46 CRETACEOUS ROCKS OF S. IXDIA. [PaRT II. § 1. 



It extends as far Northwards as Cullpaudy, and is tlien finally overlaj^ped 



Ly llie limestones of the Ootatoor Group. Beyond Cullpaudy I have 



myself seen no traces of plants in these beds, but in some ))eds to the 



North-east of Maravattoor, -which strongly resemble 



Plant-beds of Maravat-

informed me that he found recognizable specimens 

 of the plants which characterize the beds of Ootatoor and Terany. On 

 hearing from Dr. Oldham to this effect, I revisited them with a 

 view to ascertain their stratigraphical relations. With this object I 

 examined all the exposed sections, from where they are seen to rest on 

 the gneiss, up to beds of undoubted Ootatoor age, but without detecting 

 any unconformity or any sudden change of mineral character such as 

 might lead me to suspect the existence of distinct formations, while shales 

 lithologically similar to the above are seen close by intercalated with 

 beds indubitably of Ootatoor age. I did not find any remains of plants. 

 Under these circumstances I cannot at present regard the Maravattoor 

 beds as of the true plant-bearing group, and will treat them provisionally 

 at least as a part of the Ootatoor formation.*

 exposed, but abound in Zamias and the usual sedge-like stems and 

 leaves, and dip beneath a narrow mass of coral-reef limestone that 

 extends from the Southern corner of the large Ootatoor tank. 



The above are the only localities at which beds, undoubtedly belong- 

 ing to the plant-bearing group, are exposed. A

at the base of the Ootatoor Group, and 1 have but little doubt that it
