EUesmere Land, Prince Eegent Inlet (Port Bowen), and presumably 

 Hudson Bay. It was stated by the late Manly Hardy to have nested 

 on an island in Penobscot Bay 50 years ago (about 1847) and a 

 bird and egg were taken. Stone refers 17 specimens from Point 

 Barrow, Alaska, to this form. In Europe breeds from Jan Mayen, 

 Iceland, Spitzbergen, Franz Josef Land, and Nova Zembla to the 

 Siberian coast (eastern limits not determined) and Bennett Islands, 

 76° 39' N. 



Winter range. — From Southern Greenland and Hudson Bay south 

 to Maine. Irregular, but at times common, from Massachusetts, 

 southward, New York (Long Island), New Jersey, and Delaware to 

 South Carolina (Anderson). Occasionally common on the Great 

 Lakes, straggling to northern Ohio (many taken 1896), Indiana 

 (December, 1896), and central Iowa (two specimens). In Europe 

 winters farther north, rarely south of Norway, Great Britain, and 

 the North Sea. 



Spring migration, — Said to arrive at Franz Josef Land as early 

 as March 9; at Prince Regent Inlet, west of Baffin Land, early in 

 June. Northern Greenland, Cape York, May 10; Saunders Island, 

 May 20; Cape Sabine, June 11. 



Fall migration. — Birds leave their nesting grounds by early Sep- 

 tember. The last seen in northeastern Greenland, latitude 74°, 

 August 1. Migration in the eastern United States usually occurs in 

 December and through the Great Lake region during November or 

 early December; Ontario, Ottawa, November 25 to December 8. 



Egg dates. — Bird Rock, Gulf of St. Lawrence: 16 records, June 

 5 to July 25 ; 8 records, June 18 to 26. Greenland : 8 records June 10 

 to July 18; 4 records July 3 to 12. Eastern Labrador: 4 records, 

 June 10, July 1, 2, and 11. 



ITRIA LOMVIA ARRA (Pallas). 



PALLAS'S KTJERE. 



HABITS. 



The western form of tJria lomvia Imown as Pallas's murre ( Uria 

 lom/via arra) is decidedly larger than the eastern or Atlantic form; 

 the bill is larger and more slender and the white of the maxillary 

 tomium is duller or more grayish. The "crowbill," as it is called 

 by the sailors, is the most important, probably the most numerous, 

 and certainly the most generally distributed of the birds of Bering 

 Sea. To the natives it is most valuable as an egg bird, for its eggs 

 are large, palatable, abundant, and easily obtained; its flesh is also 

 desirable as food. While cruising about the Aleutian and Pribilof 

 Islands, in the extensive fogs which prevail there almost constantly
