l88 THE DISPERSAL OF SHELLS. 



they were probably devoured by hedgehogs. About 

 1868-9 Mr. W. Jeffery is said to have turned out thirty 

 or forty Surrey specimens partly in his garden at 

 Ratham, Chichester, and partly on a bank of light soil 

 near, but of those on the bank nothing more was seen, 

 and in the garden — though they seemed to do pretty 

 well for a time, producing, at least, one brood of young, 

 some of which attained full size — the original stock had 

 all vanished previously to 1874, and during the prece- 

 ding summer only two young ones had been seen.' 



Mr. Jeffreys, as he stated in 1862, twice endeavoured, 

 at different times of the year, with an interval of nearly 

 three years between each attempt, to colonize the 

 beautiful and local Helix pisaiia on the sandhills near 

 Swansea ; a basketful of living specimens from the 

 well-known habitat at Tenby, only about thirty miles 

 distant, were spread over different parts of the Burrows, 

 where the soil and herbage appeared to be the same as 

 at Tenby, a more easterly aspect at Swansea being the 

 only noticeable difference in the localities, but, as 

 Jeffreys added, although they seemed " at first to thrive 

 tolerably well in the new locality, they did not multiply, 

 and the birds soon ate up the immigrants." ^ He was 

 mistaken, however, in supposing that his endeavours 

 had been altogether unsuccessful, for on searching the 

 sandhills in 1874, Mr. Rimmer, to his astonishment, 

 found the shell living there in countless numbers and of
