Characteristics

The elongate shell of Beddomeia phasianella is comparatively smaller than other species of Beddomeia. It has a length of 1.87-2.25mm and a width of 1.15-1.33mm. The Teleoconch (adult shell) has around 2.6-3.4 convex whorls, the shell is consistently rounded at the edge of the last whorl and has faint growth lines towards the helicocone. The periostracum (the outermost layer) of the shell is yellow in color. On the other hand, the protoconch (larva stage shell) has roughly 1.75 whorls, it is covered with faint spiral and axial wrinkles, and exhibit medial indication of pustules. [2]
