FALCO CHEYSAETOS AND F. FULVUS. 4S3 
With respect to Mr Wilson''s remark, that although 
the adult specimen of the Golden Eagle in the Sprunglian 
Cabinet at Berne, appears to bear a close resemblance to 
that in the Parisian Cabinet ; yet, that the supposed young 
of this species in the latter collection, answering the descrip- 
tion of the F.fulvus^ or Bing-tailed Eagle, is different from 
the young of the Golden Eagle preserved by M. Sprungli, 
I beg to suggest, that this specimen may perhaps be the 
Falco imperialis of Temminck, the F, mogllhik of authors, 
—a bird which, in its mature state, closely resembles in 
plumage the Golden Eagle, F. clirysaetos. It is also called 
Gold-adler by some of the German writers ; and what in- 
clines me to think that this may be the case, is, that Mr 
Wilson''s description of this young Golden Eagle, ap^ 
proaches very near to that given by M. Temminck of the 
young Aigle imperial, Falco imperialism or mogilJiik. It 
is therefore upon the evidence of ocular demonstration, and 
the concurrent testimony of others who have made the like 
experiments with living birds, that I ground my opinion 
of the identity of the Golden and Ring-tailed Eagles ; and 
I venture to hope, that, in removing this Ring-tailed Eagle, 
as well as the Sea Eagle (Falco ossifragus), from the sta- 
tion they occupy in the British Fauna, as distinct species, 
I shall not incur the imputation of having done so, without 
due consideration, or sufficient and satisfactory grounds,
