On fourth and subsequent whorls there is a change in ornamentation, consisting of tubular spines and growth lines between spines. At the beginning of the fourth whorl three spines are present, one in the lower suture, and the other two above this spine, then every 15 degrees another set of three spines appear. each spine is joined by thick lines of growth.
