Phasianotrochus hirasei is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails. [1]
Description
The height of the shell attains 15 mm. The ovate-pyramidal shell is solid. The color of the shell is a uniform olive or a brownish-olive, belted with numerous reddish spiral bands. The shell is smooth except for faint growth lines above. The base of the shell scores by 5 or 6 narrow, spaced, concentric grooves that become stronger near the axis. The conic spire contains 6½ convex whorls. The body whorl is subangular at the periphery and convex beneath. The oblique aperture is brilliantly green inside, with a dusky submarginal band and a pale edge. The white columella is opaque and rounded. The umbilical region is imperforate or has a very minute perforation. [1]
This is the only species of Phasianotrochus outside Australia.
Distribution
This marine species occurs off Japan and Korea.
