tipped rectrices, and inner webs of remiges crossed by a broad oblique band of light tawny or ochraceous-buff.

Bill decidedly shorter than head, stout, wedge-shaped, compressed, its width at loral antiæ much less than its depth at same point and equal to a little less than half to one-third the distance from nostril to tip of maxilla; culmen scarcely ridged, straight to extreme tip; maxillary tomium slightly convex, without trace of notch; mandibular tomium distinctly concave for terminal half, without trace of notch; gonys distinctly convex, strongly ascending terminally, the mandible strongly recurved terminally (falcate) with tip acute. Nostril exposed, posteriorly in contact with loral feathering, very small, longitudinally ovate or elliptical, slightly operculate. Rictal bristles absent. Wing moderate, rather pointed, the longest primaries exceeding secondaries by length of culmen, or more; seventh and eighth primaries longest, the tenth (outermost) about four-fifths as long as longest and decidedly longer than secondaries. Tail a little more than two-thirds to four-fifths as long as wing, strongly rounded or moderately graduated (graduation not greater than length of tarsus), the rectrices (12) soft and rounded terminally. Tarsus as long as or slightly longer than culmen, one-fourth as long as wing or slightly less, distinctly scutellate; middle toe, with claw, about as long as tarsus; outer toe, without claw, reaching to middle of subterminal phalanx of middle toe, the inner toe slightly but decidedly shorter; hallux as long as outer toe, decidedly stouter; middle toe united to outer toe by all of its first and half or more of its second phalanx, to inner toe by whole of its first phalanx; claws large, strongly curved, acute, that of the hallux much shorter than the digit.

Coloration. — Plain brown or rufescent above, the head darker, sometimes streaked; tail cinnamon-rufous with much black on third and fourth, or second, third, and fourth rectrices; primaries blackish and dull cinnamon-rufous; inner webs of remiges crossed obliquely by a broad band of pale tawny or ochraceous; under parts light olive, whitish on throat, the chest, etc., sometimes streaked with whitish. Sexes alike.

Range. — Southern Mexico to Cayenne, Brazil, Bolivia, and Peru. (About five species.)[1]
