3. Two Riippell's Vultures (Gyps ruejujelli), receiyed in exchange 

 May 28tli, from the Zoological Gardens, Cairo. These fine birds, 

 which I saw at,Cairo when there last year (see P. Z. S. 1896, p. 400), 

 are said to have been obtained in the Western Desert of Egypt, 

 and are of much interest, as the species has not been previously- 

 noticed within the confines of Egypt proper. The authorities of 

 the Gizeh Gardens have kindly parted with them in our favour. 



Mr. Sclater exhibited the skin of a species of Cercopithecus which 

 had been received, living, by the Society on the 20th September 1895, 

 and had died in the Menagerie on the 23rd of April last, and a 

 water-colour drawing of the same animal by Sniit. Mr. Sclater 

 had been uncertain as to the correct determination of this specimen 

 (which had been obtained by Mr. John M. W. Pigott, when 

 Acting-Administrator for the I. B. E. A. Company at Mombasa, 

 East Africa, from a native who had caught it) in its lifetime, but now 

 believed that it must be referable to his Cevcojnlhecvs slccirsi (P. Z. 8. 

 1892, p. 580, pi. xl.), as shown by comparison with one of the 

 typical specimens. The presetit specimen, which was a female, 

 agreed in nearly every respect with the male presented by 

 Mr. F. Hintze, June 7, 1893 (see P.Z.S. 1893, p. 612), except in 

 being of smaller size, which was of course attributable to its sex, 

 and in having the bright rufous spot on the temples not so clearly 

 marked although plainly visible. The short erect hairs on the 

 front of the forehead were also more stained with rufous than in 

 the male specimen. 



Mr. Sclater remarked that this distinct species of GercopiiliecMs 

 had now been received from three different spots on the East Coast 

 of Africa — Chindi at the mouth of the Zambesi, Mozambique, and 

 British East Africa. 



Mr. Sclater exhibited a series of 12 water-colour drawings of 

 African Antelopes, taken partly from specimens in the Natural 

 History Museum and partly from examples living in the Society's 

 Gardens, executed by Mr. Edmund Caldwell, of 41 Clifton Gardens, 

 Maida Vale. 



A communication was read from Mr. Henry J. Elwes, E.Z.S., 

 and Mr. Edwards, containing a revision of the European and 

 Asiatic Butterflies of the Earaily Hesperiidse. The species treated 

 of in this paper were about 450 in number and were divided into 

 about 100 genera. 



This paper will be printed in the Society's ' Transactions.'
