Genus PHAANOSTICTUS Ridgway. 
Phznostictus 4 Ripaway, Proc. Biol. Soc. Wash., xxii, Apr. 17, 1909, 70. (Type, 
Phlogopsis mcleannani Lawrence.) 
Medium-sized or rather large Formicariide (length about 190 mm.) 
with bill stout and about as long as head, tail nearly as long as wing, 
tarsal scutella fused, sides of head naked, and with back and under 
parts conspicuously spotted with black. 
Bill about as long as head, rather stout, moderately compressed 
terminally, its width at latero-frontal antiz decidedly less than its 
depth at same point; culmen distinctly (almost sharply) ridged, 
nearly straight for most of its length, or very slightly convex sub- 
basally, decurved terminally, the tip of maxilla moderately uncinate; 
maxillary tomium nearly straight, slightly notched subterminally; 
mandibular tomium straight, minutely notched subterminally; 
gonys decidedly convex and prominent basally, faintly convex and 
ascending terminally. Nostril exposed, posteriorly in contact with 
thin feathering of latero-frontal antiz, broadly oval, margined above 
by a rather broad extension of the membraneous integument of the 
nasal fosse, an internal tubercle showing distinctly within posterior 
portion. Rictal bristles absent, but feathers of loral region with 
stiffened, bristle-like shafts. Wing moderate or rather large, with 
longest primaries extending considerably beyond secondaries; sixth, 
or fifth, sixth and seventh, primaries longest, the tenth (outermost) 
nearly two-thirds as long as the longest, the ninth about as long as 
secondaries. Tail of 12 rectrices, nearly as long as wing, graduated 
(graduation equal to length of tarsus or for about two-fifths its length), 
the rectrices rather narrow, rounded terminally. Tarsus a little more 
than one-third as long as wing, stout, booted (nonscutellate); middle 
toe, with claw, decidedly shorter than tarsus; outer toe, without 
claw, reaching to about middle of subterminal phalanx of middle 
« @aivw, I display, exhibit; otexréc, marked, spotted.
