time believed to be correct^ but am now convinced is erro- 

 neous^ as I have already explained in 'The Ibis' for 1873, 

 p. 422^. 



The specimen of A. nipalensis described by Mr. Sharpe 

 as an adult male is not, in my opinion, completely adult ; the 

 fully adult stage is, I believe, that which is succinctly de- 

 scribed by Mr. Anderson (P. Z. S. 1872, p. 621) as of a 

 uniform brown, with the addition of a fulvous-coloured nuchal 

 patch f. 



Mr. Sharpe, in his description of this species, does not 

 refer to the peculiar transverse markings, extending from the 

 sternum to the vent, which are occasionally to be observed in 

 Indian specimens of this Eagle whilst in a state of change 

 from the first immature dress to the fully adult plumage : for 

 a fuller description of this stage, which I have not yet met 

 with in European examples, see my remarks in ' The Ibis ' 

 for 1873, p. 99, and those of Mr. Anderson in P. Z. S. 

 1875, p. 21. 



The papers of MM. Alleon and Vian, to which I have 

 already referred, contain many interesting particulars re- 

 specting the migration of this and other Raptorial birds, as 

 observed in the neighbourhood of the Bosphorus. Space will 

 not allow me to quote more than the following summary of 

 the observations of those gentlemen relating to the present 

 species : — " C^est lui qui ouvre, sur le Bosphore, les migrations 

 du printemps ; il parait, des les premiers jours de Mars, par 

 bandes considerables, exclusivement formees d'oiseaux de cette 



espece, mais le nombre en est beaucoup moindre a I'au- 



tomne''' (Bevue et Mag. de Zool. for 1869, p. 313; conf. also 

 Messrs. Buckley and Elwes in 'The Ibis' for 1870, p. 68). 



Mr. Dresser, referring to these migrations in his article on 

 this species in ' The Birds of Europe,' makes the following 



* In Col. Irby's paper on the birds of Oudh, in ' The Ibis ' for 1861, 

 at p. 221, A. nipalensis is referred to under the name of A. ncevioides — ^a 

 mistake for which I am accountable, having wrongly identified two spe- 

 cimens from Oudh which were presented by Col. L'by to the Norwich 

 Museum.
