be regarded as fully adult, having been for nearly three 

 years an inhabitant of the Garden, agrees very well in the 

 general colour of the upper surface with the bird figured 

 by the latter author. It was nearly of a uniform brown 

 when it first arrived in England, but in its present state 

 its head, neck, breast, and back, are of a grayish slate- 

 colour, each of the feathers of the latter parts termi- 

 nating in a small white tip. The upper part of the 

 throat is considerably lighter than the rest. The upper 

 wing-coverts are of the same colour as the back, but 

 without the lighter tips ; the intermediate are grayish 

 with a stripe of slate-colour along the middle, and 

 immerous rather broad transverse wavy bars of the 

 same ; the lower are similar in colour to the upper ; as 

 are also the quills themselves, with the addition of 

 some faint transverse grayish bars, which are more 

 visible at the base than towards the tips. The quill- 

 feathers of the tail are of the same uniform slaty hue 

 as the back, with dirty white tips beneath. On the 

 whole of the under surface, from the breast backwards, 

 and on the feathered part of the legs, the ground-colour 

 is white, faintly barred by numerous transverse narrow 

 wavy lines of a grayish brown. The legs and cere are 

 of a light straw-colour ; the beak light at the base and 

 bluish black in the hook ; the claws black ; and the 

 irides hazel. The nostrils are peculiar in their direc- 

 tion ; instead of being transverse or directed obliquely 

 backwards and downwards, as in the rest of the genus, 

 they are nearly horizontal, the long diameter of their 

 oval being parallel with the upper edge of the beak. 



In addition to the habitat given by D'Azara, M. Tem- 

 minck mentions Brazil, in certain parts of which, he 

 says, these Eagles are more common, and where they 

 are known by the name of Aguia. Our specimen came 

 from Chili.
