The animal, stretched out eight to twelve centimeters, is usually colored live yellow and has black or brown spots.

The lateral furrows begin together at a visible point on the front edge of the coat.

The same smack half-stretched out from behind. The lateral furrows arise very closely from the front edge of the mantle.

The bowl is small and flat, six to seven millimeters long and four millimeters wide. It has an almost triangular shape and is flattened at the top, sometimes concave. The upper end of the central spindle of the snail shell (columella) is sharply truncated. The periostracum is thicker and less abraded than that of the gray-yellow backpack snail ( Testacella haliotidea ).

It occurs in western France, England and Ireland as well as in Spain, Croatia, Italy, Sicily and the Canary Islands, especially in gardens and parks. The yellow backpack snail stays in the ground at depths of ten to thirty centimeters during the day and comes to the surface in the evening.
