123. (New name for Pittasoma Cassin, on grounds of purism.) 
Very large Formicariide (length about 160-180 mm.) with exces- 
sively short tail (shorter than commissure, only one-third as long as 
the short, much-rounded wing), stout, distinctly uncinate, bill, very 
long tarsi (half as long as wing), and conspicuously variegated 
coloration. 
Bill nearly as long as head, stout, rather broad and slightly depressed 
basally, its width at loral antize much greater than its height at same 
point and equal to half the distance from nostril to tip of maxilla, or 
slightly more; culmen distinctly but not sharply ridged, slightly 
curved from near base to near tip, where more strongly decurved, the 
tip of maxilla strongly uncinate; maxillary tomium straight or very 
faintly concave, distinctly notched subterminally; mandibular 
tomium faintly convex, slightly but distinctly notched subterminally ; 
gonys strongly convex and prominent basally, nearly straight. for 
most of its length, ascending terminally, the tip of the mandible 
forming an obtuse, slightly recurved, point. Nostril exposed, poste- 
riorly in contact with loral feathering, longitudinally oval, with a 
thin, pointed, internal tubercle or splint in upper posterior portion. 
Rictal bristles present but short and inconspicuous. Wing rather 
short, much rounded, the longest primaries scarcely if at all extending 
beyond secondaries; fifth and sixth, or fourth, fifth, and sixth, pri- 
maries longest, the tenth (outermost) less than two-thirds as long as 
the longest, the ninth much shorter than secondaries. Tail exces- 
sively short, shorter than commissure, only one-third as long as wing, 
the rectrices relatively broad. Tarsus much longer than commissure, 
half as long as wing, stout, rounded posteriorly, distinctly scutellate, 
the plantar scutella indistinct (fused on upper half or more); middle 
toe, with claw, about three-fourths as long as tarsus; outer toe, with- 
out claw, reaching to a little beyond subterminal articulation of mid-
