Snout wedge-shaped, with projecting labial edge ; eye very small ; 

 ear-opening appearing as an oblique slit at the commissure of the 

 mouth, covered with a fringe of three or four pointed scales. 

 Nostril pierced entirely in advance of the suture between the 

 rostral and the first labial ; a small postnasal, in contact with the 

 first aud second labials ; supranasals united into a single shield ; 

 frontal as broad as or a little broader than long ; fourth labial 

 entering the orbit. Body much elongate ; sides of belly angular. 

 Scales perfectly smooth, 24 round the middle of the body. Limbs 

 weak, penta- or tetradactyle, the hind pair proportionately more 

 developed than the front pair ; the length of the fore limb equals 

 half its distance from the centre of the eye, that of the hind limb 

 about the distance between the nostril and the fore limb. Tail 

 about four fifths the length of head and body. Yellowish above, 

 with more or less distinct light brown longitudinal streaks ; a dark 

 brown streak on each side of the head, beginning from the nostril 

 and passing through the eye ; lower surfaces white.
