How to Distinguish from Similar Species: Lacuna variegata has brown chevrons instead of the white stripe spiraling down the shell, and is more common on eelgrass. L. vincta also is said to have an unusually wide aperture. The umbilicus of L. variegata is also not between 2 ridges on the columella, as it is in this species.

Comprehensive Description

provided by Invertebrates of the Salish Sea
Shells in Family Littorinidae have no siphonal notch. The interior of the shell is not pearly. An operculum is present. The height is greater than the diameter, but not several times greater. The columella has no folds or ridges. Members of subfamily Lacuninae have a slitlike umbilicus between the columella and the body whorl. Lacuna vincta has an aperture which is about half the height of the shell. The shell is tan or brown, with a broad white spiral band and a slightly glossy periostracum. In these specimens, the open umbilicus is between two distinct white longitudinal ridges on the columella. Height to 1.6 cm.
