noted at Dealy Island, June 16, 1853 (M'Dougall), Fort Conger, lati- 

 tude 81° 40', June 18 and 20, 1883 (Greeley), and Thank God Harbor, 

 about the same latitude, June 14, 1872 (Davis). The species cer- 

 tainly did not breed that season at Fort Conger, and probably did 

 not at Thank God Harbor. Its regular breeding range does not seem
