Dendromanes ScuaTeR, Proc. Zool. Soc. Lond., 1859, 382. (Type, Dendrocincla 
.anabatina Sclater.) 
Medium-sized to rather large Dendrocolaptide (ength about 
175-235 mm.), with narrow, conspicuously operculate nostril, bill as 
long as or longer than head, with distinctly recurved (almost uncinate) 
tip, and with tail shorter than wing, graduated for about one-third its 
length, the tips of rectrices inconspicuously acuminate and with the 
nearly denuded projecting tips of the very rigid shafts but slightly 
decurved. 
Bill about as long as, sometimes slightly shorter than, head, rather 
stout, nearly straight (but distinctly decurved, almost uncinate, at tip), 
its width at latero-frontal antiz equal to or greater than its depth at 
same point, and contained from less than two and a half to a little 
more than three times in the distance from nostril to tip of maxilla; 
culmen more or less distinctly ridged, straight for most of its length, 
rather abruptly decurved terminally, the tip of maxilla almost 
uncinate; maxillary tomium straight for the most part, rather 
strongly concave (decurved) terminally, without trace of notch; 
gonys more or less strongly convex and prominent basally, straight 
and ascending terminally, the extreme tip sometimes slightly 
decurved. Nostril exposed, posteriorly in contact with feathering 
of latero-frontal antie, narrow (slit-like), longitudinal, overhung by 
a broad membranous operculum, this sometimes partly covered by 
feathers of the latero-frontal antiz. Rictal bristles present but very 
small, and feathers of chin and lores with fine terminal sete. Wing 
moderate to rather long, rather pointed, the longest primaries exceed- 
ing secondaries by from less the distance from nostril to tip of maxilla 
to nearly length of exposed culmen; sixth, seventh, and eighth, orsixth 
and seventh, primaries longest, the tenth (outermost) a little more
