Description

The white shell has a bulimiform or subglobose shape. 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. It is externally convex. The columella is smooth, arcuate and not dentate.

The animal has long tentacles, and has usually pectinated head lobes. These frontal lobes distinguish this genus from Tricolia, which lacks frontal lobes. The epipodial line contains generally cirrhi. The branchial plume is long. The narrow foot is long, pointed posteriorly, rounded before. Below it is divided longitudinally by a median groove. The rhomboidal jaws are covered with imbricating scales. The radula is rather short. The formula of teeth is typically ∞ 5.1.5 ∞, but sometimes lacks the median and outer lateral teeth.[3] Contrary to most spiral species, the two gills in Phasiannela are close together, so as to appear almost as one.[4]

Distribution

The species in this genus occur in the tropical Indo-West Pacific and off Australia.
