.MAMMALS FROM MKNTAWEl 669 



(xend'al characters as in S. erylhraeus and S. caslaneiventris, 

 but belly black. 



Size and colouration of upper parts, outer sides of limbs and 

 tail almost exactly as in dark examples of S. caslaneiventrà, l)ut 

 tiie cheeks and ears are nearly or quite black, the upper sides 

 of the feet are blackish to the wrists and ankles, and the ter- 

 minal hairs of the tail are similarly grizzled to those of the 

 base. Whole of under surface, and inner sides of limbs dark 

 smoky black, with a few scattered white hairs intermingled. 

 Foot very broad and short ; the proximal third of its sole hairy. 

 MamnicC only four in number, one pair ventral and one pair 

 inguinal. 



Skull and teeth apparently not distinguishable from those of 

 S. castaneiventris; p 3 well developed, cylindrical. 



This peculiar species is evidently closely allied to S. enjlhraeus 

 and .S'. castane ivenf /is J, but its black belly readily distinguishes 

 it from either of them, as from every other known species of 

 the genus.
