THE CHILIAN SEA-EAGLE. 87 



its surface ; the upper wing-coverts ash-coloured, with 

 blackish' stems and transverse hnes of the same ; and 

 the larger coverts, as well 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 ha\-ing 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 yellow ; the 

 beak black at its point and blue at the base ; and the 

 iris of a very light hazel. 



To this description M. Temminck adds that the tarsi 

 are naked on the greater part of their anterior surface, 

 but plumed towards the joint of the knee, while they 

 are entirely naked on the back and sides. He describes 

 the head and upper parts as of a deep bluish ash or 

 nearly slate-colour ; the tail-feathers terminating in a 

 small white spot ; the sides of the neck and the breast 

 of a light bluish ash-colour, more or less marbled with 

 whitish, and with a small white spot at the extremity 

 of each of the feathers. The upper parts of the sides, 

 and all the under wing and tail -coverts, are white, 

 marked by fine very distant rays of bluish ash-colour. 

 All the rest of the under surface and the legs are pure 

 white. The feathers of the throat are whitish, marked 

 by ash-coloured stripes resulting from the sombre tinge 

 of their stems ; the wings are of a lighter ash-colour 

 than the back ; all the coverts, together with the quills, 

 have numerous slate-coloured rays, and their stems have 

 the same hue. 



Such are the descriptions of D'Azara and Temminck, 

 evidently taken from birds in different states of plumage, 

 and both of them differing as much from the Society's 

 specimen as from each other. The latter, which may
