present evidence of the constancy of size, of the molar series of 
teeth in existing and extinct species of wombat, such series fully in 
place and well worn, having a longitudional extent of i inch 5 lines 
(36mm.) cannot be referred to a species with a longitudinal extent 
of molars never less than i inch 9 lines (44.5mm.) and usually more ; 
as e.g. in the Tasmanian Wombat, which is the smallest of the 
known existing species. ’ 
The four small molars of this collection when placed side by 
side measure 30mm. which, making allowance for the missing 
premolar, practically coincides with Prof. Owen’s measurement of 
I inch 5 lines for the whole cheek series. 
Diligent search among the material in this collection has failed 
to reveal the presence of any premolar teeth that might be referred 
to this species and none of the many fragmentary phascolomine 
bones identified show sufficient variation from the latifront type to 
warrant their inclusion under another species. 
This animal which has previously been recorded from New 
South Wales and Queensland must have had a range extending 
over the whole of the Continent. It is new to this State.

From the time that the first recognised remains of animals of 
this genus were described in the Philosophical Transactions of the 
Royal Society for 1859, there has been a great amount of discussion 
as to the nature of the food of this gigantic relation of the 
Phalangers. 
Prof. Owen stoutly asserted that the animal was a carnivore, 
pointing out the great resemblance between its sectorial cheek

in length, equal to i inch 10 lines.
