smallest scales of the body are observed under the chest. The soft portions of the dorsal and 
anal fins, as also the caudal, exhibit numerous small and polygonal scales. 
The ground color of the body is reddish brown, of a lighter hue beneath than above. The 
fins are olivaceous or greyish, an obsolete dark spot being occasionally observed upon the pos¬ 
terior margin of the base of the dorsal. The opercular flap is jet black, margined with a light filet. 
The sides of the head exhibit irregular or meandric bluish (as preserved in alcohol) lines.

The “ striped bass” or “rock fish” of the Atlantic coast, as well as the “ white perch” 
or “ little white bass ” of our ponds and rivers, both belong to this genus. 
They are fishes familiar to all, at least in an esculent point of view. The species described 
below is one of rather small size when compared to the “striped bass” or “rock fish,” 
although it is larger than the “ white perch.” 
So far the fresh water species of this genus have not been observed further west than the basin 
of the Mississippi, and none of them have as yet been noticed along the Pacific coast.

beneath.
