108 HELICID^. 



Mr. Alder notices this species in his catalogue of 

 Newcastle shells : — " A curious pale brown variety 

 of this species (i/. hortensis) occurs at Stella, the lips 

 being of a paler shade of the same colour, and rarely 

 white." 



M. Deshayes believes this animal to be the mule 

 of the two species, as the name indicates ; he says 

 they are not sterile [Lam. H. ed. 2. vi. 53.). He 

 had not observed the peculiarity in the vesicula miil- 

 tifida. 



Messrs Brard and Deshayes propose to unite 

 Helix nemoralis and H. hortensis into one species. 

 M. Deshayes states that he has often seen the two 

 kinds in copulation ; that these connections he be- 

 lieves to be fertile, for in the same situation he has 

 found the Helix hyhrida Avith its rosy mouth ; and 

 more lately M. Deshayes proposes to consider Helix 

 nemoralis, H. hortensis, H. hyhrida, H. sylvatica, 

 and H. austriaca, as all varieties of the same species.
