The head is contained 2^ times in the trunk to the vent, and 5 times 

 in the entire length. The body is not much compressed, and the head 

 and neck not at all. The depth of the body is a third of the length of the 

 head. The gape does not quite extend to the posterior part of the eye, and 

 is a fourth of the length of the head. The jaws are straight and capable of 

 being completely .closed. The teeth are sharp and easily detached. They 

 are biserial in the upper jaw, with a group of enlarged curved teeth in 

 front. There are no teeth on the shaft of the vomer running back between 

 the lateral teeth. In the lower jaw the teeth are uniserial on the side and 

 biserial toward the front. The eye is contained lys times in the length 

 of the snout, and 8 times in the head. The snout is broadly rounded as 

 viewed from above. The anterior nostril is in a tube, and the posterior one 

 is in the upper lip, opening downward, and not visible in a side view. 



The dorsal fin begins a distance behind the gill opening equal to the 

 length of the snout. The longest rays are toward the posterior end of the 

 dorsal, where their length is contained 2^ times in the length of the head. 



The ground color is light, but made almost uniform dull brown by 

 dark points which more or less run together. On the back and side this 

 is scarcely appreciable except with the aid of a lens, appearing to the 

 unaided eye uniform brown, but on the belly the points are better separated,
