 internasals somewhat smaller than prefontals, truncate in front, the 

 suture with rostral slightly longer than the suture of rostral with 

 first supralabial; prefrontals in contact with supraoculars; frontal 

 much broader than supraoculars, about as long as its distance from 

 tip of snout and as interparietal suture; parietals about as long as 

 distance of eye from tip of snout; nostril lateral, large, between two 

 nasals, of which the posterior is higher than the anterior; loreal 

 pentagonal, as high as long; two preoculars, the upper not in contact 

 with frontal; three postoculars; temporals 1 + 2, those of the second 

 row being abnormally fused oh the left side; 7 supralabials, fifth and

 two large oval apical pits same distance from the tip; 161 ventrals;
