FOURTH SUPPLEMENTARY LIST OF MAMMALS IN THE 
COLLECTION OF THE TRANSVAAL MUSEUM. 
By Austin Roberts. 
In previous papers * I have given lists of specimens in the mammal collection 
of the Transvaal Museum, and I propose now to deal with those more 
recently acquired. Several gentlemen have kindly presented specimens, 
other specimens have been purchased, and the rest have been collected 
by members of the staff of the Museum from time to time. Amongst the 
donations may be mentioned two beautiful specimens of an apparently 
new Malacothrix, kindly presented by Harold A. Fry, Esq., and taken at 
Klipriviersoog, Krugersdorp District. Dr. P. G. de Villiers has also 
presented some good specimens of Cynictis, Erinaceus, and Proteles, 
collected at Hatfield, Pretoria suburbs. Mr. W. Powell has been employed 
in collecting specimens in the wilds of Rustenburg District, and has secured 
a number of specimens that are either new to science or new records 
showing greater extension in the distribution of certain species. Mr. Noome, 
of the staff, has secured good series of larger animals in Portuguese Gazaland. 
Mr. Van Dam, in addition to his good work in collecting lower vertebrates 
and Arachnids , has displayed a commendable zeal in securing small 
mammals, the most notable of his captures being specimens of Helogale 
parvula and a new Georychus , both from Leydsdorp in the Lydenburg 
District. Messrs. J. Breyer and A. A. Adendorff have also assisted in 
securing specimens from time to time. I have again to thank Mr. A. L. 
Hall for kindly taking me with him on two occasions during his geological 
survey of the region south of Barberton and on the western border of 
Swaziland, when good series of small mammals were secured. 
So much material has been acquired that I have thought it advisable 
to review the known species of South African Georychi, and in doing so 
have had the assistance of the collections in the Albany and South African 
Museums, for which I have to thank the respective Directors, Messrs. J. 
Hewitt and Peringuey. The Georychi of the Cape Province prove, however, 
to be still too puzzling to satisfy me that there are not more species found 
there than has so far been admitted. The Director, Dr. Breyer, has therefore 
consented to allow me to proceed to the Cape Province to study these 
animals as soon as the climatic conditions are suitable, and I hope therefore 
at a later date to be able to report thereon. In the meantime I shall 
confine my attention to the description of some new species in the genus. 
Papio porcarius (Bodd.). 
1 A, Mooivlei, Rustenburg District (Powell). 
In this specimen, as well as another $ from the same place, which 
had to be destroyed, the hands are black and the feet partly black.
