The correspondence with the formations of New South Wales 

 is, as might be e:i:pected, clear enough in general outline ; and it 

 may be confidently expected that between the two series a fairly 

 complete history of the East Australian Lands during the 

 Carboniferous and Mesozoic periods may be ultimately con- 

 structed. 



Victoria. 



The Geology of this Colony has been pretty well worked out in 

 many especially the mining districts ; but the Mesozoic beds 

 have received less systematic investigation ; — and it is with these 

 that we are here principally concerned. For, with the exception 

 of certain Lepidodendron beds upon the river Avon in Gippsland, 

 there is no Carboniferous record whatever in the country ; and 

 these ought very likely to be ranked as Devonian. Nor is 

 there even any Glossopteris to be quoted, whether Carboniferous 

 or Mesozoic; but the next beds the Avon sandstones — after a
