as being best developed in the Sattavedu hills, the sandstones 

 in which yielded the only fossil plants found in the upper 

 group. The division is based solely on the petrological 

 dissimilarity of the rocks. The Trichinopoly members 

 of the Upper Grondwana system were thought to be 

 fresh water deposits, but when examining the Sriper- 

 matur area the author found several beds of shale, in which 

 the plant remains were directly associated with marine shells 

 of the genera Leda, Yoldia, Tellina, Psammobia, Lima and 

 Pecten, &c, all thin-shelled forms whose modern representa- 

 tives live in moderately shallow water, say 8 to 10 fathoms, 

 with a sandy bottom. Dr. Stoliczka, by whom they were 

 examined, considered them to have resemblances to the 

 Trichinopoly cretaceous species, though none were identical. 

 A few small ammonites belonged to the Dentati group, but 

 they were not well enough preserved for identification. 



The fossils plants obtained in the Sripermatur beds have 

 been worked out by Dr. Feistmantel, the present Palaeontolo- 

 gist to the Survey, and published in the Palceontologia Indica. 19
