This species may be recognized by the dark-brown bands on each whorl; the gem-like nodules common to many species are arranged in two prominent rows, with a narrow intervening crenulated ridge; on the last whorl they are smaller and closer, forming six ridges.

high. Shell conical with flat whorls. Teleoconch of 12 whorls with three spiral cords with tubercles at the intersection with slightly prosocline axial ribs. The second cord starts in the lower part of the shell as a fine thread and never fully develops to the size of the others. Fine axial threads are visible in the interspaces. Peristome incomplete in the
syntype
, with faint additional spiral cords. Siphonal canal short. The base bears two additional smooth spiral cords. Protoconch incomplete, but clearly multispiral; the three visible whorls have numerous axial ribs and a single spiral keel. Teleoconch whorls dark brown apically and light brown to whitish abapically. Base very light brown to white, siphonal canal brown. Protoconch hyaline, but worn in the
