56 PROCEEDINGS OF THE ACADEMY OF [1893. 



233. Galeoscoptes carolinensis. Cat Bird. 



Not abundant anywhere and very local in its distribution. It 

 does not appear to get farther north than Clinton. The brownish 

 cast of upper parts, especially on the crown, rarely seen in eastern 

 skins, is very marked in some British Columbia examples and is 

 present in nearly all of them. Western birds average darker 

 beneath than specimens from the Atlantic coast. Measurements of 

 thirteen specimens (including the Streator series) from British Col- 

 umbia, give the following averages as compared with those of a 

 series of ten from the eastern United States. 



Wing. Tail. Exposed Culmen. Tarsus. 



British Columbia 2"58 3"78 -62 110 



Atlantic States 3'54 375 -63 1-12 



Both of these differences and those of coloration are too slight 

 and variable to warrant any subdivision of the species. 



■234. Salpinctes obsoletus. Kock Wren. 



Found about Ashcroft and northward to Cache Creek ; also at 

 Kamloops where one was nesting in a " section house," ten feet from 

 the railroad tracks. Five specimens from Ashcroft do not materially 

 differ from Arizona and Utah skins. 



235. Tb.ryotb.orus bewickii spilurus. Vigor's Wren. 



Abundant in the west Cascade region of Washington .and Brit- 

 ish Columbia. It is doubtful whether this species ever crosses the 

 coast mountains to the interior, it being essentially a lover of lower 

 levels. 



236. Troglodytes aedon parkmanii. Parkuian's Wren. 



I never found Parkman's Wren above the 2,000-foot limit. It is 

 not as abundaut or evenly distributed in the interior as coastwise. 



237. Troglodytes hiemalis pacificus. Western Winter Wren. 

 Abounding on the coast. Two moulting birds from the Selkirk 



Mountains near Nelson are even darker than skins from Puget 

 Sound. I did not find any Winter Wrens in the arid interior of 

 British Columbia west of the Gold Range, nor at Lac La Hache. 

 The reappearance in the Selkirks of typical pacificus and its absence 

 again from the Rockies at Field tallies perfectly with the alterna- 

 ting climatic conditions already pointed out as occurring across this 

 vast area. Dr. Merriam calls the Winter Wren found by him in 

 the Saw Tooth Mountains, Idaho, hiemalis.
