The route and brief description of the travel. 



The expedition, the results of which form Ihe subject of 

 this l>ook, was performed by us in the summer of i!M4 and 

 occupied about 6 months (from the o-th April till the 

 30-th September). The chief purpose of this travel was col-

 as we could not expect to attain good results in this direc- 

 tion owing to the comparatively modest means that were at 

 our disposal. Besides this, systematic collections seemed less 

 important to us, as they formed the only object of most expe-

 a tendency, our collections gave material for a series of fau- 

 nistic works as well, as may be seen from the contents of 

 this volume. 



Our route was as follows: having boarded the steamer at 

 Marseilles we reached Mombasa, the chief port of the British 

 East Africa Protectorate, having passed via Naples, Port Said, 

 Suez and Aden. Mombasa is the starting point of the Uganda 

 Railway joining the shores of the Indian ocean with the 

 Eastern shore of lake Victoria Nyanza. From here we set 

 forward to the capital of the country, Nairobi, situated 

 along the railway line between Mombasa and lake Victoria 

 Nyanza. At Nairobi we worked out our route of travel further 

 with the most hearty assistance of M-r Woodhouse, performing 

 the duties of Game Warden. During our weekly stay at Nai-
