(?) Automolus cervinigularis (not Anabates cervinigularis Sclater?) ZELEDON, 
Anal. Mus. Nac: Costa Rica, i, 1888, 113, part (Cartago, Costa Rica). 
Automolus cervinigularis exsertus CARRIKER, Ann. Carnegie Mus., vi, 1910, 641 
(8s. w. Costa Rica; crit.). 
Genus RHOPOCTITES Ridgway. 
Rhopoctites¢ Ripaway, Proc. Biol. Soc. Wash., xxii, April 17, 1909, 72. (Type, 
Philydor rufo-brunneus Lawrence.) 
Medium sized to large Furnariide (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 antiz 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 sete. 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. 
ignobilis 1°), 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; 
a*Pdd (dwxdc), bush, underwood, brushwood; xréryc, a colonist, inhabitant. 
bIn the only specimen of Automolus ignobilis 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.
