GLOBE-BEARING CURASSOW.

This bird is rendered conspicuous by possessing 

 a globular tubercle, about the size of a hazle-nut 

 or cherry, on the base of the beak, which is covered 

 on that part with a lively yellow skin : the eyes are 

 surrounded with a small black naked space, which 

 is however separated from the cere by feathers : 

 the nostrils are placed before and below the tubercle 

 on the beak, in the yellow cere at its base : the 

 head has a crest, the feathers of which are turned 

 and frizzled, and are larger at their top than 

 towards their base : the whole of the plumage is 

 of a fine black, with a tinge of green ; but the 

 abdomen, the under tail-coverts, and the tips of 

 the tail-feathers, are white : the irides are chesnut- 

 brown : the beak and feet are dusky horn-colour. 

 The female scarcely differs from the male. The 

 young have a small protuberance in place of the 

 globose tubercle : their plumage is of a dull black, 

 transversely rayed with white, which rays dis- 

 appear as the bird increases in age, and by the 

 time it is two years old they are completely 

 obliterated. 



Hybrids between this and C. rubra have been 

 produced, which differ in the young state in 

 having the plumage of a dull black-brown hue ; 

 with the crest varied with black and white : the 

 abdomen reddish: the tail black, tipped with 

 white J the rest of the plumage striped with slender 

 transverse bars of white : the base of the beak 

 without tubercles : when grown up they have the 

 head and hind-part of the neck black : the crest 

 black, with a white band : the upper part of the
