ABSTRACT OF THE PROCEEDINGS 
OF THE 
ZOOLOGICAL SOCIETY OF LONDON.* 
May 19th, 1914. 
R. H. Burne, Hsq., M.A., Vice-President, in the Chair. 
The Minutes of the last Scientific Meeting were confirmed. 
The SzcrETARY submitted a Report on the Additions to the 
Society’s Menagerie during the month of April, 1914. 
Mrs. R. Hate THomas, F.Z.8., exhibited a number of skulls, 
head-skins, and photographs of hornless antelopes found by 
Mr. A. W. Haig in 1903 on the Dinder River, a tributary 
of the Blue Nile. There were two varieties, one larger than the 
other. On his return Mr. Haig submitted the skulls, skins, 
and photographs to the authorities at the British Museum, who, 
while admitting a difference in the formation of the skulls, 
declared there were no hornless antelopes and that all the 
specimens shown must have been females, treating the observa- 
tions of the travellers as of no moment. 
In ‘The Nile Tributaries of Abyssinia,’ first published in 
1867, Sir Samuel Baker tells us he met with and shot hornless 
antelopes on the Royan, a tributary of the Atbara, and we read 
farther on that the animal was already known to science and 
classified by Riippell. Thus it is shown that Baker’s and Haig’s 
hornless antelopes were found on the same watershed, in a 
geographical position not a hundred miles apart. 
Evidently our British Museum Catalogue of the Mammalia 
requires revision—it is sixty years out of date. 
Mr. D. M.S. Watson, M.Sc., F.Z.8., exhibited two specimens 
of Procolophon irigoniceps, a Cotylosaurian Reptile from South 
Africa, and drew attention to certain sexual differences in this 
Species.
