HELICID^. 
Inhab. woods and hedges, on chalky soil and oolite 
formations in the southern and midland counties of 
England. 
Animal warty, pale greyish brown, beneath grey ; 
tentacles long, paler ; foot dilated, netted with im- 
pressed lines, beneath ashy (^Sturm^ F. t. 21.). The 
jaw is strong, with ribs on the front and teeth on the 
edges. 
Shell two inches long and as much high, rather 
solid, with the body volution extremely large and in- 
flated, the others very little rounded, strongly striate 
across, and minutely so in a spiral direction ; colour 
whitish, with the bands hardly visible, or pale tawny, 
with usually four darker bands, two of them pene- 
trating the aperture at the pillar; aperture some- 
what orbicular, longer than broad, with the margin 
thick, and reflected at the pillar so as in general to 
cover the umbilicus, or nearly so ; the inside of a 
pale violet brown. 
The shell varies greatly: 1. in size; 2. in the 
intensity of the bands; 3. in the ventricoseness, 
and 4. in the height of the spire. Monstrosities are 
sometimes found with the spire depressed, when it is 
Helix pomana of Muller ; and others with the spire 
produced and conical, when it is H scalaris of the 
same author. 5. It is sometimes reversed; and very 
rarely the whorls are separated one from the other 
like a cornucopia. (See Feruss. Hist t. 21. f. 7, 8, 
The eggs are globular, covered with a white, 
opaque coriaceous skin, and are about two and a half 
lines in diameter. They are figured by Pfeiffer (t. 7.
