coverts are crimson, and consequently correspond in colour with the under tail-coverts. In the
birds thus distinguished the throat is orange, generally more intense in the middle, and either
fading gradually backwards, or giving place to a defined pale yellow band, separating the
throat from the crimson which immediately succeeds it. ‘The crimson of the breast varies in
extent, according to the species, from a broad band to one of so great breadth as to occupy the
entire breast. In one of the species the naked space surrounding the eye is blue; in the others
it is red.
