Discrssrox. 



Sir Thomas Holland said that this precise description of a 

 new occurrence of Miocene deposits would stimulate the Geological 

 Survey of India to renewed search for relics of the Miocene 

 trespass on the peninsula of India. Miocene fossils were found 

 by Mr. Gr. H. Tipper twenty years ago on the Andaman Islands, 

 and preliminary descriptions of them by Mr. E. W. Vredenburg 

 indicated Burdigalian affinities. He asked whether Dr. Davies 

 had been able to compare the Andaman records with the apparently 

 younger Miocene fauna found by Mr. Wayland. 



Dr. A. MoitEEr Davies, in reply, said that he had overlooked 

 the record of Miocene in the Andaman Islands, and was glad to 

 have his attention called to it.
