and made the following remarks : — “ The name Aquila ful- 
vescens has hitherto been bestowed on Indian specimens, and 
this form has, up to the present time, been admitted by British 
ornithologists to be a well-marked and distinct species. The 
late Eugen von Homeyer described a European example 
under the name of Aquila boecki, and since then, including 
the one exhibited to-night, three more examples have been 
recorded from Europe, Mr. Hartert, Dr. Otto Beiser (m 
lilt.), and several other naturalists have more than once drawn 
attention to the exactly similar proportions and external 
characters existing between Aquila maculata and Aquila 
fulvescens, the only difference being in the colour of the 
plumage, and they have suggested that A. boecki might be a 
more or less constant aberration of Aquila maculata. 
“ I think that the young bird exhibited will convince most 
ornithologists, as it has myself, that Aquila fulvescens is 
really a parallel ^aberration’ to the light forms of the Common 
Buzzard, Buteo buteo, and that it is not a good species. 
This young bird has the upper and under tail-coverts, as 
well as the feathers of the leg and thigh, of the same pale 
buff’ colour, and in these markings it resembles the adult 
Aquila fulvescens ; while the rest of its plumage is identical 
with typical young of Aquila maculata. A further proof is 
that a few examples of the Indian Little Spotted Eagle 
(A. hastata) show a tendency to have large buff areas of 
plumage. I therefore consider that there are only three 
species of Spotted Eagles with round nostrils, viz. : 1. Aquila 
maculata, 2. Aquila pomurina, 3. Aquila hastata. It follow's, 
therefore, that Aquila fulvescens must be sunk as a species 
and must stand as Aquila maculata, aberr. fulvescens.” 
Mr. Rothschild exhibited a series of birds from the island 
of S. Thomd, in the Bight of Benin, and made remarks on 
some of the species which were peculiar to the island. 
He also called the attention of the meeting to some re- 
markable specimens of Phalacrocorax chalconotus, illustrating
