These measurements agree aproximately with those of P. brucei somalica but 
are much smaller than those of P. brucei hindet WROUGHTON' described from the 
Kikuyu country. The present specimen is, however, probably related to the latter 
race because it shows exactly the same structure of the hind margin of the palate 
with >»a pair of protuberances» just as described by WROUGHTON (l. c. p. 108). As 
the type of P. brucei hindei also was an old female in stage VIII the measurements 
recorded in WROUGHTON'”s diagnose are directly comparable with those above. If 
such a comparison is made it will be found that the skull of my type specimen is 
9 mm. (more than 10 ”/o!) shorter and 8 mm. narrower than the corresponding mea- 
surements of P. b. hindei, which diserepancy appears to be too great for allowing 
identification. The smaller size of the skull, of the present race makes itself known 
in all other dimensions as well, but the narrowness of the nasals anteriorly (6 mm. 
against 8 in P. b. hinder) is especially striking as it amounts to one fourth of the 
measurement of the larger race. 
With regard to the colour this P. b. borana also differs in several respects from 
P. b. hinder. "The dorsal spot of the latter is for instance »cream-buff»>. 
The Hyrax described above appears to be smaller than other geographic races 
of Procavia brucei except somalica which, however, is geographically separated from 
this one by P. pumila and its subspecies P. b. rudolfi. The shortness of the descrip- 
tion of P. b. somalica prevents me from pointing out other differences, but as 
WROUGHTON undoubtedly had access to skulls of P. b. somalica as well, when he 
described P. b. hindei, and then pointed out the »curious palatal character» (as 
described above) of this latter animal this character probably represents one of the 
differences. 
In the year 1901 NEUMANN described a Hyrax of the Heterohyrax-group from 
»Kaffa, Gimirra and Bimescho> under the name Procavia thomasi.” As his description
