 groin. Snout rather elongate, obtusely acuminate, much depressed. 

 Lower eyelid scaly. Nostril pierced in the middle of a small 

 nasal ; a supranasal, rarely in contact with its fellow ; frontonasal 

 broader than long, usually in contact with the rostral, and fre- 

 quently also with the frontal ; latter as long as the frontoparietals 

 and parietals together or a little longer, in contact with the 

 first and second, or first, second, and third supraoculars ; 4 supra- 

 oculars, subequal in length ; 7 or 8 supraciliaries, first largest ; 

 frontoparietals and interparietal distinct, latter as large as former 

 or a little smaller, and entirely separating the parietals ; a 

 pair of nuchals ; 4 labials anterior to the subocular. Ear-opening 

 very small. 28 or 30 scales round the middle of the body, the 

 dorsals and laterals with 3 to 9 more or less strong keels ; nuchal 

 scales smooth or indistinctly keeled ; dorsals a little larger than 

 ventrals. Pneanals not enlarged. The adpressed limbs feebly 

 overlap, the hind limb never reaching beyond the wrist. Digits
