30 THE SLOW-PACED LORIS. 
ning speed, and with a movement so rapid that the eye can hardly follow it, 
the bird is torn from its perch, and almost before its eyes are opened from 
slumber, they are closed for ever in death. 
The SLOW-PACED LORIS, or KUKANG, 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. 
KUKANG, OR SLOW-PACED LORIS.—(Ayelacebus Favarincus.) 
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 numerous 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.
