1900. Procavia mackindert Tuomas, Proc. Zool. Soc. London, p. 176. (Teleki 
Valley, 13,000 feet, Mount Kenia, British East Africa; type in British 
Museum.) 
1910. Procavia mackindert RoosEvett, African Game Trails, Amer. ed., pp. 472, 
483; London ed., pp. 484, 494. 
Specumens.—Twenty-two, as follows: 
BritisH Hast Arrica: West side of Mount Kenia from 13,000 to 
15,500 feet altitude, 22, including one odd skull (Mearns, Loring). 
This series includes only seven adult animals, and the majority of 
the specimens are quite young. 
Mr. Loring, who collected many of our specimens on Mount Kenia, 
has the following interesting account of the animal in Appendix C of 
Colonel Roosevelt’s African Game Trails: 
On Mount Kenia at altitudes between 12,000 and 15,000 feet we found these animals 
common wherever protective rocks occurred. Under the shelving rocks were great 
heaps of their droppings, and in the places where for centuries they had sunned them- 
selves the stone was stained and worn smooth. At all times of the day, but more 
frequently after the sun had risen, they could be seen singly, in pairs, and in families, 
perched on the peaks. At our highest camp (14,700 feet), where on the 22d of Sep- 
tember more than half an inch of ice formed in buckets of water outside the tent, 
they were often heard. They emit a variety of chatters, whistles, and cat-like squalls 
that can not be described in print, and we found them very noisy. Whenever they 
saw any one approaching they always sounded some note of alarm, and frequently 
continued to harangue the intruder until he had approached so close that they took 
fright and disappeared in the rocks or until he had passed. All along the base of 
cliffs and leading from one mass of rocks to another they made well-worn trails through 
the grass. At this time of the year many young ones about one-third grown were 
seen and taken. 
PROCAVIA MACKINDERI ZELOTES Osgood. 
1910. Procavia mackinderi zelotes Oscoon, Field Mus. Nat. Hist., Zool. ser., vol. 
10, No. 2, p. 5. February. (Between Naivasha and Kijabe, British 
East Africa; type in Field Mus. Nat. Hist., Chicago.) 
Spectmens.—Seven, from localities as follows: 
British Hast Arrica: Loita Plains, 1 (Heller); Mount Gargues, 
1 (Heller); Mount Lololokwi, 2 (Heller); Rumathe River, 1 (Heller) ; 
Suswa Plains, 2 (Heller). 
These specimens of the large-toothed, typical Procavia from points 
in British East Africa from the mountains north of the Northern 
Guaso Nyiro River south to the Loita, as listed above, all agree in 
general appearance and are readily distinguished from Procavia 
jacksoni by the cranial characters alone. 
PROCAVIA JACKSONI JACKSONI Thomas. 
1900. Procavia jacksoni THomas, Proc. Zool. Soc. London, p. 176. (Ravine 
Station, British East Africa; type in British Museum.) 
Specumens.—Two, as follows: 
Britiso East Arrica: Naivasha Station, 2 (Loring).
