Lirularia yamadana is a species of small sea snail, a marine gastropod mollusk in the family Trochidae, the top snails. [2]
The height of the shell attains 6 mm, its diameter 4½ mm. The ovate-conical, slightly perforate shell is dull whitish. It is painted on the lirae with lilac-brown tessellations, somewhat formed into flammules. The five whorls are convex, and separated by profound sutures, ridged by delicate spiral lirae articulated with lilac-brown (5 to 6 on penultimate, about 20 on the body whorl). The shell shows oblique incremental lines. The pearly aperture is circular, equalling ½ the total length. The columella is a trifle thickened. The terminations of the peristome are joined by a thin callus.
The elongate brownish-lilac spots on the lirations are situated somewhat irregularly underneath each other, so as to form flammulations. [3]
