The above characters are those of a large series of specimens from Sitka, and a few points along the coast to the southward and northward, and represent the average features of a race which is intermediate between _guttata_ and _insignis_, in appearance as well as in habitat. Tracing this variety toward the Columbia River, it gradually passes into the former, and northward into the latter. We have no distinctive information relative to the habits of this race. Melospiza melodia, var. insignis, BAIRD. KODIAK SONG SPARROW. _? Fringilla cinerea_, GMELIN, I, 1788, 922 (based on Cinereous Finch, LATH. II, 274).—PENN. Arc. Zoöl. II, 68 (Unalaschka). _Emberiza cinerea_, BONAP. Consp. 1850, 478. _Melospiza insignis_, BAIRD, Trans. Chicago Acad. I, ii, 1869, p. 319, pl. xxix, fig. 2.—DALL & BANNISTER, do. p. 285.—FINSCH, Abh. Nat. III, 1872, 44 (Kodiak). SP. CHAR. _Summer plumage_ (52,477 ♂, Kodiak, May 24, 1868). Above brownish-plumbeous, outer surface of wings somewhat more brown, the greater coverts slightly rufescent. Interscapulars with medial broad but obsolete streaks of sepia-brown; crown and upper tail-coverts with more sharply defined and narrower dusky shaft-streaks. Crown without medial light line. Beneath grayish-white, much obscured by brownish-plumbeous laterally. A whitish supraloral space, but no appreciable superciliary stripe; a whitish maxillary stripe; beneath it an irregular one of dusky sepia; irregular streaks of dark grizzly-sepia on breast and along sides, blended into a broad crescent across the jugulum. Wing, 3.30; tail, 3.50; bill, .48 from nostril, .28 deep at base, and .21 in the middle, the middle of the culmen being much depressed, its extremity rather abruptly decurved. _Autumnal plumage_ (60,162, Kodiak, received from Dr. J. F. Brandt). Differs very remarkably in appearance from the preceding. The pattern of coloration is everywhere plainly plotted, there being a distinct vertical and sharply defined superciliary stripe. Ground-color above ashy, somewhat overlaid by rusty, except on the sides of the neck. Whole crown, outer surface of wings, and dorsal streaks, rusty rufous; black streaks on crown and upper tail-coverts obsolete. Beneath pure white medially, the markings rusty rufous. Wing, 3.30; tail, 3.60; bill, .47 and .30. HAB. Kodiak and Unalaschka. This race represents the extreme extent of variation in the species, and it would be difficult for a species to proceed farther from the normal standard; indeed, the present bird is so different even in form, especially of bill, from _melodia_, that, were it not for the perfect series connecting them, few naturalists would hesitate to place them in different genera. HABITS. No information has so far been published in reference to the nesting of this Sparrow, or of any peculiar habits. Melospiza lincolni, BAIRD. LINCOLN’S FINCH.
