 j-egion to Arctic Ocean and Fort Yukon ; Panama, iu winter. Not noted at 

 Cape St. Lucas, in Mexico, or West Indies. 



(No. 18,322, %.) Top of head glossy black, with greenish lustre; back 

 and scapulars similar, but rather duller, and somewhat streaked by the 

 appearance of the white sides of the feathers — the bases of the feathers, 

 however, being plumbeous. Chin, throat, and sides of head chestnut brown, 

 this extending round on the nape as a distinct continuous collar, which is 

 bounded posteriorly by dull grayish ; the chestnut darkest on the chin, with 

 a rich purplish tinge. Rump above and on sides paler chestnut (sometimes 

 fading into whitish). Upper tail coverts grayish-brown, edged with paler, 

 lighter than the plain brown of the wings and tail. Forehead, for the length 

 of the bill, creamy white, somewhat lunate, or extending in an acute angle a 

 little over the eye ; a very narrow blackish frontlet ; loral region dusky to 

 the bill. A patch of glossy black in the lower part of the breast, and a few 

 black feathers in the extreme chin, the latter sometimes scarcely appreciable. 

 Under parts dull white, tinged with reddish-gray on the sides and inside of the 

 wings. Feathers of crissum brownish-gray, edged with whitish, with a tinge 

 of rufous anteriorly (sometimes almost inappreciable). 



(No. 18,322.) Total length, 5.10; wing, 4.50; tail, 2.40, nearly even; 

 difference of primary quills, 2.10; length of bill from forehead, .38, from 

 nostril, .25, along gape, .60, width, .50 ; tarsus, .48 ; middle toe and claw, .72, 

 claw alone, .22 ; hind toe and claw, .44, claw alone, .20. 



There is some variation in amount and shade of rufous in different 

 specimens. Usually there is none on the sides of body, and very 

 little at the base of the crissum. The rufous of the rump is always 

 lighter than that of the throat, where this color extends down on 

 the jugulum, with indistinct rounded outline behind, shading into 

 the smoky, reddish-gray of the sides of the breast. 



As in its allies, immaturity is shown longest in the absence or
