with a rather sharp edge on its downward and backward curve, its 
upper surface broader than long and nearly as long as the pre- 
frontals ; internasals shorter than the prefrontals; frontal nearly 
twice as long as broad, more than twice as broad as the supraocular, 
longer than the parietals and longer than its distance from the end 
of the snout ; nostril in a small trapeziform shield, separated from

broader than deep, barely visible from above, internasals about 
two-thirds as long as the prefrontals ; frontal about one and 
one-third as long as broad, shorter than its distance from the end 
of the snout, thrice as broad as the supraoculars, considerably
