 River., Mo., La Mine River, Mo., and Hundred and Two River at Bedford, 

 Iowa, and Mary ville, Mo. ; Blackwater Creek, Brownsville, Saline County,

 Iowa (Meek, 1892); Missouri River, Craig, Mo. (Eigenmann, 1894); Salt 

 Creek, Lincoln, Nebr. (Meek, 1894). It was found by us at the followiug 

 places: Emanuel Creek, Springfield; Norfolk Creek, Norfolk Junction ; Elk- 

 horn River, E wing ; Beaver Creek, York ; Lincoln Creek, York ; Platte River, 

 Grand Island; Middle Loup River, Dunning; Chadron Creek, Chadron; 

 White River, Chadron ; Cheyenue Falls ; Belle Foarche River, Belle Fourche ; 

 Beaver Creek, Buffalo Gap ; Platte River, Douglas ; Beaver Creek near New- 

 castle; Powder River, Arvada; Big Goose Creek, Sheridan, and Salt Creek, 

 Lincoln. Quite abundant in the south fork of the Cheyenne at Cheyenne 

 Falls, where numerous specimens, 5 to 10 inches long, were taken. It is said 

 to be a common hsli in the Cheyenne and is of some importance as a food- 

 fish. The specimens from Cheyenne Falls are all extremely pale. 



17. Schilbeodes gyrinus (Mitchill). Big Sioux River, Sioux Falls, S. Dak. (Meek, 



1892); Platte River, Fremont, Nebr.; Floyd River, Lemars and Sioux City, 

 Iowa (Meek, 1894); Choteau Creek, Springfield; Prairie Creek, Scotland; 

 Enemy, Firesteel, and Rock creeks, Mitchell; Norfolk Creek, Norfolk Junc- 

 tion. 



This small catfish appears to be not uncommon about Mitchell and Scot- 

 land, but we did not find it elsewhere except at Norfolk Junction, where a 

 single specimen was obtained. The largest specimens secured by us are 4 

 inches long, and are very plump. The head is very broad and heavy. The 

 interorbital region is concave, especially posteriorly, the postocular region 

 being quite fleshy and prominently rounded. The pectoral spine is equal to 

 one-third of the distance from the tip of the snout to the origin of dorsal fin. 

 Most of these specimens are very dark, but the dark lateral lines show 

 plainly on all. These lines are three in number, one following the axis of 

 the body from just back of the pectoral to the middle of the base of the 

 caudal fin, another above from the dorsal fin to the caudal; the median line 

 of the back also is dark. 



18. Schilbeodes exilis (Nelson). Osage River, etc. (Graham, 1885); Jones Creek, 



Dixon, Mo., and Little Piney River, Cabool, Mo. (Meek, 1891). 



19. Schilbeodes miurus (Jordan). Branches of Missouri River (Graham, 1885). 



20. Ictiobus cyprinella (Cuvier & Valenciennes). Common Buffalo-fish. Missouri 



River, St. Josejm, Mo. (Jordan & Meek, 1885); eastern Kansas (Graham, 

 1885); Soldier Creek and Osage River (Cragin, 1885a); Marais River, Dixon, 

 Mo. (Meek, 1891) ; Elkhorn River, Fremont, Nebr. (Meek, 1894). Small speci- 

 mens were obtained in Platte River at Grand Island, in the Elkhorn at Ewing, 

 and iu the Middle Loup River at Dunning. The confusion which exists 

 among the species of Ictiobus and Carpiodes is very great and it is doubtful 

 if any of the descriptions given in the books is correct. The species as now 

 understood are certainly hard to distinguish, and the confusion can only be 

 removed by an exhaustive study of a very large amount of material.
