Cypridea tuberculata, Sow., sp. -valdensis, Sow., sp. Melanopsis attenuata, Sow., sp. tricarinata, Sow., sp. Cyrena media, Sow., sp. membranacea, Sow., sp. Cardium ?, sp. Ostrea, sp. These beds have been regarded by some geologists as the greatly attenuated representative of the Weald Clay.

This series of beds, which is about 153 feet thick, greatly resembles, in many of its characters, portions of the Bagshot series and of the Northampton Sand. It was in these beds that Professor John Phillips obtained the fossil fruit which he described before this Society in 1858 *.

The oyster-beds cannot be conveniently examined in situ, as they are exposed in a very inaccessible part of the cliff ; but facilities for collecting their fossils are afforded by the great slipped masses which lie lower down and nearer the shore.
