This species has the dorsal scutellatiou characteristic of the sub- 
genus Pantodactt/fuft ; hnt, as befnre remarked, the dorsal scales are 
still narrower than in Cercosaura schreibersu:, and more hke those 
of a argutun, Peters, figured in 'Ahh. .\k. Berl/ lyfi:^, pi. i. fig. 3. 
The narrow rounded ventral scales are a peculiar feature ; and so also 
is the arrangement of the parietal head-sliields, which is like that of 
the genus Leposoma.
