The size of the shell varies between 13 mm and 63 mm. The shell is yellowish brown, pink-brown or olivaceous. It is sometimes chocolate-brown, very closely nebulously spotted and reticulated. And sometimes it is interrupted-lined with chestnut, with a narrow, light band below the middle. The spire is elevated, rudely gradate and maculated. The interior of the aperture is light chocolate, with a light band.
The peptide Contryphan-Vn was extracted from the venom of this marine snail. It is part of a complex mixture of poisonous compounds secreted by this cone snailand used in worm hunting.
