Two, if not three, species of giraffes are known, 

 all natives of Africa, and recently Sir Harry John- 

 ston has described a species with five horns living 

 in Uganda. The same naturalist brought home 

 from Africa the skin and skull of a giraffe-like 

 animal called by the natives '^ Okapi,^^ which is 

 striped, not dappled. This skin has been mounted,

 History. Later Sir Harry Johnston contributed 

 from the Semliki forest the complete skin of a 

 female animal of the same kind, which has received 

 the scientific name of Okapia Johnstoni. More
