14. Sylvisorex oriundus sp. now 



(Plate VII, Fig. 7; IX, Figs. 4, 4a; XI, Fig. 1.) 



Type, No. 48554, Amer. Mus. Nat. Hist., skin and skull of adult 9 (teeth little 

 worn) collected at Medje, Nava River, Belgian Congo, May 20, 1914, by Herbert 

 Lang and James P. Chapin. Orig. No. 2368. 



A large, short tailed, short furred, dark bellied species related to Sylvisorex morio 

 (Gray), but larger, with much larger hind foot. 



Color. — Upperparts from nose to tip of tail dark olive brown, or, in certain lights, 

 dark sepia; the underfur deep neutral gray. Lower sides and underparts slightly 

 paler, dark grayish brown, very slightly lighter on throat. Tail slightly darker than 

 body above, lighter brown on basal two-thirds below. Hands and feet light buffy 

 brown, the ankles blackish. 



Skull and teeth. — Skull larger than in S. morio, with longer tooth row. Compared 

 with the figure of the dentition of the type specimen of S. inorio, 1 the second upper 

 unicuspid tooth is relatively much smaller; the front face of the large cusp of pra 4 

 is much less sloping, the heel of this tooth smaller, and the anterior cusp, though little 

 worn, is not more than half the height of the last unicuspid. The whole dentition is,
