This bird closely resembles Anabazenops rvfo-superciliatus (Lafr.), 

 but may be recognized at oiice by the darker, browner back, and the 

 variegated head, which in the latter species is of the šame greeniah 

 brown as the back. In the present bird also there is not that decided 

 mottled plumage on the breast observable in the other species, 

 although there are slight indications of it on the sides of the neck.
