INTRODUCTION. 
The following list is believed to represent correctly our actual 
knowledge of the names and distribution of the fishes of Illinois at 
the present time. No species has been entered upon it of which I 
‘have not myself studied representative specimens, collected within 
the State, except a very few inserted upon the high authority of 
Dr. Jordan and of the curators of the Smithsonian Institution. 
My personal studies have been based entirely upon the collections 
of the State Laboratory of Natural History, made during the past 
eight years chiefly by myself and two of my assistants, Mr. W. H. 
Garman and Mr. N. K. McCormick. 
The waters in which these collections have been made, include 
Lake Michigan and several of the smaller lakes of Northeastern Ili-. 
nois; Rock River at Oregon; the Kishwaukee at Belvidere; Peca- 
tonica River and its branches at Freeport, and in that vicinity ; and 
the Galena River in the neighborhood of Galena. Many collections 
have also been made in Fox River at McHenry and Dayton; in the 
[llinois at Ottawa, Henry, Peoria, and Pekin, and at its mouth near 
Grafton; and from the lakes and ponds in the bottoms of these 
rivers at several of these points. The tributary of the Illinois most 
carefully searched is the Mackinaw, in Woodford and ‘Tazewell 
counties. A small creek in Hancock county was likewise thoroughly 
explored. In the southern part of the State our collections were 
taken from the lakes and ponds in the Mississippi bottoms of Union 
County; in Clear Creek and Drury Creek in the same vicinity; in 
Cache River and its tributaries near Vienna in Johnson County, and 
at Mound City; in the Wabash River at Carmi and Mount Carmel; 
and in the Little Wabash, the Embarras, and the Saline, and vari- 
ous tributaries of those streams. 
My knowledge of the fishes of the Ohio and Mississippi is de- 
rived almost entirely from several weeks’ collecting at Cairo and 
Mound City. i
