Description. — Body oblong, compressed, becoming gibbous with age, the ante-dorsal 

 region more or less elevated in the adults ; the depth 3i iu length, ranging from 2i in 

 adults to 4 in young; head stout, short, about 4J in leugth (1 to 4^), the interorbital 

 space wide and depressed, the lower parts narrower, so that it is somewhat wedge- 

 shaped downward ; eye not large, 4J in head (4i to 5|) ; mouth protractile downward 

 and forward, the mandible oblique ; scales usually closely imbricated and more or less 

 crowded forward, but often showing various irregularities in arrangement, about 43 

 (39-45) in alogitadlual series and 15 (14 to 16) iu a transverse series between the ven- 

 trals and the dorsal ; fin-rays somewhat variable, the dorsal with 11 (10 to 13) developed 

 rays, the anal with 7, and the ventrals wiih 9 (rarely 8) ; coloration varying with age ; 

 never distinct series of black spots along the rows of scales ; young with a broad black 

 lateral band bjrdered above by paler; in some specimens from clear water, this band is 

 of a jet-black color and very distinct; in others, it is duller; later this band becomes 

 broken into a series of blotches, which often assume the form of broad trans irerse bars ; 

 in adult specimens, these bars disappear, and the color is nearly uniform brown, dusky
