Many adults collected from the Mira River are characteristically large, robust and have a different external appearance from other Lake Whitefish in Nova Scotia (John Gilhen; Nova Scotia Museum of Natural History, Halifax, Nova Scotia; personal communication). For a detailed description of the Lake Whitefish in Canada, refer to Scott and Crossman (1973). Overall coloration of the Lake Whitefish in Canada is sil- very, grey or greenish with darker grey, greenish, light brown or dark brown back, becoming silvery on the sides and silvery or white below. The mouth is predominantly inferior and overhung by the snout, usually with weak teeth on the lingual plate and there are also teeth on the dentary in young fish but these are absent in adult specimens. Nuptial tuber- cles are present in both sexes, although they are fewer on females and more developed on males. Average length of adults in Canada is 38 cm total length but species can attain up to 73 cm in length. Considerable confusion over Lake Whitefish and Atlantic Whitefish, Coregonus huntsmani, has led to previous mis-identifications of the two species in Nova Scotia. Mouth shape, lateral line scales and presence or absence of teeth in adults are often good distinguishing characteristics (Edge 1987; Scott and Crossman 1973). Atlantic Whitefish differ from Lake Whitefish in generally having more lateral line scales (91 to 100), mouth usua
