PagopMla alba (Gunn.). Ivorj' Gull.

 Bay.'* This gull has also been recorded from Port Bowen and from 

 other localities to the north of Keewatin.

 giA'es a description of one killed on Melville Peninsula in Jul3\'' A 

 specimen from the Savage Islands, Hudson Bay, is recorded in the 

 British Museum Catalogue. 



Larus glaucus Brilnn. Glaucous Gull. 



Doubtless found in all parts of Hudson Ti&j. It has been recorded 

 from Melville Island, Felix Harbor, and other places in the Arctic 

 regions, and has been found breeding in James Bajr and at various 

 points on the east coast of Hudson Baj'.*^ 



Larus leucopterus Faber. Iceland Gull.

Larus marinus Linn. Great Black-backed Gull.

 lakes and larger rivers, and breeding throughout the region. It is 

 usuallj' very shj, however, as it is shot for food ).)y the natives when-

 specimen July 28, the eggs are gathered in large numbers in May and 

 packed in salt, to be eaten in the late autumn and early winter. On 

 our return trip during the latter part of August and fore part of 

 September, many birds in the dark, immature plumage, sometimes 

 almost sooty, were seen.
