Errors in identification of Blacknose Dace date back to 20 July 1941 when C. F. Allen mis-identified three Northern Redbelly Dace, P. eos, from Grand Lake, Halifax County, as Striped Dace, Rhinichthys atronasus, the common and scientific names in use at that time for Blacknose Dace (Scott and Crossman 1973). This record was repeated by Davis (1981). There are a number of other incorrect records, also from localities outside the range for Blacknose Dace in Nova Scotia. We suspect Blacknose Shiner, Notropis heterolepis, have been incorrectly identi- fied as Blacknose Dace in a report on Lake Egmont (Parker 1994). Another such record is Anonymous (1998) in which Blacknose Dace was reported from 35 localities across the northern mainland; 11 are in north-eastern Nova Scotia well outside its con- firmed range. Between 1972 and 2000, J. G. investi- gated streams between West River Pictou, Pictou County; and St. Marys River, Guysborough County, for freshwater fishes and did not find Blacknose Dace at any of the sampled sites. Juvenile Creek Chub were observed in the St. Marys River that have a prominent black lateral band which extends onto the head, possibly
