44. Golden Ked Horse. Myxostoma aureolum, Le S. (2.) Chiefly 

 moUusks, (Anodonta, Paludina}, a few slender ringed worms (Naididae), 

 niucli dirt and a little unrecognized vegetation. 



45. Myzostoma, sp. undet. (3.) Only mud and Unionidae. 



46. Chuh Sucker. Eremyzon sucetta, Lac. (2.) Confervoid algae, 

 diatoms, mud. 



47. Carp Suckers. Carpiodes, sp. (6.) I have found it quite im- 

 possible to recognize the species of this genus with certainty by the descrip- 

 tions extant, and until they have been revised prefer not to attempt to sep- 

 arate them.

CAT FISHES. SILURIDAE, [8.) 



Very miscellaneous feeders, eating both animal and vegetable food, the 

 former the more freely. Bones and pieces of fish were found, evidently 

 from too large animals to have been swallowed alive. Aquatic larvae of all 

 kinds, worms, water bugs, mollusks (rarely;, algae, stems and leaves of both 

 exogens and endogens, masses of fine roots, with an occasional craw-fish 

 make up the bill of fare. 



50. Common Channel Cat. Ichthaelurus punctatus, Raf. (6.) Bones 

 and pieces of large fishes 3, fragments of bivalve mollusks (no shells) 1, 

 land insects 1 (bees, plant bugs), aquatic larvae 6 fDytiscidae, Agrioninae
