made by Mr. Clement Reid/ who regarded the beds as Older Plio- 

 cene of Coralline Crag age, and equivalent to the Lower Crag or 

 Diestian of 15elgium. He recognised that the St. Erth beds were of 

 similar age and not newer. Speaking of the Lenham moUusca, he 

 stated that Ana dihtvii was new to England, and thai Plenrotoma 

 consohrinal Viwd P. jouanneti} were species belonging to the Upper 

 Miocene of the continent. His list of determinations, endorsed by 

 Messrs, Sharman and E. T. Newton, included i6 Gastropods, 21 

 Pelecypods, and i Brachiopod. 



Four years later fuller particulars of the Lenham deposits were 

 published by the same author- in a memoir on the British Pliocenes. 

 They were alluded to as occurring in pipes of the Chalk formation, 

 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 moUusca it was stated that such 

 southern genera as Ficula (^Fyrula), Xenophora {Flwrus), Triton, and 

 Aviaila, occurring m association with a profusion of Area dihtvii, 

 Cardiuvi papillostim, and some south European extinct species of 

 Fieurotoma 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, i Scaphopoda, 36 

 Pelecypoda, and i Brachiopoda, as follows : —
