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.^[2]

(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.^[3]

Distribution

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