56 INAUGURAL ADDRESS. 



1892. Jack (Geol. and Pal., Queensland, p. 142) considers the 

 Lepidodendron beds of New South Wales to be appvoximately on 

 the horizon of the Star Series in Queensland.

I. BOAVEN RIVER SERIES. 



1847. Leichhardt ("Overland Exped.") discovers coal beds 

 at Bowen River. 



1872. Daintree (Quart. Journ. Geol. Soc, vol. xxviii.,p. 286) 

 recognises the Carboniferous age of the rocks and fossils of the 

 Bowen river and other northern coalfields. 



1879. Jack (Report on Bowen River Coalfield) sub-divides 

 the series into three formations. 



1880. Etheridge, R., jun. (Proc. R. Phys. Soc, Edinb., v., 

 p. 319), considers the L. and .M. Bowen River formations to homo- 

 taxially represent the Carboniferous and Permian of Europe, and 

 proposes to call the series Permo-Carboniferous. 



1892. The authors of the "Geology and Pal8eontolo<iy of Queens- 

 land," p. 71, apply the term Permo-Carboniferous to the whole of 

 the similar formations in Queensland and New South Wales. 



II. GYMPIE series. 



1867. Aplik (Report, Auriferous Country, Upper Condamine) 

 discovers fossiliferous rocks at Lucky Valley and Gympie, which 

 he regarded as Silurian. 



1868. Clarke, W. B. (Proc. Roy. Soc, N.S.W., vol. i., p. 7), 

 refers the rocks and fossils on the Mary River, at Gympie, to some 

 part of the Carboniferous. 



1872. Daintree (Quart. Journ. Geol. Soc, xxviii., pp. 286, 

 289) recognises the Carboniferous age of the Don River fossils, but 

 refers those of the Gymjjie mining district to the Devonian. 



1879. Gregory, A. C. (Report Geol. Features, S. E. Queens- 

 land, p. 7), classes the altered slates of Moreton Bay and Darling 

 River Downs and the Gympie beds as Devonian. 



1886. Jack (Handbook Geol. of Queensland) names the Gympie 

 beds, removes them to Lower Carboniferous, and transfers to them 

 all of the previously so-called Silurian and large areas hitherto 

 regarded as Devonian. 



1892. Jack and Etheridge (Geol. and Pal., Queensland, p. 

 97). — The former thinks it likely that some of the cave limestones
