Vexillum unifasciale is a species of sea snail, a marine gastropod mollusk, in the family Costellariidae, the ribbed miters.[1]
Description
The length of the shell attains 19 mm, its diameter 8 mm; the length can attain 29 mm.
(Described as Mitra fratercula) The oblong shell is subfusiform, solid, shining and, contracted at the base. The spire is moderately elevated, acute, brownish-yellow, transversely lineated with deep brown, and adorned with a spiral white band. The shell contains 8-9 whorls, plano-convex, slightly shouldered, longitudinally ribbed. The ribs are small, closely set, angular, 16 to 18 in number, slightly nodulose above, and the interstices remotely transversely impressedly striated. The body whorl is large, roundly convex, granulated towards the base. The aperture is narrow, little less than half the length of the shell, bluish white and lyrate within. The columella has four folds.
The animal is light brown, dotted and mottled with yellowish white.
This is a very rare species, found under stones on reefs.[2]
