The female wants the splendid crests which adorn 
the head of the male., but the other parts of her plu- 
mage will scarcely yield in brilliancy. The crown is 
rich ultramarine blue, and the dark gorget is distinctly 
marked ; the tail is of equal length, and with the 
nuchal collar and under parts are pure white; the 
hind head, back, and shoulders, are bright golden 
green ; the wings are purplish black.
