HELIX. 
Ill 
Some shells change the character of their marking 
during the life of the snail ; thus some that have all 
the bands separate in the young state^ have one or 
more bands united together in the older or more 
recently formed part of the shell, and vice versa. 
Sometimes, instead of the bands being darker than 
the ground colour of the shell, they are paler and 
more transparent. 
The ground colour of the shell also varies from 
very pale whitish to opaque white, yellow and yel- 
lowish red to dark red or brown. 
M. Moquin Tandon divides the three specimens 
into varieties according to the bands and colours, 
naming them after conchologists, and in this manner 
indicates no less than 77 named kinds of H. nemoralis 
and 46 of H. liortensis ! 
b. Shell suhglobose, solid^ banded; 'peristome rather 
thickened^ rejiexed ; axis perforated ; epiphragm 
calcareous^ with several membranaceous ones 
within it. (Pomatia Gesner.^
