Vexillum bouryi is an extinct species of sea snail, a marine gastropod mollusk, in the family Costellariidae, the ribbed miters. [1]
The shell of Vexillum bouryi reaches a length of 18 mm and a diameter of 7 mm. It has an elongate, fusiform shape with a moderately high spire made up of several convex whorls. The surface features distinct axial ribs crossed by fine spiral striations. This creates a ribbed look that is typical of the Vexillum genus.
The aperture is narrow and elongated, ending in a short siphonal canal. The outer lip is thickened and slightly wavy, while the columella has several slanted folds. Fossil specimens do not show their original color, but living relatives of this genus usually have patterned shells.
Fossils of this marine species were found in Eocene strata in Ile-de-France, France.
