THE BRITISH FAUNA. 293 



such practices often overreached themselves ; for not satisfied 

 with adding to the Fauna species which, fi-oai their geogra- 

 phical distribution, might possibly be found in our island, they 

 often fixed on such tropical shells as were most easy of access, 

 without heeding that these must at once be excluded from our 

 Fauna when their true locality became known. 



Some of the species introduced, as I believe, by mistake, are 

 natives of the Continent, especially of the south of Europe. 

 Such are — 



1. Vitrina elongata. Drap. Moll. 120. Inhab. France. 



2. Helicophanta brevipes. Fer. A native of the south of 

 Europe. 



3. Helix aperta, t. 11. f. 129. A native of the south 

 of France, Bordeaux. 



A single specimen is said to have been found in Guernsey, 

 by Mr. Edward Forbes, but it has never occurred again. 



4. Helix elegans. Gmelin. 3642. A native of Italy and the 

 south of France. 



5. Helix explanata. MiUler, Verm. ii. 26. Inhab. Italy 

 and the south of France, on the shores of the Mediterranean.

 native of France and Sweden, 



7. Helix Olivieri. Ferussac, Prod. 255. Inhab. south of 

 Europe, Syria (?).
