 small closely-set spinose scales on the sides of the head near the 

 ear, and on the neck ; ear entirely exposed, larger than the eye- 

 opening. Throat strongly plicate ; no gular pouch. Body de- 

 pressed, with a more or less distinct fold on each side of the back ; 

 scales on the neck and sides minute, almost granular, keeled, 

 uniform or intermixed with scattered enlarged scales ; those on 

 the vertebral region enlarged, equal, rhomboidal, imbricate, strongly 

 keeled ; a very slight indication of a nuchal denticulation ; ventral 

 scales smooth, nearly as large as the enlarged dorsals. Limbs 

 strong, with compressed digits ; the scales on the upper surface 

 of the limbs much enlarged and very strongly keeled ; third and 

 fourth fingers equal, or fourth very slightly longer; fourth toe 

 slightly longer than third, fifth extending beyond first. Tail 

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

 strongly keeled scales arranged in rings ; its length equals 2^ to 

 3 times the distance from gular fold to vent. Males with a large 

 patch of thickened praeaual scales and a patch of similar scales on 

 the middle of the belly. Olive-brown above, spotted or speckled
