CAKBONIFEROUS AND PERM0-CARBONIFER0US ROCKS, N.S.W. 323 



9i) the late Palaeozoic rocks of India. He classes all the 

 Permo-Oarboniferous strata of New South Wales from the 

 top of the Upper Marine Series to the base of the Lower 

 Marine Series as Upper Carboniferous, and the Newcastle, 

 Dempsey and Tomago beds as Permian. 



7. South Africa. — For the sequence of these beds the 

 author follows the classification by A .W. Rogers and A. L. 

 du Toit. 1 The Witteberg Series (see Plate XXX, Section 8, 

 at end of this paper) with its Lepidodendron, Sigillaria, 

 Bothrodendron and Cyclostigma would appear to be of Culm 

 age, and homotaxial partly with the Burindi Series, partly 

 with the Kuttung Series of New South Wales. 



This series passes up apparently without angular uncon- 

 formity into the overlying Dwyka Series. The lower 

 portion of the Dwyka is chiefly tillite, and the upper chiefly 

 shales. 



In the Dwyka shales of German South-west Africa, 

 Schroeder' 2 has described the occurrence of Oonularia and 

 Eurydesma globosum. The chief locality referred to is 

 Ganikobis. The occurrence of these marine fossils links up 

 the Dwyka Series with the "Speckled Sandstone " glacial 

 deposits of the Salt Range, and perhaps with the Eury- 

 desma cordatum glacial horizon of the Hunter District, 

 New South Wales. The main masses of Dwyka tillite, 

 underlying, as they do, shales containing Lepidodendron 

 australe (Upper Devonian in New South Wales) can hardly 

 be newer than Carboniferous. They are surely Pre-Greta, 

 and may in fact belong to the top of the Kuttung Series of 

 New South Wales.
