tinct, more acute anteriorly, where they converge. Canthus rostralis very pro- 

 minent, straight. Superciliary ridges but little prominent, each protected by 

 four plates. The most anterior of these is the largest, and in line with a lon- 

 gitudinal row of large, smooth, elongate, hexagonal shields four or five in 

 number, the last three pair elongate and in contact. They are separated by one 

 series of small scales from the rostral plate, and are in contact with the plates 

 of the canthus rostralis, and with a median series of similar plates which ex- 

 tend to the occipital. The latter is small, and separated from the superciliaries. 

 Palpebral disc irregular, having two or three plates much larger than the 

 others. Loreal rows three ; upper labials eight ; inferior labials nine, elon- 

 gate; infralabials large, faintly many-keeled, in a single series anteriorly, 

 posteriorly in three rows. Goitre very small. The scales of the neck, body, 

 and extremities (except the inner surfaces of the latter) are of nearly equal 

 size, round or oval, nowhere keeled, but thickened medially. The extremities 

 are short, the anterior reaching two-thirds way to the groin, the posterior to 

 the shoulder. Digital expansions broad. The tails of the specimens are mu- 

 tilated, except in a young male, where it is entirely cylindrical, covered with 

 small keeled scales distantly verticillate ; its length is once and a quarter that 

 of the head and body. Number of maxillary teeth in adult male about twenty- 

 one ; of these only about twelve are tricuspidate. Teeth on the os palatinum. 

 In the female the head is shorter, and hence with more convergent lateral out- 

 lines. Total length, young ^, 30 lin. ; tail 17 lin. Length of head and body, 

 (-J 1 , 1 in. 6 lin. ; head to ear 6 lin. Ditto, in Q > 1 m - 4 Kn. ; 5 lin. 



Coloration. Greenish glauceous blue, paler below. A narrow light line ex- 

 tends from upper lip to auricular opening, and in the female there are a few 

 dots of the same color. She has also a series of indistinct dark spots on each 

 side of the median line posteriorly There is a purplish tinge about the jaws, 

 which prevails upon the whole body when the epidermis is removed. A 

 young male is ornamented with a few broad transverse bands on the back and
