circles large, continuous forward as frontal series, most 

 often separated between the orbits by a single series of 

 granules, occasionally in contact ; six to twelve enlarged 

 supraocular scales, smooth or with a faint keel, separated 

 from the supraorbitals by a single series of granules, some- 

 times in contact ; occipital about as large as the ear open- 

 ing, separated from the supraorbitals by two (one to three) 

 series ; canthus rostralis distinct, scales three or four j 

 loreal rows four to five ; seven to eight labials to below 

 the centre of the eye ; parietal granules enlarged, convex ; 

 ear opening small, vertically widest. Gular appendage 

 small, scales smooth or faintly keeled. Body slightly com- 

 pressed, a very low dorso-nuchal fold surmounted by sev- 

 eral rows of enlarged keeled granules. Dorsal granules 

 small, a little enlarged at the sides of the dorsal fold. Ven- 

 tral scales large, imbricate, faintly keeled, posterior margin 

 rounded. Anteferaorals larger, with low keels. Limbs 

 moderate, the adpressed hind limb reaches the orbit ; dig- 

 ital expansions rather small ; about twenty-four lamellas 

 under phalanges ii and iii of the fourth toe. Tail com- 

 pressed ; with a low crest of large subequal scales, those 

 marking the segments slightly larger; nearly twice the 

 length of head and body. Enlarged post-anal scales. 



Body uniform greenish to olivaceous blue, legs and head 

 brownish ; lighter beneath, clouded with brownish on the 

 chin, throat and anterior portion of the goitre. No white 

 spots. 



A small species, reaching the size of A. principalis. 

 Common on Marie Galante, whence our specimens were 

 brought by Mr. W. B. Richardson. 



Anolis lividus, sp. n. 



Head moderate, one and two-thirds to one and three-
