REVIEW OF THE SEEKANIDiE. 
421 
The Yellow Bass is rather common in river channels and ponds in the southern 
part of the basin of the Mississippi. It reaches a length of about a foot, and is con- 
sidered a good food-fish. Our specimens are from St. Louis and from the White Water 
liiver, at Brookville, Indiana. 
As the name interrupta was given by Mitchill to a variety of Roccus Imeatus, a 
species of the same genus Morone, as then understood by us, the name Morone inter- 
rupta given to this species by Grill was replaced by a later name, mississippiensis. 
If, however, Morone and Boeews are regarded as distinct genera, the name interrnpta 
is tenable for a species of the former group.

Habitat. — Atlantic coast of the United States, from Nova Scotia to South Carolina, 
ascending streams and frequently laud-locked in ponds. 
Etymology. — Americana, American. 
This species is one of the most abundant and characteristic of the brackish waters 
and river mouths of our Atlantic coast. It is the smallest in size of the species of 
Morone, rarely reaching a length of a foot. It is a very excellent pan-fish, and it is 
everywhere known on the coast as the “White Perch.” Our specimens are from 
Wood’s Holl, New York, and Washington. Those from Wood’s Holl represent the 
variety called nigricans, very dark green in color, scarcely paler below, the body 
deeper* and the spines lower and shorter than in the common White Perch.
