Adult $ : The feathers of the head somewhat full and puffy, though forming no crest. Bill broad and ilattened, a little widened toward end, running into ^^^~' '»" the forehead which arches abruptly over and away from it, not rising gradually into line with forehead; shorter or not longer than head, 3 inches or less in length along culraen, the nostrils within its basal half; the forward end of nostril about f the way from upper corner to end of bill. Bill dull blue with a black belt at the end. (Compare head and bOl of canvas-back.) Iris orange. Feet dull grayish-blue, with dusky webs and black claws. Head and neck all around rich pure chestnut, not obscured with dusky-brown, but with bronzy or coppery red reflections. Lower neck and fore parts of body above and below, with rump and taU-coverts above and below, blackish. Back mixed whitish and blackish in about equal amounts, the dark wavy lines distinct and unbroken. (In the European pochard, F. ferima, from which our bird differs, the back is also distinctly and completely waved with black, but the ground is quite white, as in our canvas-back, in which the dark lines are much broken up, the white thus prevailing. This fine vermiculation, when not too closely examined, gives a delicate sUvery-gray tone, of diflferent shade in the different species.) Sides of body under the wings vermiculated much like the back, the undulations
