 The height of the body is equal to the length of the head, which 

 is about one-fourth of the total (without caudal). Snout as long as 

 the eye, the diameter of which is two-sevenths of the length of the 

 head. The origin of the dorsal fin is opposite to that of the ventrals, 

 and scarcely nearer to the end of the snout than to the root of the 

 caudal fin. Pectoral fin terminating at some distance from the ven- 

 trals. There are three longitudinal scries of scales between the 

 lateral line and ventral fin. Coloration uniform.
