 gion, including the wings and tail ; the shafts of the primaries, 

 secondaries and tail feathers brown ; the shafts of all the other 

 feathers black. Towards the primaries and tail, the blueish grey

 breast, belly, and vent reddish brown, barred with white, and 

 black shafts ; femorals like the belly with white shafts ; wing 

 surfaces white barred with brown, the white changing to an ashy

 verse pale brown bars, terminated by oblong, oblanceolate spots."
