Rostral broader than deep; internasals shorter than the prae- 

 frontals ; frontal as long as broad or a little broader than long ; 

 shorter than its distance from the end of the snout, much shorter 

 than the parietals, in contact with the upper praeocular ; two or 

 three prseoculars, with a subocular below them, the latter sometimes 

 fused with the third labial ; two or three postoculars with a sub- 

 ocular below them ; two very large temporals, the upper longest 

 and in contact with the entire outer border of the parietal, the 

 lower usually descending to the lip, between the sixth and seventh 

 labials ; the large upper temporal separated from its fellow on the 

 other side by three occipital shields ; seven or eight upper labials, 

 fourth (or third and fourth) entering the eye, second ^nd third 

 much deeper than third and usually both, sometimes only the second, 

 in contact with the prsefrontals ; four lower labials in contact with 

 the anterior chin-shields, which are as long as or shorter than the 

 posterior. Scales in 13 rows, outer much shorter than the others, 

 one dorsal scale corresponding to two laterals or to two ventral 

 shields, Ventrals 211-225; anal divided; subcaudals 107-119, 

 'OUve-green above, uniform or each scale brown at the end ; Lead-
