INTRODUCTION. » 



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., Pfeiffer, 48. t. 2. 



f. 3. 

 Helicolimax elongata Fir. Moll. t. 9. f. 1. 



Inhab. France. 



Introduced by Mr. Jeffreys, who appears to have 

 mistaken one of the varieties of V. pellucida for this 

 shell. 



2. Helicophanta brevipes Fer. 



Helix brevipes Drap. 119. t. 8. f. 30. 33., Turton, 

 Mail. ed. 1. 65. {f. 50. ?), Rossm. Icon. t. 2. f. 39. 

 A native of the south of Europe. 

 Introduced by Dr. Turton, who afterwards 

 thought he might have mistaken a young spe- 

 cimen of Vitrina for it ; his account is chiefly taken 

 from Draparnaud's work. The figure has not the 

 slightest resemblance to the shell, but is probably 

 Helix radiatula ? According to Michaud, it is not 

 found even in France. 



3. Helix elegans Gmelin. 3642. 

 Trochus terrestris Pennant. 



Carocolla elegans Lam., Kenyon, M. N. Hist. 



A native of Italy, and the south of France. 



M. Ferussac observes (Journ. Phys. 1820, 302.) 

 that this species is not found in France to the north 

 of Montpelier. It was said to have been found in 

 Cumberland, by Mr. Hudson the botanist. 



4. Helix explanata Miiller, Verm. ii. 26. 

 Helix albella Drap. not Linn. 

 Carocolla albella Lam., Kenyon.
