 Genus HYLOCTISTES Ridgway.

Rather large Furnariidæ (length about 185 mm.) with bill nearly as long as head (exposed culmen longer than tarsus), basal phalanx of middle toe wholly adherent to both lateral toes, and with pileum, hindneck, back, foreneck, and chest streaked.

Bill about as long as head, rather narrow, straight, compressed, its width at loral antiæ decidedly less than its width at same point and equal to less than one-third the distance from nostril to tip of maxilla; culmen broadly ridged, nearly straight, slightly but decidedly decurved terminally, the tip of maxilla not uncinate; maxillary tomium faintly concave distally, without trace of subterminal notch; mandibular tomium nearly straight to near tip, where very slightly decurved; gonys nearly straight, ascending terminally slightly prominent and convex basally. Nostril exposed, posteriorly in contact (or nearly so) with loral feathering, rather broadly oval, longitudinal, non-operculate, with an inner oblique septum showing within the upper posterior portion. Rictal bristles wanting, and feathers of chin, etc., without terminal setæ. Wing moderate, rather pointed, the longest primaries exceeding secondaries by less than length of bill from nostril; sixth, seventh, and eighth primaries longest and nearly equal, the tenth (outermost) about two-thirds as long as the longest, the ninth intermediate between fourth and fifth and very much longer than secondaries. Tail a little less than five-sixths as long as wing, graduated for more than one-fourth its length, the rectrices (12) rather narrow, minutely acuminate terminally. Tarsus shorter than exposed culmen, about one-fourth as long as wing, rather stout, distinctly scutellate; middle toe, with claw, about as long as tarsus; outer toe, without claw, reaching to slightly beyond middle of subterminal phalanx of middle toe, the inner toe slightly but distinctly shorter; hallux about as long as inner toe, but decidedly stouter; basal phalanx of middle toe completely adherent to both lateral toes;
