To size: To 6-7mm. Shell Structure: Relatively thin and brittle. Equivalve: Equivalve. Equilateral: Inequilateral, the beaks lie approximately 60% of dorsal margin length from posterior. Tumidity: Moderately tumid. Outline: Elongate-trigonal with a relatively long, slightly upturned, pointed rostrum (more roundly truncated in juveniles), and conspicuous radial ridge and furrow on anterior slope: antero-dorsal margin slightly rounded and sloping, anterior end deeply rounded; ventral margin well rounded; escutcheon short and indistinct; lunule long, lanceolate, conspicuously raised with well defined, raised, sharp edges. Contour: Rostrate.
Sculpture: Prominent, well defined, raised but thin concentric ridges, regularly and widely spaced but becoming more closely and less regularly spaced towards the outer margins. Margin: Smooth. Ligament: Internal, opisthodetic, with a rounded triangular ligament seated in a well-developed resilifer. Hinge: Taxodont: relatively solid, continuous hinge plate, anterior part curved (slightly convex), narrow below the beaks, broadening towards the anterior end.
