At about 6 mm (about 0.24 inch), Parvilucina crenella (Dall, 1901) is one of the smallest local members of the family Lucinidae. Its shell is small, with a delicate sculpture of sculpture of narrow ribs superimposed by commarginal (“concentric”) threads of about the same width as the ribs. The internal margin of valves is crenulated (“wavy”). Shell color is white. This species was in the past known as “Lucina multilineata”. Not commonly found, possibly because of its small size.
