in the Ootatoor beds, several representatives both of older and newer depo- 

 sits than European Gault, ranging from the lower Neocomian to the 

 white chalk, and what weight must be attached to these respectively in 

 any attempt to parallelize our Indian deposits with those of the Euro- 

 pean series, is a point upon which it would be premature at present to 

 offer any opinion. 



The remaining classes of the Mollusca, the Gasteropoda, Conchifera, 

 and Brachiopoda, are all well represented, as will 

 be seen by the following provisional generic list, 

 drawn up principally from field notes* Those, the species of which are 

 numerous, are marked with an Asterisk, a great abundance of individuals 

 is noted by the i*.

* For this I am in great part indebted to a field list drawn up by my colleague Mr. C. M, 

 Oldham, who devoted himself principally to the collection of fossils. For its correctness 1 am 

 myself responsible.
