Phasianella, common name the pheasant shells, is a genus of small sea snails with a calcareous operculum and a colorfully patterned shell, a marine gastropod mollusc in the family Phasianellidae.
It is polished, without epidermis or nacre, variegated with bright colors.
The heavy operculum is calcareous, internally paucispiral, with a nucleus near the basal margin.
[4] Contrary to most spiral species, the two gills in Phasiannela are close together, so as to appear almost as one.
[5] The species in this genus occur in the tropical Indo-West Pacific and off Australia.
