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 and 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.

with more or less distinct light brown longitudinal streaks; a dark 
brown streak on each side of the head, beginning from the nostril
