PEOCBEDINGS OF THE GEOLOGICAL SOCIETY. [April 24, 



Prom the Head of E.oper Creek and from the Bowen River : — 



Streptorhynchus DaTidsoni, Eth. PI. XVII. fig. 1. 

 Spirifera striata, Eth. PI. XVII. fig. 5. 



coiivoluta, Eth. PI. XVII. fig. 3. 



allied to bisulcata, Sow. PI. XVII. fig. 4. 



Productus Clarkei, Eth. PL XVII. fig. 2, 2a, 2h. 



From the head of the Don Eiver a suite of fossils has heen for- 

 warded by Eev. W. B. Clarke, whom we also have to thank for the 

 specimens from the Nogoa and Dawson rivers. 



These are said to overlie the auriferous series there, and consist of: — 



Murchisonia cai-inata, Eth. PI. XVIII. fig. 5. 

 Naticopsis (?) harpasformis, Eth. PI. XVIII. fig. 6. 

 Productus longispinus, Sow. PI. XVIII. fig. 9. 

 Spirifera allied to striata, Sow. PI. XVIII. fig. 8. . 

 Griffitliides dubius, Eth. PI. XVIII. fig. 7. 

 Strophomena rliomboidalis, Eth. PI. XVIII. fig. 1. 



The whole of these forms agree with those found in the Hunter- 

 river series of New South Wales, which there, as in Queensland, 

 are found at the base of the great Palaeozoic coal-group of that 

 Colony. 



A sketch section of the lowest observed coal-seams, with several 

 hundred feet of Productus beds resting on them, is here given (Fig. 9). 



This section is observed about half a mile up a creek which joins 

 the Bowen river one mile below the ford at the road crossing- from 



Pig. 9. — STcetch section of lowest ohservecl Coal-seams near the Nel)o 

 Crossing of Bowen River. 



a. Porphyrite. 



b. Freshwater shales &e., with three coal-seams. Fragments of Glossoijteris, 



but no marine shells. 



c. Proditctus- and Spirifera-heds, with abundance of Carboniferous MoUusca. 



Bowen to Kebo. The strata are here locally upheaved by the intru- 

 sion of the trap range which forms the source of the creek. At the 

 junction of the creek, however, the dip is very slight, although the 

 beds are quite conformable. The marine beds are generally argilla- 

 ceous limestones, often very ferruginous ; whilst the upper beds are 

 coarse grits and sandstones with interstratified shales. In these the 

 impressions of Glossopteris are very common and sometimes beauti- 

 fully in-eserved ; but I have never been able to find the fauna and 

 flora unmistakably represented in the same bed. 



The only section that has come under my observation in which
