Mollusc collections held by natural history museums in the Great Lakes region were the primary sources of information, accounting for over two-thirds of the data acquired. The only records available in comput- erized format were those of the Ohio State University Museum of Zoology (OSUMZ). Records from the Canadian Museum of Nature (CMN) were computer- ized at our request, and included all uncatalogued material from the study area. Data from the Rochester Museum and Science Center (RMSC) were available in hard copy. Data from the Royal Ontario Museum.
