GEN. CHAR. Body thick, stout; legs large, toes reaching beyond the tail. Tail short, even, with narrow acuminate feathers. Bill slender, elongated; length about three times the height; commissure straight from the basal angle. Culmen flattened basally, extending backwards and parting the frontal feathers; longer than the head, but shorter than tarsus. Nostrils linear, covered by an incumbent membranous scale. Inner lateral toe longer than the outer, but not reaching to basal joint of middle; hind toe a little shorter than the middle, which is equal to the tarsus. Hind claw nearly twice as long as the middle. Feathers of head stiffened and bristly; the shafts of those above extended into a black seta. Tertials nearly equal to the primaries. Feathers above all transversely banded. Beneath yellow, with a black pectoral crescent. The only species which we can admit is the _S. magna_, though under this name we group several geographical races. They may be distinguished as follows:— Species and Varieties. 1. S. magna. Above brownish, or grayish, spotted and barred with black; crown divided by a median whitish stripe; side of the head whitish, with a blackish streak along upper edge of the auriculars. Beneath more or less yellowish, with a more or less distinct dusky crescent on the jugulum. Sides, flanks, and crissum whitish, streaked with dusky; lateral tail-feathers partly white. _Adult._ Supraloral spot, chin, throat, breast, and abdomen deep gamboge-yellow; pectoral crescent deep black. _Young._ The yellow only indicated; pectoral crescent obsolete. Length, about 9.00 to 10.50 inches. Sexes similar in color, but female much smaller. A. In spring birds, the lateral stripes of the vertex either continuous black, or with black largely predominating; the black spots on the back extending to the tip of the feather, or, if not, the brown tip not barred (except in winter dress). Yellow of the throat confined between the maxillæ, or just barely encroaching upon their lower edge. White of sides, flanks, and crissum strongly tinged with ochraceous. _a._ Pectoral crescent much more than half an inch wide. Wing, 4.50 to 5.00; culmen, 1.20 to 1.50; tarsus, 1.35 to 1.55; middle toe, 1.10 to 1.26 (extremes of a series of four adult males). Lateral stripe of the crown continuously black; black predominating on back and rump (heavy stripes on ochraceous ground). Light brown serrations on tertials and tail-feathers reaching nearly to the shaft (sometimes the terminal ones uninterrupted, isolating the black bars). _Hab._ Eastern United States var. _magna_.
