beneath the eyes. The irides are yellowish-white. 
Immediately beneath the under mandible is a broad 
black fascia, extending upwards to the ears, and en- 
compassing the greater part of the naked white space. 
The whole of the upper plumage is of a beautiful 
rich blue, passing into green upon the forehead, 
crown, rump, and some of the smaller wing-coverts. 
The greater quills and tail are of a deeper tint, ap-

and tail are yellow. The sides of the neck, breast, 
and inferior parts of the body, are rich saffron-yel-

defined by whitish lines. Like all the other mem-

and is met with in the Brazils, particularly upon the 
banks of the river Amazons, in Guiana, and Suri- 
nam, &c. It affects the woods, particularly such as 
occupy swampy grounds, and which abound in a 
species of palm, upon whose fruit it principally sub- 
sists. It is said generally to keep in pairs, though

that in this respect they are inferior to none of the 
tribe, their flight being often at a high elevation,

the summits of the highest trees. They deposit their
