of Cumberland Gulf in June, 1871, and soon disappeared ; I 
doubt if they breed there. (Kwmelin.) Occasionally seen from 
Greenland south along the Labrador coast (Packard); Newfound- 
land (Reeks); coast of Nova Scotia (Downs); in the Bay of 
Fundy (Boardman) ; Gulf of St. Lawrence (Dionne) ; occasionally 
taken in Hudson Bay (Jy. &. Bell); south to Lapierre’s House 
on the Mackenzie River. (Ross.) Quite abundant along the Ander- 
son River and on the Barren Grounds, and also on the Arctic 
coast. (Macfarlane.) This is the most common of the Jaegers 
on the Alaskan coast ; rare on the Prybiloff Islands. They are 
abundant on the low coast of Behring Strait, but, except at 
Kotzebue Sound, they are not common beyond that point. (Vel- 
son.) Arrives earlier at St. Michael and in greater numbers than 
its congeners ; rarely seen on the eastern Aleutian Islands, but 
a few pairs are said tobreed near St. Michael. (Zarner.) This is 
the most common species of Jaeger at Point Barrow, and is rather 
abundant, but none breed. (Mzurdoch.) Once shot and several 
times seen during September, 1890 and 1891, at Sumas Lake, B.C. 
(Brooks.) 
BREEDING Notes.—The pairing occurs with a great amount 
of noisy demonstration on the part of several rivals, but once 
paired the birds keep by themselves and early in June deposit 
their eggs in a depression on the mossy top of some knoll upon a 
rising ground. (JVe/son.)
