Physical Description

Morphology

Shells short, obese fusiform or bucciniform. Shell surface white with strong spiral ribs (about 8-10 on penultimate whorl and some 25-30 on body whorl including base) which overlie weak growth lines. Spire roundly conical, but body whorl well inflated, occupying about 50% of shell length. Aperture wide, lunate, with crenulated outer lip corresponding to spiral ribs. Columellar lip almost straight. Siphonal canal open, not twisted. No operculum present. Head with big rhynchodaeum. Toxoglossate radula teeth hollow, needle-like in shape with basal expansion. Distal tip sharp, monocuspidate with a slit.
