ZONITES. Gay 
This is the largest of the English Zonites. It is 
common everywhere in damp cellars, under stones 
and logs. 
Var. I. complanata. Rather smaller, spire very flat. 
Var. II. albida. White or colourless. 
Var. III. compacta. Spire more raised, whorls 
more convex. 
2. Z. aALLIARIUS (smelling of garlic). 
More convex above, though less so below, than Z. cel- 
larius; whorls five, the last not so large in proportion as 
that of the last species; spire slightly produced; mouth 
narrow; wmbilicus rather wider in proportion than that of 
the last species; diameter a quarter of an inch. 
Z. alliarius is rather more local than Z. cellarius, 
though equally distributed. It has a powerful odour 
of garlic, but this is not a certain mark of identity, 
as other species have the same peculiarity. In the 
north of Ireland, near Coleraine, the variety is very 
abundant under stones, but I have rarely come across 
the typical form in that district. 
The umbilicus is wider in proportion to the size of 
the shell than that of the last species, and the spire is 
more produced. 
Var. viridula. Greenish white.
