Macgintiella Olsson, 1956

"Shell small, bullet-shaped with a low, conic spire, the body-whorl large, subelliptical. Parietal callus strong, extending past the end of the aperture to the suture, thickening the surface of the spire-whorls. Pillar structure much as in Olivella s. s., consisting of a large, plaited lower portion followed by small denticles or lirations along the parietal wall, the inner side of the pillar wall deeply excavated. Outer lip thin, passing well above the end of aperture, its junction with the body-whorl forming a long, narrow commissure joining the grooved suture above. Operculum chitinous. Radula: rachidian tooth inversely hat-shaped, with a deep, central convex base, the sides narrowed and lid-like, the outer or cutting margin concave with numerous, small, single or dooble-rooted cusps, of nearly equal strength along it. Laterals are solid, hooked, uncinates with revurved tips and notched base; basal plate rectangular.".
