90 Evermann and Goldshorough — Freshwater Fishes of Canada. 



collection made by Mr. Woolnian in 1894 is referred to in, the 

 list as (Woolman, coll., 1894) that l)y Dr. Evermann as (Ever- 

 mann, coll., 1898) and those l)y Mr. Preble as (Preble, coll., 

 1900) and (Preble, coll., 1903-4). Mr. Preble collected in 1900 

 along tlie shores and in the barren lands to the west and north- 

 west of Hudson Bay. In this region he obtained 9 species, 

 8 of which are freshwater species. In 1903-4 he collected in 

 the Mackenzie River basin as far north as Fort McPherson, 

 about 100 miles from its mouth. In this region he got 8 species, 

 all of which are freshwater species. 



In the following list we give, under each species, all the 

 Canadian localities from which it has been recorded, together 

 with references to the publications in which such records were 

 made. These references can be fully understood by an exami- 

 nation of the Bil)liography (pp. 114-119). 



From this list it is seen that the freshwater fish-fauna of 

 Canada as now understood consists of 145 species representing 

 25 families and 67 genera. 



The most important families, or those represented by the 

 greatest number of species, are the Cyprinidie with 33 species, 

 the Salmonidae with 28, Catostomidse 13, Cottidse 12 and 

 Percidee 12. 



The species of greatest commercial importance are, of course, 

 the salmon, whitefish and lake trout; the ones of greatest in- 

 terest to the angler are the common speckled trout, the 

 ouananiche and tlu' Atlantic salmon. 



Vernacular names are given in most cases; those in quotation 

 marks are those commonly in use in Canada. 



The territory covered by this paper is all of Canada or British 

 North America, that is, all of North America north of the 

 United States except Alaska.
