Eyloctistes " Ridgway, Proc. Biol. Soc. Wash., xxii, Apr. 17, 1909, 72. (Type, 

 Philydor virgatus Lawrence.) 



Rather large Fiirnariida? (length about 185 mm.) with bill nearly 

 as long as head (exposed cuhuen 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 antiae 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, w^here very shghtly 

 decurved; gonys nearly straight, ascending terminally slightly promi- 

 nent 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 

 cliin, etc., without termmal setfE. Whig moderate, rather pomted, 

 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 nmth intermediate between fourth and fifth and very much 

 longer than secondaries. Tail a httle 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, reachuig to slightly beyond middle of sub- 

 terminal 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; 



o- ''TXt}, a wood, forest; Kxcaxrig, a settler.
