" On migration tliis species was observed in great numbers, 

 togetlier with A. ylitschii, in the vicinity of Constantinople 

 by Mr. AUeon^ who erroneously named them A. clanga, 

 Pall., and A. ncevioides, Cuv. ; but we do not know the 

 winter-quarters of A. orient alis. 



" A. orient alis has been once obtained in the Government 

 of Moscow. 



" Aqiiila glitschii was probably found by Gmelin in the 

 steppes near the Lower Don ; but Gmelin's description being 

 insufficient, we cannot be certain of the identification. 

 Mr. Shatilov obtained a specimen of A. (/litschii in the Crimea 

 ( $ , IX. 1854), probably on migration. It is numerous about 

 the Sarpa, where it is more common than A. orientalis, with 

 which it is mingled there. Mr. Artzibashev has furnished 

 specimens of this Eagle from the steppes of Astrakhan. I 

 liave found and obtained specimens of A. glitschii in the 

 steppes near the river Ural, as far north as 400 versts from 

 the mouth, in the steppes near the river Emba, and in the 

 country between the Syr-Darja and Turgai (meridian of 

 Perovsk). A young specimen in my collection was obtained 

 in the hills north of Kuldscha (lat. 73°) ; an adult specimen 

 was furnished by Mr. Karelin for the Zoological Museum of 

 Moscow from the river Ajaghuz (lat. 48°), and many others 

 were obtained by General Kolpakovsky in Semirechje (now 

 preserved in the Zoological Museum of Moscow) . 



'^I infer from these facts that the breeding-range of ^. 

 glitschii extends from the Lower Don to the Black Irtysh, 

 across the Lower Volga, Ural, and the middle portion of the 

 Kirghiz steppes. From the river Ajaghuz its principal breed- 

 range extends throughout the breeding-range of A. bifas- 

 ciata, along the foot of Tarbagatai, Barlyx, Simirechensky 

 Alatau, and Erin-khabargha as far as Kuldscha. 



" On migration this Eagle was observed by Mr. Alleon 

 near Constantinople (the route to the Don and the Volga). 

 I found it on the route of migration which goes round the 

 northern and western foot of the Tiau-shan, from Aulje-ata 

 across Tchimkent to Tashkent ; and probably it is the same 

 species that I observed on migration across Karakum, near
