rock, Heller records pipits as seen on a mountain on Dise Isl- 
and, September 4, and as abundant on the beach in Valdez 
Narrows, September 12 to 21. Miss Alexander saw many indi- 
viduals at Thompson’s Pass, on the Eagle Government Trail, 
August 31, and secured two (nos. 1311, 1312). These specimens 
are in complete first winter plumage, and are darker and more 
cinnamomeous than winter birds of later date from California 
and the Atlantic States. This difference is possibly because the 
plumage is fresher, that is, not worn and faded. The two June 
breeding birds (from Cordova Bay) are distinetly less ashy than 
May examples from the upper Yukon, and the wings are slightly 
shorter. But the material at hand is too scanty to warrant any 
conclusions as to subspecifie separateness. 
Cinclus mexicanus unicolor Bonaparte. 
North American Dipper. 
Eight obtained (nos. 1279-1286), five of which are full- 
erown juvenals dating from June 27 to July 27. Both adults 
and young appear to me closely similar to corresponding stages 
from California, save that the latter average a trifle smaller. 
The species was found in suitable places both on the islands and 
mainland. At the head of Cordova Bay several were seen along 
streams and one taken by Heller, June 13; a partial albino was 
repeatedly seen there June 11. Three specimens were taken 
by Miss Kellogg at Northeast Bay, Hinchinbrook Island, June 
27 and 28. Miss Kelloge secured three more specimens at Han- 
ning Bay, Montague Island, July 26 and 27. Miss Alexander 
obtained one on Latouche Island July 19, and saw another near 
the mouth of Port Nell Juan, August 11. At Drier Bay, Knight 
Island, Heller saw two dippers the last of August. 
Nannus hiemalis pacificus (Baird). Western Winter Wren. 
Sparsely distributed through the region, and not common any- 
where. Thirteen examples were secured (nos. 1344-1356), from 
Montaeue Island (both Zaikof and Hanning bays), Green Island, 
Hoodoo Island, and the mainland at the head of Port Nell Juan. 
The species was seen also on Dise Island. A full-grown young
