78 CHECK LIST OF FISHES OP THE DOMINION. 



277. Theragra fucensis* Jordan and Gilbert. 

 Wall-eyed Pollack. 



Marine. 



British Columbia and Puget Sound southward to coast of California: probably extends 

 northward to coast of Alaska. 



278. Microgadus proximus Girard. 

 California Tomcod. 

 Marine. 



British Columbia: ranges from coast of California northward to coast of Alaska, including 

 the Aleutian Islands. 



279. Microgadus tomcod Walbaum. (Plate IX, figures 91 and 92). 

 Tomcod: Frostfish. 



Anadromous. 



Ranges from coast of Labrador, and embracing the Gulf of St. Lawrence, Gaspe Bay, and 

 Maritime Provinces, southward to the coast of Virginia. 



280. Gadus callarias Linmcus. (Plate IX, figures 93 and 94). 

 Common Codfish. 



Marine. 



Both sides of north Atlantic: ranging on the American side at leastf from coast of Labra- 

 dor, and embracing the Gulf of St. Lawrence, Gaspe Bay, Maritime Provinces, and 

 Newfoundland, southward to coast of Virginia; and on the European side "found uni- 

 versally from Iceland very nearly as far south as Gibraltar" (Yarrell, 1859). 



281. Gadus macrocephalus Tilesius. 

 Pacific Codfish. 



Marine. 



British Columbia: both coasts of northern Pacific, ranging from Bering Sea southward to 



the off-shore banks of Oregon and to Japan: said to be very abundant in the sea of 



Okhotsk. 



282. Gadus ogac Richardson. 

 Greenland Codfish. 

 Marine. 



Recorded from Labrador and Greenland. 



*"This form may intergrade with Theragra chalcogrammu , though the original types seem well separated. 

 Little is known of its range to the northward." Jordan and Evermann. 



■fO. callarias, 67. macrocephalus, and G. ogac, are very closely allied, and in assigning specific rank to each it is 

 not easy from ichthyological works to determine just where the northern range of (1. callarias is as the three forms 

 are often treated of as one and the same species. For instance, Goode says: — "The codfish is usually found in the 

 North Atlantic, in the North Pacific, and in the Polar Ocean, its range extending far beyond the Arctic Circle" — 

 thus making no discrimination of species.
