CARBONIFEROUS AND PERMO- CARBONIFEROUS ROCKS, N.S.W. 261 



material had been carried into the sea during a period of 

 flood. It has not been possible to determine the exact 

 horizon in the Lower Carboniferous Series of this plant- 

 bearing bed, but marine strata occur both above and below 

 it, and it unquestionably belongs to the Lower Carbonifer- 

 ous epoch. 



The fossil plants found in the Burindi Beds include the 

 following: — 

 Lycopods — Lepidodendron veltheimianum Feist. 



,, sp. (cf.L. dichotomum of Europe, 



or L. scutatum of America 

 Ulodendron 



Cyelostigma austrcde Feist. 

 Equise tales — Archceocalamites. 

 Coniferales — Pitys. 



Of these plants Lepidodendron preponderates and appar- 

 ently grew to a fair size. Pitys grew to quite a large tree, 

 as quite large stumps were found by Prof. T. W. E. David 

 at Hofman's Farm. The absence of fern fronds in this 

 flora is no doubt due to the fact that the plants are found 

 in marine strata and have been drifted probably from con- 

 siderable distances, conditions which would not be favour- 

 able for the preservation of delicate fern fronds. 



B. The Kuttung Series. 



The Wcdlarobba Conglomerates. — These occur at the 

 base of the Kuttung Series, they follow the Hilldale Tuffs 

 (the topmost beds of the lower series) without any angular 

 unconformity, in fact the tuffs merge upwards gradually 

 into the conglomerates and similar tuffs occur interstratified 

 with the conglomerates themselves. 



These conglomerates have an extraordinary development 

 in this district; at Wallarobba they have a thickness, 

 including the interstratified tuffs and tuffaceous sandstones, 

 of about 1300 feet, the bulk of this material being con-
