American animals, as well as for the most authentic details with respect to 

 their native habits. In the present instance he has unfortunately given u* 

 no such particulars ; and as no other zoologist has seen the living bird in a 

 state of nature, we can but judge from analogy that its manners are the same 

 with those of the best known species of its genus. A figure taken from a 

 preserved specimen, has been lately published by M. Temminck, in his 

 splendid Planches Colorizes; and the description which accompanies it, is 

 the only original notice of the bird subsequent to that of M. D'Azara. 



The latter author, or rather his French translator, names it l'aigle 

 noiratre et blanc. He states, that it is found, but not frequently, in Para- 

 guay, and that it is generally seen in pairs. The feathers of the head, neck, 

 and upper part of the body, are, according to his description, of a blackish 

 blue, and, with the exception of those of the back, terminated by dirty white. 

 The tail is blackish, with small whitish spots scattered over its surface the 

 upper wing-coverts ash colored, with blackish stems and transverse lines of 

 the same ; and the large coverts, as wt <' as the quill-feathers, of a deeper 

 ash. variegated with narrow black bands. The whole under surface is 

 beautifully white, with transverse blackish lines on the under tail-coverts, 

 and larger wing-coverts alone ; the smaller wing-coverts having no other 

 part but their stems of this sombre tinge. The naked part of the leg is of a 

 light yellow, with large flat scales both before and behind ; the cere is pale 

 vellow ; the beak black at its point, and blue at the base ; and the iris of a 

 very light hazel.
