This preliminary checklist has been prepared for the use of students and biologists working in the Chesapeake Bay area. The list is conservative and probably omits a number of species, especially small snails and parasitic groups like the pyrams. All species listed, with one or two exceptions, have been collected as live specimens by the author, and collections of each have been deposited in the U. S. National Museum. Species given in the literature but not yet confirmed by specimens in the National Museum have been purposely omitted.

The checklist includes all species collected in the brackish waters of Chesapeake Bay except certain fresh-water groups, e.g. the hydrobiids, which invade salty waters a short distance. The ocean shore of Virginia, both on Eastern Shore and the mainland, has been excluded.
