Description

The shell size 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 interior surface is silvery. This is a very characteristic species, to which there is little or no approximation in any other.H.A. Pilsbry (1890) Manual of Conchology XII; Academy of Natural Sciences, Philadelphia, 1890
