84 NORTH; AMERICAN SHOREBIRDS. 
November or December. ,, The species is ‘not ‘late in deserting the far 
North, as evidenced by the following dates of the last ones seen: 
Thank God Harbor, Greenland, September 11, 1871 (Bessels); 
Possession Bay,. Franklin, September 1, 1818. (Sabine); Wellington 
Channel, August 28, 1852 (McCormick).,, At Cumberland Sound a few 
remained in 1877 until November (Kumlien). , 
Aleutian Sandpiper. ‘ Arquateila maritima couesi Ridgw. 
The western coast of Alaska and the: Aleutian Islands seem to be 
the principal home of the Aleutian:sandpiper. It breeds throughout 
the whole of the Aleutian Chain, ‘east to the Shumagin Islands (Dall) ; 
and also to the westward on the Commander Islands of Asia (Stej- 
neger). It winters on the Aleutians and: south along the mainland 
of Alaska to Sitka (Bischoff). A few. of;the breeding birds of the 
Commander Islands'remain throughout the winter, but most of them 
go south as far as the Kurile Islands. (Sharpe). 
Early in August, when the young are strong of wing, great flocks 
move north and: appear on the west coast. of the mainland .of Alaska, 
at least as far north.as Kotzebue Sound (Nelson);, they occur also 
inland to Nulato (Dall), and on the Asiatic side at least to Plover Bay 
(Dall). This northward migration takes. them also to the Pribilof 
Islands (Seale). They remain in this northern part of the range until 
driven south by the gathering ice; the last leave Norton Sound about 
the. middle of October (Nelson)., The earliest records of eggs taken 
on Bering Island are about the middle of May : aaa and on 
Unalaska Island the first week. in June (Reed). 
Pribilof Sandpiper. Arquatella maritima’ ptiloenemis (Coues). 
The name Pribilof sandpiper indicates the principal breeding place, 
but in addition, thé species has been found breeding on the islands 
of St. Lawrence (Nelson), St. Matthew (Elliott), and Hall (Grinnell). 
It has been taken from July 17 to August 29 on the shores of Norton 
Sound (McGregor), but: there is nothing to indicate that it breeds in 
the vicinity, and its occurrence there is probably due to a northward 
migration after the breeding season. The main winter home has not 
yet been ascertained, and the only winter records to date are those 
of a few seen in December and January at Portage Bay, near the base 
of the Alaska Peninsula (Hartlaub). In spring migration the Pribilof 
sandpiper has been taken April 1-14 at Nushagak; Alaska (Palmer), 
and in fall migration August 5-14 near Unalaska Island (McGregor). 
Eggs have been found on the ‘Pribilof Islands from eae 19 to July 6 
(Prentiss). 
- Sharp-tailed ‘Sandpiper. ‘Pisobia aurita (Latham). 
The breeding range of the sharp-tailed sandpiper is not well known. 
The bird occurs in summer on the north shore of Siberia at Cape 
Waukarem (Nelson) and the Chuckchi Peninsula’ pealnn), and this
