elevated. Head moderately small, conic, depressed below, and 
less so above where slightly convex. Snout rather long, largely 
convex above, its length about 24 its width, and when viewed 
above with rounded truncate tip to constrictions of sides. Eye 
elongate, not much elevated over upper profile, placed a little 
nearer tip of snout than shoulder, or about over first 34 in gape 
of mouth. Mouth large, gape a little convex in profile with con- 
vexity superior. Lips thin, and most all of upper overlapping 
edge of mandible when mouth closes. Lower lip very firm, or 
hardly developed. When viewed below mouth rather triangular, 
so that it would be isoceles, though tip broadly and convexly 
rounded, with more truncated profile of snout protruding well

beyond. ‘Teeth fine, short, firm, more or less even, and in nar- 
row or single series in upper jaw. Apparently no mandibular 
teeth. Vomerine teeth minute, in form of 2 small separate 
patches on each side of median line, though close to one another 
and between internal nares. ‘Tongue large, ovoid, with bulge 
posterior, and posterior margin with a rather deep median in- 
cision. Sides and posterior part of tongue all free, and its sur- 
face minutely and densely papillose. Internal nares placed equi- 
distant to edges of bony interorbital width. External nostrils 
rather conspicuous above on sides of snout, a trifle nearer its tip 
than eye, and internasal space about equal to that of bony inter- 
orbital. Internasal and interorbital spaces nearly evenly level or 
with but slight median depression. Loreal region slightly con-
