the black. A male killed in Davis's Straits 
early in June, had the whole head and 
neck mottled with black and white, equally 
distributed ; the plumage beneath and the 
back being black, with a few white fea- 
thers dispersed ; the lower part of the ab- 
domen grey as in the neck; the speculum 
still mottled, but with the white predomi- 
nating. This bird was killed on our first 
arrival in the Greenland seas; and it is 
presumed that the change to full summer 
plumage was proceeding very rapidly, as 
we did not afterwards see a mottled bird." 
These birds are found in great numbers 
in the North Sea, in Greenland, Iceland, 
Lapland, Spitzbergen, the Feroe Isles, &c. 
and when the winter sets in they migrate 
southward along the shores of Scotland 
and England, where some of them remain 
and breed. 
The Greenlanders eat the flesh of this 
bird, and use its skin for clothing, and the 
leg-s as a bait for their fishing lines.
