Material. Anda2 (1) RGM 1008320.

Characterization. Shell large, 117 mm. Protoconch damaged. Spire of moderate height, outline slightly concave. First several postnuclear whorls tuberculate. Sutural ramps slightly concave, with 3 increasing to 11 spiral grooves. Shoulder rounded. Last whorl conical, with a straight to weakly convex outline. Lower one-third of last whorl with weak axially striate grooves and spiral ribbons in between and narrow at base. Columella curved to left at base.

Distribution. Japan, Philippines, New Caledonian area; possibly also S.E. Pacific, in 180–550 m ( Röckel, Korn & Kohn, 1995). Japan, the Philippines and New Caledonia, sandy mud bottom, 200–550 m ( Hori, 2000). Philippines, 150–300 m ( Raybaudi Massillia, 2008).

Remarks. This specimen is large for the species, relatively high-spired and its sculpture is rather coarse, making it a somewhat atypical specimen. However, its characters appear to fall within the range of conchological variation of the species.
