EAST AFRICAN MAMMALS IN NATIONAL MUSEUM. 141 
Although these specimens were collected not far from the type 
locality of Procavia mackinderi zelotes Osgood, which is between 
Naivasha and Kijabe, they seem clearly referable to Procavia jacksoni 
rather than to that form. Both specimens are females, and one of 
them is fully adult, in stage VIII as defined by Thomas.’

PROCAVIA JACKSONI DAZSMON Thomas. 
1910. Procavia demon THomas, Ann. and Mag. Nat. Hist., ser. 8, vol. 5, p. 199. 
February. (Elgonyi, 7,000 feet, Mount Elgon, British East Africa; type 
in British Museum.) 
Specimen.—One, as follows: 
British East Arrica: Kisumu, 1 (Heller). 
This specimen is, unfortunately, imperfect; the hair has slipped in 
places, parts of the head and legs have been destroyed by some 
animal, and the skull has been broken into small bits. It is clearly 
a true Procavia and, so far as can be determined, agrees very well 
with the description of demon. The hair is dark, long, and soft. 
Another form of the restricted genus Procavia, with which the Kisumu 
specimen should be compared, is Procavia matschiei Neumann,? 
described from Muansa, at the southern end of Victoria Nyanza, 
German East Africa. The following notes on the type of matschiet
