$, in summer: Upper parts rich olive, inclining to grayish on the head, 

 brightest on the rump. Wings and tail brown, edged with the color of the 

 back. Chin, throat, and breast, with under wing- and tail-coverts, rich yel- 

 low. Middle under parts dull whitish, shaded on the sides. A broad black 

 mask on the front and sides of the head, bordered behin d by hoary-ash. Bill 

 black; feet flesh-colored. Length, 4f-5; extent, GJ-Cf ; wing, 2; tail rather 

 more. 



$ , in summer : Similar to the male ; rather smaller ; yellow of the under 

 parts paler and more restricted ; no black or ashy markings on head, but 

 crown usually with some concealed reddish-brown. Otherwise top and sides 

 of head like back, with some obscure whitishuess about the lores and orbits. 



Young : Similar to the adult female, but the olive of the upper parts with 

 much of a brownish tinge, the yellow parts buflfy, and, in fact, most of the 

 under parts quite buffy. 



The adults, in fall and winter, are similar to each other, except in the 

 purer and stronger yellow of the male, as at that season the pecubar black 

 and ashy markings of the head are wanting. Both sexes then resemble the 

 autumnal plumage of the young in the browner shade of the olive and 

 bn£Bness of the under parts.
