The two described forms of the gerenuk seem poorly differentiated, 
but our material is hardly adequate for a decision as to the validity 
of the northern race. The specimens are listed under their respective 
names on purely geographical grounds.

Genus ORYX Blainville. 
1816. Oryx BLaINvVILLE, Bull. Sci. Soc. Philom., p. 75. May. (Oryx gazella.)? 
A subspecies of the oryx, intermediate between Oryx beisa annectens 
and O. b. callotis, has recently been described by Lord Rothschild. 
No definite type locality is given, but the new race is said to inhabit 
southern British East Africa in the “country between the ranges of 
O. g. callotis and O. g. annectens.”’ This might mean any one of 
three widely separated regions—near the coast south of the mouth 
of the Tana River, the country about Makindu on the Uganda Rail- 
way, or, still farther to the westward, the Rift Valley south of Mount 
Suswa. No specimens representing the race are included in ‘the 
collections of the National Museum. Rothschild treats all the forms
