 truncate and projecting ; rostral nearly as deep as broad, visible 

 from above ; internasala one half to two thirds as long as the prse- 

 frontals, which are more than half as long as the parietals ; frontal 

 as long as broad, or a little longer, as long as its distance from the 

 rostral or the end of the snout, a little shorter than the parietals ; 

 loreal very elongate ; one large prteocular, in contact with the 

 frontal; two postoculars ; temporals 2 + 3; nine to eleven upper 

 labials, two (rarely three) of which (fifth and sixth or sixth and 

 seventh) enter the eye ; six lower labials in contact with the ante- 

 rior chin-shields, which are much longer than the posterior. Scales

 keel, 233 to 263; anal divided; subeaudals 122-149. Bright
