Biology Type of larval development: planktotrophic, inferred from multispiral protoconch. [details] Diagnosis Shell up to 20 mm high, solid, fusiform. Protoconch of ca. 3.5 whorls, with sculpture formed by two spiral keels and small, interrupted axial riblets. Teleoconch of little more than 5 whorls, with conical spire. Spire whorls convex, strongly keeled, with incised sutures; body whorl convex in the area bordering abapically the keel, then strongly constricted towards the siphonal canal. Sculpture on the teleoconch whorls consisting of closely set spiral cords with densely packed imbricate scales, and orthocline axial folds; cords even in size except for a larger one on the shoulder keel. Siphonal canal long, twisted, open, with an imbricate fasciole enclosing a narrow umbilical chink.
Aperture gradually tapering towards siphonal canal, rounded adapically; outer lip simple, with smooth edge or slightly notched between cord terminations, forming a shallow inwards embayment on the adapical side, orthocline. Ground colour ivory white, inside the aperture bright white. [details] Distribution Only known with certainty from Great Meteor, Hyères, Irving and Atlantis seamounts, moderately common in 310-640 m; shells also collected on Lion seamount.
