ANTILOPINE KANGAROO. 
situated in the palato-maxillary suture, are here represented 
by two very small perforations of about one line in length, 
and behind these are some other very small perforations; in 
fact, the palate is as entire as in M. giganteus. The fore¬ 
most incisor tooth (see PI. 5, fig. 15,) is but little broader 
than the second; the third is about double the widtli of the 
second, has a strong oblique external groove rather in front 
of the middle of the tooth, and there is a second groove in 
front of this, but this latter, which represents the foremost of 
the two grooves observed on the incisor of M. giganteus , is 
much less distinct than in that animal. In an adult skull I 
have seen the full number of molar teeth ; but the cranium 
of a very aged individual presented but thirteen molar teeth 
in both jaws. The subjoined dimensions are from two skulls 
in the collection of Mr. Gould ; the specimens were procured 
near Victoria, in North Australia, and the larger skull is said 
to have belonged to an animal weighing one hundred and 
twenty pounds, the largest which had been seen :—
