Type-specimens.— USNM 201602 (holotype), USNM 201601 (3 

 paratopo types), and UMMZ 187096 (1 paratopotype), collected from 

 the lower portion of Abrams Creek, Great Smoky Mountains National 

 Park, June 8, 1957, by Eugene W. Whitney and party. 



Diagnosis. — Noturus (Rabida) baileyi is a member of the hilde- 

 brandi species group, which is characterized by typically eight pelvic 

 rays, a short caudal fin, short to almost obscure anterior serrae of the 

 pectoral spine, and a very short posterior process of the cleithrum 

 (humeral process). The color pattern of baileyi, in preservation, is 

 somber, more so than in any other species of Rabida. The back and side 

 of the head and body are almost uniformly pigmented, without 

 blotching and the dorsal saddles are small. Like the typical southern 

 subspecies of Noturus hildebrandi there are 1 1 preoperculomandibular 

 pores and the head is large but generally unlike hildebrandi, the anal 

 fin is very short with 12 or 13 rays and there are only 7 or 8, modally 8, 

 soft pectoral rays. 



Description. — Counts and measurements are given in tables 17 to 

 23 and 25 to 26. Head relatively large, rounded above, only slightly 

 deeper than caudal peduncle; greatest body depth beneath dorsal fin; 

 caudal peduncle tapering slightly posteriorly, not prominently con- 

 stricted; mouth subterminal, with lower jaw only slightly included, 

 less so than in any other species of Rabida; eye moderate, 1.8 to 2.1 

 times in snout; pectoral spine only slightly curved, relatively straight 

 for a Rabida; anterior serrae fine, numerous; posterior serrae moder- 

 ately large, recurved toward spine base, four or five in all specimens; 

 dorsal spine stout, relatively short, about 2/5 length of longest dorsal 

 ray; posterior process of cleithrum short, acute, its length less than 

 half diameter of pectoral spine shaft; premaxillary teeth in a small 

 rectangular cross band with posterior corners smoothly rounded; 

 adipose fin higher than the short anterior upper procurrent caudal 

 rays, without a notch between them; caudal fin of moderate length, 

 nearly truncate posteriorly; barbels all very short.
