Fishes of the IVestern North Atlantic 551 



taken in "full salt water"^ in midchannel at the mouth of the Sissibo River, St. Mary 

 Bay, Nova Scotia, in 1919(5: 59). These specimens, no longer in existence, were doubt- 

 fully identified as quadrilatcralis, the Round Whitefish, which is commonly placed in 

 the genus Prosopiuni\ but doubtless they were clupeaformis, for R. A. McKenzie has 

 written that all of the whitefishes from that general part of the Province received at 

 the St. Andrews Laboratory of late years have been clupeaformis.* W. B. Scott has also 

 reported that an additional clupeaformis was caught off a wharf at Wedgeport, Nova 

 Scotia, in July 1954, and that others were taken or seen there during the ensuing 

 month by W. L. Klawe.* But there seems to be no reason to suppose that any 

 regular sea-run populations of whitefish occur anywhere on the Atlantic coast of 

 America or among the Arctic islands to the north. 



In Hudson Bay, however, in the vicinity of Churchill on the west coast and in 

 James Bay northward to Great Whale River in the east, both Lake Whitefish (Coregonus) 

 and Round Whitefish (Prosopium) as well as one of the Ciscoes {Leucichthys artedi, sub- 

 species not recorded) appear to run down regularly into salt water (j: 12).

4. Specimens of clupeaformis that were taken in fresh water in the headwaters of the LaHave River, Canada, were in- 

 advertently included among a list of marine records (McKenzie, 6: 43).
