1 $ 31. 5. Mount Elgon 6.800 feet above sea-level. 



A single individual stayed for several days around our 

 camp on Elgon and sometimes came right up to the tent to 

 snatch away some animal remains lying there. 



It is very likely that this specimen, which had strayed as far 

 as Elgon, is in all probability a casual visitor from the country to 

 the north, around the Nile and other waters. Comparing the 

 measurement figures of this bird with those of the Mombasa 

 specimens (following bird) we find that, with the exception of 

 the tarsus, they are all higher. Further, it is light rusty- brown 

 all over the belly, while M. migrans parasitus, on the other 

 hand, is generally very dark-brown-alraost dark grey-brown. 



Even the colour tone of the head and back is light brown, 

 whereas that of the sub-species is dark grey-brown. 



Hartert says also (Bull. Brit. Orn. Club, 1913, p. 89— 90j 

 that "the true M. aegyptius ranged southwards, sometimes per- 

 haps in in winter only, to South Arabia and Somaliland. A bird 

 from Mount Kenia appeared to be intermediate, like some of 

 those from Somaliland." 



Tot. length, wing, bill from cere, tarsus, tail, 



575 mm. 452 mm. 26 mm. 53 mm. 280 mm. 



Irides cinnamon-brown, bill and cere yellow, legs citron- 

 yellow. 



With regard to the coloration of the bill, Nicoll has shown 

 that it varies considerably with age and season and he considers 

 "that perfectly conditioned birds have the yellow bill and young 

 birds assume the yellow bill at their first moult."
