crossing, and were obtained personally by Mr Jack. The 

 specimens are four in number, two of them being Glossopteris, 

 and the others doubtful. 



From the beds forming the second or Fresh-Water Series 

 the remains are almost wholly those of plants, chiefly con- 

 sisting of Glossopteris and Phyllotheca, which will be described 

 in detail by Mr Carruthers. The point I wish to call atten- 

 tion to is the occurrence in this series of a bed at two different 

 localities containing not only Marine fossils, but fossils of 

 an undoubtedly Upper Palaeozoic facies. 



As before stated, Mr Jack has not supplied me with details 

 of the stratigraphical relations of these beds one with the 

 other, but with the view of showing that no mistake can 

 exist, I quote from his list of localities as follows : 



"Nos. 187 to 189 (inch) Eosella Creek, two miles above 

 Havilah Paddock, collected by E. L. J. (a Marine bed in the 

 Fresh- Water Series)." 



" Nos. 190 to 213 (inch) Havilah-Byerwin Eoad, one mile 

 south of Eosella Creek crossing, collected by E. L. J. (a Marine 

 bed in the Fresh- Water Series)." 



JSTow the importance of these facts must not be overlooked. 

 In the case of the Coral Creek deposit we have an assemblage 

 of fossils most carefully collected, and all presenting traces of 

 one and the same matrix. An undoubted Glossopteris occurs 

 here, near G. ampla (Dana)* (No. 115) in company with 

 Polyzoa of an Upper Palaeozoic type, such as Fenestella, Pro- 

 toretepora, two species of Stenopora, a specimen which is either 

 a Productus or a Sfrophalosia (No. 99), probably the latter ; 

 bivalves of the genera Pachydomtcs and Ma^onia, another 

 which I cannot distinguish from Avicidopecten limceformis 

 (Morris), and certainly Pterinea macroptera (Morris).*f An 

 assemblage of fossils such as this would have been considered 

 by all those who have in previous years written on the sub- 

 ject, Professors Morris, M'Coy, Dana, Jukes, Mr Daintree 

 and others, as representing the Upper Palaeozoic Series of 

 New South Wales, etc.

 f The remains of the Glossopteris actually occur in the same block of 

 matrix with certain of these fossils.
