LAND AND FBESHWATER MOLLUSC A OF SUSSEX, 349 



renee of this species in Sussex in his ' Pinax rerum naturalium 

 Britannicarum,' 1667 ; the reference is the earliest that I have 

 discovered concerning the molluscan fauna of the county. We 

 have evidence that it was esteemed as an article of diet by the 

 primeval inhabitants of the Downs ; the Eev. W. A. Shaw 

 informs me that shells were found in British middens on Stoke 

 Clump in 1910. 



It is doubtful whether it exists in Sussex at the present time. 

 Allusion has already been made to attempts at reintroduction by 

 zealous conchologists (pp. 178, 179). 



H. nemoralis, Linne\ — Generally distributed. Mr. F. Dixon 

 has recorded it from post-Pliocene beds at Bracklesham Bay, the 

 Bev. W. A. Shaw from a post-Pliocene deposit near West Stoke, 

 and Mr. J. P. Johnson has found it in Pleistocene beds exposed 

 at low tide on the foreshore at West Wittering. Holocene records 

 are the " mud deposit " at Selsey, 1891, Alfred Bell ; beneath 

 loose earth filling up the pits in the ancient Boman camp at 

 Cissbury, Mount Caburn, and Seaford (General Pitt Bivers) ; 

 cultivation balks on the Downs near Brighton (H. Toms) ; and 

 near the base of a neolithic chalky rain-wash overlying the 

 Palseolithic rubble-drift to the east of Brighton (J. P. Johnson). 

 (Its association with archaeological remains has been commented 

 upon in the first part of this paper, pp. 179-181.) 



Large shells (var. major) have been taken by Messrs. Jenner 

 and Morris at Lewes, and minor forms have been taken in the 

 same neighbourhood by the former observer.
