A more extended scheme of the Pliocene deposits of the East of 

 England was again published by Mr. Harmer/ based on his classifica- 

 tion table of 1899. In this the Older Pliocene beds were divided 

 into : — 



Lenham Beds: Zone of An'a diluvii - Diestian.

The Coralline Crag deposits were scheduled as the basement of 

 the Newer Pliocene series of rocks, which he had formerly placed in 

 the Older Pliocene. 



Mr. W. P. D. Stebbing- next announced the discovery of some 

 molluscan remains in a patch of sand and ironstone at Netley Heath, 

 Surrey, between Dorking and Guildford, along the top Qf the North 

 Downs, at heights varying from 570 to 600 feet, O.D. The speci- 

 mens, consisting of sandstone casts, were referred to the genera 

 Cyprina ?, Alodlola, Nassa, Trochus, Cardhitn, Pectunculus, Tellina, 

 and Thracia, no specific determinations being given. The author 

 inclined to the view that these sandy deposits were a westerly exten- 

 sion of the Lenham beds near Maidstone, and those at Paddlesworth 

 north of Folkestone. 



Referring to the Lenham fossils, which Mr. E. Van den Broeck-' 

 had examined at the Museum of Practical Geology, that author was 

 of opinion that they represented a fauna of Diestian age. He noted 

 the presence of older forms corresponding to the Bolderian (Upper 

 Miocene) fauna of Belgium, and among the Box-Stones at the Ipswich 

 Museum he identified species found in the Belgium Miocene. He 

 concluded, therefore, that the Lenham beds were Diestian, and that 

 the Box-Stones corresponded with the Bolderian of Belgium, or prob- 

 ably a more recent horizon which represented the Mio-Pliocene or 

 Older Pliocene, a period slightly anterior to the Diestian. He was, 

 also, of opinion that the zones of Terebratiila grandis and Isocardia 

 cor could not be separated, but belonged alike to the Diestian divi- 

 sion of the Pliocenes.
