bles. Rest of the under neck whitish suffused into paler orange-chestnut

 feathers on the sides of the chest. 



The rest of the lower parts slaty black ; the sides and flanks quite black ; 

 the under tail-coverts deep black, with a green gloss. Under wing-coverts 

 and axillaries black, with a greenish purple gloss. Quills from below dark 

 bronzy green. 



Feet " carmine or scarlet " (C. Darwin). 



Iris " scarlet " (C. Darwin).

 probably refer to an adult bird in winter or to an immature individual. 



Female, eyes red, feet pink, bill black.
