which is probably the most northern point from which it has yet 

 been recorded. {Nelson.) Osgood took a male at Skagway, May 

 31st. 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 ist, 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.)

Dendroica occidentalis (Towns.) Baird. 1858.

 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: " i6th 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 tail 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
