of the body are of a brilliant golden green, and the 
under parts of a chaste and clear white ; the wings 
are large, equaling the tail in length, and of a pur-

strong feathers. In the birds of one year, the upper

less pure, becoming browner on the flanks and vent.

azure crown only begins to appear as age advances. 
The species has yet been only brought from Brasil.
