with recurved feathers terminating in stiff bristles; outline of culmen and gonys modera- 
tely convex; lower mandible obsoletely notched. Facial disk not conspicuously defined, 
imperfect behind the eyes. Wings exceedingly long, much rounded, the exposed 
portion of the first primary only two thirds that of the longest one; third and 
fourth longest, fifth but little shorter, second about equal to the sixth. Tail of 
moderate length, not graduated; rectrices broad to their very tips. Tarsi of 
moderate length, feathered only for a short distance below the tibiotarsal joint: 
the rest of their extent and the superior surface of the toes, clothed with bristly 
hairs. Claws unusually small and weak, moderately curved; the outer one reaching 
a little beyond the base of the middle one; the inner intermediate between outer 
and middle ones. Middle toe and claw about as long as the tarsus. Hallux 
elongated.
