146 W. E. Brooks — On Aqicila hifasciata. [No. 2, 



alternative, but to come to the conclusion that A. orientalis is identical in 

 every respect with A. hifasciata* 



I have now, therefore, three European killed examples of A. hifasciata ; 

 the third being that sent me by Capt. Elwes, and referred to in " Stray Fea- 

 thers," Vol. I, p. 291. The two first are in nearly mature plumage, and the 

 third is quite mature ; and is the finest specimen of the bird I have seen. 



The two sent as " A. orientalis'' have only slight indications of the 

 nuchal patch ; otherwise I should have recognized them at the first glance 

 as A. hifasciata, as was the case with Capt. Elwes's Bosphorus bird. This 

 term has, I believe, priority over A. orientalis, Cabanis, and if so will be 

 retained for this eagle. 



The application of Pallas's term " A. clanga'"' to the same species by 

 some European writers is, I believe, an error, if I read the original descrip- 

 tion correctly. It appears to refer to our Indian spotted eagle which we 

 accept as Aq^. ncBvia, and which I believe to be the true ncevia. Klein, 

 whose work is dated 1750, is the author of the term Aquila clanga, and 

 Pallas quotes and adopts this synonym in preference to the older term 

 Aquila ncevia, Schwenckfield. This term Pallas also quotes under the head 

 of Aquila clanga, but as a synonym. Schwenckfield's work is dated 1603. 



In a letter received the other day from my friend Mr. Anderson, he 

 records the occurrence of a lineated A. Mogilnih at Aden, which was 

 stunned by flying against the telegraph wires there. 



I may as well mention here that the Indian Imperial Eagle, to which 

 I applied Hodgson's term of A. crassipes, is identical with the East 

 European bird, A. Mogilnih, better known as A. imperialis, but the former 

 is the prior term. 



I compared our bird with an adult Turkish specimen sent me by Dr. 

 Bree. Mr. G-urney also came to the same conclusion, after comparing the 

 adult Indian birds, I had sent home, with European examples. 



The West European Imperial Eagle is, however, quite distinct and is 

 now known as A. Adalherti, Brehm. This is the species said to have no 

 lineated stage, and having, when adult, an excess of white on the scapulars 

 and ridge of wing. 



* [Mr. V. Ball and I had the pleasure of comparing the two specimens of A. 

 orientalis, referred to by Mr. Brooks, with a series of Indian A. hifasciata. They un- 

 doubtedly appear to be perfectly identical, both in structure and coloration. If the 

 determination of those two specimens as A. oHentalis is correct, (and upon such good 

 authority, as Mr. Gurney, it ought to be), there can be no doubt that the two species 

 must be considered as identical. F. Stoliczlca.']
