 alius: M. V., 322 and 325 ; Bubalichthys alius, Bubalichihys 

 bubalinus.) 



A very abundant fish in the larger streams, and in the bottom 

 lakes ; this and the red-mouth being the species commonly shipped 

 under the name of "buffalo fish," from the Illinois and the other 

 larger rivers. They are among the most important commercial 

 fishes in our streams.

Mongrel Buffalo.

 rare.

(Bui. II, 65 ; Ichthyobus bubalus: Synop. 114 ; Ictiobus bubalus.)

112. Ictalurus furcatus, C. & V. 



Confined, in our experience, to southern localities, and taken by 

 us only in the Ohio. Not known in the Illinois Eiver, as far as I 

 am aware ; known to the southward, at least, as the channel eat or 

 blue cat. I have not taken this species in creeks. 



113. Ictalurus punctatus, Eaf. — Willow Cat ; Channel Cat ; White 



Cat. 



(Bui. II, 66 ; Ichthalurus punctatus, Ichthalurus robustus.) 



Abundant from the larger rivers, reaching a weight of from 20 to 

 25 pounds. 



Found in the deeper water of the Mississippi, Ohio, and Illinois, 

 and occurring likewise in the larger creeks connected with these 

 streams, and occasionally in overflow ponds in the river bottoms.
