These measurements prove that this little Hyrax is not far from fullgrown 

 when it reaches stage VI according to Thomas' terminology.^ 



In the fully adult specimens the hind margin of the palate is somewhat raised 

 and swollen alon^ 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 Wroughton on the skull of the much larger Pro- 

 cavia brucei hindeiJ (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 Palls 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 huffish 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.
