This fine Dassie is quite unlike any of the described 

 W. African members of the j^enus, but presents considerable 

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

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

 It is^ liowever, rather more buffy throughout, and its liands 

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

 Trhere they are greyisli broAvn.
