 * Automolus cervinigularis exsertus, Ann. Carnegie Mus., vi, 1910, 641 (s. w. Costa Rica; crit.).

 Genus RHOPOCTITES Ridgway.

Medium sized to large Furnariidæ (length about 165-210 mm.) somewhat resembling the genus Automolus but with much stouter, less compressed, and distinctly uncinate bill, culmen decidedly shorter than tarsus, rigid and protruding shafts to rectrices, and streaked coloration.

Bill nearly as long as head, stout, moderately compressed, its width at loral antiæ decidedly less than its depth at same point and contained slightly more than twice to about two and a half times in distance from nostril to tip of maxilla; culmen decidedly shorter than tarsus, distinctly ridged, nearly straight for basal half (more or less) strongly decurved terminally, the tip of maxilla distinctly uncinate; tomia nearly straight but slightly though distinctly decurved terminally, without trace of notch; gonys convex and rather prominent basally, ascending terminally, the tip sometimes faintly decurved. Nostril exposed, posteriorly in contact with loral feathering, roundish or broadly oval, nonoperculate but margined above by a very narrow membraneous rim. Rictal bristles absent, and feathers of chin, etc., without terminal setæ. Wing moderate, much rounded, the longest primaries exceeding secondaries by less than distance from nostril to tip of maxilla; sixth and seventh, or fifth, sixth, and seventh, primaries longest, the tenth (outermost) about two-thirds as long as the longest, the ninth about as long as secondaries. Tail about as long as wing (decidedly shorter in R. ignohilis? ), graduated for about one- third its length, the rectrices (12) rather loosely webbed or semi-decomposed, with rigid and protruded shafts. Tarsus longer than culmen, about one-third as long as wing, rather stout, distinctly scutellate; middle toe, with claw, slightly shorter than tarsus; outer toe, without claw, reaching to about middle of subterminal phalanx of middle toe, the inner toe slightly shorter; hallux about as long as inner toe but much stouter;
