Ked-mouth Buffalo {Iciiohus cyprinella, C. & V.). 



Young 4 to 5.75 inches long were extremely common everywhere 

 in sloughs and lakes. They differ from the young of I. buhohis 

 in having a larger mouth, thicker body, and darker colors. The 

 pectoral and ventral fins are blackish, whereas in the case of the 

 quill-back buffalo they are pale. Most of the large buffalo taken 

 from the river were of this species.

Localities: Harkness Slough, Dead Man's Slough, Willow Lake, 

 Lily Lake, Long Lake, Broad Lake, Wood Slough. 



Morgan Cat, Yellow Cat {Leptops oUvaris, Eaf. ). 



This catfish was rare in sloughs and lakes. A single example 

 10 inches long from Willow Slough was the only one seen from 

 water of this kind. It was abundant in the river, where specimens 

 of ten pounds weight were frequently taken; and one was noted 

 August 6 that would probably have w^eighed 18 pounds or more." 

 I am informed that young dog-fish are used on trot lines as 

 bait for this catfish. 



BuLL-HEiD {Ameiurus melas, Raf.)- 



The most common of the small catfishes in the sloughs. They 

 seem to be gregarious when young and small schools were occa- 

 sionally seen swimming slowly along in an aimless fashion in the 

 bay. The examples taken measured from 1.25 to 2.75 inches in 

 length. Adults were not seen. 



Localities: Claus Lake, Wood Slough, Lily Lake, Long Lake, 

 slough south of Quincy, Quincy Bay. 



Bull Pout {Ameiurus nehulosus, Les. ). 



Not seen in most of the pools. Frequent and of large size in 

 Dead Man's Slough. 



Yellow Catfish {Ameiurus iiatalis, Les.). 



Not common. Those seen were adults. 



From: Harkness Slough, one large example; Moss Lake, sev- 

 eral large examples; slough south of Quincy, a few. 



Willow Cat, Channel Cat, White Fulton {Icialurus punda-
