Probably allied to the Welle River species described above 

 and to nigrofusca from the Semliki District. 



The colour is as follows : — " Pelage en dessus cPun noir- 

 bleu d'ardoise uniforme, en dessous plus pale ; les poils 

 d'un cendre de plomb a la base ; .... la queue noiratre en 

 dessus, brunatre en dessous." 



The second upper unicuspid (' f i z ") is stated to be larger 

 than the third or canine, which is a little longer than the 

 anterior cusp of the large premolar. 



Dimensions of the type (as given by Bocage) : — 



Head and body 70 mm. ; tail 52 ; hind foot 12. 



Hab. Qui n dumbo, Angola. 



Type. In Lisbon Museum. 



In general dental characters this species would appear to 

 agree with nigrofusca and to a certain extent with the pre- 

 ceding species; but the general dimensions and colour are very 

 different, nigrofusca being considerably browner and having 

 a larger hind foot and longer tail, while the Welle River 

 species is considerably paler in colour and with a much 

 shorter tail.

About equal in size. to turba, but with a much longer tail 

 and having the second upper unicuspids larger than the 

 third. 



Colour above dark blackish brown, the new pelage near 

 "blackish brown (1) " mixed with "mummy-brown," and 

 the worn coat about as in "mummy-brown." Flanks a 

 trifle paler, the tint merging gradually into the dull brownish 

 grey of the belly. Backs of hands and feet dark brown. 

 Tail long, dark brown above and below ; bristle-hairs con- 

 fined to basal half, not very conspicuous. 



Skull much as in turba, but with the second upper uni- 

 cuspid larger than the third. There seems to be some error 

 in Matschie's description of the unicuspids, probably due to 

 a different understanding of the dental nomenclature ; he 

 writes, " i 3 unci j>m 4 im Oberkiefer sind uugefa.hr gleich breit, 

 aber i A ist fast doppelt so gross wie c unci der vordere 

 Hocker von pm i ist wenig kleiner als c." I have accepted 

 three specimens from the Upper Congo as representing
