(minimum–average–maximum). Taking into account that most of the shells had the first whorls eroded, we could observe at most 5 whorls in the better preserved shells, with a bit over 4 whorls remaining in most specimens. Colour pale tan; earlier whorls slightly paler, showing indistinct spiral bands. Spire short, decollate, about two-fifths of total height; spire angle a bit less than 45°. Protoconch and early whorls eroded. Teleoconch smooth and slightly glossy, except for fine, irregular axial growth lines crossed by spiral sculpture of very fine, barely visible grooves; grooves cover almost entire exterior surface, coarsest and most noticeable on base. Last whorl large, about three-fourths of shell height, slightly convex, angulated near the base, concave below; maximum width at about one third from anterior end. Aperture prosocline, oval, slightly rectangular, posteriorly acuminate; aperture height slightly more than half of shell height. Parietal callus slightly thickened, concave. Outer lip sharp, simple, outline weakly convex, weakly concave over upper third, then swinging forwards weakly to suture; about 8 to 12 lirae inside outer lip; columella without denticles, callous. Siphonal canal short, very wide, anteriorly with rounded siphonal aperture.
