Myriolepis, which have been, by several authors, ostensibly adduced as 
evidence for a Palaeozoic facies even of the Wianamatta-Hawkesbury beds,

of India and on the former existence of an Indo-Oceanic Continent. Quart. Journ. Geol.

comparison of the various groups of the plant-bearing system in India. But 
there are also references to the Australian coal beds, especially of New South

and takes notice also of the correlations and remarks on the age of the Indian 
Damuda System, brought forward by Dr. Oldham in his above-mentioned 
papers.

large districts.
