Rediscription from Clench & Aguayo, 1952:434-435

Description. Shell reaching 30 mm. (about 1¼ inches) in length, rather solid, rimately perforate and strongly sculp­tured. Color a rather dark gray, the axial costae being some­what lighter. Whorls 11, moderately convex. Spire extended, cylindric to about the fourth whorl above the aperture, then convexly conic to the apex and produced at an angle of about 55°. Aperture subquadrate. Outer lip reflected, somewhat ex­panded and rather thin. Parietal ridge strong and nearly straight making the aperture holostomatous. Parietal tooth centered and extending back for a very short distance. Colu­mellar tooth small, relatively inconspicuous and extending back for nearly a full whorl. Columella short and nearly straight. Umbilicus rimately formed and shallow. Suture moderately impressed. Sculpture consisting of numerous, ir­regular axial costae numbering 14 to 18 on the body whorl. Spiral sculpture consisting of numerous incised lines which cut into the shell, even over the axial costae. Nuclear whorls very finely costate. Powdered element light and seen best along the edges of the incised lines. Agglutinated sand grains present though mainly restricted to the umbilical area.

Remarks: Clench & Aguayo (1952:434-435) considered Cerion felis to be "probably a hybrid element that has retained most of the general characters of the scalarinum complex and yet shows certain characters of C. glans, many colonies of which exist on Cat Island."
