Figure Perhaps this ver^ abundant and somewhat handsonre shell is as familiar as any of our British species, for it is the largest of the Helix family, with the exception of the very local Helix pomatia, and is moreover well known as a destructive gardener. In form it is rather subglobose, has from four to four and a half convolutions, with a blunt apex. Aperture somewhat rounded. Peristome snowy-white, spread out, and reflected. Olive-coloured, with in general four dark-brown bands. The shell has a rough surface, and although apparently strong, is nevertheless very fragile and thin. The usual diameter is an inch and a half. The colour of the animal is a greyish green. Helix aspersa is very sensitive to cold, closing its aperture in a similar manner to Helix nemoralis, on the first approach of frost. When induced to wake up and crawl about with the occasionally mild days of March, in will again become dormant on the return of frosty Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Lowe, E.
