procuring the worms and insects on which it feeds. The openings of the nostrils are 
situated in the centre of the radiated disc. The number of the caruncles is about twenty. 
On account of the proportionately lengthened tail, the animal is sometimes called the 
Long-tailed Mole ; for the tail is two inches and a half in length, while the head and body 
only measure four inches and a half. Another name by which it is known is the 
Condylure, or “knotty tail,” an epithet which has been applied to it because, when a 
specimen is dried, the skin of the tail contracts so firmly over the vertebre that the separate 
bones exhibit their form through the skin, and give to the tail a knotted aspect. The 
colour of the fur is much like that of the common Mole, being a velvety blackish-grey on 
the upper portions of the body, and paler on the under parts. The eyes are extremely 
se ane there is no external indication of ears. It is an inhabitant of Canada and the 
nited States.

THE insect-eating animals which have already been described are in the habit of 
searching for their prey under the surface of the earth, and are furnished with extremely 
imperfect means of sight. But the curious examples of Insectivora which are collected 
into the single genus Tupaia are of a very different nature, living in the full light of day, 
and seeking their insect prey among the branches of the trees on which they dwell. It 
needs, therefore, that animals which obtain their food in such a manner should be endowed 
with excellent powers of vision; and we find accordingly that the Tupaias—which 
animals will be represented by two examples—are furnished with good eyes and quick 
sight. Indeed, the entire aspect of these creatures reminds the observer more of the 
squirrels than of the moles. The Tupaias are inhabitants of Sumatra and parts of India. 
The head of this animal is very singular in its shape, which is well represented in 
the engraving. The upper jaw is slightly longer than the lower, and the muzzle con- 
siderably produced, so that the head has a strangely dragon-like aspect, which is 
heightened by the position of the ears, which are set very far back, and by the long 
sharp rows of teeth which arm each jaw. The long bushy tail of the Tupaia gives it a 
kind of resemblance to the squirrel, a resemblance which is appreciated by the native
