 and inner edges of the outer quills, white. Tail feathers uniform black. 



Female with the red confined to the occipital crest, the rest replaced by greenish black ; the three patches white, black, and 

 red, very sharply defined. Length about 9 inches ; wing about 5.

 behind the sulphur yellow crescent. The white of the breast is streaked with black ; the 

 posterior portion of the black of the breast and anterior belly streaked with white. The white 

 of the wing only shows externally as a patch at the base of the primaries.
