60 CRUISE OF STEAMER CORWIN IN THE ARCTIC OCEAN. 
supposed to result from its passage westward along the northern shore of America from Greenland 
and its adjoining habitat, evidently entering Northern Alaska and perhaps Northeastern Asia 
from Europe by way of the Northwest Passage. 
SYLVIIDZ. OLD-WORLD WARBLERS. 
SYLVAI EVERSMANNI, 
(8.) EVERSMANN’S WARBLER. 
Flocks of this small bird came during the middle of June and settled on the Vega at Tapkan, 
her winter quarters, northwest of the Straits. This was before the ground was free from snow, 
and the birds appeared to be much exhausted. 
PHYLLOSCOPUS BOREALIS (Blas.) Dresser. 
(9.) Kaennicot?T’s WARBLER. 
The first American specimen of this Siberian Warbler was taken by the naturalist of the 
Western Union Telegraph Expedition at Saint Michael’s, Norton Sound, in 1866. Since then no 
others have been secured until the three specimens I had the good fortune to obtain at the same 
locality during my residence at that place. Its recurrence appears to be very irregular, as it was 
found only in two seasons out of four, during which I kept a sharp lookout and had native 
collectors searching for them, but obtained and saw only the examples mentioned. It has never 
been taken on the Siberian shore of the region covered ‘by this paper, but further towards 
Middle Siberia it is known to be common, extending its summer range to the vicinity of the Arctic 
Circle, passing south through Eastern and Central Asia in its autumnal migration. In the region 
of Lake Baikal it is a common migrant, as well as further east in Siberia. How gen eral its range in 
Northeastern Siberia is can only be determined when the numerous ornithological problems of 
that country are solved by the work of some ornithologist. 
PARIDA. TITMICE. 
PARUS ATRICAPILLUS SEPTENTRIONALIS (Harris.) Allen. 
(10.) THE LoNG-TAILED CHICKADEE. 
An irregular visitor to the Alaskan shore of Bering Sea, mainly about Norton and Kotzebue 
Sounds, where it is not a rare bird in the fall and at times also in the spring. But it is never 
resident here, owing to the lack of suitable shelter. 
PARUS CINCTUS GRISESCENS, Sharp & Dresser. 
(11.) THE SIBERIAN CHICKADEE. 
Though to be accounted a Siberian species by right of general distribution and priority of 
discovery, yet this little Chickadee makes its home among the spruce and paper-birch forests of 
Northern Alaska, and like the preceding makes occasional excursions to the adjoining coasts and 
comes familiarly about the houses, where it enlivenes the gloomy opening of the long cheerless 
winter or breaks into the monotony of the silent frosty days later in the season. 
Although Mr. Ridgway identified the original American specimens of this bird as typical 
Parus cinctus, a more careful examination of a much larger series made by myself shows that it is 
really referable to the much grayer and somewhat larger Eastern Siberian form, described in 
“ Dresser’s Birds of Europe,” and to which all American specimens should be referred. 
PARUS HUDSONICUS Forst, 
(12.) Tur HupsonrIAN CHICKADEE. 
This bird is the third and last of a band of active, cheerful wood-sprites, whose busy notes 
and amusing motions while playing at gymnastics, as they rove in merry troops through the wood-
