The snout forms half the length of the head ; its crest is composed of about 

 ten irregular teeth, and farther back are two others. The double frontal crest 

 is well dentated. The superior orbital border has five or six teeth. The ridge 

 under the orbit is unarmed, but on the side of the snout is well serrated. 

 The chin is prominent but unarmed, and some distance behind, in the middle 

 is a slight swelling. The longest superior pectoral rays are about equal to 

 the length of the operculum. The caudal is as long as the snout.
