Shell small, elongate for genus. Surface smooth. Spire about 1/7 shell length. Suture distinct. Aperture narrower posteriorly, outer lip bent in middle. Columella with four folds. Color cream to whitish. This is a much smaller shell than locally occurring Prunum succinea; this latter also differs by having a much broader aperture that is broader anteriorly (toward the bottom of the pictures.) This is a rare find for Sanibel Island, collected by Ken Piech in early 2014.
