The shells in this genus are somewhat globular, rarely with former varices in the spire, usually with numerous spiral threads or incised lines on the outside, usually with rows of squarish, yellowish spots, with a wrinkled columellar shield, and a finely denticulated, thickened outer lip. The base of the outer lip lacks terminal spines, and the longitudinally threaded siphonal fasciole lacks the single, raised ridge found in Echinophoria. The opercullum is fan-shaped and may be smoothish or strongly sculptured radially.
