Habit laccrtiform ; the distance between the end of the snout and 

 the fore limb is contained about once and one fourth in the distance 

 between axilla and groin. Snout moderate, obtuse. Lower eyelid 

 with an undivided transparent disk. Supranasal present ; fronto-

 prsefrontals forming a median suture ; frontal rather small ; seven 

 supraoculars ; ten supraciliaries ; frontoparietal single ; interparietal 

 distinct ; a pair of nuchals and a pair of temporals border the 

 parietals ; sixth upper labial largest, below the eye. Ear-opening 

 moderately large, roundish, without lobules. 37 smooth scales 

 round the middle of the body ; laterals a little smaller than dorsals 

 and ventrals. Marginal praeauals scarcely enlarged. The hind limb 

 reaches nearly the axilla. Digits moderate, subdigital lamellae 

 smooth. Tail nearly once and one third the length of head and
