Sittacilla Lesson, Compl. de Buffon, ix, 1837, 135. (Type, Dendrocolaptes cune- 

 atus Lichtenstein.) 



Small Dendrocolaptidfe (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 anting 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 strongl}^ 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 seta?. 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 sub terminal 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 largo, very 

 strongly curved and acute, that of the hallux much less curved, 

 about as lonj; as the dij^it.
