Type of larval development: planktotrophic, inferred from multispiral protoconch.

Nightingale Island; Brazil; Great Meteor seamount, Hyères, Irving, Plato, Tyro and Atlantis seamount; Azores, moderately common in 280 m-1180 m. 

European waters (ERMS scope)

Shell fusiform, rather solid, up to 20 mm high. Protoconch of 3.3 whorls, with latge pustulose protoconch 1 and sculpture formed by two spiral keels and small, interrupted axial riblets on protoconch 2. Teleoconch of 7-8 whorls, rather convex with deep suture. Sculpture of strong, high, slightly prosocline axial folds developed throughout and hardly fainting on the last part of the body whorl; spiral sculpture of numerous, squamose spiral cordlets overruning the folds and alternating stronger and lesser. Body whorl making up ca. 70% of total height, with regularly rounded profile towards the periphery, distinclly constricted around the siphonal canal whic is marked by a prominent fasciole. Aperture rounded, outer lip somewhat thickened internally with small denticles reaching far inside, columellar and parietal edge bordered by a narrow, appressed callus. Colour whitish, tending to ivory.
