The body is moderatelv slender and elongate, its greatest 

 depth equaling about two ninths of the total length without 

 tail, or somewhat less than the length of the head. The head 

 is flat above, the width between the eyes equal to nearly half 

 the length of head. The mouth is very protractile, small, its 

 width somewhat greater than the length of the lower jaw. The 

 upper jaw is as long as the eye, a little more than one fourth 

 the length of head, which equals about one fourth of total 

 length without caudal. The length of the dorsal base equals 

 the depth of the body and much exceeds length of anal base. 

 Length of longest dorsal ray less than one half of head; longest 

 anal ray two thirds of length of head. The dorsal is midway 

 between the tip of the snout and the root of the caudal. The 

 anal is wholly under the dorsal. Length of pectoral six and one 

 half times in total. Caudal large, convex behind. D. 14; A. 12.
