Size of M. ruficollis. Form very slender and graceful. Pur soft, 

 almost wooUy. General colour clear grey, with a bluish tinge, 

 rump rather more rufous. Underfur thin and sparse, pale grey. 

 Face-markings distinct and well defined ; top of muzzle brown, 

 slightly paler than the two dark whisker-marks ; cheek-stripe 

 pure white and sharply defined, passing backwards to beneath the 

 eye ; a grey band passing backwards from the angle of the mouth 

 betwpen the cheek-stripe and the white chin. Crown of head grey, 

 becoming whiter between the ears, the white passing backwards as 

 a nuchal stripe to about halfway down the neck ; a darker 

 mark on each side of it. Ears unusually long, their interior 

 white, their exterior parti-coloured, brown for the basal half, then 

 white and the extreme tips brown. Sides of rump white, but this 

 not corresponding in any way to the white femoral stripes of other 

 species. Chin , pure white ; chest, belly, and inner sides of limbs 

 greyish white. Arms and legs grey like the body, hands and feet 

 gradually becoming nearly or quite black on the digits. Tail very 

 long, pale grey, an inconspicuous black or grey crest below the tip. 



Skull. General form much as in M. ruficollis. Eelative propor- 

 tions of brain-case and face medium (index about 230). PremaxiDse 

 very oblique, projecting far beyond the nasals. Nasals very slightly 

 expanded behind. Interorbital region broad, the supraorbital edges 

 strong, thickened, and developing short but distinct postorbital pro- 

 cesses, behind which there is a feebly marked intertemporal constric- 

 tion. Top of crown unusually convex, the parietal region bent 

 down at a very considerable angle to the line of the face. Infra- 

 orbital opening about 9 or 10 millim. from orbit. Palate with two 

 large vacuities, each about as large as two of the molars combined.
