Description: Shell medium sized, sinistral. Protoconch unknown. Teleoconch whorls straight sided with 4 spirals; 1-3 beaded  cords of coalesced nodules, edges sharp with overhanging sides, commencing  immediately after protoconch. Spiral 4 a very fine thread slightly exposed on all whorls, fully exposed on last whorl. Another 2 spirals on base (numbered 5 and 6), smooth, spiral 6 very faint. Interspaces between spirals with numerous axial costae much weaker than spirals, 32-40 on penultimate whorl. Outer lip of aperture flared, anterior siphonal canal short and slightly upturned. Colour pale pink or yellowish brown.

Distribution: Endemic to Australia: Capricorn Group, Qld, southwards to Sydney, NSW.

Habitat: Known from beach washup and one lot from 31 m depth. Rare. Only 6 lots known.
