These measurements prove that this little Hyrax is not far from fullgrown 
when it reaches stage VI according to THomMAs’ terminology.’ 
In the fully adult specimens the hind margin of the palate is somewhat raised 
and swollen along either side, and this ridge ends in a kind of protuberance on either 
side of the central process fully separated from the same by a notch. This condition 
reminds about that described by WrovuaGuton on the skull of the much larger Pro- 
cavia brucei hindei.? (Concerning P. b. borana, conf. above.) The nasals are short 
and broad, evenly tapering in front, not suddenly constricted and then with parallel 
margins as in the other Hyrax which also was found north of Guaso Nyiri but above 
Chanler Falls viz. Procavia brucei borana, which has been described above. 
The fact that two small representatives of the Heterohyrax group are found 
so near each other without being separated by any physical geographical obstacle is 
of interest, the more so as analogous cases were found among the Baboons (conf. 
above) and Dik-diks (conf. below).

An adult male (stage VIII according to THomAs’ terminology) was shot in the 
forest near Escarpment station. The colour of this specimen agrees exactly with the 
description of the type except that the belly is not »deep buffy» but buffish white. 
The lower side of the neck is more buffy. The head is perhaps also darker than 
that of the type specimen as the black in the grizzled parts is dominating over the 
whitish.
