Eye moderate ; snout short, truncate. Eostral just visible from 

 above ; internasals half as long as prsefrontals ; frontal once and 

 two thirds as long as broad, longer than its distance from the end 

 of the snout, shorter than the parietals ; loreal as long as deep ; two 

 praeoculars, with a small subocular below them ; two postoculars ; 

 temporals 1+2; eight upper labials, fourth and fifth entering the 

 eye ; four lower labials in contact with the anterior chin-shields, 

 which are much shorter than the posterior. Scales in 17 rows. 

 Ventrals 128-153 ; anal divided. The tail of the type specimen is 

 probably mutilated, hence the small number (42) of subcaudals. 

 Brown above ; a blackish lateral streak, running along the outer 

 ends of the ventrals ; lower parts orange. 



Total length 344 milUm.
