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 creature, 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 (Bombyx) 
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 (Barbour); 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. lizards Brit. mus., 1885, 2, p. 42). He considered Anolis 
argillaceus Cope a synonym of this species and probably concluded from Cope’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.
