Description

Shell slender, fusiform, small to medium-sized for genus (attaining 30.8 mm, ANSP 456861). Protoconch multispiral of 4.25 whorls ( Fig. 3K ), conical, smooth, except scattered microgranules more dense along suture, flesh coloured with reddish thin line along suture. Whorls somewhat convex, last ½ whorl with 11–12 rounded axial riblets progressing in strength, protoconch/teleoconch boundary without varix, defined by appearance of spiral sculpture. Protoconch diameter 1000 µm, exposed height 1240 µm. Teleoconch whorls convex, suture deep, adpressed. Axial sculpture of very prominent ribs, 7–9 per whorl. Spiral sculpture of evenly spaced strong cords, 2 on first whorl, 3–4 on penultimate whorl, 8–9 on last whorl and shell base, becoming much weaker on canal. Weaker but distinct secondary cords between primary cords, one on earliest whorls increasing to 5 on last whorl, primary and secondary cords becoming similar in size on canal. Siphonal canal long, open, straight, about ¼ of shell length. Aperture with 7–8 smooth teeth periodically appearing and corresponding to interspaces between axial ribs. Inner lip adherent, forming smooth, white columellar callus, 2–3 distinct columellar rounded plicae, adapical two more prominent than abapical one. Teleoconch light brown, usually with lighter spiral band on whorls periphery.

Radula (MNHN IM-2013-58726, SL 14.1, AL 3.1 mm, Fig. 4 B ) 2.13 mm in length (69% of AL), of about 125 transverse rows of teeth, of which 30 nascent. Radula narrow, distance between outer edges of lateral teeth about 50 µm (1.6% of AL without canal). Lateral teeth medium broad, arcuate, with attenuated outer anterior corner, producing long ‘handle’. Lateral teeth with three cusps on right side and four on left side, subequal in length, closely spaced, slightly curved and an additional small but distinct innermost cusp. Inner cusp(s) slightly narrower than lateral ones. Central tooth small, long trapezoid with narrower base, with three cusps, central one nearly twice as long as outer ones.

Distribution

Very widely distributed: in Indo-Pacific, from Taiwan and the Philippines, to French Polynesia, Madagascar and off Réunion. Recorded at depths from 170 to 920 m, alive in 225– 610 m. Unconfirmed depths from commercial sources in the Philippines from 40 m.

Remarks

The species has a smooth columella and therefore is well differentiated from its congeners with columellar plicae. Besides, G. williami comb. nov. has a small, rather slender shell with attenuated straight canal. It is most similar to Granulifusus norfolkensis sp. nov., differing in details of colouration and in having a straight siphonal canal rather than inclined to left. Molecular data clearly separate the two species.
