The age of these teds appears to he fairly marked out. “ The Fanning River 
Limestone and its a.ssociated shale have been shown to possess a strong claim to be con- 
sidered Devonian. We have determined only two corals satisfactorily from this horizon 
Heliolites porosa and Fachypora meridionalis (siohis). The former, a typical Devonian 
coral in Devonshire and the Eifel, supports the evidence afforded by the mollusca in a 
marked degree ; that of the Fachypora will be considered immediately. 
“ We now come to the two localities, both in the Burdekin district — a limestone 
develojied on the Broken River and Arthur’s Creek, Burdekin Downs. The first point to 
be noticed in connection with these localities is the presence of massive Favosites of the 
Devonian type, q^uite undistinguishablc from the F. golMandicus and its variety F. 
Goldf ussi, of the Devonian of Europe and North America. Secondly, we note the 
presence of numerous large colonies of Heliolites, including Heliolites porosa in 
abundance. 
“ Again, strong evidence of a Devonian age is afforded by the appearance here 
of a coral which we cannot distinguish from Aulopora repens, Edw. and II., a very 
characteristic Devonian species of the equally characteristic Devonian genus Trachypora ; 
while species of Alveolites of a Devonian type are also present. Hardly less characteristic 
is the Fachypora to which we have giv’on the name of F. meridionalis, and which is 
most intimately allied to F. cervicornis, De Blainv., sp., of the Devonian of Europe, aud 
to similar or identical forms in the Devonian of North America.”* 
Lastly, in the Reid Gap Limestone we again find Fachypora meridionalis and 
Heliolites in abundance, together with Stromatopora, and the characteristic genus 
Cystiphyllum, represented by a species of a markedly Devonian aspect, and other 
Rugose corals indicating a similar horizon. “ Upon the whole, therefore, putting to the 
evidence afforded by the corals, that derived from such characteristic forms as Stroma- 
topora and Gaunopora, we cannot doubt that the deposits now under consideration are
