and New Zealand, and to have been deposited in both areas under 

 the same physical conditions, and within a common biological 

 province. 



" The attempt to correlate the lower Mesozoic formations in the 

 two countries is therefore a matter of some difficulty ; but as plant- 

 beds occur at intervals, interstratified with the marine strata of New 

 Zealand, these may be perhaps yet employed successfully as indica- 

 tions of relative age. 



" This would be a most useful labour, as the strata concerning the 

 age of which there is so much uncertainty are in Australia and India 

 of the highest economic importance from their containing workable 

 coal-seams : but while the Upper Jurassic flora is well developed in 

 New Zealand, and can be successfully compared with that of cor- 

 responding age in Australia and India, the lower plant-beds of 

 Eh^tic, Triassic, and Permian age have only yielded specimens in a 

 bad state of preservation. The following attempt at a tabular com- 

 parison of the age of the formations in the two countries is there- 

 fore not made altogether on palseontological evidence, and is only the 

 reading of the Australian record from the New Zealand point of 

 view, so far as the characters and subdivisions of the Australian 

 formations have been described by various authors.
