The white-lipped snail or garden banded snail, scientific name Cepaea hortensis, is a medium-sized species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Helicidae. It is a close relative of the Grove Snail.
The white-lipped banded snail has a glossy, smooth shell, which is typically yellow in colour but may be pink, brown or red, with up to 5 variable spiral dark bands and an obvious white lip around the aperture. Occasionally a dark-lipped form of this species may arise, which makes identification more complicated. It is similar in appearance to the brown-lipped banded snail (Cepaea nemoralis), but it has a thinner shell, with more rounded whorls. The body of the snail is usually greenish-grey becoming yellow towards the rear .(LINK)
