Hypentelium nigricans (Lesueur). Northern hog sucker. Carter and 

 Jones (1969) reported this species from all three sites they sampled on 

 Buck Creek, and Harker et al. (1979, 1980) reported specimens from the 

 mainstem and Brushy Creek. The northern hog sucker was generally 

 distributed throughout all but the lower mainstem of Buck Creek and 

 was the most common catostomid in the drainage. Sites: 1(2), 5(2), 6(1), 

 7(1), 11(1), 12(9), 14(3), 15(1), 18(1), 21(1), 23(5), 24(11), 27(2), 29(2), 

 30(1), 32(5), 33(1). 



Ictiobus bubalus (Rafinesque). Smallmouth buffalo. Three speci- 

 mens of this typically large-river buffalo (Smith 1979) were collected by 

 gill net from the lower mainstem, where the species occurred sporadi- 

 cally. One specimen was retained (EKU 1190) and measured 39 cm SL. 

 Site: 38(3). 



Moxostoma anisurum (Rafinesque). Silver redhorse. One specimen 

 measuring 17.6 cm SL was collected from Buck Creek in 1954 by J. R. 

 Charles (UL 6865) (R. E. Jenkins, pers. comm.); however, exact locality 

 information was not recorded. Site: unknown. 



Moxostoma carinatum (Cope). River redhorse. Although the river 

 redhorse has been reported to inhabit medium-size rivers with gravel 

 and rock bottoms and swift or strong flow (Pflieger 1975; Smith 1979), 

 our specimens were collected from the sluggish lower mainstem, where 

 the species occurs sporadically. The specimen collected at Site 35 was 

 taken by gill net in 3.0 m of slowly flowing water over a bottom that 

 graded from mud and debris to rock. Sites: 35(1), 38(3). 



Moxostoma duquesnei (Lesueur). Black redhorse. Harker et al. 

 (1979, 1980) reported specimens of this sucker from the mainstem and 

 Brushy Creek. The black redhorse was occasional throughout the Buck 

 Creek drainage. Sites: 3(1), 11(1), 16(1), 24(-), 27(1), 35(2). 



Moxostoma erythrurum (Rafinesque). Golden redhorse. Carter and 

 Jones (1969) collected 112 specimens from three sites on the mainstem, 

 some of which were probably misidentified in light of the diverse sucker 

 fauna present in Buck Creek. This was the most generally distributed 

 and common Moxostoma in the drainage. Sites: 7(2), 18(2), 19(2), 21(3), 

 22(8), 23(8), 24(-), 27(4), 33(1). 



Moxostoma macrolepidotum (Lesueur). Shorthead redhorse. Only 

 one specimen of the subspecies M. macrolepidotum breviceps (CU 

 52283) has been collected from the drainage (R. E. Jenkins, pers. 

 comm.). Site: 32(1). 



Ictaluridae — bullhead catfishes 

 let alums fur catus (Lesueur). Blue catfish. Several specimens of the 

 blue catfish were collected from the lower mainstem, where the species 

 occurs occasionally. Site: 38(-).
