INTRODUCTION. 

 Of the collections formed by the Members of the Ruwenzori Expedition probably 

 none is so complete as that of the Birds. This is partly due to the fact that as four of 

 the collectors were specially interested in Ornithology, every effort was made to obtain 

 examples of all the species to be met with on the range. It is thus pretty certain that 

 of the different kinds of birds to be found on Ruwenzori very few are not represented 

 in the present collection. 



The only known exceptions are a small Swift, seen at about 10,000 ft. ; an Owl ; 

 possibly a Pigeon, which is described as a " Black Dove," and may have been the 

 young of Ilaflopelia jacksoni ; and a large species of Francolin. The latter frequented 

 the thickest parts of the forest and, though its cry might constantly be heard, 

 its skulking habits baffled all the efforts made to procure specimens. Mr. Carruthers 

 actually succeeded in shooting one, but the bird being only winged instantly disappeared 

 among the dense jungle. 



In addition to these there are also two species, Cryptospiza shelleyi (of which only 

 the type-specimen is known) and Necfarinia melanogastra, which were not met 

 with by the present Expedition, but which were procured by Mr. Geoffrey Archer 

 on Ruwenzori, though the exact locality was not recorded. Euprinoides nigrescens, 

 which was also said to have been procured on Ruwenzori by the same collector 

 {cf. Jackson, ' Ibis,' 1906, p. 547), was no doubt obtained in Ankoli, as is shown by 

 the date, April the 8th, 1902 (see Archer, Itinerary, p. 506). 



It is, of course, more than likely that, in addition to those mentioned, other species 

 may have been overlooked and that locally distributed forms may occur in valleys which 

 were not visited by the Expedition. As an instance of this I may mention that of a 

 very handsome Sun-bird {Nectarinia purpureiventris) only one example was procured 

 by Mr. Gerald Legge during the four months spent in the Mubuku Valley ; while
