Mr. R. B. Sharpe’s Catalogue of Accipitres. 331 
Mr. Brooks’s paper is also valuable as containing a clear 
statement of the differences which exist between the A. rufo- 
nuchalis and A. hastata. 
Mr. Sharpe treats A. clang a and A. hastata as both being 
subspecies of A. rufonuchalis (his A. maculata) ; but as A. 
clanga has by far the widest geographical distribution of the 
three, I think it would be better to consider that Eagle as the 
leading species of the trio, and to allow A. rufonuchalis and 
A. hastata to occupy the position of subspecies. 
The confusion which has so long existed between A. clanga 
and A. rufonuchalis renders it difficult to decide with certainty 
to which of these two species many of the existing records of 
Spotted Eagles in reality apply ; and consequently it is by no 
means easy to define the respective geographical areas over 
which the two species range; but, independently of such am¬ 
biguous records, I believe that some definite and reliable in¬ 
formation on this head may be added to that supplied in Mr. 
Sharpe’s volume, and I will refer in the first instance to the 
geographical distribution of A. clanga , which is even more 
extended than the wide range recorded by Mr. Sharpe. 
With regard to the eastern range of this species, the third 
volume of the f Nouvelles Archives du Museum d’Histoire 
Naturelle de Paris ’ contains, at p. 29, a list of birds observed 
in Mongolia and Northern China by the Abbe Armand David, 
in which the following notes occur, of which perhaps both, 
but, I think, certainly the last, relate to this species :— 
“ No. 5.” An Eagle not named in the text, but identified 
in a footnote as “ Aquila planga, Pallas.” 
“ No. 7. Aquila ncevia , Br., de passage.” 
In f Stray Leathers/ vol. iii. p. 25, u Aquila clanga , Pall.,” 
is included in a list of the birds of Upper Pegu on the 
authority of a communication made to the editor by Captain 
Eeilden. 
There is also in the Norwich Museum an immature ex¬ 
ample of this species, which was formerly in the museum of 
the Zoological Society of London, where it was recorded as 
having been obtained in Sumatra by the late Sir Stamford 
Raffles.
