Range — Miocene or Pliocene of Okinawa and Recent from Sumatra to the Philippines in 150-300 fathoms.

Shell of moderate size, 35-50 mm., broadly fusiform, resembling Gemmula in the strongly gemmate sculpture, but with a broadly conical spire coupled with a quickly contracted base and long straight unnotched anterior canal. The sinus is a shallow broadly open "V", its apex on the peripheral carina. Protoconch indicated as probably multispiral. Operculum and radula unknown. The basal spirals frequently develop irregular flutings over the last half whorl as in some species of Gemmula and Ptychosyrinx.
