DISTRIBUTION. — New Caledonia, Vanuatu, Indonesia, live in 613-616 m, shells in 210-613 m.

DESCRIPTION. — Shell up to 38.5 mm long, solid, glossy. Fresh shells opaque white on dorsal side, translucent on ventral side because of the difference in shell thickness. Slightly curved, sculptured with fine growth lines only. Apex oblique projecting callus present, and long straight slit present on ventral side. In section, dorsal side of shell is thicker than ventral side throughout. Mouth oblique.

Measurements of holotype: L 38.5, W 3.5, w 0.75, arc 2.4.

REMARKS. — This species is characterized by its general shape, section and glossy surface, and by the dorsal-ventral difference in the thickness of the shell, which in fresh specimens gives the ventral side a translucent appearance and the dorsal side an opaque appearance.

ETYMOLOGY. — Named after Gerhard Steiner (University of Vienna, Austria) for his highly valuable contribution to knowledge of the Scaphopoda.
