Heller, Mearns, Loring, Cuninghame); Tana River, 3 skulls (Hep- 
burn, Perie, Witherill); Taveta, 4, including one fetus and one odd 
skull (Abbott); Telek River, Loita Plains, 1 (Rainey). 
Six of the above listed specimens include the skeletons. 
Not having seen specimens of typical Diceros bicornis of South 
Africa in this connection, I am unable to add any information regard- 
ing the validity of the East African subspecies of the black rhinoceros. 
Some recent authors have refused to recognize holmwoodi as a distinct 
race, but it would seem almost unbelievable that the animals of 
British East Africa and Uganda could not be distinguished by some 
character from those of South Africa. 
DICEROS BICORNIS SOMALIENSIS (Potocki). 
1900. Rhinoceros bicornis somaliensis PotocK1, Sport in Somaliland, p. 82. (Oga- 
den, Abyssinia. ) 
1914. Diceros bicornis somaliensis RoosEvELT AND Hewier, Life-Hist. African 
Game Anim., vol. 2, p. 656. 
Specimens.—Seven, from the following localities: 
British East Arrica: Archer’s Post, 1 skull (Rainey); Isiola 
River, 2, including one fetus (Rainey); Lakiundu River, 3, including 
one fetus and one odd skull (Rainey); Longaya Water, Marsabit 
Road, 1 skull (Rainey). 
Not all of these specimens from the Northern Guaso Nyiro region 
are typical of somaliensis, but the series as a whole seems best 
referred to that race rather than to the subspecies holmwoodi of the 
region from Mount Kenia southward in British and German East 
Africa. The name Rhinoceros cucullatus Wagner, 1835,' given to an 
animal of unknown origin and doubtfully attributed to Abyssinia, 
seems quite unidentifiable but perhaps refers to an Asiatic species. 
The type-specimen is said to be in the museum at Munich and if so 
its status might be determined.? Rhinoceros brucw Lesson,’ listed 
by Schwarz‘ as a valid name based on Blainville’s Rhinocéros d’ Abis- 
sinie,®> with type-locality at Tscherkin, between the Bahr Salaam and 
the Atbara Rivers, northwestern Abyssinia, is a nomen nudum. 
Genus CERATOTHERIUM Gray. 
1867. Ceratotherium Gray, Proc. Zool. Soc. London, p. 1027. (C. simum.) 
The splendid series of specimens of the white, or square-lipped, 
rhinoceros, collected by Col. Theodore Roosevelt and party in the 
Lado Enclave, gives the Museum a good representation of this rare 
mammal.
