A. CATALOG-UE OF THE FISHES 
OF ILLINOIS. 
By Prof. DAVID S. JORDAN. 
This catalogue is based primarily on the collections in the Illinois 
State Laboratory of Natural History, at Normal. These collections con- 
sist (a) of the material on which Mr. Nelson’s* list was based, and (6) of 
a large collection made by Professor Forbes during the past summer (1877), 
chiefly in the streams of southern Illinois. The writer’s own collections in 
Illinois and adjacent states have also been drawn upon, as well as those 
contained in the United States National Museum. The various scattered 
notices of Illinois fishes have also been brought together as far as possible, 
thus giving all that is at present known of the distribution of the species 
within the limits of the state. 
Reference has been made throughout this paper to the second edition 
of the author’s Manualj* of Vertebrates, (quoted as “M. V.,”) in which 
nearly all the species here mentioned are described. No synonomy is given 
except that of Mr. Nelson’s list, above mentioned, of which paper the pres- 
ent may be considered as, in a sense, a revised edition. 
A few species either new to science or new to our fauna and therefore 
not noticed in the Manual, are here described in full. 
In all cases where I have found exact record of localities of species, 
these have been inserted. Species not yet taken in Illinois, but included in 
the catalogue on the strength of our general knowledge of their range, are 
indicated by a star (*).
