Description.—Body oblong, compressed, becoming gibbous with age, the ante-dorsal 
region more or less elevated in the adults; the depth 34 in length, ranging from 24in 
adults to4in young; head stout, short, about 44 in length (4 to 44), the interorbital 
space wide and depressed, the lower parts narrower, so that it is somewhat wedge- 
shaped downward; eye not large, 42 in head (44 to 54); mouth protractile downward 
and forward, the mandible oblique; scales usually clusely imbricated and more or less 
crowded forward, but often showing various irregularities in arrangement, about 43 
(39-45) in a logitudinal series aad 15 (14 to 16) in 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 with 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 bordered 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 transverse bars ; 
in adult specimens, these bars disappear, and the color is nearly uniform brown, dusky
