strongly plicate ; no gular pouch. Scales on the back of the neek

 middle of the back ; these are considerably larger than the scales of 

 the sides, being about twice as broad ; latter distinctly keeled, with 

 a few conspicuously larger scales scattered amongst them ; ventral 

 scales smooth, about the same size as those of the middle of the 

 back. Limbs long and strong, covered above with strongly keeled 

 scales ; digits as in the preceding. Tail rounded, covered with 

 keeled scales ending in a short spine posteriorly, all in verticils, the 

 largest scarcely larger than the largest dorsal scales. Males with 

 two or three rows of anal pores. General colour pale yellowish, 

 mixed with dusky black ; chin and throat dusky, more or less 

 mottled or speckled with pale yellow.

Head much depressed ; snout longer than the diameter of the 

 orbit ; nostril lateral, below the canthus rostralis, slightly tubular. 

 Upper head-scales smooth or feebly keeled ; occipital not enlarged ; 

 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 depressed, 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 inter- 

 mixed 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 com- 

 pressed digits ; the scales on the upper surface of the limbs strongly 

 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 twice and a half to three times the 

 distance from gular fold to vent. Males with a large patch of anal 

 pores and a similar patch of pores on the middle of the belly. 

 Olive-brown above, spotted or speckled with blackish, sometimes 

 with small yellowish spots ; the breeding male's throat blue, with
