had just arrived from the south iu the spring. The fact of the return north of this species in 

 hirge flocks is worthy of notice. — S.

Sp. Ch. — Held above and on the sides, with chin, back, wings, and tail, black. A broad median stripe on the crown, a 

 stripe behind the eye, a well-marked collar on the hind neck all round, edges of interscapular feathers, rump, and under parts 

 generally, pale brownish orange, almost light cinnamon. Middle of belly, axillaries, and'under wing coverts, yellow. Belly 

 just anterior to the anus, under tail coverts, a large blotch at the end of the inner webs of first and second tail feathers, a band 

 across the middle and greater wing coverts, some spots on the ends of the tertiaries, the basal portiuns of all the quills, and the 

 outer three primaries near the tips, white. 



The bird is sparingly found in tlie vicinity of Fort SteiUicoora, at which place I obtained 

 two specimen.?. The person who killed these informed me that the song of the species is much 

 like the continued lay of the robin, (T. migratorius, J but stronger and clearer. 



No. 393, male, in immature plumage, killed at Fort Steilacoom, May 19, 1856. Length, 8; 

 extent, 11.87. Another, No. 450, killed in June, same plumage, hut female. Both these speci- 

 mens were unfortunately lost among a batch of 110 birds sent by me from Fort Steilacoom, 

 Puget Sound, in 1856, which have never since been heard of — S.

Sp. Ch — Upper surface generally, with the head and neck all round to the upper part of the breast, deep black; the rest of 

 lower parts pure white, except the sides of the body and under tail coverts, which are light chestnut brown; the latter rather 

 paler. The outer webs of scapulars (usually edged narrowly witli black) and of the superincumbent feathers of the back, with 

 a rounded white spot at the end of tlie outer webs of the greater and middle coverts; the outer edges of the innermost tertials 

 white; no white at the base of tlie primaries. Outer web of the first tail feather black, occasionally white on the extreme edge; 

 the outer three with a white tip to the inner web. Length, 8.50; extent, 10.50; win, 4.40; tail, 4. Female with the black 

 replaced by brownish. Iris red; bill black and brown; feet brown Iris of female olive brown. 



Hab. — Coast of Oregon and Washington Territory. 



The Oregon chewink is another representative species, having so closely the manner and 

 appearance of the Atlantic species that a common observer might consider it no more than a 

 local variety. But it differs much in song, having none of the plaintive call from which the 

 other takes its name, its cry when disturbed being a kind of "mew," from which it has derived 

 the name of "cat-bird" in the country. Its song in spring, as it sits on a low bush enjoying 

 the sunshine, is like the final trill of the red-wing, or the lisping, faint notes of the cow-bird. 

 It is a constant resident in the Territory, but does not frequent the edge of the coast, except 

 iu winter. I also found it abundant about thirty miles south of San Francisco in autumn, and 

 it is probably common to the whole region west of the Rocky mountains. — C.
