Body and limbs moderately elongate in the male, the body longer 

 and the limbs weaker in the female ; head depressed. Frontonasal 

 large, broader than long, seven-sided ; praefrontals forming a short 

 suture ; frontal very small, pentagonal ; parietals rather small ; 

 interparietal large, subpentagonal, longer than parietals ; a very 

 large supraciliary, forming an oblique suture with the unique supra- 

 ocular which forms a suture anteriorly with the smaller prafroutal; 

 a loreal ; seven or eight upper and six or seven lower labials ; chin- 

 shields, one anterior and two pairs forming a suture. Scales on the 

 body perfectly smooth ; fifteen round the body, and thirty-four { S) 

 to thirty-eight ( $ ) from occiput to base of tail. Four femoral 

 pores on each side, in males. Tail cylindrical, tapering, covered 

 with rounded scales which, except at the base, are feebly keeled ; 

 the portion of the tail which has been reproduced is no longer 

 covered with rounded scales, but with overlapping whorls of lanceo- 

 late scales, exactly similar to those of Heterodactylus and allies. Dark 

 olive above ; a yellowish, black-edged band on each side, beginning 

 from the tip of the snout ; another, narrow, parallel line along the 

 upper lip, through the ear-opening, and over the fore limb, to groin ; 

 tail pinkish posteriorly ; throat and belly grey, black-dotted.

In most respects similar to the preceding ; the difference of pro-

 scales round the body, and thirty-one ( c? ) or thirty-seven ( cJ ) from 

 occiput to base of tail. Male with three or four femoral pores on
