Ancilla acuminata is a species of sea snail, a marine gastropod mollusk in the family Ancillariidae. ^[2]

Description

(Original description in Latin) The shell is elongated, cinnamon-colored or white, and faintly tawny internally. The spire is exserted and acuminated. The suture is calloused. The body whorl is subangulate. The inferior suture is white, with a simple, chestnut inferior band. The varix is thick, tortuous, and striated. The aperture is oblong and unidentate (one-toothed) below.

An angle in the body whorl imparts a pyramidal form to the spire, which is also characterized by a slight rising around the whorls at the suture. The sides of the shell are rather straight. In other respects, it resembles the more acuminated specimens of Ancilla albisulcata . ^[3]

Distribution

This species occurs in the Red Sea; also off Eritrea, Madagascar, Tanzania, Seychelles, India.
