Cranopsis cearensis: Diagnosis. Apex slightly high, located preceding posterior third. Height ca. 40% of length; width ca. 80% of < length. Sculptured by ca. 60 rounded radial ribs, relatively narrow, profile rounded, extending beyond shell edges; 1 bearing transverse low scales extending on relatively wide interspaces between ribs forming comarginal sculpture. Foramen slightly deviated to right, flanked by low edges; located more posteriorly, separated from anterior edge. ,
Description. Shell size up to 15 mm; low; height ca. 40% length. Pure white. Protoconch of one convex whorl; situated on right; smooth, glossy; 270 µm. Foramen cuneiform (pointed anteriorly), width 16% of length; located at about 25% of shell length posterior to anterior edge; width 4% of shell width, length 38% of shell length; edges irregular. Groove anterior to foramen narrow, flanked by pair of ribs as wide as radial ribs ; shifted to right by ca. 10° relative to longitudinal axis of shell. Beak curved ventrally, between middle and dorsal thirds of shell height; located between middle and posterior thirds of shell length (in dorsal view) ; teleoconch of one whorl; profile highly curved ventrally, as arc with center located in middle level of ventral surface, just on aperture level) . Sculpture regular, of ca. 60 narrow, rounded, radial ribs ; about twice as tall as wide; lower secondary ribs between primary ribs, gradually increasing in width towards margin; interspaces between ribs as wide as ribs; transverse, semilunar, low scales arranged along ribs at regular intervals of 1/2-1/3 of ribs width; scales forming series of rectangular pits (ca. twice as wide as long); interspaces between successive scales with series of 10-12 striae in each pit, parallel to scales (Figs 54, 55); ca. 40 scales along ribs close to median line. Selenizone as wide as foramen; edges slightly higher than radial ribs, with sharp edges; lunules regular distributed, well-spaced (Figs 48-52). Aperture planar , outline elliptical, width ca. 80% of length; edges undulating due to radial sculpture. Inner surface smooth, glossy. Septum well-developed, 16% of shell height; 3 times longer than wide; ventral edge slightly concave, 19% of aperture width; forming concavity protecting posterior edge of foramen. Measurements (in mm). Holotype: 13.0 by 5.2;
