_Specific Character._--Bill black, short, and narrow; the outer webs of the first five secondaries black, tipped with white; the next five plain rich green, forming the speculum; secondary coverts tipped with pale reddish-buff. Adult male with a dusky band at the base of the bill, of which color is the throat; a faint white band under the eye; upper part of the neck, sides of the head, and the crown, chestnut brown; a broad band of bright green commencing behind the eye, passing down on the nape, where it is separated by the terminal portion of the crest, which is dark blue; lower part of the hind neck, a small space on the fore neck, and the sides of the body, undulated with lines of black and white; lower portion of the fore neck and upper part of the breast reddish-brown, distinctly marked with round spots of brownish-black; abdomen yellowish-white, faintly undulated with dusky; a patch of black under the tail; outer tail-feathers buff, inner white, with a large spot of black on the inner webs; tail brown, margined with whitish, the outer feathers greenish-black; upper parts brown, faintly undulated with black and white, on the fore part of the back; outer scapulars similar, with a portion of their outer webs black; lesser wing-coverts brown-ash; greater coverts tipped with reddish-cream; the first five secondaries velvety-black; the next five bright green, forming the speculum, which is bounded above by pale reddish-buff, and on each side by deep black; before the wing a transverse, broad white band. Female smaller; head and neck streaked with brownish-white and dusky, darker on the upper part of the head; lower parts reddish-brown, the feathers margined with dusky, upper parts dusky-brown, the feathers margined and spotted with pale reddish-white, without the chestnut red and the green on the head; the black patch is wanting, as is the white band before the wings, the conspicuous spot on the wings is less extensive. Its short and narrow bill is at all times a strong specific character; length fifteen inches; wing seven inches and a half. This is an excellent little duck, too confiding for its own security, but capable of saving itself by great rapidity of flight. It is greatly attracted by decoys, and will generally alight among them if permitted. BLUE-WINGED TEAL. _Anas Discors_, Wils.
