190 OBSERVATIONS ON THE ANATOMY OF 
lobe projecting from the septum over each nostril, and they 
are thereby removed considerably from each other, as in 
the Opossum. The tongue is very long, flat, narrow, ra- 
ther thin, of equal breadth from its root to near its extre- 
mity, which has an elliptical form ; it measures three inches 
from the root to the apex, and is quite free for nearly two 
inches from the frenum. This freedom of motion of the 
tongue corresponds with the wide gap of the mouth, and 
the lengthened form of the jaws, and may indicate the aid 
required from this organ in seizing or collecting food. The 
ears are long, broad, elliptical at their apex, thin, soft, and 
scantily covered with small, dark, very short hairs. The 
eyes are rather small ; their position lateral, and inclined a 
little upwards and forwards. The memhrana rdctitans is 
large and strong, and can be drawn more than half-rway 
over the cornea. The margins of the eye-lids and the sur- 
rounding hairs are of a black colour. There are no dis- 
tinct cilia, nor caruncula lachrymalis, but in the situation 
of the latter there is a thickened fold of the tunica con- 
junctiva. The anterior canthus of the eye is very acute, 
and prolonged forward ; the posterior canthus is rounded, 
and nearly imperceptible, which gives to the eye a pecu- 
liar expression of cunning. The neck is short, thick, 
round, and scarcely distinguishable from the head. The 
body is nearly cylindrical, slightly compressed, equal ; be- 
coming only a few lines thicker in the region of the loins. 
The fore-legs are two inches shorter than the hind pair, of 
a tapering form, susceptible of free supination and prona- 
tion, the radius and ulna being separate and moveable. 
The flexor muscles of the humerus are remarkably strong, 
which, with the form and length of the claws, might lead 
one to suppose that the animal occasionally sought its food 
by scraping or digging the ground. Length of the hume- 
rus \\ inch; ulna (from the point of the olacranon), 2
