CARBONIFEROUS AND PERMO-CARBONIFE ilOUS ROCKS, N.S.W. 309 



Kimberley. — Between the Gascoyne area aod Darwin is 

 the well known region, the Kimberley District of West 

 Australia. The Permo-Oarboniferous or Carboniferous 

 fossils from the Kimberley district of West Australia are 

 almost certainly the equivalents of those of the Irwin area, 

 and have similar strata, barren of fossils and consisting of 

 gypseous and saliferous strata, underlying them. It may 

 be noted that Mr. R. Etheridge, Jun. 1 has recorded a 

 Favosite (F. Marmionensis) from these strata. Splrifera 

 marcoui (Waagen) is also characteristic, and would indicate 

 a geological age probably near the base of the Uralian. 



Northern Territory. — In the Port Keats bore between 

 the Victoria River and Darwin in Northern Territory of 

 Australia marine " Permo-Oarboniferous" strata overlie 

 dark shales containing Glossopteris. In addition to many 

 species also met with at the Irwin area one finds in this 

 marine fauna the genus Dybowskiella (D. Oeei Eth. fil.) 

 which ranges from Uralian to the top of the Upper Pro- 

 ductus limestone of the Salt Range. Dybowskiella (Pistu- 

 lipora) occurs also in the Guadalupian Series of Texas. 



With the kind collaboration of Mr. W. S. Dun, Palaeon- 

 tologist to the Geological Survey of New South Wales and 

 University Lecturer in Palaeontology, the following table 

 of Irwin River etc. fossils, largely taken from Ludwig 

 Glauert's paper (op. cit.) has been prepared: —
