Diagnosis. — Noturus (Rabida) elegans is characterized by an elon- 

 gate anal fin with 14 to 19 rays, small spines with short anterior 

 serrae, a short posterior process of the cleithrum, and typically 9 

 pelvic rays. 



It has 46 to 55 caudal rays; 8, sometimes 9, soft pectoral rays; 

 normally 11 preoperciilomandibular pores; and 2, infrequently 1, 

 internasal pores. The body is moderately elongate; the caudal and 

 adipose fins are united, but the fins are low at the junction; the soft 

 dorsal rays, except near the dorsal fin base, are without dark pigment. 



It is distinguished from members of the miurus and furiosus species 

 groups by color pattern, shorter spines and posterior process of the 

 cleithrum, and the connection of the adipose and caudal fins; from 

 Noturus eleutherus by small spines, wide union of the caudal and adi- 

 pose fins, and eleven rather than ten preoperculomandibular pores;
