« Shell conic, pointed, strong, thick, pure white and somewhat glossy. Spires six or seven, with a few distant longitudinal wrinkles which give an undulated appearance to the separating line ; the first volution extending over two-thirds of the shell. Aperture narrow, contracted at the upper part ; the outer-lip thick ; pillar much thickened, reflected and forming a slight perforation, and furnished with two tooth-like folds. » – W. Turton: A conchological dictionary of the British Islands vol. II, London 1819.
