Description
The shell is medium-sized (25–30 mm width), globose in shape with 4 to 5 rapidly expanding whorls. The shell is translucent so that the speckled black mantle shows clearly through the shell of the living animal. The shell is usually thick and strong, but in acidic environments it can be thin and fragile. The body whorl is increasing in size more than those of spire. There is no umbilicus. The shell is sculptured with fairly regular, strong, curved axial ribs. Fresh specimens are with rich dark tan covering, sometimes with light brown axial streaks. Older specimens are yellowish brown. The lip and columella is white.
Individuals of Zachrysia provisoria use love darts during mating.
