bold black spots near their ends and occasionally white tips; sides of 
the head and sides of the neck rufous like the crown; remainder of the 
under parts white, with the blackish bars on the throat and chest broader 
than in the adult.” (Shelley.)

Genus CACOMANTIS S8. Miller, 1843. 
Size small; wing short and pointed; third primary longest; primaries 
exceeding secondaries by one-third of length of wing; tail strongly grad-
