ORDER ARTIODACTYLA: EVEN-TOED UNGULATES

slowly, although Lonnberg (1906, p. 309) long ago had the main 

 facts from "Lieutenant Karl Eriksson, who delivered to Sir Harry 

 Johnston the first skull and skin of the Okapi. ..." 



He believed it to be distributed practically over the whole of the "equatorial 

 forest" of the Congo Free State. He showed me ... the approximate limits 

 of this area of distribution. If we begin at the River Ubangi in the west about 

 midway between Mobena and Jmese, from there the limit extends north-

east towards Businga at the River Likame or somewhat north of that place, 

 and then more east to the River Uele just before it joins the River Ubangi. 

 From that place and eastward the River Uele is the northern limit to a point 

 about midway between Amadi and Suruaugo. From there it turns south-east, 

 passing somewhat east of Mawambi, and continuing to a point a little west 

 of Karimi. Not much south of this, the most eastern point of the great 

 forest, the boundary-line turns westward again and crosses the great Congo 

 River at Ponthierville, and continues westward a little south of Tschuapa 

 River, but bends by-and-by a little north, so that it passes on the northern 

 side of Bolondo towards Coquilhatville. It is evident that this is only a 

 rough outline of the area of distribution of the Okapi, but it may hold good 

 in a general way. 



Lang (1918, p. 1602, map), despite his first-hand knowledge of 

 the Okapi, limits its range to the north of the equator, between 

 the rivers Ubangi and Uele on the north and the Congo on the south.
