{Snout wedge-shaped, -with angularly projecting labial edge ; 

 mouth inferior. Nostril close to the rostral, which is large and 

 nearly reaches the posterior border of the supranasals ; a small 

 anterior and a larger second loreal, the latter usually coalesced with 

 the prsefrontal on each side ; frontonasal rather large, one half or 

 two thirds the length of the frontal ; latter as broad as long or 

 slightly broader ; 3 or 4 very small supraoculars ; no supraciliaries ; 

 a prasocular ; interparietal as long as broad, as long as the frontal 

 or slightly shorter ; frontoparietals small ; parietals band-like, 

 narrow ; a pair of nuchals, in contact with the interparietal ; first 

 and second upper labials smallest, in contact with the nasal, fifth 

 much larger than the four anterior together. Ear hidden. Two 

 azygos postmentals. Body much elongate, with angular latero- 

 ventral edge, with two pairs of short tridactyle limbs ; the posterior 

 limbs proportionately much more developed than the anterior, and a 

 little longer than the distance between the fore limb and the anterior 

 corner of the eye. 22 scales round the body, those of the back and 

 of the two median ventral series narrower than the others. Two 

 slightly enlarged praanals. Tail shorter than head and body,
