The length of the shell varies between 40 mm and 90 mm. (Original description in Latin) The white shell is fusiform and robust. It is faintly reddish-banded below the suture and reddish-dotted between the tubercles around the middle of the whorls. There are 10-12 convex whorls, encircled below the suture by a double band and around the middle by another flattened, tuberculated band. They are adorned with a few thin spiral lirae and conspicuous growth lines. The body whorl, below the band, is encircled by 5-6 lirae and intercalating striae, narrowing inferiorly and produced into a rostrum (beak). The columella is slightly oblique and rather straight. The outer lip is thin and incised at the tuberculated band. The aperture is lirate internally. ==Distribution==
