s. The 3½ subsequent whorls show a distinct suture. The spiral sculpture shows between the sutures two prominent keels and an anterior smaller one on which the suture is laid. On the

there are about eight minor threads in front of those mentioned, all with wider interspaces. The axial sculpture consists of prominent oblique lines protractively cutting the interspaces. The anal sulcus is shallow, distinct and close to the suture. The outer lip is thi and slightly produced. The inner lip is erased. The columella is short and straight. The
