THE SLOW-PACED LORIS. 107 
The Stow-PacEeD Loris, or KuUKANG, is very similar in its habits to the animal just 
mentioned, but differs from it in size, colour, and several parts of its form. 
The fur is of a texture rather more woolly than that of the Slender Loris, and its 
colour has something of a chestnut tinge running through it, although some specimens 
are nearly as grey as the Slender Loris. As may be seen from the engraving, a dark stripe 
surrounds the eyes, ears, and back of the head, reaching to the corners of the mouth. 
From thence it runs along the entire length of the spine. The colour of this dark band 
is a deep chestnut. It is rather larger than the preceding animal, being a little more than 
a foot in length. 
In the formation of these creatures some very curious structures are found, among 
which is the singular grouping of arteries and veins in the limbs. 
Instead of the usual tree-like mode in which the limbs of most animals are supplied 
with blood,—one large trunk-vessel entering the limb, and then branching off into nume- 
rous subdivisions,—the limbs of the Loris are furnished with blood upon a strangely modified 
system. The arteries and veins as they enter and leave the limb, are suddenly divided

into a great number of cylindrical vessels, lying close to each other for some distance, 
and giving off their tubes to the different parts of the limb. It is possible that to this 
formation may be owing the power of silent movement and slow patience which has been 
mentioned as the property of these monkeys, for a very similar structure is found to exist 
in the sloth. 
The tongue of the Loris is aided in its task by a plate of cartilage, by which it is sup- 
ported, and which is, indeed, an enlargement of the tendinous band that is found under 
the root of the tongue. It is much thicker at its base than at the extremity, which is so 
deeply notched that it seems to have been slit with a knife. It is so conspicuous an 
organ, that it has been often described as a second tongue. The throat and vocal organs 
seem to be but little developed, as is consistent with the habits of an animal whose very 
subsistence depends upon its silence. Excepting when irritated, it seldom or never utters 
a sound; and even then, its vocal powers seem to be linited to a little monotonous 
plaintive cry. 
In captivity, this Loris appears to be tolerably omnivorous, eating both animal and
