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.
