can be readily told apart from its congeners by two strongly marked spiral cords on the median portion of the whorl bearing prominent spikes resembling rose thorns; subsutural and suprasutural spiral cords similar to the two stronger ones in structure, but much weaker, with less prominent spikes - probably, an adult specimen would have more of such cords, as an increase in the number of cords as the shell grows is seen in nearly all congeners.
