xxiv INTRODUCTION 



The Ruwenzori range has now been investigated 

 as completely as is at present possible ; unfortunately, 

 the western heights, which lie within the Congo 

 territory, had to be abandoned before they had been 

 properly explored, owing to the hostility of the 

 natives. 



The collections formed are among the finest that 

 have ever been sent to the British Museum, both as 

 regards the number of species and the perfect con- 

 dition in which they have reached this country; and, 

 so far as the birds are concerned, they, no doubt, 

 contain the great majority of the species which 

 occur in Ruwenzori. 



At present it is only possible to give some slight 

 idea of what has been done, and the following is a 

 list of the specimens which have been received : 



404 Mammalia (twenty-three 33 Orthoptera.
