340 ArPE>'Dix. 



maries, secondaries, and of some of the coverts, grayish-white ; 

 throat, breast, and medial portion of the belly dusky-cinereous; sides 

 under the wings and flanks, dusky ; the whole inferior surface of 

 the body is banded transversely with blackish ; the bands upon 

 the throat are broken, and not well defined, but as they approach 

 the tail they become more distinct ; lower tail-coverts with 

 strongly marked alternate transverse lines of blackish and white. 

 The tail is much longer in proportion than that of the preceding 

 species. Irides dark hazel. Legs and feet bright yellow. Length 

 about 7 inches. 



This fine bird inhabits the swiftly running streams of fresh 

 water in the vicinity of Fort Vancouver. It is a very scarce 

 species, as in all my peregrinations I have met with but two in- 

 dividuals, only one of which I was enabled to procure. 



This I observed swimming about among the rapids of the 

 stream, occasionally flying for short distances over the surface, 

 and then diving into it, and reappearing after a long interval. 

 Occasionally it would alight on the stones, and at such times 

 jerked the tail in the manner of some of the sandpipers. I did 

 not hear it utter any note. 



Hermit Warbler. 



Sylvia *occide.ntalis, (Townsend.) Journal Acad. Nat. 

 Sciences, Vol. 7, part IL, p. 190. Audubon's Birds of America, 

 Vol. IV., pi. 39.5. Male and female. 



The bill is wholly black ; the frontlet, crown, and sides of the 

 head yellow, the former rather sparingly dotted with blackish 

 near the nape, where the yellow color almost disappears, by the 

 increase in the size of the spots ; upper parts grayish, thickly 

 spotted with black, and most of the feathers tinged with olive ; 

 the rump is somewhat lighter, having few or no spots, and more 

 strongly tinged with light olive ; wings cinereous, with two bands 

 of white ; tail darker, the three lateral feathers with white on their 

 inner vanes ; throat deep black ; whole' lower parts white. Legs and 

 feet blackish, the soles yellow. Length 5 inches. Extent 7 inches. 



The female difl^ers from the male in having the yellow of the 

 crown and cheeks less bright, the dark spots upon the head are 

 larger and more numerous ; the back is of a lighter tint ; the 

 black centres of lTie feathers smaller, and the throat wants the 

 jetty black which is so conspicuous in the male.
