delphia, 1857, p. 10, Leconte gives descriptions of several new mam 

 mais from « Western Africa ». Hence this vague term has since been 

 given by authors as the type locality of thèse species. But Leconte 

 says also that thèse mammals « were among a large collection of 

 birds sent from Africa by M. du Chaillu ». Now this collection of 

 birds is referred to in the same journal on pp. 1 and 33, where we 

 learn that the type locality is the River Muni, which du Chaillu 

 traced to its source. 



I am not aware that attention has been called to this before, so 

 would suggest that the « River Muni » should in future be cited as 

 the type locality of the mammals described in the paper. Thèse are 

 Colobus anthracinus (which Matschie thinks may possibly prove 

 distinct from C. satanas), Cercopithecus buccalis (= cephus, L.), 

 Galago elegantulus, Vespertilio pusillus (which I cannot identify), 

 Crocidura odorata, Aethosciurus poensis subviridescens, Funisciurus 

 lemniscatus, and Myosciurus pumilus.
