The shells in this widespread genus are generally small to moderate in size (7-45 mm long) and fusiform. The spire is high, the suture impressed, and the aperture ovate, with a poorly developed anal sulcus and an unthickened outer apertural lip. The siphonal canal is short to moderately short and open. The body whorl is generally nonvaricate, with obsolete, subdued, or strongly squamoid sculpture. Color is generally muted, in tones of gray, brown, or pale yellow. In all but the open canal and the generally weak shell sculpture, these are typical ocenebrine forms, a relationship corroborated by the form of the operculum and radular dentition.
