Vexillum polygonum is a species of small sea snail, marine gastropod mollusk in the family Costellariidae, the ribbed miters. ^[1]

Description

The length of the shell attains 34 mm. Adult shells are slender and fusiform, ranging from about 20 to 40 mm in length. Each whorl bears 14–18 broad axial ribs crossed by fine spiral threads that create a low-noded, “quilted” sculpture. Background colour varies from ivory-cream to pinkish, over-lain by irregular chestnut-brown blotches that form polygonal patches—hence the specific epithet polygonum. The aperture is narrow; the columella displays four distinct plaits, the anterior two being strongest, and the inner lip is smooth. ^[2]

Distribution

This marine species occurs in the Indo-West Pacific (Madagascar, the Philippines, Solomon islands, New Caledonia); also off Australia (Queensland).
