Abstract
Summary: New field evidence of the Clacton channel deposits i3 recorded. A general revision of the non-marine mollusca by the late A. S. Kennard and Mr. C. P. Castell points to the same invasion of Rhenish species that Kennard found in the middle of the Swanscombe sequence. The marine mollusca of the estuarine stage include nothing to distinguish them from the Holocene, although the rest of the biotope points to the mid-Pleistocene. The erratic rocks are traced back by Mr. D. F. W. Baden-Powell to a stream of proto-Thames material from the west passing through mid-Essex to the gravel cliffs at Holland-on-Sea and Clacton. A few remains of Microtinae have been examined by Mr. M. A. C. Hinton and these tentatively suggest close comparison with Grays. The mammalian remains are not described in detail, but the finding of the remains of the food of Rhinoceros in the crevices of the molars is recorded. The Clacton Stage is associated closely with the Early Taplow brickearth of Grays-Thurrock, and equally with the middle part of the Swanscombe sequence.
