DISTRIBUTION. — Vanuatu, dead collected in 1360 m and Solomon Islands, living specimens in 1136-1138 m, empty shells in 854-1327 m. The present records extend

its geographical distribution further north but also provide information about the bathymetrical range of living specimens.

REMARKS

The largest specimen examined was dead collected and is 46.1 mm high. The operculum and the radula were also examined.

The operculum is light brown, strongly ovate with an extreme apical nucleus. The radula ( Fig. 5B View FIG ) is trophonine with a short, broad central cusp and a short lateral denticle with a weakly longer and broader lateral cusp on each side. It is quite similar to the radula of S. maltzani ( Fig. 5C View FIG ) and S. undocostata (Golikov & Sirenko, 1992) from the Kurile Islands ( Fig. 5D View FIG ).
