The shellsize varies between 7 mm and 25 mm. The oblong-ovate shell is spirally peculiarly rudely ridged. The ridges are very irregular and rather scaly, somewhat smooth next the perforations which are slightly tubiferous and distant. The coloration is reddish-orange. The interiorsurface is silvery. This is a very characteristic species, to which there is little or no approximation in any other.
