 appears in tlie Nile Province below an aUitude of 3,000 feet, in the

 shores of Lake Albert Edward.

that country. This Central African region presupposes an average altitude 

 of 3,500 feet in the equatorial regions of Uganda. It is characterised by 

 abundant vegetation, a great deal of grass, many species of herbaceous plants,

 interior parts of Kavirondo, Busoga, I'ganda, Unyoro, Toro, and Ankole, 

 between 4,000 and 6,000 feet in altitude.
