Remarks

Originally described by Conrad (1841) as Delthyris mucronatus.

From Wilson (2014, p. 115): “Medium-sized shell, with hinge line extended, sometime into long ‘mucronate’ projections. Cardinal area narrow. Both valves moderately convex, with well-marked sinus and fold. Surface with distinct striae and growth lines. To 20-50 mm.”
