Vexillum turben explained

Vexillum turben, common name the spinning-top mitre, is a species of small sea snail, marine gastropod mollusk in the family Costellariidae, the ribbed miters.

Description

The length of the shell attains 22.7 mm, its diameter 12 mm.

(Original description) The shell is oblong-ovate, attenuated at the base. The spire is obtusely rounded. The sutures are rather deep. The shell is longitudinally very closely plicately fine-ribbed. The ribs and interstices are transversely impressely striated. The shell is orange-yellow. The columella is five-plaited with the plaits prominent. The aperture is striated within. ^[1]

(Described as Vexillum turben kanak) The shell is similar to Vexillum turben (Reeve, 1844) (Philippine Islands) in sculpture and the ochraceous-buff or buff-yellow color, but the spire is more shortly and a little concavely conic above, the penultimate whorl is slightly swollen. There are six plaits, the upper one strong and horizontal. Within the outer lip there is a small fold, more prominent than the others about the upper third. ^[2]

Distribution

This marine species occurs in the Indo-west and central Pacific, off Mozambique, the Philippines and Hawaii.
