There is a white head-spot elongated antero-posteriorly, somewhat diamond-shaped, 
beginning a little way before the level of the antecanthus of the eyes in the mesial 
line and prolonged backwards to the centre of the forehead. A broad white band 
starting from behind and a little way above the eye is prolonged obliquely downwards 
and backwards below the ear, but not beyond the posterior margin of the conch, 
unless occasionally to a limited extent in scattered white hairs. The ear black, with 
the exception of its upper border, which is white. The white oval frontal spot and the 
white band from the side of the head to the ear are surrounded with black ; the muzzle, 
lips, chin, throat, and the whole under surface brownish black; part of the sides and 
the limbs being jet-black. The occipital region is pure white and all the back 
yellowish white, with the exception of three narrow black bands, which run parallel to 
one another as far as the middle of the back, where the outer band of each side 
becomes outwardly divergent and much broader, passing obliquely downwards for a 
short way, then upwards to the side of the rump, the central line remaining uninterrupted 
and becoming broader on the loins and again narrow and prolonged a short way on to 
the tail. The tail is long and pointed, the hairs somewhat pendent; it is black 
beneath at its base, but in the rest of its extent is nearly pure white, most of the hairs 
being dark only at their extreme bases. 
The nose of this animal in profile is retrousse. Bone of penis curved and 57 mm.
