284 Dr. H. A. Nicholson and Mr. R. Etheridge, Jun., on 



With regard to the first locality, we would simply point out 

 here that evidence has been elsewhere adduced by one of us 

 to show that in all probability certain of the beds of the Bowen- 

 River Coal-field, including those of Coral Creek, are of Permo- 

 Carboniferous age, with a strong leaning towards the Permian 

 aspect — and that the detailed examination of the Stenoporm 

 in no way invalidates this view, but, on the contrary, lends 

 colour to it. 



The Gympie series, from which the coral we have noticed 

 as Stenopora ? (or perhaps Monticulipora) is derived, is con- 

 sidered by Mr. R. Etheridge, F.R.S., to be of Devonian 

 age. We are not in a position either to confirm or disprove 

 this opinion, as the material examined by us throws no fresh 

 light upon the subject. 



The Fanning-River Limestone and its associated shale have 

 been shown, in the paper just referred to (as before the Geo- 

 logical Society), to possess a strong claim to be considered 

 Devonian. We have determined only two corals satisfactorily 

 from this horizon, Heliolites porosus and Pachypora meridio- 

 nalis (nobis). The former, a typical Devonian coral in Devon- 

 shire and the Eifel, supports the evidence afforded by the 

 Mollusca in a marked degree ; that of the Pachypora will be 

 considered immediately. 



We now come to the two last localities, both in the Burde- 

 kin district — a limestone developed on the Broken River and 

 Arthur's Creek, Burdekin Downs. The first point to be 

 noticed in connexion with these localities is the presence of 

 massive Favosites, of the Devonian type, quite undistinguish- 

 able from the F. gothlandicus and its variety F. Goldfnssi } of 

 the Devonian of Europe and North America. Secondly, we 

 note the presence of numerous large colonies of Heliolites^ 

 including Heliolites porosus in abundance. 



Again, strong evidence of a Devonian age is afforded by 

 the appearance here of a coral which we cannot distinguish 

 from Auhpora repens, Edw. & H., a very characteristic Devo- 

 nian species, and of the equally characteristic Devonian genus 

 Trachypora, while species of Alveolites of a Devonian type 

 are also present. Hardly less characteristic is the Pachypora 

 to which we have given the name of P. meridionalis, and 

 which is most intimately allied to the P. cervicornis, De 

 Blainv. sp., of the Devonian of Europe, and to similar or 

 identical forms in the Devonian of North America. Upon 

 the whole, therefore, putting to the evidence afforded by 

 the corals that derived from such characteristic forms as 

 Stromatopora and Caunopora, we cannot doubt that the 

 deposits now under consideration are of Devonian age. So
