are the shortest, next them the first, and the longest one is the second. The claws of 
the fingers are smaller, but of the same form as those of the toes. 
The tail is depressed, and does not attain quite half the length of the head and body 
together. It is, except at the base, where the fur is like that of the body, well covered 
with stiffer hair, which gradually increases in length as it approaches the end of the 
tail, reaching a length of 5 centimetres. 
The upper parts are ashy-grey, delicately suffused with black; the sides lighter greyish ; 
the underside from chin to tail, the inner side of the extremities, and the upperside of 
-the hands and feet greyish white; the lips, the two lower rows of the moustaches, a small 
patch behind the base, and the stiff hair in front of the ears white. The upper rows of 
the moustaches and the claws are black. ‘The stiff hairs of the tail have their bases 
orange-yellow, then a very large black ring, a subterminal large greyish-white ring, and 
the points black. All the soft fur of the body has the greater, basal part lead-coloured ; 
that of the upper parts has a large subterminal yellowish-grey ring, and the extreme end 
black—except some longer hairs with long black points. The hair of the under parts 
is lead-coloured, with white points.
