accepting the identification of the Bacchus Marsh and Upper 

 Marine Glacial and Boulder beds. It seems to me that the 

 evidence is in favour of Feistmantel's correlation of the Lower 

 Bacchus Marsh beds with the blank space above the Newcastle 

 series, in which case the overlying Tceniopteris beds come out 

 directly in their accepted position, equivalents of the Clarence 

 Biver and Hawkesbury deposits.* 



The Victorian series is, therefore, apparently to be rearranged 

 as follows, by an adaptation of the list given in Murray's Geology 

 of Victoria, p. 85. 



1, 2, 3. — Carbonaceous rocks of the Wannon, Cape Otway, 

 Western Port, and North Gippsland — Coal Measures and 

 sandstones — corresponding to the Clarence River series 

 with the intercalated Hawkesbury sandstones, which are 

 probably represented by similar fluviatile formations in 

 Victoria, especially in the Cape Otway district. 

 5. — Bacchus Marsh conglomerates and sandstones with evi- 

 dence of Glacial action, and with Gangamopteris, corres- 

 ponding to some part of the great blank in the New South 

 Wales record, between the Newcastle Coal Measures and 

 the Ivake Macquarie conglomerate. 

 6-12. — No record of any part of the period which elapsed 

 between the close of the Lepidodendron era in New South 

 Wales (Stroud, &c.,), and the uppermost Newcastle beds ; 

 that is to say, of the whole Glossopteris period, together 

 with the undefined age of change which immediately 

 preceded it. 

 13. — Lepidodendron beds on the Avon, Gippsland, correspond- 

 ing to those of New South Wales. 

 I should wisli to draw particular attention to the Glacial 

 character of the Bacchus Marsh conglomerates, as indicating that 



* This was practically Feistmantel's conclusion before the Clarence 

 River beds were removed to their true position, before the discovery of 

 Labyrinthodonts in the Hawkesbury sandstones, and, of course, before Mr. 

 Wilkinson's discovery of the intercalation of the latter formation between 

 the lower and upper members of the Clarence River beds.
