Abstract
Description.—Specimen from the Coralline Oolite of Pickering (Leckenby Collection).Shell moderately elongate, conical, solid. Spire formed of an angle very nearly regular. The whorls are numerous and of moderate height. The posterior whorls in this specimen have suffered from abrasion. They are nearly flat, and the ornaments were apparently similar to those in the central part of the shell. The ornaments on the anterior whorls, if ever they existed, are for the most part obliterated, but the nodular character of the rim at the base of each whorl is still shown; these whorls are moderately excavated. The ornaments on the portions preserved in the centre are as follows. Each whorl is slightly depressed in the middle, and closely fitted on to the next by a raised nodular rim: that rim which is at the base of each whorl is by far the most nodular. Five transverse rows of granulations, the three centre ones being the strongest, fill up the space between the rims.
