The base of the shell is pale, usually cream in color, and defined by brown or chestnut blotches that radiate outwards along the whorls.

A picta was long thought to be endemic to one cove on the edge of the Cumberland Plateau, near the town of Sherwood, Tennessee along the Crow Creek drainage.

In 2018, a land grant to the Sherwood Forest, part of South Cumberland State Park, included one-third of the snail's known range, and is now a protected area.

[4] Threats to the species include residential development, which can alter the habitat indirectly by adding polluted surface runoff into waterways.

Logging also removes forest cover; the snail can apparently tolerate some degree of deforestation, but the long-term impacts on its survival are not yet known.
