shorter. Head, long ; nose, sharp ; whiskers, extending beyond the ears. 
Fur, very soft and lustrous. The legs, feet, and heels, clothed with short, 
closely adpressed hairs, which extend beyond the nails; ears, thinly 
covered with hairs, which do not entirely conceal the colour of the 
skin ; mammae, four ; situated far back. 
COLOUR. 
Head, ears, and whole upper surface, bright orange ; the fur being for 
three-fourths of its length from the roots, dark plumbeous ; whiskers, 
nearly black, with a few white hairs interspersed ; tail, above and be- 
neath, dark brown ; throat, breast, and inner surface of the forelegs, 
white ; belly, light buff. There are no very distinct lines of separation 
between these colours.
