Ohs The extinct "Woinhats may he divided, as they have been to a certain 
extent by Sir E Owen, into two groups — those of equal or less size than the existing 
species, and those exceeding the latter. In the first division we have P. meclius, P. 
magnus, and P. gigas ; in the second one, P. Mitohelli, P. farms, P. plafyrhinus, 
and P . Thomsoni. Professor Owen states that we are now acquainted with species of 
PJiascolomys exhibiting “gradations of bulk rising from that of a Marmot to that of a 
Tapir but it is quite open to doubt if the gigantic species burrowed, like their more 
recent and smaller brethren.

Ohs. Lower and upper jaws of this species have been discovered, indicating a 
Wombat larger than either of the two largest existing species. The lower jaw must 
have been six or seven inches in length, and the entire animal when full grown one-half 
larger than P. platyrhinus.

Ohs. The disposition of the upper molars in this species resembles that of 
P. medius, and is of the type of the existing Hairy-nosed Wombat.

Ohs. This specie^ agrees more or less in size with the existing Wombats, and is 
close to P. platyrhinus. Mr. C. W. De Vis has quite recently afforded strong evidence of 
the satisfactory specific importance of this species, by describing numerous bones other 
than those of the cranium.
