South Wales. This specimen (fig. 37) agrees with the examples figured in the ' Phil. Trans.' 1874, pi. xxiii. figs. 4-9 ('Extinct Mammals of Australia,' pi. ixxxiii. figs. 4-9), under the name of Protemnodon anaJc. The third premolar, although relatively shorter, agrees in tooth of M. anak, instead of with the present form, to which he referred the upper jaw of M. anah. In bis earlier ' Catalogue of Fossil Mammalia in the Museum of the College of Surgeons,' the above-mentioned maxillte were correctly referred to M. atlas. Owing to this confusion the upper jaws of several species of Macropus were referred to Sthenurus, and their lower jaws to the so-called Protemnodon, which was really founded upon the upper jaw of Sthenurus atlas. ^ In Mitcljcll's'Three Expeditions into Australia,' 2nd ed. vol. ii. p. 359 {l^^S).—Macropus. ^ Loc. cit. 2 Phil.
