Uria troile (Linn.) Lath. 1790.

 berlaifi) and on the coast of Nova Scotia. {Downs?) Very common 

 and breeding on the islands off the north coa'st of Newfoundland 

 and Labrador. {Reeks.) Common on the eastern and southern 

 coasts of Labrador, not observed in Hudson strait. {Packard.) 

 A few breed in Greenland. {Arct. Man.) Found breeding in only 

 two localities in the Gulf of St. Lawrence — at Bird rocks and

Uria troile californica (Bryant) Ridgw. 1884.
