Surface dull, very minutely but sharply striated in the direction of growth lines, a strong lens showing much more minute and superficial, dense, spiral striation, the apical whorls spirally lirate.

Whorls 6, the first turned in, the rest rather rapidly and regularly increasing, moderately convex, the last becoming free at the aperture, compressed behind the outer lip, the trench there impressed by five pits; base pinched into an acute, produced keel; and behinid the columellar lip there are two pits and a deep axial pit, with another shallow pit behind the elevated parietal wall.

Aperture slightly oblique, narrow, irregularly oblong, obstructed by eight pliciform teeth and a strong, deep-seated columellar lamina; peristome continuous, white, reflexed through-out, the outer lip with two large teeth situated like those in O. odontostomus, witlh smaller teeth betweein themn and an the upper one; the teeth llpon the columellar and parietal margins corresponding in position with those of O. odontostomus.”
