Casque somewhat more produced posteriorly than in C. pumilus, 
but otherwise similar as to shape and crests ; the latter with conical 
tubercles; the distance between the commissure of the mouth and 
the extremity of the casque equals or a little exceeds the length of 
the mouth ; a dermal lobe connects the occipital process with the 
back. Scales on back and sides very small and convex, with 
enlarged, roundish, flat, or subconical tubercles, the largest of which 
are irregularly scattered on the flanks; a crest of isolated, conical, 
slightly compressed tubercles along the back and tail; ventral 
scales often very unequal; no ventral crest; throat with enlarged 
tubercles; a series of very large, fringed scaly lobules along the 
throat, the anterior roundish, as broad as long, and overlapping. 
No tarsal process. Tail considerably shorter than head and body, 
usually about as long as the body ; none of the tubercles on the tail 
equal in size the largest ones on the sides of the body.
