bequest to them, and became the foundation of a stock which flourished for 
many years in the Regent’s Park Gardens. Young ones were bred of this 
pair or of their descendants in 1852, 1853, 1860, and 1864. Fresh examples 
of the Leucoryx were obtained by the Society in 1870 and 1880, and in 1881 
a fine female was brought home and presented to the Menagerie by the late 
Mr. John M. Cook, F.Z.S. 
This Antelope has not done so well in the Regent’s Park of late years, but - 
there is still one example of it living in the Menagerie, obtained last year, 
and it is hoped that a breeding pair may soon be re-established. An excel- 
lent figure of the adults of both sexes of the Leucoryx Antelope, drawn by 
Wolf from the Zoological Society’s specimens, was published in the first 
volume of Wolf and Sclater’s ‘ Zoological Sketches.’ In the second volume 
of the same work a young one, likewise drawn by the same skilful artist, 
is represented on plate xix. The calf in question was born in 1851, and was 
about six months old when Mr. Wolf's water-colour drawing (from which 
fig. 93, p. 49, has been taken) was prepared. 
Lord Derby’s stock of the Leucoryx is said to have been received from 
Nubia, while others in the Zoological Society's Gardens came from Senegal. 
We have not been able to recognize any difference between animals from 
these two countries, although they have been separated as distinct local forms 
(nubica and senegalensis) by Wagner, and more recently by Herr Matschie 
as different species. 
There are at present no complete specimens of this Antelope in the British 
Museum, and skins of it fit for mounting both from Dongola and from Senegal 
are much required, in order that a strict comparison of examples from these 
widely distant localities may be made. ‘The series now in the National 
Collection consists only of a mounted skeleton formerly in the Zoological 
Society’s Museum, a skin and skull of a young one from Sennaar, and some 
skulls and horns. 
Our Plate of this Antelope (Plate LX XXI.), which represents both sexes, 
was drawn on stone by Mr. Smit from a sketch prepared by Mr. Wolf, and 
probably represents the same animals as the plate in ‘ Zoological Sketches’ 
above referred to.
