The teleoconch contains five whorls, marked with fine, close spiral striae, becoming coarser on the base. The suture is deep and oblique. The outer lip is flexuous, retreating, sinuated above. It is smooth within. The columellar tooth shows only a slight obscure fold. There is no umbilicus or a very small umbilical chink. [4]
