Acci- Adult feimde : Above, dusky grayish brown, with transverse, rather distant, bars of dull white or light ochraceous. U'ing-coverts dark dull cinereous, broadly tijjped and bordered with white ; speculum dull black. Head and neck streaked with blackish ujion a dull whitish ground, the former color prevailing on the nape and behind the eye. Jugulum pale grayish vinaceous, the feathers darker beneath the surface ; sides and Hanks deeper vinaceous ; lower tail-coverts trans- versely spotted with l)rown ; rest of lower j)arts pure white, i'niuuj imih': Similar to the adult female, but the c(dors more pronounced and the pat- tern better defined, especially on tlie wing. Downy young: Above, dark olive, with a sepia tinge ; a spot of pale greenish fulvous on the posterior half of the wing, one on each side of the back, and one on each side of the rump. Lower parts, including head and neck, pale fulvous; a distinct blackish olive stripe from bill to and back from the eye, with a wide and con- spicuous superciliary stripe of fulvous above it. The chief variation in the plumage of adidt males of this species in the extent of the green patch and the amount of black spotting on the head, the pureness of the white on the forehead, and the extent of the white patch on the wing-coverts. The green patch on the side of the occiput is usually poorly de- fined, and broken up by lighter spotting ; but in No. 21-120, Washington, D. C, and No. 84712, from South- ern Ohio (Dr. F. W. Langdon), it is as conspicuous as in the adult male of Nettion carolinensis, and of very similar extent and form. Anteriorly, it sur- rounds the eye, and posteriorly it down the nape (where the two opposite spaces are con- fluent for the entire length of the neck); its outlines are firm throughout, and its surface is entirely unbroken by admixture of white.
