Show 1868.] MR. SCLATER ON FALCO ELEONORJE. 567 to be specifically distinct from the common Macacus rhesus, having a pale flesh-coloured face, and longer, smaller, and much less densely furred tail. 3. Two White American Cranes (Grus americana), purchased of the Zoological Society of Antwerp, and received November 12th and 19th. These birds were in the brown immature plumage, in which stage they were not unlike the young of Grus montignesia, figured in the Society's 'Proceedings' for 1861, p. 369. Mr. Sclater remarked that the acquisition of this species raised the number of representatives of the family Gruidce now or lately in the Society's Gardens to twelve in number, viz.:- I. Grus montignesia. 7. Grus canadensis. 2. americana. 8. carunculata. 3. cinerea. 9. Tetrapteryx paradiseus. 4. leucogeranus. 10. Balearica pavonina. 5. antigone. 11. regulorum. 6. australis. 12. Anthropoides virgo. The only two well-determined species wanted to complete the series were G. vipio and G. monachus of Japan, of which the Society had never yet succeeded in acquiring specimens. Mr. Sclater also remarked on the great difference in size between the two specimens of G. canadensis lately living in the Gardens, and stated his opinion that it was probably on a small specimen of this bird that Mr. Cassin had established his Grus frater cuius. Mr. Sclater also called the attention of the Meeting to the two Eleonora Falcons (Falco eleonoree) presented to the Society's collection by Capt. Thomas Waite on the 7th of October, and stated that, in reply to inquiries, Capt. Waite had favoured him with the following account of the exact locality in which these birds were procured : - " I found these Falcons on the Island of Mogador. It is a very curious place; and there are properly two islands and several detached rocks, but the whole extent is only about one-fourth by three-fourths of a mile. In height it does not exceed 100 feet; and about half of it is very steep and craggy, and the rocks curiously honeycombed and forming natural holes and ledges, in which thousands of birds build and sleep-some sea-birds and Martins, but principally Pigeons. The favourite place with the birds is what we call the little island, which is nearly round, about 90 feet high and about one-fourth of a mile in diameter. When you get to the top you find it a mere shell, the centre being an immense basin, with perpendicular sides, a large archway at the north and south ends, through which the sea flows, and at high water you can get a boat inside. There is no water on the island, and the Pigeons go to the mainland in the daytime; but I do not think the Falcons ever leave it." The following papers were read :- |
