114 PALHONTOLOGICAL EVIDENCE OF 
fossil representatives elsewhere. This inquiry means, Where do 
we find anything /éke our fossils? The solution of these questions, 
as far as our knowle ge goes, will materially help to clear the 
ground of at least some of the obscurity which at present rests 
upon it. 
But, before I do this, I must define what I mean by our Ter- 
and unquestionable. I mean only the great Tertiary formation 
which extends, with the interruptions T have a ready described, 
from the river ‘Murray to Gipps Land, and from Tasmania some 
distance inland in South Australia. In this formation there are 
by European geologists ; but the Pliocene of Italy, the Miocene 
of Vienna, Touraine, and Malta, and the Eocene of Paris and 
London, not more widely separated than the Murray and 
Tasmanian beds the Muddy Creek, Western Port, Onkaparinga,

e represented in Victoria,in the south-eastern dis- 
trict f South Australia, and North Tasmania. There are various 
cene and Pliocene by geologists in Australia. A succession is 
established by the Victorian Geological Survey, and to this I may 
say that I adhere: regarding the Tasmanian’ beds as the equiva-

the a formation as lower than anything we have in Victoria 
or South Australia.
