DUIKERS AND SMALL ANTELOPES 565 



with short horns which rise vertically above the orbits and 

 are without rings. False hoofs are lacking in this genus, but 

 are present in the closely allied grysbok of South Africa. 

 The skull shows considerable peculiarity of structure in the 

 small size of the anteorbital fossa, which is a small, deep pit 

 much less in size than in the other genera of the subfamily. 

 The sinus between the nasal bones and the anteorbital pit is 

 of very large size and quite equal in area to the pit. The 

 snout is of moderate length and has very broad premaxillary 

 bones bordering the nasal aperture. The sexes are alike in 

 color and equal in size. The newly born young are in no 

 way different in color from the adults, but their pelage is 

 somewhat more woolly in texture. 



The steinbok reaches in British East Africa its most 

 northern limit. From the highlands near the base of Kenia 

 it ranges southward along the East Coast to the immediate 

 vicinity of the Cape. It, however, does not occur west of 

 the Victoria Nyanza or Tanganyika drainage. The genus 

 consists of a single species, campestrisy with two or more 

 geographical races, the most northern of which reaches 

 British East Africa. No fossil species are known.

Range. — From German East Africa northward through- 

 out the highlands of the Rift Valley and coast drainage area 

 to the northern slopes of Kenia and Elgon, in British East 

 Africa; east as far as the coast lowlands and west to the 

 shores of the Victoria Nyanza. 



The Masai steinbok was named by Doctor Matschie for 

 Herr Oscar Neumann, who was one of the pioneer natural- 

 ists of East Africa. He collected the type specimen at 

 Mount Gurui in central German East Africa. A specimen 

 collected south of the Victoria Nyanza by Speke and Grant 

 forms the first record of the species in equatorial Africa. 

 Jackson, Willoughby, and other sportsmen who visited Kili- 

 manjaro in the early days found the steinbok in abundance
