ACKNOWLEDGMENTS. 
The writer is indebted chiefly to Professor Sir Edgeworth David, F.R.S. 
not only for his introduction to geological science, but for the discussion 
of many of the points raised during the compilation of this paper. 
is also анна to Dr. Walkom’s remarkable work оп the Mesozoic 
flora, and discussion of Australasian Mesozoic palaeogeography, which, with 
Piroutet’s work on New Caledonia, that of Arber, Trechmann, Woods 
and Wilckens on New Zealand, and his own on the Carboniferous and 
Devonian fossils of Australia, and on the recent advances in the geology 
of New Zealand, suggested the present paper. He has also received the 
friendly help in various ways of Messrs. F. Chapman, A. G. Maitland, 
Loftus Hills, L. K. Ward, Morgan, Professor Richards, Professor 
Elder, G. E. Harris, and several others, to whom his best thanks are due. 
ADDENDUM. 
Concerning the relationship of the **Permo-Carboniferous" fauna of 
Western Australia to that of the East Indies, reference should be made 
to the following paper read before the Royal Society of New South Wales 
in December, 1922, by Mr. W. S. Dun and Professor Sir Edgeworth David: 
* Notes on the Occurrence of Gastrioceras at the Irwin River Coalfield, 
Western Australia, and a Comparison with the so-called Paralegoceras from 
Letti, Dutch East Indies."
