the ears are of moderate size and rounded form ; the feet are of mo- 

 derate size ; the tail is nearly equal to the head and body in length, 

 thick at the base, covered with small adpressed harsh hairs ; but these 

 are not sufficiently numerous to hide the scales ; about one third of the 

 tail at the base is of a deep brown colour, the hairs covering the re- 

 maining portion are pure white, and the skin itself has evidently 

 been of a paler hue than on the basal part of the tail. The fur on 

 the body is somewhat adpressed, and the hairs are glossy on the back ; 

 they are of an ashy-gray colour at the base ; the apical half of each 

 is brownish-yellow, but at the points many of them are brownish; 

 many longer hairs intermixed with the ordinary fur of the back are 

 almost entirely of a brownish-black colour. The whole of the under 

 parts of the head and body and inner side of the limbs are white ; 

 the hairs on the belly are rather scanty, and of an uniform colour to 

 the root : the fore feet are whitish, and the tarsi are white, but 

 clouded with brown in the middle. The ears are but sparingly 

 clothed with short hairs, which on the inner side are whitish, and on 

 the outer brown.
