The following catalogue of Illinois mollusks is intended to record every reference to the Mollusca occurring in the state which may be found in the few published lists, and also all scattered references to the same, wherever published. The bibliography is believed to contain a majority of the publications referring to the Mollusca of the state, but it can scarcely be complete, since references probably exist which are unknown to
the author. The classification is that of Dall, Pilsbry, and Simpson.
The valid species (so considered at the present time) overhang at the margin, while those specitic names which have been used in Illinois references and which are now considered synonyms follow in parenthesis. In indicating the geographical distribution the author has deemed it best simply to quote every locality from which specimens have been recorded, adding after each locality, in parenthesis, the name of the collector or author who is authority for the same. By this means an exact census of our molluscan fauna will be secured, based on actual collections. There have been several references to species which are evidently founded on misidentifications. These are indicated in foot-notes under their respective genera. Several species are listed on the authority of correspondents, and the identifications have not been verified.
