Body elongate, limbs moderate : the distance between the end of 

 the snout and the fore limb is contained once and a half in the

 postnasal, and supranasal ; supranasals in contact behind the rostral ; 

 frontonasal rather small, broader than long, in contact with the 

 frontal ; latter a little longer than the frontoparietal, in contact with 

 the first and second supraoculars; four supraoculars, second largest, 

 fourth smallest ; seven supraciliaries, first largest : frontoparietals 

 fused into a single large shield ; interparietal distinct, small ; parietals 

 forming a short suture behind the interparietal ; a pair of nuchals and 

 a pair of temporals border the parietals ; sixth upper labial largest 

 and entering the orbit. Ear-opening as large as the eye-opening, 

 the anterior border denticulated. 32 (or 34) scales round the middle
