The Coast région. 



Around the Lower Congo river Cercopithccus ascaniiis ascaniiis 

 and C. cep/ius live in tlie forests, and there is also the home for 

 Matschie's CcrcopithecHS cynosiirus Weynsi, which probably like 

 its congeners prefers more open countrj with scattered trees and 

 smaller groves. 



Colobus palliatus angohnsis has also been quoted for the Lower 

 Congo région below Leopoldville. 



Also with regard to the distribution of other animais the coast 

 région round Lower Congo shows affinity with Angola. 



Perodicticus Arrhenii Lônnberg. 



Ç Masisi (Bonnevie), n° 3187. 



With the exception of its slightl3' larger molars the spécimen 

 from Masisi ver_y nearly agrées with the type. 



To the same species are also to be referred two mounted spéci- 

 mens, one which is said to be from « Haut-Congo » and another 

 from Panga, Stanles ville district. This indicates that this Potto 

 is distribiited fairly widely in the great Congo forest. 



There are also three flat, partly incomplète skins which are from 

 Baraka. Thèse resemble essentiallv in colour those mentioned 

 above, and one of them, which still is provided with a tail proves 

 that they hâve belonged to a relatively long-tailed animal, with the 

 organ mentioned of approximatelv the same length as in P. Arrhe- 

 nii^ viz. about 6 '/o cm. It appears thus probable that this Potto is 

 identical with, or perhaps represents a local race of this one, 

 althoiigh the available material does not allow a definite opinion. 

 By this the probable distribution of the species extends even so far 

 south as to the western shores of Tanganyika.
