But not having been there I cannot affirm that other species 
do not occur. 
I believe the Buzzard has been attracted by and feeds on 
the domestic cats with which the island swarms. These cats 
having been introduced by former settlers, have increased 
and multiplied amazingly : they have taken to the hush, eaten 
up all the goats, and now live upon fish and young seals, and 
in their turn furnish food to the Buteo . 
VIII.— Notes on some European and Asiatic Eagles. 
By W. Edwin Brooks, C.E., Dinapore. 
My friend the Bey. Dr. Tristam has lent me an African ex¬ 
ample of Aquila ncevioides , Cuv., in characteristic tawny plu¬ 
mage, upon which I wish to offer a few remarks. 
1. It is totally distinct from the Indian species which has 
hitherto borne that name. The references to this Indian 
species in f The Ibis' are:—July 1868, pp. 351, 352; April 
1870, p. 290; July 1870, p. 423; April 1871, p. 245; Octo- 
her 1871, p. 479; and October 1872, pp. 472,473. It is also 
described in Mr. Hume's f Bough Notes,' p. 168, as the young 
of Aquila n&via. 
2. Aquila ncevioides is not a round-nostrilled Marsh-Eagle, 
like the Indian bird and like the other two Marsh-Eagles, 
A. ncevia and A. hastata , hut is a long-nostrHied Eagle, with 
vertical nostrils, like A. vindhiana } A . hifasciata , and A. 
mogilnik. 
3. Its tail is a greyish barred one, like that of A. vind- 
hiana ; and altogether its affinities are with this last-named 
species; but its mode of coloration is distinct, and very much 
more handsome in every way. In the tawny stage it has even 
a more distinct black eyebrow than the Indian species called
