Description Protoconch of U smooth whorls; 4 postnatal whorls. Aperture subequal to, or slightly longer than, spire. Sculpture consisting of rounded axial ribs and spiral lirae. Axial ribs: 11-12 on first whorl; 11-12 on second whorl; 11 on third whorl; 11 on body whorl. Spiral hrae: 4 on first whorl; 5 on second whorl; 5 on third whorl; 5 (with 1 or 2 very fine intermediates) on fourth whorl; 18-20 on body whorl (outer lip), including several finer intermediates; lirae running on to anterior canal. Lirae somewhat broadened at intersection with axial ribs, but never becoming bead-like. Narrow, smooth columella callus present. Inner surface of outer lip with 8-10 faint spiral ribs. Remarks Ocenebra petrocyon most closely resembles O. purpuroides (Reeve, 1845) (with which it was collected), especially in general shape and body-whorl sculpture. The new species differs from O. purpuroides in that the upper two or three whorls are not cancellate; in having more spiral lirae per whorl; in having spiral lirae evenly spaced between the upper and lower suture fines (O. pur-.
