Original Description (from Dillwyn, 1817, p. 164-165):
"Shell heart-shaped, ventricose, with numerous transverse membranaceous reflected ribs, and the posterior depression kidney-shaped; margin crenulated.
[...] This shell may at once be distinguished from V. verrucosa by the posterior depression being reniform, and in a specimen now before me, which is two inches and a quarter long, the transverse ribs are more membranaceous, and are not at all tuberculated at either end; the anterior slope in one valve is glabrous; colour whitish, irregularly stained, and marked with spots, or short angulated streaks of pale brown."
