Inhabits South America. Length thirteen inches 

 and a half : the feathers of the upper part and sides 

 of the head are black, firm, straight, decomposed, 

 and somewhat curled ; and appear, both to sight and 

 touch, of a velvety texture : they form a kind of crest 

 on the vertex as broad as the head : the top of the 

 head, the forehead, the fore part and sides of the 

 neck, as well as part of the breast, are fine plain 

 black : the occiput is bluish-^white, changing to a 

 beautiful bright azure on the nape, whence a deep 

 blue reigns over the back, wings, and chief part of 

 the tail, which is long and rounded at its tip ; over 

 the eye is a small spot of turquoise-blue and opal- 

 colour : on the eyelid is another, but of a deeper 

 blue, joined to a third of a triangular form, at the 

 base of the beak : the tip of the upper part of the 

 tail is white in the female and yellow in the male : 

 the basal half of the tail beneath is black, the tip 

 white : the beak and the legs are black ; the irides 

 are golden : the sexes differ somewhat beneath ; the 

 belly of the male being light yellow, and of the 

 female white. 



The eggs of this bird are whitish, tinged with 

 dirty-blue at the thickest end, and spotted through- 

 out with brown.
