arrange, and before it had reached its destination and commenced work a number of 

 the birds peculiar to the region had already been procured and sent to the British 

 Museum by Mr. F. J. Jackson, C.B., whose nephew, Mr. Geoffrey Archer, paid a short 

 visit to the north-eastern slopes of Ruwenzori in February 1902. 



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 condition 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 on Ruwenzori. 



Some slight idea of what has been done may be gathered from the following list of 

 the specimens which have been received : — 



404 Mammalia. 

 2470 Aves. 

 135 Reptilia and Amphibia. 

 31 Pisces. 

 12 Crustacea. 

 100 Arachnida. 

 1015 Coleoptera. 

 33 Orthoptera. 



25 Neuroptera. 

 47 Hymenoptera. 

 1372 Lepidoptera. 

 130 Hemiptera. 

 23 Homoptera. 

 55 Diptera *. 

 38 Mollusca. 

 66 Vermes. 



A large number of the species were new to science. 



Lastly, a very fine collection of dried plants (including many new species) was made. 

 Numerous growing plants and seeds were also sent home, and are now being cultivated at 

 the Royal Botanic Gardens at Edinburgh, under the care o( Professor I. Bayley Balfour. 



The close affinity between the Highland Fauna of Ruwenzori and that of the 

 Cameroon is a very striking feature of the collection as a whole ; and now that the 

 various groups have been thoroughly worked out, it is evident that a very valuable 

 addition has been made to our knowledge of the Fauna and Flora of Tropical Africa. 



It is in accordance with the traditions of the Zoological Society that the heavy cost 



of publishing the zoological results of the Expedition should have been assumed by 



that body.
