Description edit
The fusiform shell is not umbilicate, anteriorly rostrate and obliquely folded. The shell is spirally furrowed by lirae. The aperture ends in a short siphonal canal. The simple columella is not folded. The outer lip is thin, posteriorly wide but not deeply sinuate. The shell lacks an operculum.
The enormously expanded rostrum, and the absence of eyes, radula, and operculum, at once separate this genus from any which it approaches in shell-character.[2]
