GIANT WOMBAT. 
This animal is represented by a number of teeth, of which 
several are practically perfect. They include the right lower 
premolar (PM4), the right lower first molar (Mi), the left lower 
first molar (Mi), a lower molar which could not be definitely 
placed, and seven or eight fragmentary cheek teeth. In size these 
teeth are rather smaller than most of the examples figured by Prof. 
Owen in the Phil. Trans, of 1872, but the teeth shown in figure 6, 
plate XL., of that volume have the same dimensions as the 
Balladonia specimens, which, therefore, may be regarded as 
belonging to an animal of the same species. In life it must have 
equalled a tapir or donkey in size. 
The discovery of these remains considerably extends the 
known area of distribution of P. gigas, for the animal has not 
previously been recorded from Western Australia. Possibly the 
collection of further specimens may enable a final decision to be 
arrived at in reference to the relationship of Phascolonus and 
Sceparnodon.
