Hah. and Type as above. 



This fine Dassie is quite unlike any of tlie described 

 W. African members of the genus, but presents considerable 

 resemblance to P. lojyesi, Thos. & Wrought., a native of 

 Monbuttu, in the eastern part of the Congo Forest area. 

 It is, however, rather more buffy throughout^ and its bauds 

 and feet especially are markedly more buffy than in P. lopesi, 

 where they are greyish brown.
