LIST OF DIURNAL BIRDS OF PRET.

' Here figured as "Aquila mogilnik." 



^ Figured by Mr. Dresser, from Volga specimens, under the name "Aquila nipa- 

 lensis." 



3 Neither Mr. Sharpe nor Mr. Dresser have separated A. orientalis and A. amurensis 

 from A. nipalensis ; but I am disposed to think that they merit subspecific separation 

 as distinguishable, though very closely allied, races. The first (very unfortunately 

 named) is the Western form, which seems to constitute a decidedly smaller race than 

 the more Eastern A. nipalensis of Northern India ; the second is only represented (as 

 regards the museums of Great Britain) by a single specimen from Amuria (the type), 

 now in the possession of Mr. Seebohm, who acquired it as a part of the collection left 

 by the late Mr. Swinhoe ; it is larger than any Indian example that I have examined • 

 but whether this excess of size is due to an individual peculiarity, or, as seems more 

 probable, is characteristic of the Amurian race, can only be ascertiuned by the acquisition 

 and comparison of additional specimens. If the Amurian race is distinct, it will 

 probably be the same as the Mongolian, referred to by Col. Prjevalsky in the passage 

 I have cited, under the name of "Aquila bifasciaia." 



* In September 1882 I saw, at the Zoological Society's Gardens in the Eegent's Park, 

 an adult A. rapax, said to have been obtained in Bulgaria, which was precisely similar 

 to two African adults in the same cage. 



' The specific name "ncevioides" is here used. 



^ One of these specimens is that figured in immature plumage in the ' Ibis' for 1865, 

 pi. 5, and is remarkable for having lived in confinement from 1864 to 1873 without 

 assuming the adult dress ; it was presented, when it died, by Lord Lilford to the 

 Norwich Museum.
