Anolis loysiana is by no means a common lizard or at least it is by no means 

 easy to find. It is a curious looking, rather sluggish, flat little creatiire, relying 

 upon its wonderful protective coloration to escape notice. It is found usually 

 upon the rough grayish bark of trees and on bark like that of the Ceiba (BombjTc) 

 it is literally invisible unless it moves. The example described from Los Negros 

 in the Sierra Maestra was taken upon gray limestone, the rocky bank cut down 

 by a rapid torrent (Barbom*) ; two examples from Bayate, Oriente (Ramsden), 

 and one from San Diego de los Bafios (Palmer and Riley) are important in that 

 they show that the spine-like scales are not confined to the males as stated 

 by Boulenger (Cat. hzards Brit, mus., 1885, 2, p. 42). He considered Anolis 

 argillaceus Cope a s;^Tionym of this species and probably concluded from C'ope's 

 description being in some respects similar, but mentioning no spines, it repre- 

 sented the female of A. loysiana. As a matter of fact it is not very closely 

 related; loysiana is found, as stated by Gundlach, all over Cuba wherever 

 forested areas offer a suitable habitat.
