Hab. West Africa from Angola to the Niger. 



Angola [Hamilton^ \ Brit. Mus.); Cazengo {Hamilton^)', 

 Viti, on the Congo [Dubois''); Loango Coast {Falkenstein^) ; 

 Gaboon (Verr.^); Camma and Muni Rivers {Du Chaillu^) ; 

 Ogowe River (Mar cAe", Ansell, Brit. Mus.); Niger {Baikie, 

 Brii. Mus.). 



As the specimen in the British Museum labelled Niger 

 [Baikie) undoubtedly belongs to this species, I should like 

 to have examined the specimens collected on that river by 

 Herr Hartert [vide supra) ; but I see no reason why both 

 the species should not occur there, as the locality where 

 the Bntish-Museum specimen was collected may be distant 

 from either Loko or Iddah,
