NORTH AMERICAN GULLS AND THEIR ALLIES. 11 
noted at Dealy Island, June 16, 1853 (M'Dougall), Fort Conger, lati- 
tude 81° 40', June 18 and 20, 1883 (Greeley), and Thank God Harbor, 
about the same latitude, June 14, 1872 (Davis). The species cer- 
tainly did not breed that season at Fort Conger, and probably did 
not at Thank God Harbor. Its regular breeding range does not seem 
to extend north of about latitude 75°. At Point Barrow, Alaska, 
the first arrived May 31, 1882, and May 29, 1883 (Murdoch), and 
June 1, 1898 (Stone); at Kigulik Mountains, Alaska, May 21, 1905 
(Anthony); at St. Michael, Alaska, May 7, 1851 (Adams); and at 
Bering Island, Kamchatka, May 4, 1883 (Stejneger). Some other 
spring records, probably accidental, are: Stone Harbor, N. J., May 
27, 1901 (Voelker) ; Tacoma, Wash., May 17, 1897 (Bowles); and 
Renovo, Pa., June 18, 1911 (Pierce).

Alaska, June 20, 1899 (Grinnell); mouth of the Mackenzie River,

Greenland from June 4 to July 25 (Hagerup). 
Fall migration. — Birds common near Cape Eskimo, Keewatin, 
August 4-13, 1900 (Preble), were probably in fall migration, while 
by this date they had already appeared much farther south at 
Little Gull Island, N. Y., August 6-16, 1888 (Dutcher), and at Mont- 
erey, CaL, August 1, 1892, and August 4, 1894 (Loomis). Some
