338 AUSTRALIAN, SOUTH AFRICAN, AND INDIAN COAL-MEASURES, 



Labyrinthodont remains, but from the Wianamatta Mr. Etheridge 

 (in his report mentioned above) also describes two species of Unio 

 and two species of Unionella. 



It seems a plausible hypothesis that the Upper Clarence Beds 

 may have been more or less contemporary with the Wianamatta 

 Shales. But, in any case, above these Wianamatta or Upper 

 Clarence beds we have no later formation, marine or fresh-water, 

 on the eastern side of the colony, — but on the right bank of the 

 Darling we find the Cretaceous marine beds which are so largely 

 developed in Queensland, and which probably come near the 

 marine beds of Uitenhage in South Africa. 



The whole series — as determined from the work of the Rev. W. 

 B. Clarke, Mr. Wilkinson, Mr. David, Mr. Etheridge and the Rev. 

 J. M. Curran, is as follows : —
