Shell smooth, except for axial growth lines and 0 basal lirae (visible only under high magnification). The brown axial lines, on a light brown ground, are variable in width, even on the same shell; some of them may even be bifurcate. Therefore it is not possible to distinguish two species (as did Viader) on the grounds of the brown lines being less numerous or 'larger and wider'. Protoconch of 1,5 smooth, dark brown whorls. Length varies from 2,6 to 3,5 m. Empty shells found in hand-dredged sand from 12 to 70 m. Rare.
Distribution: Réunion and Mauritius.
