. Review of American birds in the Museum of the Smithsonian Institution: pt. 1 . Birds. 404 REVIEW OP AMERICAN BIRDS. [part I. Bomhycilla, Vieillot, Ois. Am. Sept. I, 1807, 88. (Type B. cedrorum.-) "Bombyciphora, Meyeh, 1810" (Gray). —"Bomftjciwom, Temh. 1815" (Gray). Body stout, compact; plumage silky and soft. Wings long and much pointed, considerably longer than the narrow, nearly even tail. An extremely. Ampelis garrula, Lnw. small first primary, which sometimes is visible on the inner side of the base of the second quill, sometimes rests on the outer side as in other Oscines sup- posed to have only nine primaries (see pages 160, 325). The 2d quill is nearly as long as the 3d ; the remaining primaries graduate very rapidly to the 10th, which reaches scarcely beyond half the exposed portion of 3d. The shafts of the secondaries are tipped by a flattened, obovate horny appendage of a bright red color, like sealing wax ; traces of something similar to which may sometimes be seen on the tail. The tail is narrow and nearly even. Bill short, deeply cleft, depressed, and broad at the base, the width' of mouth more than two-thirds the commissure; the culmen and gonys con- siderably less than half the gape, and both much curved from base, the com- missure nearly straight. The tip of upper mandible is decurved, deeply notched, and with a decided tooth behind the notch; lower bill slightly notched. The nasal fossae are filled with soft, short, erect, velvety feathers, advancing far forward close along the upper edge of nostrils, and concealing them ; the nostrils are much elongated, and narrowly elliptical. The rictal bristles appear to be wanting, although a few short ones overhang the base of the bill. The tongue is broad, fleshy, sagittate behind, horny and bifid at the tip. The legs are short, but stout; the tarsus scarcely longer than the middle toe without claw: decidedly shorter than the entire toe ; distinctly scntellate: five or six divisions
