examples of this species that have come under my personal 

 observation. 



The geographical distribution of A. rufonuc halts is, as I 

 have already observed, somewhat more limited than that of 

 A. clang a ; the most northerly locality for A. rufonuchalis 

 with which I am acquainted is the neighbourhood of Dantzic. 

 Like A. clanga it migrates southward in winter ; and from Von 

 Heuglin^s remark, quoted above^ it would appear to extend 

 its migrations as far to the south as that species. The Norwich 

 Museum possesses a specimen from Nubia and another from 

 Beyrout, the former being the most southern and the latter the 

 most eastern locality for this Eagle that I have personally veri- 

 fied ; the most westerly specimen that I have seen is one from 

 Switzerland, which is preserved in the Museum at Brussels. 



A. rufonuchalis is a decidedly less numerous species than 

 A. clanga, and has of late years become remarkably scarce, 

 much more so than ,was formerly the case. 



The nearly allied A. hastata appears, as stated by Mr. 

 Sharpe, to be limited to the Indian peninsula. 



The only remaining species of the genus Aquila \^A. wahl- 

 bergi, respecting which I have merely to mention that Mr. 

 Sharpens remark, " Hah. The whole of Africa," appears to me 

 to be too sweeping. The Norwich Museum possesses speci- 

 mens from Bissao, the White Nile, Abyssinia, and Nubia, 

 which are the only localities for this species with which I am 

 acquainted to the north of the Equator ; whilst to the south 

 of the Line, I am not aware that it has been obtained except 

 in the localities mentioned in Mr. Sharpe's edition of Mr. 

 Layard^s ' Birds of South Africa,'' at p. 36, viz. CaflFraria, 

 Kuruman, Mossamedes, and on the river Cunene, and also 

 in Damara Land, if, as I think most probable, it be an in- 

 dividual of this species, which is cited as from that country 

 under the title of " Aquila clanga, Pallas, No. 23," in the 

 Supplementary Catalogue of the Accipitres in the Leyden 

 Museum, 15^. 



* Since writing the above I have observed that the occurrence of a 

 second Damara example of this Eagle is recorded in the * Journal fiir 

 Ornithologie ' for 1876, at p. 308.
