Eye small. Snout scarcely prominent. Rostral about once and 
a half as broad as deep, the portion visible from above measuring

internasals shorter than that between the prefrontals; frontal con- 
siderably longer than broad, as long as or longer than its distance 
from the end of the snout, shorter than the parietals ; loreal longer 
than deep; one pre- and two postoculars ; temporals 1+ 2 or 2+3; 
seven upper labials, third and fourth entering the eye; four lower

frontals ; frontal a little longer than broad, as long as its distance 
from the rostral, shorter than the parietals ; loreal twice as long as 
deep ; one pre- and two postoculars ; temporals 2+; seven upper 
labials, third and fourth entering the eye; four lower labials in 
contact with the anterior chin-shields, which are longer than the
