“This species differs greatly in color from _P. iliaca_. It is darker in all parts; the feathers of the back are rufous-brown, centred with darker, instead of ash centred with brownish-red; the two white bands on the wing are wanting; the breast and throat are thickly streaked with elongated spots of dark reddish-brown, while in _P. iliaca_ the spots are less numerous, shorter and broader, and bright rufous, and the central part of the throat is nearly free from spots; the under tail-coverts are brownish-white, with rufous spots, instead of nearly pure white.” There are some features in this bird, as described by Mr. Verrill, which seem to characterize it as different from _P. iliaca_, although it is barely possible that it is this bird in immature dress. The streaked back at once separates it from all our species excepting _iliaca_. Nothing is said of its habits. One specimen was killed in Anticosti, July 1; the other, August 8. The true _iliaca_ was found on the island, which fact renders it still more probable that this is its young. Passerella townsendi, NUTTALL. TOWNSEND’S SPARROW. _? Emberiza unalaschkensis_, GMEL.

Emberiza (Zonotrichia) rufina_, KITTLITZ, Denkw. 1858, 200. (He compares it with _P. iliaca_, but says it is darker. Sitka.) SP. CHAR. Above very dark olive-brown, with a tinge of rufous, the color continuous and uniform throughout, without any trace of blotches or spots; the upper tail-coverts and outer edges of the wing and tail feathers rather lighter and brighter.

Side almost continuously like the back; tibiæ and under tail-coverts similar, the latter edged with paler. Axillars brown; paler on edges. Claws all very large and long; the hinder claw longer than its toe. First and sixth quills about equal. Length, about 7 inches; wing, about 3.00. HAB.
