or less washed with a pinlush suffusion ; basal halves of belly-hairs 

 dark slaty ; line of demarcation on sides indistinct. Upper surface 

 of hands and feet white. Tail rather longer than head and body, 

 brown above, ill-defined dull buffy below. 



Skull apparently quite like that of M. rufescens, except that the 

 interorbital space is much broader, very much as in M. revoili. 



Dimensions of the type, measured by collector in the flesh: — 



Head and body 113 mm. ; tail 128 ; hind foot 32 ; ear 21. 



Skull — greatest length 36 ; basal length 31 ; zygomatic breadth 

 20 ; nasal length 13 : interorbital breadth 7'1 ; breadth of brain- 

 case 15*5 ; palate length 18-5. Combined length of last three 

 cheek-teeth (p. 4 , m. 1 , and on. 2 ) 6; length of lower tooth-row 16*5. 



Bab. Mega, Western Boran Galla, S.E. of Lake EudoK; alti- 

 tude 4500 feet. 



Type. Female (as determined by the collector). B.M. No. 

 0.11.7.11. Original number 51. Collected 9 Nov., 1899. 



This species is no doubt closely allied to M. rufescens, but differs 

 by its pinkish-washed, less snowy-white, and less defined belly, 

 dull buffy instead of white underside of tail, and its markedly 

 broader interorbital space, in which latter respect it resembles the 

 very differently coloured M. revoili.
