 black ; the feathers of the upper mantle and scapulars have 

 broad, rusty-brown edges ; the wings are blackish-brown, with 

 an obscure bronzy-brown speculum ; the whole of the head 

 and neck, as well as the entire breast, are blackish-brown, some- 

 what paler and more chocolate-brown on the latter ; lores and 

 fore-part of cheeks white, extending in a patch behind the

 lars and rump especially showing the olive-grey tinge ; wings 

 brown, the feathers edged with grey, but showing no distinct 

 speculum ; crown of head blackish-brown, sharply defined
