A nest of the Alaska pileolated warbler was found by Steph- 
ens on the 7th of June near Hasselborg Lake, Admiralty Island. 
It was in the thick moss growing among the roots of an uprooted 
tree in a-creek bottom. The nest was about five feet from the 
ground and occupied a niche in the mass of moss which over- 
hung and hid it. The nest consists externally of moss, weathered 
leaves, and bark strips; internally of deer hair. The cup-shaped 
inner cavity is 46 mm. across and 30 mm. deep. The set con- 
sists of five eggs in which incubation had scarcely commenced. 
These are pure white, finely dotted, chiefly in a ring around the 
large ends, with brick red and heliotrope purple. They measure:

Anthus rubescens (Tunstall). American Pipit. 
Pipits were found early in May in small flocks, evidently in 
migration, at Windfall Harbor, Admiralty Island, where they 
frequented the beach among the melting ice cakes. A pair (Nos. 
369, 370) were taken there May 4 and 8. The male has the 
lower surface strongly tinged with cinnamon, but no more so 
than in some nuptial-plumaged males from elsewhere. 
The species evidently breeds in the Sitkan District but only 
in the Aretie Zone, above timber-line, along with the ptarmigan 
and leucostictes. A pipit was seen on the summit of a mountain, 
2300 feet altitude, near Hasselborg Lake, May 31. Another was 
noted at the same elevation on a mountain near Red Bluff Bay, 
Baranof Island, in June, and in August Stephens saw several 
on the top of a mountain at Rodman Bay, the same island. Dixon 
shot an adult male (No. 360) at Glacier Bay, July 10. 
Cinclus mexicanus unicolor Bonaparte. 
North American Dipper. 
The single skin (No. 310) brought home by the party was 
secured by Miss Alexander at Windfall Harbor, Admiralty Isl- 
and, April 22. It is fully adult, and I can appreciate no differ- 
ences in color between it and dippers from California, but in 
size it is slightly larger. The wing measures 92 mm., though 
this dimension is exceeded, according to Ridgway (Bds. N. & 
Mid. Am., Part III, 1904, p. 679), in the case of Roeky Mountain
