ii2 R. BULLEN NEWTON on 



questions Garde's recognition of Cardita beaumonti, a well-known Cretaceous 

 fossil from India, in the Soudan deposits. Further Molluscan forms are also 

 mentioned by Douville, such as the occurrence of longirostriform Ostreas of 

 the genus Crassostrea, at Tamaske associated with Chelonians and Halitkerium, 

 and he is of opinion that the character of the fauna generally admits of no 

 doubt as to its Eocene age. 



But without further remarks on the important question of West African 

 stratigraphy, it is thought that the very brief reference here given to a few 

 of the principal papers on the subject will be all sufficient for the purposes 

 of this report. In any case, however, the Molluscan fauna now described, 

 finds little or no analogy with any other peculiar to the immediately sur- 

 rounding regions, its relationships being restricted to the Lutetian-Bartonian 

 areas of Northern Africa, especially Egypt, the same facies extending to 

 European and British rocks, and in a probably slighter manner to the Alabama 

 Eocene beds of the United States. The same faunistic facies does not 

 apparently extend to the Indian Eocene deposits.
