Cope states that the maxillary does not attain the line of the 

 orbit, which is only true when the mouth is closed, as the 

 distal portion seen when the mouth is closed is not the end, 

 though even then it is very close. The pharyngeal teeth are 

 said to be more or less crenate and the inference according 

 to his key is that they would be 4-4. The external angle of 

 the pharyngeal bone is said to be scarcely projecting.

Body moderately elongate, well compressed, profiles sim- 

 ilar and greatest depth at dorsal origin. Caudal peduncle 

 compressed, least depth about 2 1/5 its length. Head moder- 

 ate, muzzle obtuse. Snout convex over surface, length 2/3 

 its width, very slightly protrudes beyond lower jaw. Eye 

 large, deeply ellipsoid, high, its center about first 3/8 in head 

 length. Mouth little inclined, moderately large. Lower jaw 

 slightly included in upper jaw and with slight prominence at 

 symphysis below. Premaxillaries protractile downward. Max- 

 illary reaches very slightly beyond front of eye, though when 

 closed appears to barely attain to it. Jaw edges tough, firm, 

 little trenchant. Tongue adnate, fleshy. Nostrils near upper 

 front of eye, hind one crescentic. Interorbital broad, very
