Var. with ten sets of rings, and the postocular cross-band interrupted by 

 the black ground on the temporal region. It resembles the dissoleucus* 

 slightly, but wants the acute, prominent muzzle, and small rostral plate of that 

 species. The labials are not so elevated as in that species, and lemnis ca- 

 t u s and other allies, the fourth (subtending the orbit) being as long as high. 

 The prefrontals are not so small, relatively, as in dissoleucus, but are 

 more as in lemnis cat us, where they are smaller than in pyrrhocryp-
