which is probably the most northern point from which it has yet 
been recorded. (Nelson.) Osgood took a male at Skagway, May 
3ist. It was tolerably common at Glacier in the dense woods of 
spruce and fir, and unquestionably nesting. Altogether we noted 
about twenty individuals during our stay. Osgood took an adult 
at the southern end of Lake Marsh, north of lat. 60°, in the Yukon 
district, July 1st, and I an adult female and a young female on the 
west shore of Lake Lebarge, July 14th. This is a new species to 
the Yukon valley. (Bishop.) Two specimens taken respectively 
in Kenai mountains, Alaska, August 14th, and at Sheep creek, 
August 17th, considerably extend the range of this species to the 
westward. (Figgins.) One taken at Seldovia and one at Sheep 
creek, Alaska. (Anderson.) 
669. Hermit Warbler. 
Dendroica occidentalis (TOWNS.) BAIRD. 1858. 
A summer resident, chiefly west of the coast range in British 
Columbia. (Fannin.) We have no other record of this species, 
and yet we have looked for it every season.

of which the nest and eggs are unknown; and prior to the past 
spring (1900) the appearance of this bird in Canada has not been 
recorded, as far as I have been able to ascertain. My notes are as 
follows: ‘(16th May, 1900, 5.30 a.m., morning dull; east wind, 
warblers, etc., plentiful. After a while I was attracted to the 
centre of a cluster of tall willow trees by notes—strong, clear and 
with quite a musical ring—and as the song, short but remarkably 
pretty, was quite new to me I approached carefully under cover 
of a tree trunk and found myself within a few feet of my new ac- 
quaintance, for such it proved to be. While watching the bird 
with my field glass I noticed a tendency to jerk its tail slightly, 
and not like the ostentatious jerk of a waterthrush, but more
