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.
This is the only species of Phasianotrochus outside Australia.
