MACROPUS ANAK. 
Two fragmentary mandibles are conspicuous by the size of the 
teeth they bear and the limited depth of the horizontal ramus. 
The portion of the left jaw contains two molars( Ma and M3 in 
situ.) These teeth are almost perfect; they are but little worn, 
and therefore show the very faint verticle folds on the anterior 
aspects of the lobes. The other specimen — a part of the right 
ramus — shows the last molar rising from its alveolus, and the 
preceding one up in position ; this exhibits signs of wear on the 
posterior lobe, but the very faint vertical folds or grooves are still 
visible. 
The teeth are much larger than those of Sthenurus, and can 
readily be distinguished from the molars of Ihe living species of 
Macropus] they differ somewhat from all Owen’s figures of teeth of 
the species included in the above synonym, being very broad in 
comparison with their length. 
A specimen of Macropus anak (c. 112, Q.M. 10731) in the 
Museum Collection, presented by Mr. C. W. De Vis of the 
Queensland Museum some 13 years ago, very closely resembles the 
Balladonia fossils. Upon referring to a paper by this authority,^ “ A 
Review of the Fossil Species of the Macropodidae in the Queens- 
land Museum,” this species is defined, as follows: “Molars smooth,
