noid, and anole. Several cervical vertebrae, in a more or less frag- 
mentary condition, doubtless are referable to the same species, though 
probably not to the same individual. The animal is nearly allied to 
the existing B. caffer, but differs sufficiently in tooth-pattern to require 
its reference to a distinct species.

The type of this species is the mandible, with second and third 
molars, which is mentioned above. The jaw indicates an animal 
which is rather larger and more robust than B. caffer, judging from 
the specimens of the latter with which I have had an opportunity to 
compare it. 
The second and third lower molars are somewhat more elong-ate 
antero-posteriorly and narrower transversely than in the existing 
species, and the enamel wall bounding the valleys externally is more 
simple and less sinuous. The third molar (M. 3) is quite distinctly 
different from that of B. caffer ; the enamel loop, or pillar, between 
the two external crescents, which in the modern species is present in 
M. T and M. 2, but not in M. 3, is very prominently developed, while 
the fifth lobe, or heel, is much narrower and more compressed laterally, 
and contains no enamel lake. Probably in the unworn tooth a valley 
was present in the heel, but, if so, it must have been shallower than in 
B. caffer, and disappears at an earlier stage of wear. The heel is 
connected with the body of the tooth by a much narrower and more 
constricted neck, the cement-filled valley between the heel and the 
postero-external crescent being much wider and deeper. 
The horizontal ramus of the lower jaw is somewhat shallower 
dorso ventrally than in the modern species, but is very thick and solid. 
This species is named in honour of W. Anderson, Esq., Government 
Geologist of Natal.

Two different genera of antelopes are indicated by two different 
fragmentary specimens. These I have not been able to determine, 
partly because of the very unsatisfactory condition of the material, and
