The height of the body is contained four times and a fifth in the 

 total length (without caudal) , the length of the head thrice and two- 

 thirds ; head thick, snout obtuse. The diameter of the eye is more 

 than the length of the snout, two-thirds of the width of the inter- 

 orbital space, and contained thrice and one-third in the length of the 

 head. Dorsal and anal fijis of moderate size, the former not much 

 higher than long, the latter being considerably elevated. The origin 

 of the dorsal fin is midway between the root of the caudal and the 

 occiput, and corresponds to the fourteenth scale of the lateral line. 

 The first anal ray is below the third of the dorsal. Caudal rounded. 

 Mandible about as long as eye. Brownish olive above and on the 

 sides, silvery below ; fins immaculate. 



Males with nine or ten very distinct sUvery cross bars, each about 

 as broad as a scale. 



Females •with more or less numerous narrow black vertical stripes

The height of the body equals the length of the head, which is 

 contained four times and one-third in the total (with the caudal) ; 

 snout tapering ; the diameter of the eye two-ninths of the length of 

 the head. The dorsal fin is longer than high, higher posteriorly 

 than anteriorly, and its origin is nearer to the end of the snout than 

 to the extremity of the caudal. The tip of the anal extends further 

 backwards than that of the dorsal. Pectoral nearly reaching the 

 vertical from the base of the ventral. Yellowish brown, spotted 

 with black ; the spots corresponding to the scales, on the line of their 

 intersection. Dorsal and caudal spotted, anal immaculate, with the 

 margin blackish. (Girard.)
