224. Dendroica townsendi. Townsend's Warbler. 



Rare east of Cascades, but abundant in Washington and on Van- 

 couver Island. 



225. Seiurus noveboracensis notabilis. Grinnel's Water Thrush. 



Found breeding along interior streams. Lac La Hache and 

 Bonaparte. 



226. Geothlypis macgillivrayi. Macgillivray's Warbler. 

 Found breeding at all localities and elevations. 



227. Geothlypis trichas oocidentalis. Western Yellow-throat. 



Rare on Vancouver Island. Abundant at Lulu Island and about 

 the shores of reedy lakes in the interior of British Columbia. 



228. Icteria virens longicauda. Long-tailed Chat. 



In the bushes which line the banks of the Thompson River below 

 Ashcroft I secured two males of this species. Another was heard 

 singing on a ranch above the town. Fort Lapwai, Idaho, was here- 

 tofore the most northern record for this Chat. 



229. Sylvania pusilla. Wilson's Warbler. 

 Sylvania pusilla pileolata. Pileolated Warbler. 



The series of Wilson's Warblers taken in eastern and western 

 British Columbia, compared among themselves and with specimens 

 from the Atlantic States, are devoid of any differences which would 

 justify their separation. There is a singular uniformity in the aver- 

 age measurements of specimens from all localities and, saving two 

 specimens from Vancouver Island which show deeper yellow on the 

 forehead, their coloration is remarkably uniform. Judged by the 

 specimens examined, there is not, when we consider its transconti- 

 nental range, a more " hard and fast" species than Sylvania pusilla. 



North of the United States 8. pusilla pileolata has no better claim 

 to recognition than Dendroica aestiva morcomi.- 



230. Setophaga ruticilla. Redstart. 



Well represented all over interior British Columbia. 



231. Anthus pensilvanicus. American Pipit. 



Washington and the Province of British Columbia at large. 

 Breeding sparsely on the plateaus and mesas of the interior, up to 

 4,000 feet. 



232. Cinclus mexicanus. American Dipper. 



Associated with all dashing streams, from the mountains to the sea.
