mammae are four. The skull resembles closely that of the 
West African royal antelope, Nesotragus , but differs by the 
presence of a maxillary-premaxillary sinus, by the larger 
anteorbital fossa, and the much broader nasal bones. The 
female equals the male in size. A single species is known, 
moschatus , which breaks up into several geographical races, 
and ranges from Mount Kenia and the Tana River south¬ 
ward through the coast drainage area to the Zambesi River 
and Zululand. It occurs also on Zanzibar Island. No fossil 
species are known.

ceived from the natives many specimens from the two small 
islands in the harbor where they were found living amid the 
dense growth of vines and bushes which clothe these small 
coral islands. The Zanzibar or typical form resembles the
