Dillwynella is a genus of sea snails, marine gastropod mollusks in the family Skeneidae. [1]
The genus name of Dillwynella is in honour of Lewis Weston Dillwyn (1778 – 1855), who was a British porcelain manufacturer, naturalist and Whig Member of Parliament (MP).
The minute, depressed, porcellanous shell has a thin horny operculum. It consists of comparatively few whorls. The shell is imperforate, but with a depression bounded by a riblet in the umbilical rib outside of the columella. The few whorls have a thin fugacious epidermis. The outer lip is thin . The columella has no teeth, projections, or folds, passing smoothly into the anterior margin. [2]
