 quotes svarbag, Briinn. 



European and American coasts and islands of the North Atlantic, to or be-

 " Its most favorite breeding-places south of the Straits of Belle Isle, are the 

 Funk Islands, off the coast of Newfoundland, Bird Rock, near the Magdalen 

 Islands, in the Gulf of St. Lawrence, and a number of small islands, generally 

 called JIurre Rocks, between Meccatina and the Esquimaux Islands, on the 

 north shore of the Gulf," (Bryant). In winter to the extreme southern coast 

 of New England. Specimens in all American cabinets. 



Adult, summer plumage. — Head and neck all around rich dark brown, A'hich 

 changes on the back of the neck into dark slaty-brown, the color of the rest of 

 the upper parts. This hue is nearly uniform, but most of the feathers of the 

 back and rump have usually just appreciably lighter and more grayish-brown 

 tips. Secondaries narrowly, distinctly tipped with pure white. Exposed por- 

 tion of primaries dusky blackish, the shafts of the few outermost, and the 

 greater part of the inner webs of the whole, lighter (more grayish-brown), 

 tending to grayish-white towards the bases. Under wing coverts mostly white, 

 variegated with dusky along the edges of the wing, and the greater coverts 

 mostly of this latter color. Entire under parts from the throat pure white;
