UPPER GONIfWANA SEEIES. 73 



These Belemnites are the only South Indian representatives of the 

 genus that have been collected outside of the cretaceous areas in Trichi- 

 nopoly and south-west districts. Not the faintest trace of plant-remains 

 accompanied the shells. 



Unconnected with any of the rocks named in the list descriptive of 

 the Budavada section is part of a large Nautilus that 



Nautilus. 



I picked up loose in the fields about three-quarters 

 of a mile east-by-south of Budavada village This specimen, which shows 

 part of the body chamber of a good-sized individual, cannot be referred 

 to any of the known rocks of that locality, and is unfortunately too 

 fragmentary to admit of satisfactory specific determination. A long and 

 careful search failed to throw any light on the origin of this interest- 

 ing specimen, the only representative as yet of the genus Nautilus in 

 the Rajmahal beds of the Peninsula. 



The Pavulur sandstones Nos. 7, 8, and 9 of the section form, as there 



shown, a small plateau approximately circular in 



Pavulur plateau. 



shape and about a mile and a quarter in diameter. 



The thickness of this Pavulur group is small, but all the members not 

 occurring together in any one section, the total thickness is doubtful. 

 The beds roll about a little at low angles, but are here and there 

 quite horizontal. The hard dark-coloured slightly shelly bed No. 8 is 

 from 2 to 3 1 feet thick. The underlying drab sandstone was not 

 pierced by any of the pits open at the time of my visit, but is probably 

 not more than 5 or 6 feet thick, according to the quarrymen and the 

 owner of the ground, which agrees with the estimate I formed independ- 

 ently. Some of the blocks of the dark sandstone, of irregular shape, and 

 covered externally with a brown weathering crust, have at the first 

 glance a singularly trappean look, and I was for a moment startled by 

 the idea that I had come upon a bedded trap. 



The drab sandstone No. 7 contains some intercalated flatly lenticular 

 masses of hard dark sandstone, similar to that in the overlying bed. The 

 latter dips gently eastward near the village of Pavulur, and is here 

 apparently overlaid by the friable reddish-brown sandstone No. 9, which
