Bull-head {Ameiurus melas, Raf.). 



The most common of the small catfishes in the sloughs. 

 They seem to be gregarious when young and small schools 

 were occasionally 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 (^)uincy, 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. 



Harkness Slough, one large example ; Moss Lake, several 

 large examples ; slough south of <,)uincy, a few. 



Willow Cat, Channel Cat, White Fultux {Ictalurus jjunc- 



tatus^ Kaf.) 



Young 5 to 7 inches long were frequent in some of the 

 sloughs and were quite abundant in Bear Creek. No large ex- 

 amples were seen in the sloughs, but specimens weighing irom 

 a half to three quarters of a pound were abundant in the river, 

 as was seen by the numbers caught on trot lines. The young 

 are called "fiddlers" by fishermen. 



Localities: Bear Creek, Dead Man's Slough, Willow 

 Slough, Long Lake, Broad Lake, Wood Slough. 



Family Amiid.e (Dog-Fisii.) 

 Dog fish {Amia calva, Linn.) 



Young dog-fish were not often seen in the pools outside 

 the levee, but inside they were everywhere common. They 

 measured from six to eight inches in length. In Bear Creek 

 they were especially abundant, sometimes sporting at the sur- 

 face in great numbers. Adults were also taken inside the 

 levee. They certainly spawn on flooded bottom-lands in early 

 spring; and I can account for their almost total absence from 

 the temporary pools only by supposing that the young follow 

 the adults into the deeper waters as the bottom-lamls become
