“ MAMMALIA. : 149: 
of the back is grizzled or hoary *, the white predominating over the black, and the light-brown 
of the shorter wool being also more er less seen, according as the fur is in good or bad order. 
The sides of the upper-lip, the point of the chin, the cheeks, and the sides of the neck, are 
soiled, reddish-white, which mixes gradually with the dark colour of the head. The under. 
parts, including the throat, breast, belly, and fore and hind legs, are of a reddish-orange 
colour, without mixture. The fur there is thinner and rather shorter than on the back, of the 
same colour, for its whole length, and there is very little of the fine wool amongst it. On the 
sides the soft wool has reddish-orange tips, and is mixed with a few long, reddish-white hairs, 
forming a gradation betwixt the colours of the back and belly. 
The tai/ is flattish, but not distichous; it is nearly linear, and is rounded at the tip. It is 
well clothed with hair, a little longer than that on the back, and is dusky above, from an 
intimate mixture of brownish-white and blackish-brown hairs, and is brownish-black under- 
neath, and at the tip. In some specimens the tail is almost entirely dark-brown, with a very. 
slight sprinkling of hoary hairs. Legs, very short, and muscular. Fore-feet, with four toes, 
and the minute rudiment of a thumb. The toes are well separated, not being connected by 
the skin for more than a third part of the first joint. ‘The palms are naked, and have three 
tubercles at the roots of the toes, and two much larger ones further back, of which the largest 
has a minute rudiment of a thumb on its inner side, covered by a small triangular nail. The 
middle toe is the longest; the first and third, which are equal to each other, are but a little 
shorter, and the outer one is rather more than the length of its nail shorter than these. All 
the toes are covered with a smooth coat of hair above, and are perfectly naked underneath. 
The fore-claws are slightly arched, and rather obtuse; they are so much compressed, that 
there is merely a slight excavation near the tip undermeath, their edges from thence to their 
roots being in contact ; and their size, as compared with each other, is proportional to the toes 
to which they belong. The soles of the hind-feet are long and naked to the heel ; the callous 
tubercles are not so conspicuous as in the fore-feet. There are five hind-toes, which are 
about the same size with the fore-ones. The middle claw projects a very little beyond the 
one on each side of it. ‘The outer toe is more than the length of its claw shorter, and the 
inner one is still shorter and further back. 
When the fur is out of season it loses its lustre, and the down and most of the hair on the 
belly falls off, so that the animal can scarcely be recognised.
