HELICID^. 
Mr. Alder notices this species in his catalogue of 
Newcastle shells : — A curious pale brown variety 
of this species 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 muU 
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 with its rosy mouth ; and 
more lately M. Deshayes proposes to consider Helix 
nemoralis^ H, hortensis^ H, hybrida, H, sylvatica^ 
and H, austriaca, as all varieties of the same species.
