rictus, in a line beneath the eyes. The upper parts 

 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- 

 plish brown ; and the tail is composed of broad and 

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

 parts assume a grayer tinge ; and below, the white is 

 less pure, becoming browner on the flanks and vent. 

 The bill also wants its clearness, and the beautiful 

 azure crown only begins to appear as age advances. 

 The species has yet been only brought from Brasil.
