1% to 2 inches in length; spire half the length of the grayish white shell;
6 whorls with numerous, indistinct to moderately well-developed, rounded
ribs and more numerous, small, frequently scaled, spiral cords — all of which
gives the shell a rough, sandpaper feel. Whorls in spire shouldered slightly.
Aperture enamel-white. References in 1937 and earlier to Trophon tejmi-sculptus Carpenter are this species. The true temiiscidptiis is an Ocenebra.
