58 PROCEEDINGS OF THE ACADEMY OF [1893. 



248. Parus rufescens. Chestnut-backed Chickadee. 



Very common on the coast and Islands but never found east of 

 the Cascades. 



249. Regulus satrapa olivaceus. Western Golden-crowned Kinglet. 



I can find no color difference between the east and west Cascade 

 Kinglets. In this respect they agree with the British Columbia 

 Winter Wrens. 



250. Regulus calendula. Ruby-crowned Kinglet. 



Numerous on the coast in spring. Breeding in the interior. The 

 nuptial song of this tiny bird is a truly marvellous production. 

 Perched in the top of a giant fir it will remain motionless for thirty 

 minutes at a stretch, singing an incessant hurly-burly loud enough 

 to be heard half a mile away. 



251. Myadestes townsendii. Townsend's Solitaire. 



I secured a Solitaire on Vancouver Island in May. They were 

 met with at high altitudes on both slopes of the Cascades, Selkirks 

 and Rockies, as far north as the 52nd parallel, increasing in abun- 

 dance eastwardly. 



252. Turdus fuscesens salicicolus. Willow Thrush. 



In all visited localities of the interior. Breeding at Lac La 

 Hache. This extends Mr. Streator's nesting record of the species 

 150 miles farther north. 



253. Turdus ustulatus. Russet-back Thrush. 



Abundant coastwise. 



254. Turdus ustulatus swainsonii. Swainson's Thrush. 



A female and young male in nesting plumage shot at Nelson 

 where they were fairly abundant. 



255. Turdus aonalaschkae. Dwarf Hermit Thrush. 



On the coast in migrations. Probably breed in the Cascades and 

 mountains of Vancouver Island. I was surprised to again meet 

 this species at Field, where I saw many and secured three birds. 

 One of these in spotted nesting plumage proves that the summer 

 habitat of the Dwarf Thrush is far more extended than formerly 

 supposed and accounts for the appearance of this form in Utah and 

 Nevada in fall migrations. 



256. Turdus aonalaschkae pallasii. Hermit Thrush. 



That pallasii and not auduboni breed in the region around Lac 

 La Hache is attested by certain skins in the collection. Neither
