Sittacilla Lesson, Compl. de Buffon, ix, 1837, 185. (Type, Dendrocolaptes cune- 
atus Lichtenstein. ) 
Small Dendrocolaptide (length about 140 mm.) with bill much 
shorter than head, stout, wedge-shaped, with maxilla broad and 
flattened terminally; nostril narrow, broadly operculate, and tail 
(nearly as long as wing) with the very rigid rectrices very strongly 
decurved terminally. 
Bill much shorter than head, stout, wedge-shaped, its width at 
latero-frontal antie decidedly greater than its depth at same point 
and equal to about half the distance from nostril to tip of maxilla; 
culmen broad and rounded (not ridged), straight basally, rather 
suddenly depressed terminally, the tip of maxilla broad and rounded 
in vertical profile but acute in lateral aspect; maxillary tomium nearly 
straight, but slightly incised or faintly notched terminally; man- 
dibular tomium straight or very faintly concave (the mandible very 
slightly recurved terminally); gonys strongly convex and rather 
prominent basally, nearly straight and strongly ascending terminally. 
Nostril exposed, posteriorly in contact with latero-frontal feathering, 
narrow (slit-like), longitudinal, overhung by a very broad and con- 
spicuous operculum ,and, also margined below by the integument of 
the nasal fossa. Rictal bristles present but minute, and feathers of 
chin and lores with minute terminal sete. Wing moderate, rather 
pointed, the longer primaries exceeding secondaries by more than 
length of exposed culmen; seventh and eighth primaries longest, 
the tenth (outermost) about three-fourths as long as the longest, the 
ninth about equal to sixth. Tail nearly as long as wing, graduated 
for one-third, or more, of its length, the rectrices (12) acuminate, 
with the very strong and excessively rigid shafts very strongly 
decurved terminally. Tarsus much longer than culmen (from 
base); about one-fourth as long as wing, distinctly scutellate (endas- 
pidean); middle toe, with claw, decidedly shorter than tarsus; outer 
toe, with or without claw, as long as middle toe; inner toe, without 
claw, reaching to middle of subterminal phalanx of middle toe; 
hallux conspicuously shorter than inner toe, not stouter; middle toe 
united to outer toe for whole of first and part of second phalanx, 
to inner toe for whole of its first phalanx; anterior claws large, very 
strongly curved and acute, that of the hallux much less curved, 
about as long as the digit.
