frequently at considerable heights above the sea, near Lenham itself 

 being found at 680 feet above sea-level. The whole of the British 

 Pliocene series were grouped into " Newer " and " Older ", the latter 

 containing the following divisions : — 



Older Pliocene. 

 St. Erth Beds. Lenham Beds. 



Coralline Crag. Box-stones. 



In connection with the Lenham Mollusca it was stated that such 

 southern genera as Ficula {Pyrula), Xenophora (Phorus), Triton, and 

 Avicula, occurring in association with a profusion of Area diluvii, 

 Cardium papillosum, and some South European extinct species of 

 Pleurotoma and Terebra, represented a fauna in favour of a southern 

 or Mediterranean origin. 



A full list of fossils from the Lenham and other Pliocene deposits 

 of England was given in tabular order, showing the distribution of 

 each species in Belgium, France, etc., the Lenham shells alone 

 including 65 species, made up of 27 Gastropoda, 1 Scaphopoda, 

 36 Pelecypoda, and 1 Brachiopoda, as follows : —
