CATALOGUE OF THE MOLLUSC A OF SUSSEX. 179 



specimens of H. pomatia in a chalk-pit on the Downs near 

 Kingley Vale in September, 1909, but has not visited the spot 

 since. 



Instances of the introduction in ballast of Molluscs into 

 certain districts in Sussex during the construction of a railway 

 are quoted by Mr. Wallis Kew (op. cit., pp. 197-198) : — " Helix 

 virgata found plentifully on embankments between Pevensey and 

 Bexhill, where the London, Brighton and South Coast Bailway 

 runs close to the sea, was probably brought, as the Bev. S. 

 Spencer Pearce states, with the chalk forming the embankments, 

 which is believed to have come from the Eastbourne cutting, 

 some eight or nine miles away ; the same Snail, according to 

 another observer, noticed in several places on railway banks, 

 also in Sussex, ' was probably brought with chalk ' ; a colony of 

 H. cartusiana, also, known to have existed for some years at 

 Cowfold, in the same county, and now extinct, is believed to 

 have been originally introduced with chalk. H. virgata . . . 

 established in gardens now disused and weed-grown, around 

 some of the Martello Towers in the midst of the broad shingle 

 beach, which, of course, is destitute of terrestrial Molluscs, 

 between Eastbourne and Hastings, was probably introduced, Mr, 

 Pearce suggests, with the chalky soil of which the little plats 

 were formed, or it may have been carried thither with garden 

 plants." 



Association with Local Arch^ological Bemains. 

 Mr. Herbert Toms, in a paper entitled " Bough Notes on 

 Land and Marine Shells associated with Local Archaeological 

 Bemains," read before the Brighton and Hove Archaeological 

 Club in April, 1912, raises the interesting question whether 

 H. nemoralis was eaten by prehistoric peoples. He had noticed 

 large numbers of bleached shells associated with Boman and 

 British pottery in the mole-heaps covering the tops, slopes, and 

 bases of ancient cultivation balks near Brighton, on spots that 

 are now devoid of furze, and had ascertained subsequently that 

 Lt. -Colonel Pitt Bivers had noted similar shells in excavations 

 at Cissbury, Caburn, and Seaford Camps. I am indebted to 

 Mr. Toms for detailed notes concerning the shells observed at 

 these camps, and here append a summary of them.
