86 CRUISE OF STEAMER CORWIN IN THE ARCTIC OCEAN, 
maritima in Bering Sea and the adjoining regions refer to the present bird, with an oceasional 
reference to the following species when speaking of the Seal Islands. This species, cowes?, winters 
on the Aleutian Islands as well as along the shores of the mainland in the Sitkan region and 
south. 
ARQUATELLA PTILOCNEMIS (Coues) Ridgw. 
(94.) THE PRIBYLOV SAND PIPER. 
This curious Snipe is limited in summer to the Fur Seal Islands, and thence extends north 
to Saint Matthew’s and to Saint Lawrence Islands, the first and only record of its occurrence on 
the latter island being a pair observed by us on the southern shore June 24, 1881, when we landed 
from the Corwin during a gale. The male was seen keeping close to the native huts, and was 
very unsuspicious, allowing us to approach within a few paces; he kept rising on vibrating 
wings in the face of the fierce wind blowing over the summit of the hill on which we found him, 
and uttering a sharp, metallic, trilling note, much louder and harder than the somewhat similar 
note of Tringa semipalmata. : 
Thus far, although this bird is known to be a migrant, leaving its summer home on the 
islands mentioned at the approach of winter, its habitat during the cold season is unknown. 
Whether it is confined to the southern shore of the Aleutian chain or passes to. some portion of 
the American or Asiatic coast yet remains to be ascertained. 
ACTODROMAS ACUMINATA (Horsf.) Ridgw. 
(95.) THE SHARP TAILED SAND PIPER. 
The first knowledge of this bird’s occurrence on the coast of America was obtained by me at 
Saint Michael’s, where it is an abundant species every autumn, coming during August and 
remaining until the sharp frosts of the approaching winter cause it to hasten away. Following 
my capture of the species comes its capture on the coast of Kotzebue Sound, at Hotham Inlet, the 
Ist of September, 1880, by Captain Hooper, on the Corwin, during his first cruise in the Arctic ; 
and on the 9th of September the same season Dr. Bean, on the Coast Survey schooner Yukon, 
secured a second specimen at Port Clarence, Bering Strait, and this concludes our present 
knowledge of the distribution of the species on the American coast. During the summer of 1881, 
on the 1st of August, we landed from the Corwin on the northeast coast of Siberia, in the vicinity 
of Cape Waukarem, and found these birds numerous, feeding on the flats which were closely 
bordering the shores of the Arctie Ocean and sparingly grown up with fine grass. From the 
actions of the birds at this time it was evident that they had nested in the vicinity, and this region 
is probably the true summer home of this handsome species. During. the migration it has been 
taken in Japan and along the east coast of Asia, and is known to winter in Australia and Southern 
India. 
ACTODROMAS MACULATA (Vieill.) Coues. 
(96.) Tim PECTORAL SAND PIPER. 
On the American coast of Bering Sea, as also at Kotzebue Sound, this bird is a common if 
not abundant summer resident. It is perhaps most numerous about the Yukon mouth, where it 
was preparing to breed in considerable numbers early in June, 1879. It is unknown from any of 
the Bering Sea islands, but on the north coast of Siberia, during the sammer of 1881, we found 
them numerous in company with the Sharp Tailed Sand Piper. At several points where we 
landed it was found wherever grassy tlats occur affording it proper feeding grounds. In a recent 
letter to the New York Herald, received from Mr, R. L. Newcomb, the Naturalist of the Jeannette, 
we learn that on the 18th of August, 1880, while their vessel was frozen in the ice to the northwest 
of Wrangel Island, a pair of these birds came on board. This extends their known range north to 
about 76° of latitude, and renders it probable that they breed on the islands of the Arctic Ocean 
in this region.
