Anolis bonairensis, new species 



Diagnosis : Tail moderately compressed, with serrated up- 

 per edge. Dorsal scales small, those of the vertebral region 

 larger than the laterals, smaller than the ventrals. Occipital 

 scale large, larger than the ear opening, in contact with the 

 scales of the supraorbital semicircles or separated from them 

 by a row of granules, surrounded laterally and posteriorly by 

 granules scarcely larger than the largest dorsals — at least 

 much smaller than the scales of the forehead; scales of the 

 supraorbital semicircles enlarged, separated or last one or two 

 pairs in contact ; supraocular scales enlarged, without keels. 

 Tibia much shorter than the distance between end of snout 

 and ear opening. 



Habitat : Bonaire and Klein-Bonaire, Dutch Leeward Is- 

 lands.

Description of Type Specimen : Head moderate, about once 

 and a half as long as broad, the length to the posterior border 

 of the orbit equal to the length of the tibia ; the hind limb ex- 

 tended forward reaches the temporal region. Snout rather 

 strongly depressed, forehead concave, no frontal ridges. Up- 

 per head scales smooth, scales of the supraorbital semicircles 

 large, last two pairs in contact with each other and the occipi- 

 tal scale ; about ten enlarged smooth supraoculars ; loreal rows 

 three ; occipital scale large, surrounded laterally and posterior- 

 ly by granules scarcely larger than the enlarged dorsals, much 

 smaller than those of the forehead ; dorsal scales small, keeled,
