of the wing ochraceous-white, with sparse, rather small, irregularly deltoid spots of dull rufous; under surface of the primaries unvaried white, as far as their emargination, beyond which they are black. Fourth quill longest; third a little shorter; second intermediate between fifth and sixth; first about equal to the ninth. _Female_ (extremes 30,969, Brookline, Mass., and 30,895, Mirador, Mexico; the latter the larger.) Wing, 11.00–11.30; tail, 6.80–7.10; tarsus, 2.30; middle toe, 1.30. _Male_ (32,309, Moose Factory, Hudson’s Bay Territory). Wing, 10.50; tail, 6.30; tarsus, 2.30; middle toe, 1.20. _Young male_, second year? (39,106, Remedios, Cuba, June; N. H. Bishop). Upper parts similar to adult, but a reddish tint appreciably washing the edges of the interscapulars and (less noticeably so) the scapulars. Bands on tail nearly as in adult; but very near the base is a fourth, very narrow and faintly defined, pale band, while the bases of all the feathers are much mottled with white. Dull rufous of the breast not continuous, but in the form of large longitudinal broad spots, occupying the greater middle portion of each feather; abdomen, sides, and tibiæ with smaller and more cordate spots of dull rufous; the lower tail-coverts immaculate; the decided ochraceous tinge beneath, deepest posteriorly. _Young_, first year (11,984, Washington, D. C.). The blackish above is much variegated, being broken by the narrow rusty borders to interscapulars, rump, and lesser wing-coverts; the broader and more ochraceous borders to scapulars and greater wing-coverts, and partially concealed whitish spotting on the former. Upper tail-coverts white, with broad bars of blackish-brown; secondaries and primaries edged terminally with whitish. Tail dull umber-brown, growing darker terminally; narrowly tipped with white, and crossed with six obscure, narrow bands of dusky, the (concealed) bases of all the feathers white. Superciliary region, cheeks, chin, throat, and entire lower parts, delicate pale ochraceous, or whitish cream-color; a conspicuous “mustache,” a medial longitudinal series of streaks on the throat, with large longitudinal ovate spots on sides of breast, cordate spots on sides and flanks, and sagittate spots on tibiæ, clear blackish-brown. The ochraceous deepest on the abdomen and crissum. Wing beneath as in adult. A very young bird, scarcely fledged (33,598, Milltown, Me.; G. A. Boardman), differs from the last in a much more continuous black shade above, the deeper ochraceous beneath, and larger, as well as more numerous, blackish spots beneath.
