Genus HYLOCTISTES Ridgway. 
Hyloctistes @ Rrpaway, Proc. Biol. Soc. Wash., xxii, Apr. 17, 1909, 72. (Type, 
Philydor virgatus Lawrence.) 
Rather large Furnariide (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 antiz 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 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 
chin, etc., without terminal sete. 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 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; 
@ ‘Ay, a wood, forest; xtéorn¢, a settler.
