Equivalve.
Equilateral:
Slightly inequilateral, beaks just in front of midline, approximately 40-45% of total length from anterior end. Becomes more inequilateral with growth.

Umbo relatively prominent, relatively narrow, rounded, projecting well above the dorsal margin, anterior of midline.
Sculpture:
Prominent, but irregularly spaced, raised concentric lines.
Margin:
Smooth.
Ligament:
External ligament opisthodetic, visible either side of the beak but very short anteriorly. Tiny internal amphidetic ligament seated below the beak in a minute triangular formed resilifer.
