of quite small scales, edge thickened and set with larger scales; 



postanal plates very well developed; a skinfold on the neck and back.

snout, 9 mm.; orbit to orbit, 7.5 nmi.; snout to posterior ear, 20 mm.; 



Figure 54. — Anolis cyholes longilibialis: a. Top of head; b, side of head; c, middorsal scales; 

 d, side of tail. U.S.N.M. No. 83880, from Beata Island, Dominican Republic. Two 

 and one-half times natural size. 



snout to center of eye, 12 mm.; width of head, 12 mm.; foreleg, 29 

 mm.; hindleg, 52 mm.; tibia, 18 mm. 



Color (in alcohol): Olive-gray above, lightening to drab on tail and 

 limbs; below lilac-gray on throat and belly, olive-buff on legs and tail; 

 some small brown spots in a transverse series above the shoulder, 

 and a few scattered dots on the occiput and back ; upper proximal sur- 

 face of tail with a few median brown spots; skin of dewlap lilac-gray, 

 the scales white. 



Variations. — From the examples before me, no adequate concept of 

 the variation of this form may be obtained. No. 83878 is much like the 

 one described above, differing chiefly in the lesser degree of spotting. 

 The same coarse dorsolateral granules occur in both specimens, and 

 this character alone is probably sufficient to separate this subspecies 

 definitely from its representative on the mainland of Hispaniola, Anolis 

 cybotes cybotes, great as the variation undoubtedly is in the latter 

 species.
