EAST AFRICAN MAMMALS IN NATIONAL MUSEUM. 143 
HETEROHYRAX BRUCEI BORANA (Linnberg). 
1912. Procavia brucei borana LONNBERG, Ann. and Mag. Nat. Hist., ser. 8, vol. 9, 
p. 66. January. (North of Guaso Nyiro, not far east of Marsabit Road, 
British East Africa; type in R. Nat. Hist. Mus. Stockholm.) 
Specimens.—Four, as follows: 
British East Arrica: Mount Lololokwi, 4 (Heller). 
These specimens are almost indistinguishable in color from Hetero- 
hyraz brucei hindei, but are smaller, with much smaller skulls. The 
oldest specimens, however, are not older than stage VI. 
HETEROHYRAX BRUCEI HINDEI (Wroughton). 
1892. Procavia bruce: TRUE, Proc. U.S. Nat. Mus., vol. 15, p. 459. October 26. 
1910. Procavia brucei hindei WrouautTon, Ann. and Mag. Nat. Hist., ser. 8, vol. 5, 
p- 107. January. (Fort Hall, Kikuyu, British East Africa; type in 
British Museum.) 
1910. Procavia brucei maculata Osaoop, Field Mus., Zool. ser., vol. 10, No. 2, 
p. 6. February. (Lukenya Mountain [Ulukenia Hills], British East 
Africa; type in Field Museum, Chicago.) 
1910. Procavia brucei maculata Roosrvett, African Game Trails, Amer. ed., 
pp. 472, 484; London ed., pp. 484, 495. 
Specomens.—Sixteen, from the following localities: 
British East Arrica: Kapiti Plains, 2 (Loring); Kyulu [Ongo- 
lea] Mountains, 1 (Abbott); Ndi, 2 (Heller); Sir Alfred Pease’s Farm, 
Athi Plains, 3, including one large fetus in alcohol (Mearns); Ulukenia 
Hills, 8, including two large fetuses in alcohol (Loring). 
Mearns and Loring each collected a female containing two large 
embryos. 
HETEROHYRAX BRUCEI ALBIPES Hollister. 
Plate 56. 
1922. Heterohyrax brucei albipes HotusteEr, Proc. Biol. Soc. Washington, vol. 35, 
p. 135. October 17. (Telek River, Loita Plains, British East Africa; 
type in U. S. National Museum.) 
Specimens.—Kighteen, as follows: 
Britisu East Arrica: Telek Rivet, Loita Plains, 18, including six 
large fetuses in alcohol (Heller). 
This form is readily distinguished from the related Heterohyrax 
brucei hindei, in fresh pelage, by the white underparts and white 
inner half of hind feet. The skull is essentially as in hindei. 
Heller found two large embryos in each of three females collected 
in May. The breeding animals are in stage VIII.
