There have been two other species of Diprotodon obtained 
in Australia, one of which was a very gigantic form, on the 
average: about six feet high and ten feet long, its skull 
measuring nearly three feet in length, and named by Sir 
Richard Owen D. australis, the other a slightly smaller form 
named by Professor Huxley D. minor. 
The next remains of interest from your local deposit are 
those of the extinct Wombat—Phascolomys pliocenus, McCoy 
—a very fine lower jaw being preserved in the National 
Museum. Professor Sir Frederick McCoy remarks in one of 
his early articles that this species is easily distinguished from 
the three living species of the same size by the greater antero- 
posterior length of the grinders. Our living species Phas- 
colomys platyrhinus Owen, or the Naked-nosed Wombat, 
being one of the above. From other fossil forms from New 
South Wales and elsewhere, it is also readily distinguished 
by many characters unnecessary to mention here. 
The remaining fossil forms occurring to my knowledge 
belong to the Mollusca, and as the deposit is without doubt a 
freshwater limestone, we get, as would be expected, the 
remains of freshwater univalves and bivalves. These fossils 
occur for the most part as casts and impressions, and it is 
only by collecting numerous examples of every form that 
anything can be done in the way of identification. “Casts 
eing at best somewhat unsatisfactory, it is only by the 
examination of large series of specimens that we may hope 
for enlightenment on the freshwater fauna of the Diprotodon 
period. 
A similar deposit to that at Limeburners’ Point occurs 
in the Lara district, which is perhaps not quite so accessible 
to all the members, but I hope it may be to some, and that 
they will use their opportunities to procure specimens to 
enrich the excellent local museum at the College. A sample 
of rock from this locality was also analysed in the early days 
with the following result :—

From this deposit I have seen some well preserved fresh- 
. water mussels ( Unio), closely related to, if not identical with 
. Unio australis, Lamarck, and have several times heard of 
bones and other fossils being met with by the quarrymen. 
It seems to be a very great pity that an endeavour should 
not be made to save more material from destruction. Some 
of the members could perhaps move in the matter, and try 
and persuade the owners of the quarries to get their men to 
save anything they come across, in order that the remains
