Glossy Glass Snail - Oxychilus navarricus

    Alternative names
    Oxychilus helveticus

    A medium-sized (8 to 10 mm) glossy brown snail with a slightly raised spire, 5 flattened whorls and with sutures slightly deeper than those of O. cellarius. The body is blue-grey with jet-black mantle edge - that can be seen as a dark band at the front edge of the shell. Sometimes emits a faint garlic smell when disturbed but not as strongly as the smaller Garlic Snail.

    Similar Species

    O. alliarius (Garlic Snail) is smaller: 6-8mm but also has a slightly raised spire.

    O. cellarius can be a little larger but overlaps in size, however it is very flat and lacks the slightly raised spire and the black mantle..

    Identification difficulty
    ID guidance
    • the black mantle is visible through the transparent shell as a dark band just above the mouth
    • glossy brown
    • a slightly raised spire
