Shell of moderate to large size, 14 - 78 mm., fusitorm-biconic, with medially angulate to
subangulatc turreted whorls, sculptured with closely spaced regular, narrowly crested axial folds, crossed by dense spiral cords and threads. Body-whorl slowly tapered to a moderately long slightly flexed unnotched anterior canal. Sinus weak, a broad shallow concavity, occupying most of the shoulder slope. Protoconch regularly conic of 3 - 5 almost smooth whorls. Operculum small, thin, corncous, ovate, with a subterminal nucleus that curves inward towards the columclia. Radula, a pair of simple wishbone-type marginals; the basal limbs bridged by a thin plate Range — typically, New
Zealand, Eocene to lower Pliocene. Recent, species from deep-water, 100-1788 metres,
Gulf of Aden to Japan; also questionably from off S. W. Australia in 1950 fathoms.
