Local material already in the museum collections has been 
freely drawn upon and is listed fully under each species, with its 
museum number and the name of the collector. A considerable 
part of this material consists of polished "Unios", purchased from 
Mrs, E. C. Wiswall, and bearing, almost without exception, the 
very indefinite locality, "Wisconsin." Despite the small value 
of such data for purposes like the present, the species will be 
found admitted to the list on their own recognizance, as all are 
likely to occur within the borders of the state. Additional 
records have been derived from an exchange list of Kenosha 
shells submitted by Mrs. Wiswall during her residence there, and 
from lists of further accessions, later received through Mr. Brown, 
including that of the Bunde & Upmeyer collection of Mississippi 
river bivalves from Crawford County. All these are accompanied 
in the lists by the name of their sponsor. 
Lastly, all citations of Wisconsin localities in the authorities 
consulted have been incorporated, with page reference. This has 
been done in spite of some repetition, and all the available litera- 
ture (up to 1902) has been searched in order to have the record 
historically complete. Many important papers have no doubt
