They are all over obliquely minutely striate. encircled by minutely granulose lirae, with smaller ones intercalated. The three first whorls are but little projecting, the fourth is double the length of the first three, the last whorl is inflated. The penultimate and last whorls contain a median series of reddish-brown quadrangular maculations or have the spiral lirae articulated with brown. Beneath they show a less obvious zone of the same color;. The spiral lines number 7 to 8 on the penultimate whorl, 15 on the body whorl. The outer lip is acute, slightly sulcate, with dots of carmine. The inner lip is arcuate, reflexed, and planate. The aperture is subrotund and pearly. The operculum is calcareous and also pearly.[3]
