This species was named after the pet cat of Jerry Walls. Usually solid to moderately heavy. Last whorl narrowly conical to conical, occasionally ventricosely conical; outline slightly convex at adapical fourth or sometimes two-thirds, straight below, often with a slightly concave central area. Shoulder angulate to broadly carinate. Spire low, outline concave; early whorls usually projecting from an otherwise rather flat spire. Teleoconch sutural ramps tlat to slightly concave, with 2 increasing to 4-7 spiral grooves, often weaker in latest whorls. Shells with variably spaced and strongly granulose spiral ribs from base to subshoulder area intergrade with shells with variably prominent, smooth or granulose ribs at base.
