CATFISH GENUS NOTURUS RAFINESQUE 201 



instead it lives in areas of deposition, chiefly over a soft bottom. 

 For example, in the Hm^on River, Michigan, in riffles where N. 

 stigmosus and N. jlavus are most common, there are no residual 

 miurus, but that species occupies the same section of stream and the 

 habitats overlap below these riffles. Dr. George Moore states that in 

 Oklahoma miurus also lives in quiet pools with a mud bottom and an 

 abundance of detritus, such as leaves and twigs. Noturus miurus has 

 been taken in association with the following species of Noturus: 

 gyrinus, nocturnus, phaeus, exilis, jlavus, hildebrandi, albater, elegans, 

 eleutherus, munilus, and stigmosus.

Diagnosis. — Noturus (Rabida) flavipinnis of the miurus species 

 group has 54 to 62 caudal rays; 14 to 16 anal rays; and typically 2 

 internasal pores, 11 preoperculomandibular pores, 8 soft pectoral rays, 

 and 9 pelvic rays. The yellowish dorsal fin has a submedial band of 

 brownish pigment, but no black; a brown band crosses the caudal 

 peduncle; and the blotch of the adipose fin extends to the margin. 

 The spines, their serrae, and the humeral process are moderately long. 

 The adipose and caudal fins are united. No midcaudal crescent is 

 evident.
