higher elevation deeper in the wood, and even in a more exposed 
position; but a few days after the nest 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.)

(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.)

This bird is of doubtful occurrence in Alaska and is admitted on 
the capture of a single specimen in “Northwest America” by Capt. 
Kellett and Lieut. Wood; I obtained a fine male adult on June 23rd, 
1881, in Plover bay, on the east coast of Siberia. (Nelson.) At 
Attu 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. (Twrner.) 
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 returnep
