the under mandible of the beak to the coverts of 

 the ears extends a black stripe ; and a stripe of 

 white exists, reaching from the base of the beak 

 to the ears, passing over the naked space on the 

 temples : the feathers on the top of the back are 

 ashy-green, with their margins grey; the wing- 

 coverts, secondary feathers, and tail-coverts, are 

 shaded with deep green ; and the whole of the 

 feathers are edged with a broad band of fine red: 

 the tail is greenish, tinged with rosaceous: the 

 lower part of the neck, the breast, and the belly, 

 are grey-brown, each feather being bordered with 

 whitish : the thighs, the abdomen, and the rump, 

 are of a chesnut-colour : the throat and the upper 

 part of the neck are naked and red, and are fur- 

 nished with a loose hairy membrane : the naked 

 skin on the sides of the head, which joins the base 

 of the beak, is of a deep purple : the irides are 

 reddish-brown : the feet are horn-coloured ; and 

 the claws and beak are brown. Female similar. 

 The young after attaining the length of fifteen 

 inches do not differ from the above. The adult 

 bird is two feet and upwards in length : it inhabits 

 Brasil, and by the Indians of the district of Para 

 is called Jacu-peea.
