Mioawateria extensaeformis

(Original description) The rather strong, ivory-white, ovate shell has a short spire.

The subsequent whorls are scarcely excavated, the place of the excavation being occupied for a great deal by a rather strong, subsutural spiral, adorned by strong, laterally compressed beads, 22 in number on the body whorl.

The space between the ribs is sculptured by fine and coarse growth-lines and faint spiral striae, becoming stronger and groove-like towards the base of the body whorl, and have the character of lirae on the short, large siphonal canal.

The aperture is oval, with a moderately sharp angle above and a wide, slightly gutter-like canal below.

[2] This marine species was found off Western Sumatra and in the Banda Sea, at depths between 462 and 750 m
