230 Mr. J. H. Gurnets Notes on 
their striated plumage in confinement, and to which I have 
already alluded. 
Before leaving the subject of the Antwerp Eagle, I may 
mention that some slight changes which occurred in its plu¬ 
mage between 1868 and 1874 are detailed by Professor Yan- 
den-Nest in a letter which is printed at page 91 of the first 
volume of the second edition of Dr. Breeds work. 
As regards the more eastern range of A. rapax, I have no 
information beyond the fact of its inhabiting Palestine and 
breeding there, which is recorded by Canon Tristram in f The 
Ibis J for 1865, p. 252 ; I have never had the opportunity of 
personally examining an Asiatic specimen. 
I will now refer to such facts as I have been able to collect 
relative to the Eagle inhabiting Abyssinia and the adjacent 
countries, for which Buppell proposed the specific name of 
albicans , though he subsequently abandoned this for the older 
appellation of rapax *, under which latter designation it is 
also referred to by two eminent subsequent explorers of Abys¬ 
sinia, Blanford and Yon Heuglin. 
These Abyssinian Eagles do not differ from the typical A. 
rapax of South Africa in form or measurements f; and the 
question to be considered has therefore reference to colora¬ 
tion and markings only. On the former of these heads Mr. 
Blanford observes, “the plumage varies from umber-brown 
to rufous, the latter colour prevailing in adult birds, especially 
on the head and upper part of the back ; old birds are whitish 
(A. albicans, Hupp.).'’'’ 
With regard to the last of these observations I may men¬ 
tion that the specimens which I have examined lead me to 
believe that the colour, or rather lack of colour, described by 
Mr. Blanford as “ whitish,^ is less due to the age of the bird 
than to the age of the feathers, which frequently become much 
* Vide ‘Neue Wirbelthiere,’ p. 34, and ‘ Systematische Uebersicht,’ 
p. 10. 
t Dr. A. Brehm, who, in his interesting Notes on the Birds of the Bogos 
Country, recognizes A. albicans as distinct from A. rapax , considers the 
former to he the larger bird of the two (vide 1 Naumannia,’ 1855, p. 15); 
but I do not find that such is the case on an average of the specimens 
which I have examined.
