CATFISH GENUS NOTURUS RAFINESQUE 173 



N. placidus is a riffle fish, living under rocks, in large gravel, or in 

 cavities; it probably prefers clear water. It was taken easily in the 

 upper Neosho River by literally shoveling gravel out of a riffle onto 

 the bank and removing the catfish from the substratum. Mr. J. Clark 

 Salyer collected the species by turning stones and seining with a 

 heavily weighted seine up the riffle from which the stones had just 

 been removed. It is of interest to note that Salyer collected his speci- 

 mens from beneath large stones, I have collected them chiefly from 

 gravel, and Dr. George A. Moore reports that in the Illinois River 

 he found them over a fine sand bottom \vith mud and decaying matter, 

 but which was barren of plants. 



N. placidus seems to be confined to riffles in the main channels of 

 the larger rivers. No specimens have been obtained from creeks or 

 the small to moderate size tributaries of the Neosho or Illinois Rivers.
