Mr. R. B. Sharpe's Catalogue q/" 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. clanga 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 ' 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 ' Stray Feathers,^ vol. iii. p. 25, " 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 

 Feilden. 



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.
