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,
