stone on the horizon of the Gympie beds (Permo-Carboniferous), 

 chiefly relying apparently on the opinion of the Survey Col- 

 lector, the late Mr. James Smith. At the same time I pointed 

 out in a foot-note that the unpublished fossils, so far as I had 

 seen them, appeared to indicate the Burdekin beds as the more 

 appropriate horizon to which the Raglan Limestone should be 

 referred. The fossils collected by Mr. Smith consist of a massive 

 Favosiles, and Cystiphyll<nd corals apparently referable to the 

 Genus Actinocystis. 



The Favosites present all the characters of the specimens 

 described by Prof. H. A. Nicholson and the writer* from the 

 Burdekin beds of the Broken Biver, as F. gothlancUca, in flat, or 

 more or less hemispherical expansions. The thin walls of the 

 corallites are well preserved, the latter being very regularly 

 pentagonal, hexagonal, or at times even heptagonal. The corallites 

 measure one line or less, in diameter. The tabulte are mostly 

 horizontal, a few olilique, or con^-ex upwards, again here and there 

 a rolling or imperfect and vesicular tabulum may be seen, but 

 interlocking and strictly concave tabulae I have not observed. 

 The walls have undergone so much alteration during their conver- 

 sion into granular calcite that all trace of pores is obliterated. 



The Actinocystis will be found described on p. 524. 



The fossils are from Langmorn Creek, Raglan, twelve miles 

 west of Keppel. 



Under the Gympie Series was also j)rovisionally included the 

 Chillagoe Limestones, near Zillmanton.f Mr. Jack made the 

 following remarks on this subject : — " Near the Dorothy Mine I 

 obtained some specimens of Corals and Encrinite stems, but from 

 their state of preservation I do not think that the most expert 

 Palaeontologist could determine either genus or species. Similar 

 fossils were obtained from the quartzites associated with the 

 limestones near Zillmanton, but in no more recognizable. condition. 



It may be observed that the Mitchell and Palmer 



Limestones bear a very marked lithological resemblance to the
