Head much depressed ; snout slightly longer than the diameter 

 of the orbit ; nostril lateral, below the canthus rostralis, slightly 

 tubular. Upper head-scales smooth ; occipital not enlarged ; small 

 closely set spinose scales on the head near the ear, and on the neck ; 

 ear entirely exposed, larger than the eye-opening. Throat strongly 

 plicate ; no guJar pouch. Body depressed, with a more or less 

 distinct fold on each side of the back ; scales on the neck and sides 

 small, smooth or very feebly keeled, uniform, those on the vertebral 

 region enlarged, equal, roundish-hexagonal, imbricate, smooth or 

 very feebly keeled ; ventral scales smooth, a little smaller than the 

 enlarged dorsals. Limbs strong, with compressed digits ; the scales 

 on the upper surface large and strongly keeled ; fourth finger 

 slightly longer than third ; fourth toe considerably longer than 

 third, the extremity of the claw of the latter not reaching the base 

 of the claw of the former ; fifth toe extending beyond first. Tail 

 rounded, much depressed at the base, covered with moderate-sized 

 strongly keeled scales arranged in rings ; its length equals twice 

 and a half to three times the distance from gular fold to vent. 

 Males with a double or triple row of anal pores. Olive above, 

 marbled with black, and generally with round light spots pro- 

 ducing a network ; sometimes the black spots forming a festooned 

 band on each side of the vertebral line ; the male's throat marbled 

 with blackish.
