Turbinella truncata G. B. Sowerby III, 1892 · Vasum truncatum is a species of large predatory sea snail, a marine gastropod mollusk within the family Turbinellidae.

(Originally described as Turbinella truncata) The solid, white shell has a subcylindical-turbinate shape.

The anterior portion answering to the rostrum in the typical form as in Turbinella pyrum (Linnaeus, 1767) is quite half as broad as the widest part of the shell, and the anterior part of the elongated, white aperture is so little narrower than the posterior, that it can scarcely be called a siphonal canal.

The four small, slightly oblique plaits are situated about (or a little below) the middle of the columella.
