192 THE DISPERSAL OF SHELLS. 



H. ericctoruuL had increased to a considerable extent ; 

 H. aspersa^ also, had survived and had become so 

 numerous in his garden that hundreds had been trans- 

 planted to different parts of the East Sutherlandshire 

 coast during the preceding summer. H. cantiana and 

 H. rufescens had done well, and Clausilia parviila was 

 still alive, as also in all probability were CI. lamiiiata and 

 Cyclostoma elegans. Living specimens of Clausilia bipli- 

 cata from the banks of the Thames, Clausilia solida 

 from France, and Cochlicopa t7'ide7is and Helix poniatia 

 had also been turned out in small numbers. A number 

 of Clausilia laminata and Clausilia rolpJiii from Buriton, 

 Hants, were once turned out by the Rev. J. McMurtrie 

 in a glen at North Berwick, Haddingtonshire, but, as 

 was stated a few years afterwards, *^ it is not likely they 

 have withstood the climate." ^ Mr. G. B. Adami, it is 

 said; " has tried to introduce seventeen species of land 

 and fresh-water molluscs at Edolo, Val Camonica, from 

 other parts of Upper Italy," of which four soon disap- 

 peared, the rest surviving." A number of land-shells 

 {Helix ?, several species) from Buenos Ayres and 

 Montevideo were once turned out in a garden in York- 

 shire, and after three or four years many were re- 

 ported to be still alive and apparently healthy. It is 

 interesting to find, as the observer remarked, that the 

 creatures were able to withstand the rigour of our 

 climate ; one of the winters through which they passed
