CRETACEOUS FOSSILSconch broken away. Whorls about four, increasing in size with considerablerapidity. A shoulder is formed by a broadly excavated bandbelow the suture. A narrow collar borders the suture but no nodes canbe observed on it. Conspicuous axial ribs, impossible to count because<strong>of</strong> the imperfect state <strong>of</strong> the fossil. The iurials are most conspicuousnear the shoulder and fade out gradually near the base. The entire surfaceis covered with faint striae. Aperture not observed. Length 19.0mm. ; greatest width 13.0 mm."

Shell fusiform with about three or four volntions,suture well defined, outer volution produced below into a rather shortanterior canal. Surface <strong>of</strong> the volntions <strong>of</strong> the spire convex from sutureto suture, and marked by a series <strong>of</strong> elongate, slightly oblique, rathersharp nodes, about 11 or 12 on each volution, which originate close tothe upper suture, become strongest at about the mid-height <strong>of</strong> the volutionand grow fainter below to the lower suture. Upon the outer volutionthe nodes resemble those <strong>of</strong> the spire and become obsolete below,about half way between the suture and the extremity <strong>of</strong> the anteriorcanal; the surface <strong>of</strong> the outer volution is convex from the suture tobelow the middle where it becomes concave as it passes into the anteriorcanal, the periphery being without a distinct angulation. Surface <strong>of</strong> theshell marked throughout with fine revolving lines.
