sula and North Georgian Islands, as well as in Baffin Bay.

Franklin, lat. 65° 15’ N. (Richardson.) A specimen of the melan- 
istic form taken at Fort Churchill, Hudson Bay, 1845. (Dr.

Behring Sea, but is most numerous along the low marshy coast 
of Norton Sound and thence south to the Kuskoquim River.

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

BREEDING Notes.—I have a clutch of two eggs that were 
taken at Skonntzaz, Greenland, on June 11th, 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. (J/Ve/son.) 
38. Long-tailed Jaeger. Buffon’s Skua. 
Stercovarius longicaudus VIEILL., 1810. 
Said not to breed farther south than lat. 70° N., in Greenland. 
(Arct. Man.) A very few of these birds visited the upper waters
