“Coquille trochiforme, à base arrondie, aplatie et concave, mais non ombiliquée; obtusément carénée; sommet acuminé; neuf tours de spire, augmentant graduellement; arrondis et renflés près de la suture; divisés en deux portions par la fascie de la fissure; une supérieure portant des tubercules obliquement dirigés; une inférieure chargée de tubercules plus volumineux, dirigés verticalement.  Fascie de la fissure décussée par des stries concentriques et semi-circulaires.  Dépression ombilicale excavée, nacrée, irisée, entournée de sillions concentriques; ouverture semi-ovale; columelle recouverte d’une légère callosité nacrée; péristome non réfléchi, trenchant, sans nacre, obtusément anguleux, divisé profondément par la fissure.  La coquille est d’un rose pale, ornée de taches obscures, brunâtres, surtout vers le dernier tour.” (Fischer and Bernardi, 1865)

Trochiform shell, at the base round, flat and concave, but not umbilicated; obtusely keeled; acuminate summit; nine whorls of the spire, climbing gradually; rounded and inflated near the suture; divided in two portions by the fasciole of the fissure; on the top some beads are directed at an angle; a lower region of more voluminous beads are directed vertically.  Fascioles of the fissure decussate by the concentric, semi-circular striae.  The umbilical depression is excavated, nacreous, iridescent, turning from a concentric spiral; semi-oval opening; columella covered with a slight nacreous callous; peristome non-reflective, entrenched, without nacre, wide angles, sharply divided by the fissure.  The shell is pale pink, ornamented with obscure marks, brownish, mostly around the last whorl.
