 pointed ; loreal region nearly vertical. Lower eyelid scaly. 

 Nostril pierced in the centre of an undivided nasal ; no supra- 

 nasal ; no postnasal ; rostral widely separated from the fronto-

 with the frontal ; latter shield as long as its distance from 

 the posterior border of the parietals, in contact with the three 

 anterior supraoculars ; four supraoculars, first largest; seven

 as the interparietal ; parietals forming a suture behind the 

 interparietal; three pairs of nuchals; fifth and sixth upper 

 labials below the eye. Ear-opening smaller than the eye- 

 opening, with a large opercle-like scale on its anterior border. 

 24 smooth scales round the body, the two median dorsal and 

 ventral series largest. Two large prseanals. The hind limb
