Distribution In North America, the Eastern Sand Darter has been found in the Ohio River basin in Ohio, Indiana, Illinois, Kentucky, W. Virginia, and Pennsylvania. It has been recorded from the Lake Huron, Lake St. Clair and Lake Erie drainages in Michigan, Ohio, New York, and Ontario. It has not been recorded in the Lake Ontario drainage, but occurs farther east in Saint- Laurent (St. Lawrence River) and Lac Champlain drainages of Quebec, Vermont, and New York (see inset. Figure 2). Recent reductions in distribution have been documented in Kentucky (Kuehne and Barbour 1983), Illinois (Smith 1971), Ohio (Trautman 1981), Michigan (Smith et al. 1981), and Pennsylvania (Cooper 1983). Since 1970, Ammocrypta pellucida has been recorded at new localities in New York (Smith 1985), Ontario, and Quebec. In Ontario, Ammocrypta pellucida was collected prior to 1970 from the Ausable River, the Sydenham River (Kent, Lambton, and Middlesex counties), and the Thames River, Catfish Creek, Big Otter Creek, and Big Creek. It was first collected in the Canadian waters of Lake Erie in 1953 at Pelee Island, and in both eastern and western basins of Lake Erie in 1957. Since 1970, specimens have been collected at new locations in Lake Erie at Rondeau Bay and Long Point Bay, Lake St. Clair, and in the Grand River [see Figure 2 (Appendices of all records are on file and available on request from COSEWIC, Canadian Wildlife Service, Ottawa, Ontario KIA 0H3)]. In Quebec, Ammocrypta pellucida was collected prior to 1970 in Lac des Deux-Montagnes near Mon
