teeth in the upper "jaw agree with the Ho g; and thofe
in the lower, in number, with the. ScaLpris dentata; ; but

The grinders would feem to be a.mixture of Hog. and
Ruminants; the enamel on their external, and grinding

than points^ There are fix incifors in the upper jaw,
and only two in the lower; but thefe;tw<> are,fo ^placed
as to oppofe thofe o f the upper; five grinders in eachfide
o f each jaw, the moft anterior of which is-fmall. The pro- ’
portions of fome of the parts of this animal bear no analogy
to what is common ih moft others. The difproportions in
the length between the fore legs and the hind - are very
confiderable ; alfo in their ftrength; yet. perhaps not more
than in-the Jerboa. This difproportion between the fere legs
and the hind is principally in the more adult; for in the very
young, about the fize of a half grown rat, they are pretty

o f the different parts of which*the hind legs'are compofed,
are very différent. The thigh of the Kangaroo is extremely
