diameter of the eye ; the portion seen from below longer than 
broad and slightly narrower behind than in front. Nasals apparently 
fused with the first supralabial of each side, in contact behind the 
rostral ; a little shorter than the praefrontals, their suture being the

same length as that of the praefrontals. Nostril large, not visible 
from above ; a very distinct groove runs from its posterior edge to 
the lower anterior border of the praefrontal. Praefrontals a little 
larger than the nasals, a little more than half the length of the 
frontal, forming a suture in the median line and with the first 
supralabial (the second supralabial if we count the first as fused 
with the nasal). Frontal six-sided ; broader in front than behind; 
almost once and a half as long as broad, as long as its distance from 
the end of the snout. Supraocular narrow, extending down behind 
the eye and meeting the third supralabial. A pair of parietal 
shields larger than the adjoining scales, in contact behind the eye 
with the third supralabial. A small praeocular ; no postocular.
