Diagnosis. — Noturus (Rabida) miurus, of the miurus species group, 

 has 54 to 65, usually 57 or more caudal rays; 13 to 17 anal rays; and 

 typically 9 pelvic rays, 8 soft pectoral rays, 11 preoperculomandibular 

 pores, and a single internasal pore. A black blotch extends to the 

 margin of the adipose fin and another is present on the extremity of 

 the anterior dorsal rays, but the band of pigment on the procurrent 

 caudal rays extends little onto the caudal peduncle. The caudal and 

 adipose fins are broadly connected, and the spines and humeral 

 process are long. 



In combination, the more numerous caudal rays, the black tipped 

 dorsal fin, and the adipose blotch distinguish miurus from all but 

 species of the miurus group. The single internasal pore usually distin- 

 guishes it from all species of Rabida; the absence of a black bar crossing 

 the caudal peduncle distinguishes it from others of the miurus group; 

 and black in the dorsal fin segregates it ivoTujlamjpinnis. 



Description. — Other counts and measurements are given in 

 tables 17 to 26. Body heaviest just in front of dorsal spine; caudal 

 peduncle tapers backward; eye large, 1.1 to 1.8 in snout; head rounded
