. The Canadian field-naturalist. 1984 NOTES 497. Figure 1. A specimen ofZ^poww^u/o^wi ROM 43022 captured by G. Moulandin Lake Pond, Point Pelee National Park, 3 June, 1983. The specimen is 155 mm TL. Note the large mouth, the three anal spines, and the round clear spots on the second dorsal fin. retained as reference specimens (ROM 43022). No other records resulted from queries sent out, in late 1983, to all fisheries agencies along the Ontario shores of Lake Erie and of the Detroit and St. Clair rivers. The only published notation of this species in Canada was a brief note (p. xv) in a section of new information added to the third printing (1979) of Freshwater Fishes of Canada (Scott and Crossman 1973). The northern limit of distribution of the species (Lee et al. 1980) is a line from central Wisconsin to Maryland. The species extends southward to the Gulf coast, from Florida to Texas, and westward from the Atlantic coast to New Mexico. Although these Lake Erie records are the first from Canada, the species does occur farther north in Wisconsin (approximately 45° N, 89° W). The nearest populations are those in Michigan tributaries of Lake Erie rather than those across the lake in Ohio. Regardless of their source, it seems more likely that the pioneers moved around the shore rather than across the lake. In that case, one would have expected them to have appeared first at Point Pelee rather than Rondeau. It is also of interest that, although no further specimens have apparently been seen at the original Rondeau location, a breeding population has been established at Point Pelee. The known captures of Warmouth have been from ecological situations typical of sunfishes. Other cen- trarchids — L. gibbosus, L. macrochirus, Pomoxis annularis, P. nigromaculatus, Micropterus sahnoides. and other "warm-water" fishes — Amia calva, let alu- ms nebulosus, Percaflavescens — were captured with this species at Rondeau Provincial Park in 1968.
