section, two sevenths of the length to the base of the caudal, almost equal 
greatest depth of body. Snout short, hardly as long as the eye, broad, very 
blunt; chin steep. Mouth wide ; lower jaws little longer, firmly joined ; upper 
shorter, protractile. Teeth conical, sharp, hooked, outer series larger. Eye 
large, little if any longer than the snout, two thirds of the forehead, two 
sevenths of the head. Dorsal origin nearly midway from occiput to tip of 
caudal, hardly as far forward as first anal ray, hind end of base a trifle 
farther back than that of anal. Ventrals small, not reaching anal. Pec- 
torals small, hardly reaching bases of ventrals. The length of the caudal 
pedicel from the origin of the dorsal to the bases of the median caudal rays 
is about the length of the head; the depth is two thirds as much. Caudal fin 
nearly as long as the head, rounded. Genital tube of female extended 
a little in front of the anal, the anterior rays of which have a fold at each 
side of their bases. 
Olivaceous, yellowish, golden or reddish, to brownish or blackish; back 
and top of head darker; opercle silvery. With or without eight to sixteen 
vertical bars of brown on the flanks. Dorsal, anal, and caudal plain, or 
clouded, or having more or less regular transverse series of dots. Some 
specimens have a light streak on each scale, forming longitudinal streaks on 
the flank. Many are freckled with golden, silvery, or light colored scales, in 
cases forming lines. Others have freckles of brown, on single scales, scat- 
tered over the body. Rarely a silvery band passes back from the opercles. 
Frequently a light spot is present on the crown. A few are profusely 
blotched with black or brown. Occasionally indications of darker longi- 
tudinal bands are present. Reaches three inches and a half, or more.
