Landenian.—The Landenian is represented by the Thanet Sands and Woolwich and Reading Beds. The former seem to correspond to the two lower zones of the French Landenian, whilst the marine Bottom Bed of the Woolwich Series corresponds to the zone of Cyprina scutellaria. The present writer. has given reasons for believing the pebble-bed separating the two to be due to a movement of uplift in the Wealden area.1 In the east of the London district the marine Bottom Bed passes up into clays and marls crowded with estuarine fossils (Woolwich Beds); to the west into unfossiliferous mottled clays and fluviatile sands (Reading Beds). The extensive transgression at the time of the zone of Cyprina scutellaria is noticeable in the London Basin as it is in the Paris and Hampshire Basins.
