Mr. J. H. Gurney's Notes on 
the mantle and under surface of A. rap ax in immature plu¬ 
mage, and which was well described by the late Sir A. Smith 
in the following sentence :—“ The young are of tawny chest¬ 
nut colour, and without the brown variations observed in 
the old"*. 
Aquila rapax appears to be the commonest Eagle in the 
colony of the Cape of Good Hope; and thence it has been 
ascertained to extend its range in a north-easterly direc¬ 
tion to the Republic of Transvaal, and in a north-westerly to 
the Mossamedes district in Benguelaf. 
On the western side of the African continent, north of the 
equator, we meet with A. rapax at Senegal; and the British 
Museum possesses a typical example in immature plumage 
from that locality. Other specimens from Senegal, which are 
preserved in the Museum at Paris, are said to he identical 
with South-African examples J; but Professor Schlegel, in 
the f Museum des Pays-Bas/ vol. i. Aquilce , p. 5, has the fol¬ 
lowing footnote :—“ Les individus originates du Senegal, que 
j'ai pu examiner, offrent en general des teintes un peu plus 
ternes que ceux de l'Afrique australe;" the same author, 
however, in his supplementary volume, Accipitres , p. 116, 
mentions a specimen of this Eagle, acquired by the Leyden 
Museum subsequently to the issue of his first volume, as 
“ femelle aux teintes fauves, Senegal." 
Proceeding northwards, it would appear that A. rapax oc¬ 
curs in the neighbourhood of Mogador, as I understand from 
Lord Lilford that the two specimens figured by him in f The 
Ibis 3 for 1865 were both said to have come thence. 
What range A. rapax may have in those parts of North 
Africa which border on the Mediterranean I am unable to 
say, having only examined two specimens of Eagles of this 
group from there, both of which appear to me to be more 
nearly allied to A, albicans than to A. rapax , on which ac¬ 
count I defer their consideration for the present.
