Cameroon Mountain is the type locality of this species, 

 which is also found in Fernando Po. 



It is hard to understand how Alexander referred the 

 specimens which he obtained in Fernando Po to 0. elgun- 

 ensis Sharpe, from British East Africa ! Apart from the 

 astonishing distribution which a jump from Mt. Elgon to 

 the Gulf of Guinea would entail, the island bird has a 

 much narrower and longer bill than the East African form. 

 The quite young bird, as shown by examples in the British 

 Museum, has a grey head and throat. 



[Not common; found about Buea and in the forest below 

 Miissarka. — B. A.] 



The following is a list of species known to have been 

 obtained on, or around the foot of, Cameroon Mountain. 

 The limit of the spurs of Cameroon Mt. extend from Victoria 

 to Bibundi and north to South Barombi Lake (Richards), 

 as has been indicated by a line in the Map, PI. VI. The 

 majority of species are given on the authority of Dr. 

 Eeichenow t, who is responsible for the localities mentioned, 

 except where a species is marked with an asterisk. 

 Species obtained by Alexander are so marked, together with 

 the locality given on his authority.
