264 NORTH AMERICAN FAUNA. [no. 27. 



Island August 4, 1894.° Another, taken by him at Fort Rae, Sep- 

 tember 30, 1893, but not recorded, has been examined. Hubert Dar- 

 rell informs" me that he observed large gulls with wings entirely white 

 near the base of Kent Peninsula, June, 1902. Ross's notes on L. 

 glaucescens, which he records as occurring on Great Slave Lake, and 

 as having been procured at Fort Simpson,'' probably refer to the 

 present species. Seale states that glaucous gulls were abundant all 

 along the Arctic coast east to Mackenzie Bay in the late summer of 

 1890/' Reed records a set of 3 eggs, taken on Herschel Island July 1, 

 1900, by I. O. Stringer/ 



Larus leucopterus Faber. Iceland Gull. 



J. C. Ross states that this gull breeds at Felix Harbor, Boothia/ 

 Baird, Brewer, and Ridgway state that it has been obtained at Mel- 

 ville Island/ and that " MacFarlane procured several sets of the eggs 

 of this species on the Arctic coast in July, 1803, and again in July, 

 1865." g Reed records eggs taken at Mackenzie Bay, Arctic America, 

 June 18, 1899.'' Three eggs, taken by Collinson at Cambridge Bay, 

 Victoria Land, are in the British Museum.' These are the principal 

 records regarding the occurrence of the bird within the region, and 

 the more westerly of these seem open to question. 



Larus schistisagus Stejn. Slaty-backed Gull. 



An adult male taken at Franklin Bay, Mackenzie, June 9, 1901, 

 was identified by Dr. A. K. Fisher, of the Biological Survey, in 

 1902. This appears to be the only record for the region. 



Larus argentatus Pontoppidan. Herring Gull. 



The widely distributed herring gull is abundant throughout the 

 region now under review. In 1901 a few were seen on Athabaska 

 River below the mouth of La Biche River, May 7. The species was 

 common on the lower river between the mouth of the Clearwater 

 and Athabaska Lake, May 15 and 16, and on Athabaska Lake in 

 the vicinity of Fort Chipewyan, May 18 to 31, and was noted near 

 the outlet, June 3. Several individuals were seen at Fort Smith, 

 Mackenzie, June 27. It was common on Great Slave Lake about 

 Fort Resolution, and between there and Fort Rae, during the month
