November 19th, 1901. — The Secretary read a report on the additions 

 that had been made to the Society's Menagerie during the months of June, 

 July, August, September, and October 1901, and called special attention to 

 a large series of Indian birds (all new to the Collection) , which had been 

 presented by Mr. E. W. Harper, F.Z.S. — The Secretary also stated that 

 Col. B. Mahon, the Governor of Khordofan, had offered to present to the 

 Society a pair of young Giraffes, which were being kept at El-Obeid awai- 

 ting the Society's instructions. — A small collection of Mammals in spirit, 

 from Mount Ararat and the Caucasus, presented to the Society by M. Con- 

 stantin Satunin, C.M.Z.S., was laid upon the table. — The Secretary ex- 

 hibited some heads of Antelopes which had been obtained on the White Nile 

 by Sir William Garstin and Major Wilkinson. Amongst them was a 

 head of a male Gazella rvßcolUs, a scarce species, -r— Mr. R. Lydekker ex- 

 hibited, on behalf of the President, some photographs of the antlers of Père 

 David's Deer [Elaphurus davidianus), in illustration of the fact that the Stags 

 of this species shed and renew their antlers twice annually. — Prof. E. Ray 

 Lankester, F.R.S., read a memoir on the new African Mammal Okapia 

 Johnstoni. After an account of the history of the discovery of this remar- 

 kable animal by Sir Harry Johnston, Prof. Lankester gave a description 

 of its skull and skin, based upon the specimens forwarded to the British 

 Museum by the discoverer, and compared its structure with that of the 

 Giraffe and the extinct member of the same family, Helladotherium. The 

 nearest living ally of the Okapi was undoubtedly the Giraffe. — Mr. Old- 

 field Thomas read a paper on the five-horned Giraffe obtained by Sir Harry 

 Johnston near Mount Elgon. It was shown that, although the horns were 

 unusually developed, the animal could not be specifically separated from the 

 ordinary North-African Giraffe, Giraffa camelopardalis. This latter was be- 

 lieved to grade uniformly in the development of the horns and other charac- 

 ters into the South-African form, which would therefore be only a subspecies, 

 G. c. capensis. On the other hand, de Winton's G. c. reticulata (from 

 Somaliland) seemed to be sharply separated, and therefore to be worthy of 

 recognition as a distinct species, G. reticulata. With regard to the accessory 

 horns, it was shown that they, or rudiments of them, existed in all male 

 Giraffes, even in the southern subspecies. Mr. Thomas believed that these 

 rudimentary horns corresponded not only to the somewhat similar projections 

 found in Samotheriuni and the Okapi, but also to the large posterior horns of 

 Bramot/ieriunij and perhaps oi Sivotherium. If this were the case, it seemed 

 probable that they were the degenerate rudiments of horns which had been 

 large and functional in the Giraffe's ancestors. — Mr. J. Graham Kerr, F.Z.S.,
