Ancilla acuminata


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

Description

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 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.

Distribution

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