Descriptions of Three New Birds from the Belgian Congo
“ The adult male of A. minus is distinguished by the bluer hue of the forehead, throat, and upper breast, which show in certain lights deep violet reflections, and by the more scarlet, less crimson color of the remaining underparts. In life the naked areas on the cheeks are bright yellow, whereas in A. narina they are light green.The adult female differs in the more tawny or ochraceous coloration of the breast, which is grayish in this sex of A. narina, although sometimes washed with light brown on the upper breast. A greenish gloss on the upper breast is more common in females of A. narina. ”
