■Ja^ b e -adult Female has never been-recognised by any authqr.;
nor, hitherto, even by. ourselves,* having been- misled hy otbprs' jn
taking the young for h er; and this we have only discovered by
inspecting a great many specimens. She is precisely similar to
the male, even in the minutest particulars, excepting the/.«absence
of yellow on the head, this part being of a rich and gloSsy black.
The young of both sexes are of -a dull blackish; the-setaceous
-feathers of the nostrils are grayish, somewhat tinged with rusty;
all-the feathers of the crown are tipped with whit#; constituting
thick dots on that part, to -which they giye a silvery appearance;

more or less varied with white, and the feathers* <of 'the back
being banded with white, gives to that part a waved appearance;
