Adult male (Vancouver Island, May 17; A. Forrer). General 

 colour above similar to T. aedon, but lighter and greyer brown, 

 much less rufous on the rump aud upper tail-coverts, and the tail 

 more ashy brown in shade ; below also slightly paler ; bars on 

 back and scapulars a little more distinct ; " iris brown " {A. Forrer). 

 Total length 4'2 inches, culmen 0-6, wing 2*05, tail 1-S, tarsus 

 0-05. 



Young (Vancouver Island, June 26 ; A. Forrer). Differs from 

 the adult in being much darker everywhere, and distinguished at a 

 glance from the old birds by its uniform rufous under tail-coverts ; 

 the head uniform dusky brown, the whole back clearer umber- 

 brown with scarcely any dusky bars, the upper tail-coverts uniform 

 rufous-brown ; tail-feathers very dark brown, crossed with bars of 

 blackish chequered markings on the wings, much more distinct than 

 in the adult, especially on the bastard wing ; under surface of body 

 dull whitish, the flanks browner, the thighs darker brown ; the fore 

 neck and breast fulvous brown, vrith dusky edgings to the feathers, 

 producing a mottled appearance ; " iris brown." (A. Forrer.)

Obs. It is most difficult to separate this race from the true Tror/lo- 

 dytes domtsticns, and were plumage the only character I do not think 

 that they could be kept distinct. The Western Wrens are certainly 

 greyer and generally paler than the Eastern ones ; but the specimens 

 from Manitoba are so thoroughly intermediate, that on colour alone 

 I should not hesitate to unite them. On the other hand the differ-
