DeaoripUon. — Body not mnch elongate, nsnally rather deep and chubby, sometimes ex- 

 tremely so ; head wide and flattlsh, not much longer than broad, the month yery wide ; 

 the lower jaw usually shortest, but sometimes the two jaws abont equal when the 

 mouth is closed ; dorsal region not much eleyated ; anal fin yery long, its base one-fonrth 

 or more the length of the body, of 24 to 27 rays ; spines not yery long ; caudal fin 

 truncate or slightly notched ; color normally dark yellowish brown, sometimes nearly 

 black ; head 3i to 4 in length ; depth 4 to 5 ; D. 1 , 6 ; A. 24 to 27. 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.
