Description.—Body not much elongate, usually rather deep and chubby, sometimes ex- 
tremely so; head wide and flattish, not much longer than broad, the mouth very wide ; 
the lower jaw usually shortest, but sometimes the two jaws about equal when the 
mouth is closed ; dorsal region not much elevated ; anal fin very long, its base one-fourth 
or more the length of the body, of 24 to 27 rays; spines not very long; caudal fin 
truncate or slightly notched ; color normally dark yellowish brown, sometimes nearly 
black ; head 34 to 4.in length; depth 4 to 5; D.I, 6; A. 24to27. Length 1 to 2 feet. 
Habitat, Great Lake Region to Virginia, Florida, and Texas, generally abundant. 
Diagnosis—This is an extremely variable species as regards color 
and form. It is the only Ohio Cat-fish having a truncate caudal fin and 
more than twenty-three anal rays. Specimens from different waters 
vary much from each other. A very short, fat, chubby form is occasion- 
ally seen, which looks very unlike the ordinary form. Some of the lead- 
ing varieties have received special names, which it is not necessary to 
give here. 
Habits —This is one of the most abundant species of the lakes, ponds, 
and bayous of Ohio, being tolerably common throughout the State. It 
does not reach a very large size.
