The commonest species, called 



Cushew Curassow. Crax Pauxi. Lin. Enl. 78. 

 Vieill. Galer. 200. 



Carries at the base of the bill an oval tubercle, nearly 

 as thick as the head, of a bright blue colour, and 

 stony hardness. This bird is black, but about the 

 vent and at the end of the tail, white. It lays on the 

 ground. Its native country is not certainly known. 

 The trachea descends on the outside, along the right 

 side to behind the sternum, bends toward the left 

 side, and returns in front to enter the chest by the 

 furca. AU its rings are compressed.* 



There is another species, which has in stead of 

 a tubercle, a mere salient crest on the bill, which is 

 red. Its belly, and the end of the tail, are marron. 

 This is the true Mitu of Margrave.
