 in the southern ; also on the west coast of Davis Strait and in the 

 Polar Sea. (Jlrct. Man) Along the Atlantic coast, in spring and 

 autumn, as far south as Grand Manan. {Herrick.) Gulf of

 Gillespie, Jr.) This bird occurs about the entire coast line of 

 Behring Sea, but is most numerous along the low marshy coast 

 of Norton Sound and thence south to the Kuskoquim River.

 at St. Michael. (Turner.) Not common at Point Barrow ;

Breeding Notes. — I have a clutch of two eggs that were 

 taken at Skonntzaz, Greenland, on June nth, 1890. (Raine.) 



Birds in the black plumage are rare in the spring, but are some- 

 times seen ; and at the Yukon mouth, on May 31st, I found a pair 

 in this plumage mated. The eggs are laid upon the mossy knolls 

 or uplands in their haunts about the 5th of June. The nest is 

 merely a depression in the moss, containing two eggs indistin- 

 guishable from the next species. (Nelson.)

Stercorarius longicaudus Vieill., 1819. 



Said not to breed farther south than lat. 70" N., in Greenland.
