Helix aspersa, Miiller. — Generally distributed. Mr. J. W. 

 Lewis Abbott's discovery of a number of very large shells (repre- 

 sented both by whole and broken ones) under about three feet 

 of midden material in primeval refuse-heaps at Hastings affords 

 presumptive evidence that it was an article of food in prehistoric 

 times. Mr. J. P. Johnson has recorded it from a neolithic rain- 

 wash at Brighton. Mr. E. Miller Christy found, in 1878, 

 " assuredly pre-Eoman specimens in association with Clausilia 

 rolphii, Cyclostoma elegans, and Helix nemoralis, buried beneath 

 the loose earth, rilling up the pits within the Eoman Camp at 

 Cissbury." Mr. Ernest Eobinson found (1907) hundreds of 

 shells between the large flints in some of the prehistoric pits in 

 the neighbourhood of Saddlescombe. He came to the conclusion 

 that tbey reached those positions when hybernating. Mr. 

 J. W. L. Abbott found albino specimens with shells of normal 

 coloration (a rare condition) in St. Margaret's Eoad, St. Leonards- 

 on-Sea. Small forms have been taken by Mr. C. H. Morris at 

 Lewes, by Mr. E. M. Christy at Brighton, and by Mr. B. M. 

 Oakshott at Worthing.
