Margarella violacea is a species of small sea snail, a marine gastropod mollusk in the family Calliostomatidae, the top snails. [1]
The animal is pale beige in color and has a pair of cephalic tentacles. [1] The eyes are large and black. [1] The shell is small and wider than it is high. [1] The size of an adult shell varies between 7 mm and 13.5 mm, but can be up to 8.4 mm in height and 9.9 mm in diameter. [1] The purplish-pink shell is imperforate, orbicular-conical, thin and smooth, and is covered in fine pink or dark pink spiral lines. [1] There are four swollen whorls. The suture is scarcely impressed. The rounded-quadrangular aperture is angular above, and subangular at the base of slightly thickened and arcuate columella. The umbilico-columellar tract is excavated. [1]
