. The birds of America : from drawings made in the United States and their territories . ender, slightly concave above,trigonal, tapering to a thin hornypoint. (Esophagus S inches long, ^inch in width along the neck. Theproventriculus, b c, forms a verylarge sac, as in the other species, 10twelfths in width; but the stomach,c d e f, although still very large, ismore muscular in structure, and ap-proaches in character to a true giz-zard. It is of an irregularly ellipticalform, If inches long, \% inches broad;there are distinct lateral muscles 5twelfths thick, a very prominent in-ferior muscle, e, and large oblongtendons. The epithelium is verythick, dense, tough, with remarkablystrong longitudinal rugae, transverselyfissured, and also lining the largepyloric cavity,/, which is S twelfthsin extent. The pro ventricular glands are exceedingly large, those in themiddle being 3 twelfths long, and i twelfth broad; they form a belt Hinches in breadth. The intestine forms 8 folds, and measures 31 inches inlength; its width at the upper part is 3i twelfths, at the lower 3 THE PIED-BILLED DOBCHICK. 329 The cceca are only 3 twelfths long, and 1 twelfth broad. The cloaca isglobular, and of moderate size. The trachea is 5 inches 10 twelfths long, much flattened; If twelfths inbreadth, toward the lower part 2 twelfths, and lastly contracted to 1^-twelfths; the rings 150. The bronchi differ in this species from the rest inbeing composed of distinctly separated cartilaginous half rings, 15 in muscles as in the other species. In another individual, a female, the stomach is of a regularly ellipticalform, 1 inch 9 twelfths long, 1^ inches in breadth; the muscular coat ofmoderate thickness, composed of strong fasciculi; the epithelium thinner andmore corrugated. The stomach contains a great quantity of feathers, scalesof fishes, numerous elytra of aquatic coleoptera, and a fish 3 inches long, and11 twelfths in depth. It is very remarkable, and equally singular, tha
