ston (Hobart Town), and the Rev. J. E. Tenison Woods 
(Sydney). I am indebted to Profs. Owen, F.R.S., T. Rupert 
Jones, F.R.S., G Busk, F.R.S., P. M. Duncan, F.R.S., H. A. 
Nicholson, F.G.S., and G. S. Brady, Messrs T. Davidson, F.R.S., 
W. Carruthers, F.R.S., and H. B. Brady, F.R.S., Drs R. H. 
Traquair, F.G.S., H. Woodward, F.R.S., and I. B. Balfour, F.G.S., | 
for information connected with their special subjects. To 
Messrs G. Sharman, E. T. Newton, F.G.S., and R. B. Newton 
(Mus. Pract. Geology), W. S. Dallas (Geol. Soc. Lond.), and 
C, O. Waterhouse (Brit. Mus.), I am indebted for assistance in 
unravelling obscure points in synonymy. Prof. L. G. de Ko-_ 
ninck has placed me under many obligations by his courtesy 
in forwarding advanced proofs of his fine work on the Australian 
Paleozoic Fossils, by means of which I have been able to 
complete the Catalogue at a much earlier date than other- 
wise could have oan’ done. 
Through the kindness of Prof. Geikie, F.R.S., I have had 
afforded me the opportunity of consulting a large number of 
works in the Library of the University of Edinburgh; and I 
am also under obligations for literary assistance to Prof. F. W. 
Rudler, F.G.S., and Messrs W. Rupert Jones (Geol. Soc. Lond.), 
H. B. Wheatley (R. Soc. Lond.), T. W. Newton (R. School 
Mines), R. Kippist (Linn. Soc. Lond.), J. Gordon (RB. Soe. 
Ldinb.), and F. H. Waterhouse (Zool. Soc. Lond.). Lastly, the 
encouragement afforded me by my kind friends Dr J. J. Bigsby, 
F.R.S., and Mr R. L. Jack, F.G.S. (Brisbane), and my father, 
has assisted me to surmount many difficulties. 
To the liberality and consideration of the Syndics of the 
Cambridge University Press the publication of the Catalogue of 
Australian Fossils is due, whilst to my friend the Rev. Professor 
T. G. Bonney, F.G.S., my warmest thanks must be tendered 
for bringing the manuscript under their notice.
