Mr Etheridgc on Fossils from Boiucn River Coal field. 319 



the two great divisions of Marine and Fresli-Water as stated 

 by Mr Jack; but I feel little hesitation in saying that they 

 form portions of one continuous series. I am led to this 

 opinion by the lithological character of the specimens, and 

 the general distribution of the species. 



In conclusion, I may state that the examination of these 

 Bowen Eock fossils, so far as it has gone, leads me to regard 

 tliem as occupying a high position in the Palasozoic Series, 

 and that all purposes would best be served by regarding them 

 as of Permo- Carboniferous age. 



The distribution of the Strophalosict Clarkei, a form on 

 which I have laid considerable stress, is not confined to 

 Queensland, as we have before us the example (fig. 21) ob- 

 tained by the Eev. J. E. T. Woods from the Upper PalaBOzoic 

 rocks of New South Wales, and forwarded by him to Mr 

 Davidson. How far the discovery of such shells in New 

 South Wales and Tasmania (figs. 41 and 42) * will have an 

 influence in determining the age of the beds in which they 

 occur, it is at present idle to speculate. 



There is one point more which appears to me to be worthy 

 of consideration in conjunction with these facts, viz., the 

 strong resemblance borne by tlie Procluctns or Strophalosict last 

 described, and found in New South Wales and Tasmania (figs. 

 44 and 45) f with the typical Permian species of the genus 

 Procluct'us horridus (figs. 50 and 51).
