 dermal fold, unnotched and undivided on the median line, borders the 

 casque from shoulder to shoulder. There is neither a lateral nor a 

 parietal crest on the casque, nor dorsal, ventral nor gular crest on the 

 head and body. The whole surface of the body is covered with rather 

 small, subequal, polygonal, granular tubercles. On the snout there is 

 a large oblong dermal process covered with round granules. At a little 

 more than halfway between the eye and the dermal process there is, on 

 each side, an excrescence composed of a number of elongated tubercles 

 partially fused. The tail is of about the same length as the head and 

 body.
