(?) Automolus cervinigularis (not Anabates cervinigularis Sclater?) Zeledon, 

 Anal. Mus. Nac. Costa Rica, i, 1888, 113, part (Cartage, Costa Rica). 



Automolus cervinigularis exsertus Carriker, Ann. Carnegie Mus., vi, 1910, 641 

 (s. w. Costa Rica; crit.). 



Genus RHOPOCTITES Ridgway. 



Rhopoctitesa Ridgway, Proc. Biol. Soc. Wash., xxii, April 17, 1909, 72. (Type, 

 Philydor ru/o-brunneus Lawrence.) 



Medium sized to large Furnariidse (length about 165-210 mm.) 

 somewhat resembling the genus Automolus but with much stouter, 

 less compressed, and distinctly uncinate bUl, 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 antise 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 termmally, 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 setse. 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 pro- 

 truded 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; 



o 'Pai^ {pwTtbg), bush, underwood, brushwood; ktItijc, a colonist, inhabitant. 



b In the only specimen of Automolus ignohilis Sclater and Salvin available for 

 comparison, the tips of the rectrices are so much worn that the real length of the 

 tail can not be ascertained.
