76 NOETH AMERICAN FAUNA. [No. 22, 



King- recorded the 'great northern diver' from the mouth of 

 Back River," and Murray' received a specimen from Severn House.* 

 The catalogue of birds in the U. S. National Museum collection con- 

 tains the record of a specimen collected at Moose Factory in 1881 by 

 Walton Haydon. 



Gavia adamsi (Gray). Yellow-billed Loon. 



Under the name Colynibus (/lacialis, James Clark Ross records three 

 loons, which from his description were undoubtedly of this species, 

 obtained about Boothia during (John) Ross's second voyage.'' In 

 speaking of a loon given him by James Clark Ross, which had been 

 procured in a very high latitude, and which had a yellow bill, Audubon 

 probably refers to one of these specimens.*^ 



This record extends the previously recognized range of the species 

 considerably to the eastward. 



Gavia arctica (Linn.). Black-throated Loon. 



Swainson and Richardson speak of this species as common on Hudson 

 Ba^Y," and Murray recorded it from Severn House.-'' Clarke recorded 

 an adult in summer plumage from Fort Churchill.^ Some of these 

 records may refer to jMic'ifica. 



Gavia paciflca (Lawr.). Pacific Loon. 



First seen on Hudson Ba^^ about 26 miles north of York Factory 

 July 17, and rather common northward. A fine adult male was 

 secured at Fort Churchill July 25. On the Barren Grounds below 

 Cape Eskimo, August 4 to 13, the species was abundant on the 

 shallow ponds on the tundra, where the young are raised. The old 

 birds were often seen flying to and from the Bay, where most of their 

 food seemed to be secured. The howl of a wolf, or any unusual sound, 

 was generally followed by a chorus of their wild, weird calls, lasting 

 for several minutes. The species was last seen by us below Cape 

 Churchill August 24.

6Edin. New Phil. Journ. (new ser. ), IX, p. 231, 1859. Severn House does not 

 appear on most maps. Thompson, who has had access to the maps and records of the 

 Hudson's Bay Company in London, locates it "on Severn Lake, at 54° 5' north lati- 

 tude and 92° 30' west longitude." (Proc. U. S. Nat. Mus., XIII, p. 468, 1890). In 

 Stieler's Hand Atlas it is located at the same place. If this information is correct (as 

 it probably is) Severn House should not be confounded with Fort Severn, the post at 

 the mouth of Severn River, though it is barely possible that Murray's records refer 

 to Fort Severn.
