The height of the body is contained four times in the total length 

 (without caudal), the length of the head four times and one-third. 

 Eye rather small, one-fifth of the length of the head, occupying its 

 middle. Teeth sub-truncated, with brown tips. The origin of the 

 dorsal fin is a little nearer to the extremity of the snout than to the 

 root of the caudal fin. The pectoral terminates at a great distance 

 from the ventral. Brownish green above, yellowish below ; a broad 

 black band, occupying one series of scales and two halves, runs from 

 the gill-opening, immediately below the lateral line, to the root of 

 the caudal. Fins immaculate.

The height of the body is more tnan the length of the head, which 

 is two-ninths of the total (without caudal) ; the eye is one-fourth 

 of the length of the head, and occupies its middle. The origin of 

 the dorsal fin is nearer to the extremity of the snout than to the 

 root of the caudal. The pectoral terminates at some distance from 

 the ventral. A blackish band runs from the angle of the mouth 

 along the lateral line to the posterior margin of the caudal ; a second, 

 more indistinct, from above the gill-opening to the adipose fin ; a 

 'hird, also indistinct, from the occiput to the dorsal fin. (Kner.)
