Shell small, slender, whitish, with a brown reticulate acute nucleus of three, and eight subsequent whorls; suture deeply constricted but not solute; whorls inflated; spiral sculpture of (on the last whorl five or six) rounded cords, equally distributed with somewhat wider interspaces, overrunning the ribs and slightly swollen at the intersections; there is a well-marked basal disk the edge of which is covered by the suture, and which carries five or six fine close spiral threads; axial sculpture of (on the last whorl 15) strong rounded ribs, the final rib or varix larger than the others; base imperforate, aperture rounded. Length, 6.5; diameter, 2 mm. U. S. Nat. Mus. Cat. No. 333464. Off Georgia, four specimens.

Rare, known only from deep water at depths of over 400 fathoms, off the coast of south Florida. A solid shell, reaching about 10mm, with 13 whorls and an angle to spire of about 32 degrees. A dull yellowish gray color. Axial sculpture consists of 14 strong costae on the body whorl, not continuous from the whorl above. There are also thread-like axial lines on the surface of the shell as well as 7 to 8 strong spiral ridges making nodes as they cross the costae. There is a strong basal ridge. On the base of the shell, the axial costae are absent and the spiral lines are weak. It can be distinguished from C. andrewsii by the ribbed nuclear whorls and the fine spiral lines on the surface of the shell.
