Roman Snail, Helix pomatia (Mollusca: Helicidae), in Canada

Abstract

Populations of Roman Snail, Helix pomatia, a large European land snail, are reported for the first time in Canada from disturbed habitats in two distant locations: Sarnia, Ontario and Montrose, British Columbia. As Roman Snail is an edible species subject to international commercial trade, its deliberate, but illegal, introduction into Canada and intentional or unintentional releases are possible sources of these populations.
