544 B. BuUen Newton — Shells from Raised Beaches, Red Sea. 



Pliocene periods. It may have been shifted and incorporated in 

 glacial drift, and afterwards dislodged and transported by river-ice, 

 and thus transferred to the vi^ide-spreading gravels of tlae Thames 

 Valley. It is, however, impossible to speak precisely of its past 

 history. The fact of its occurrence is interesting, as Mr. Whitaker 

 has remarked that such blocks "occur somewhat rarely in our Eiver 

 Gravel." An example fully three feet across was, however, noticed 

 by Mr. J. Allen Brown at Alperton, in the Brent Valley, and other 

 records have been published.' 



The specimen to which attention is now directed was observed by 

 Colonel C. K. Bushe, F.G.S., and he lost no time in securing it and- 

 in presenting it to the British Museum of Natural History, Cromwell 

 Eoad, where it will be preserved and placed in the Garden on the 

 eastern side near the Fossil Tree from Craigleith, Edinburgh, and 

 not very far from the spot where it was discovered in the Gravel.
