Family LABRAC'IDiE. The Bass. 
We have but two species of this family, the white bass 
and the brassy bass ( Roccus chrysops and Morone inter- 
rupted . As far as their food is concerned, these are evi- 
dently equivalent species, agreeing closely in their gen- 
eral relations, and differing only in their distribution.
