SP. CH. Head all round, fore part of the breast, and streaks on the side of the body, black ; rest of under parts, a stripe 

 on the side of the head, beginning acutely just above the middle of the eye, and another parallel to it, beginning at the base 

 of the under jaw (the stripes of opposite sides confluent on the chin) and running further back, white. A yellow spot in front 

 of the eye. Eest of upper parts bluish gray. The interscapular region and upper tail coverts streaked with black. Wing 

 coverts black, with two narrow white bands ; quills and tail feathers brown, the two outer of the latter white, with the shafts 

 and a terminal streak brown ; the third brown, with a terminal narrow white streak. Bill black ; feet brown ; iris brown. 

 Length, 5.25 to 6.38; extent, 7.75; wing, 2.30; tail, 2.10. 



Hab. Pacific coast of United States ; Fort Thorn, New Mexico. 



Moderately abundant near Fort Steilacoom. Generally found on oak trees Habits much 

 like those of the D. Audubonii. It generally arrives from the south about the first week in 

 April. S. 



I only saw one pair of the dusky warbler at Puget Sound, which seemed to have a nest, 

 though I sought for it in vain. Townsend found it &quot; abundant in the forests of the Columbia.&quot; 

 (Nutt.) Its song is faint and unvaried. C. -

 feathers mostly edged with white. Crown, rump, and sides of breast yellow. Cheeks and lores black. The eyelids and a 

 superciliary stripe, two bands on the wing and spots on the outer three tail feathers, white. Female of duller plumage and 

 browner above. Length, 5.65; extent, 9.25; wing, 3.00; tail, 2.50; iris brown ; bill and feet black. 



Sab. Eastern North America to the Missouri plains. Stragglers seen on Pugct Sound. 



On the 1st of May, 1856, I obtained a bird, which, according to the description in Audubon s 

 Synopsis, appeared to belong to the present species, the &quot; white throat &quot; being present. In 

 all other respects this bird resembled the S. Audubonii. It was shot in the same situation 

 frequented by birds of the latter species, and its habits appeared identical. S. 



I saw, on Whidby s island, in April, two of the yellow-crowned warbler, similar to the next, 

 and noticing the distinguishing white color of the chin, besides other less prominent differences, 

 I shot one. It seemed to agree exactly with the eastern bird, and is a curious but not the 

 only instance of two so closely allied species being found in the same region. As these are 

 the only ones I met with, it must be rare in the Territory. My specimen was unfortunately 

 lost. C.
