Another interesting discovery made by Mr. King in the 

 Grodavari country was that of a marine formation of sand- 

 stones with calcareous beds at top in which marine fossils 

 abound. Only one form, a very abundant Turritella, has 

 been identified with T. dispassa from the.Arialur cretaceous 

 beds of the south ; and only one fossil, Carditd variabilis, 

 occurs in the overlying intertrappen beds. The exact posi- 

 tion of these Dudukur and Pangadi infratrappeans is doubt- 

 ful, but the balance of evidence is in favor of regarding them 

 as cretaceous or intermediate between that and lower Eocene. 

 Many of these fossils are still awaiting determination. 



The inter-trappean beds which overly the infratrappean 

 with the intervention of a flow of Deccan trap of from 30 

 to 100 feet thick have long been known to occur on both 

 sides of the Godavari, at Pangadi and Kateru. They were 

 discovered by General Culien and Dr. Benza, collected chiefly 

 by Lieutenant Stoddart and Sir Walter Elliott, and described 

 and figured by the Eev. S. Hislop. 31 The shells, which
