INAUGURAL ADDRESS. 57 



of New South Wales may prove to be on the Gympie horizon, and 

 the latter that the Gympie beds Avill prove to be identical with the 

 New South Wales strata, termed by him " Carboniferous," and 

 formerly known as •' Lower Carboniferous." The lower formation 

 of the Bowen River Series is believed to be newer than the Gympie 

 beds. 



III. STAR SERIES. 



1872. Daiktree (General Report, Northern District, p. 7) 

 places the Mount Wyatt plant-beds, with their interstratified mai-ine 

 beds, as Upper Devonian (also Quart. Journ. Geol. Soc, xxviii., 

 p. 289, 1872). 



1 878. Jack names the rocks of the Star Kiver basin the "■ Star 

 beds," and regards tnem as of Upper Devonian age. 



188;}. Woods, J. E. T. (Journ. Roy. Soc, New South Wales, 

 XVI., p. 179), announces the discovery of plant-remains in the 

 strata of the Drummond Ranj^e, Central Queensland, and ascribes 

 the age to the Lower Carboniferous. 



1886. Jack (Handbook Geol. Queensland) describes the Dots- 

 wood beds, and places them as conformably succeeding Middle 

 Devonian. 



1889. Jack (Report Sellheim Silver Field) refers to the Star 

 beds those rocks which are regarded as Lower Carboniferous. 



1892. Jack (Geol. and Pal., Queensland, p. 140) groups the 

 -whole of the above deposits under the head of the " Star Beds," 

 and he considers these superior in position to the Gympie beds. 



(c) Victoria. 

 Comijonent formations: — (x.) Bacchus Marsh sandstones and 

 conglomerates; (ii.) Avon River sandstones. 



I. BACCHUS MARSH SANDSTONES AND CONGLOMERATES. 



1861. Selwyn (Vict Exh. Essays, p. 182) refers the series to a 

 period intermediate between the Carboniferous and Permian. 



1867. McCoY (Intercol. Exh. Essays, p. 327) refers the sand- 

 stones to the Lower Mesozoic, but considers them as probably 

 inferior in position to the coal beds [of Victoria]. 



1868. Selavyn (Cat. Rocks, Nat. Mus., p. 44) speaks of the 

 series under Upper Palaeozoic. 



1873. Smyth, R. B. (Internat. Exh. Essays, p. 20), regards the 

 Gangamopteris beds at Bacchus Marsh as nearly the equivalents of 

 the Sydney Sandstone.
