Acmaturris is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Mangeliidae.^[1]

Description

(Original description) The medium-sized shell is slender or moderately slender. The protoconch is broad-tipped, consisting of about 2½ whorls, the last one sculptured with curved, protractive, axial riblets that may be swollen on a peripheral keel. The aperture is long and moderately narrow. The anterior canal is short and unemarginate. The outer lip is strongly varicose, the edge frilled. The anal notch is moderately deep and is broadly rounded. The parietal callus thickened the adjoining notch. The sculpture consists of narrow axial ribs and of strong spiral threads, and also of microscopic frosted spiral threads. ^[2]
