62 ON WEST INDIAN REPTILES. 



little compressed, male with a dorso-nuchal fold. 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 sub- 

 conical ; this is especially marked near the occiput and 

 among the larger ones of vertebral rows. The adpressed 

 hind limb reaches the eye ; digital expansions large ; the 

 lamellae under phalanges ii and iii of the fourth toe num- 

 ber about thirty. Male with enlarged post-anal scales. 

 Tail compressed, not twice as long as head and body, with 

 a serrated upper edge, which in the male is borne on a 

 broad fin-like expansion. 



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 Mr. W. B. Richardson who secured them on the isl- 

 and Marie Galante. 



Closely allied to A. ferreus, 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 marmoratus Dum. Bibr., 1837. 



As has been 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.

Anolis nubilus, sp. n. 



Head large, somewhat similar in shape to that of A.
