Macropus atlas, Owen.
a. permanent false molar, in the alveolus.

Lowest jaw of largest living species of kangaroo. (Macropus major.)
In the fossils above enumerated, several species are larger than the largest living ones of the same genera now known in Australia. The annexed figure of the right side of a lower jaw of a kangaroo (Macropus atlas, Owen) will at once be seen to exceed in magnitude the corresponding part of the largest living kangaroo, which is represented in [fig. 127.] In both these specimens part of the substance of the jaw has been broken open, so as to show the permanent false molar (a. [fig. 126.]) concealed in the socket. From the fact of this molar not having been cut, we learn that the individual was young, and had not shed its first teeth. In [fig. 128.] a front tooth of the same species of kangaroo is represented.
