REMARKS. — Protoconch of 2.9 conical whorls, 605 Μm high, 750 Μm wide at the base. Protoconch-I of about 0.9 whorls, sculptured with pustules over the entire surface. Protoconch-II of about 2 whorls, with 2 spiral keels, and sculptured with a series of subsutural threads and a series of similar threads over each keel; a diffuse granulation is present in the interspaces, with granules often fused to give rise to a series of prosocline threadlets between the second abapical keel and the suture.
