Phenacoptygma Dall, 1918 is removed from the Volutidae and placed in the synonymy of Surculina Dall, 1908, which in turn is removed from the Turridae and assigned to the Turbinellidae near Benthovoluta Kuroda and Habe, 1950, on the basis of its radula. It is pro posed that the families Turbinellidae (olim Xancidae) and Vasidae be of coordinate rank. A new species of Benthovoluta, B. gracilior, is described from the Sulu Sea, Philippines.
