and H. hortensis called vesicula miiltifida by M. 
Cuvier, in his dissection of Helix Pomatia, and fur- 
ther observed that this name for the organ gives 
an erroneous impression, as in several of the Helices 
it is simply forked, and in others doubly forked, and 
rarely many-cut, as it is in the edible snail. 
Helix hortensis has been introduced into the 
United States, where it is observed that, unlike the 
American Helices, they are not found burrowing 
under stones and decayed leaves, but on the ground, 
and crawling up the stems of plants. {Gould^ Mass,

The animal of this species differs from either Helix 
hortensis or H. nemoralis^ in the form of the vesicula 
multijida^ as well as in the colour of the mouth of 
the shell. In all its characters it is intermediate 
between these two species ; but yet I do not think 
there is any reason to believe that it is a mule, or 
that it unites them into one species. This species 
does not seem to be so variable in its colour as either 
of its allies. The jaw is strong, costated, and toothed.
