and provided with small scales in its whole circumference, 

 except on the dorsal crest. 



The fore leg reaches, if laid backwards, to the loin ; it is co- 

 vered with keeled scales on the superior and anterior sides, with 

 granulations on the inferior and posterior. The inner finger is 

 not dilated, the fourth and fifth are of equal size. The hind leg 

 reaches, if laid forwards, to the anterior margin of the orbit j 

 it is covered anteriorly with keeled scales, all the rest being 

 granular. 



The ground-colour is now greenish-olive, in life apparently 

 greenish, shining golden and bluish; most of the specimens 

 have the sides of the neck and of the trunk and the posterior 

 part of the limb irregularly dotted with blackish-brown. One 

 of the females (caught with the male during the act of copula- 

 tion) has a broad dorsal streak, crossed by narrow black bars. 

 The lower parts are uniform yellowish-white. 



The females are only half the size of the males. All the females 

 had one egg only in the oviduct, those of the ovarium showing 

 no sign of development : it is very large compared with the 

 size of the animal; and there was no trace of embryo in it, 

 although it appeared to be ready for laying. This observation 

 seems to be in contradiction to the abundance of these Tree- 

 lizards ; but it may be possible that they breed several times in 

 every season, and that a single egg only is impregnated by one 

 act of copulation.

" The Anolis is exceedingly abundant, and its great familiarity 

 affords excellent opportunities of studying its manners; but 

 Mr. Gosse has already described the habits of the two Jamaica 

 species, A. iodurus and A. opalinus, so fully (Nat. Soj. pp. 216 

 et seq.), that we have little more to say of those of the present 

 than that they seem entirely to resemble the former : at any
