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

Description

The shell attains a length of 17 mm.

(Original description in French) This small shell is ivory-white, with a yellowish tint. It is oval in shape and pointed at the apex, with its spire whorls fused together. The shell is entirely smooth. At its base, a narrow, depressed double furrow leads obliquely to the angle of the right margin, where it forms a small, rather prominent denticle.

The spire is elongated, while the aperture is quite short and narrow, only slightly flared at the base. The columellar fold is a brighter white, small, and striated. A calcareous deposit can be seen on the columella at the posterior angle of the aperture. The interior of the shell is a very pale tawny color. ^[3]

Distribution

This species occurs in the Red Sea and off Yemen.
