worms, and mussels.” No specific reference to the use of 
mollusks as food by these game fishes has been noted else- 
where, although as bottom feeders, to a degree, one would 
expect them to use this class of animals for food. Forbes and 
Richardson (1909, p. 265) remark that little is known con-

The food of the Large-mouthed Black Bass is better known.
