Mr. 11. B. Sharpe’s Catalogue of Accipitres. 223 
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 f The Ibis ' 
for 1873, p. 99, and those of Mr. Anderson in P. Z. S. 
1875, p. 21. 
The papers of MM. Alleon and Yian, 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 l'au- 
tomne" (Revue 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 1 The Ibis ’ for 1861, 
at p. 221, A. nipalensis is referred to under tbe name of A. ncevioides —a 
mistake for which. I am accountable, having wrongly identified two spe¬ 
cimens from Oudh which were presented by Col. Irby to the Norwich 
Museum.
