higher elevation deeper in the wood, and even in a more exposed 

 position; but a few days after the niest was completed it wholly- 

 disappeared, and I suspected that an olive-sided fly-catcher that 

 had made her nest on an overhanging branch, a few rods off, was 

 the author of that. Other nests were observed, but there was 

 nothing specially noteworthy about them. (W. L. Kells.)

One sent from the southern inspectorate of Greenland in 1849; 

 another obtained by Dr. Walker at Godhavn in August, 1857. 

 {Arct. Man.) Four individuals of this species were seen by Alexander 

 Brown and James Lyell (of the Hudson Bay Company), August 29th, 

 1883, at Hunting bay, four miles south of Fort Chimo. These 

 persons described the birds accurately and declared they were the 

 two parents and two young of the year. {Packard.)

 Kellett and Lieut. Wood ; I obtained a fine male adult on June 23rd, 

 1 881, in Plover bay, on the east coast of Siberia. (Nelson.) At 

 Attn island, Alaska, I was looking out of my window on the morning 

 of May 14th, 1881, watching the vessel which was to take me to 

 Unalaska island enter the harbour; I saw a bird just beneath the 

 window on the ground, not more than seven feet from my eyes, and 

 which I believe to be this species. I failed, however, to procure it 

 and hence there is an element of doubt in the identification. (Turner.) 

 On the morning of August 28th the Robert Kerr, on which I was a 

 passenger, was hindered from proceeding by a gale and low water 

 on the bar, and was made fast to the bank at the Aphoon mouth of 

 the Yukon. As I came on deck I saw half a dozen white wagtails 

 fly about the vessel and settle in the grass close by. While I retumep
