Vexillum cernohorskyi explained

Vexillum cernohorskyi is an extinct species of sea snail, a marine gastropod mollusk, in the family Costellariidae, the ribbed miters.[1]

Description

The length of the shell attains 8.2 mm, its diameter 2.7 mm.

(Original description) The small, slender shell has a fusiform shape. The protoconch consists of about two smooth, glassy whorls, followed by about seven sculptured whorls. The early whorls ofthe spire are nearly flat, the later whorls slightly more convex. The suture is lightly impressed. The sculpture consists of broad, rounded, slightly curved, axial ribs thatare regularly spaced, 10 or 11 on the body whorl. Weak spiral striae are present in the depressions betweenaxial ribs. The aperture is elongate and shorter than spire;.The columella has four inclined folds. Traces of four dark bands of color are discernible on the Body whorl, the highest one thinner than the other three.[2]

Distribution

Fossils of this marine species were found in late Miocene strata in the Eniwetok Atoll .
