Caudal fin conspicuously emarginate. Origin of the dorsal fin 

 niulway between the end of the snout and the root of the caudal. 

 1 he height ot the body is considerably less than the length of the 

 head, which IS one-fifth of the total (without caudal). The depth 

 ot the tree portion of the taU is one-half of its length. Snout ])ro- 

 duced rather pointed, its length being more than that of the post- 

 orbital portion ot the head. Eye of moderate size, its diameter being 

 a httle less than the width of the interorbital space. Length of the 

 pectoral fin rather more than one-half of the distance of its root from 

 the ventral. Upper margin of the dorsal fin straight, oblique. Body 

 mottled with blackish, the spots forming sometimes irregular bauds 

 across the back of the tail.

Caudal fin slightly emarginate. The origin of the dorsal fin is a 

 little nearer to the end of the snout than to the root of the caudal. 

 The height of the body is nearly equal to the length of the head' 

 which is two-ninths of the total (without caudal). Snout of mode- 

 rate length, obtuse, rather shorter than the postorbital portion of the 

 heail. Eye smaU. Length of the pectoral fin much more than one- 

 half of the distance of its root from the ventral. Upper margin of 

 the dorsal fin straight, oblique. Body with ten or twelve irrcguhir 

 brown cross bands, interrupted by the silvery lateral line. A black 

 streak from the eye to the end of the snout. {Heel.)

Caudal fin slightly emarginate. Origin of the dorsal fin neaily 



midway between the end of the snout and the root of the caudal". 



The height of the body is scarcely less than the length of the head, 



which is nearly one-fifth of the total (-nithout caudal). Snout short,' 



obtuse, much shorter than the postorbital j)ortion of the head. Eve 



rather small. Length of the pectoral about one-half of the distance 



of its base from the ventral. Upper margin of the dorsal fin straight,
