Oxystele tigrina, common name the tiger top shell, is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.[1]

The size of an adult shell varies between 25 mm and 43 mm. The more or less elevated, imperforate shell has a conoidal shape. It is lusterless blackish or purplish, unicolored or with a few scattered white dots, or yellowish flexiious lines. The yellow or whitish, apical whorls are eroded. The about 6 whorls are spirally coarsely but obsoletely lirate. The large aperture lis oblique with a black border and is silvery within. The simple columella is white or yellowish, bordered by a dull purplish streak. The parietal wall is usually covered by a thin silvery callus.[2]
