Three Expeditions into the Interior of Eastern Australia, Volume 2 / With Descriptions of the Recently Explored Region of Australia Felix, and of the Present Colony of New South Wales

To one or other of the two preceding gigantic species of kangaroo must be referred:

II.a. Crown of right inferior incisor, Figure 6 Plate 47.

II.b. Lower extremity of right femur.

II.c. Lower extremity of right femur, with the epiphysis separated, showing its correspondence in age with the animals to which the fossil jaws belonged.

II.d. 5th Lumbar vertebra, Figure 8 Plate 47.

II.e. 10th or 11th Caudal vertebra. The proportion of this bone indicates that these great kangaroos had a relatively stouter and perhaps shorter tail than the existing species.

Macropus sp. indeterminate. Agrees in size with Macropus major, but there is a difference in the form of the sacrum: the second vertebra of which is more compressed--to this species which cannot be determined till the teeth be found, I refer the specimens marked:

III. Sacrum.

III.a. Proximal end of left femur.

III.b. Proximal end of left tibia, in which the anterior spine sinks more gradually into the shaft than in Macropus major. As this is the only species with the skeleton of which I have been enabled to compare the preceding fragments, I am not able to pronounce as to their specific distinctness from other existing species of equal size with the Macropus major.
