Physical Description

Morphology

Shell variable, more or less elongate-modioliform, beaks subterminal but close to the anterior margin. Ventral margin straight to more or less concave. Postero-dorsal margin slightly to markedly convex, occasionally straight. Ligament plate slightly arched. Exterior with dense irregular growth lines and growth waves. Periostracum dull, warm chestnut brown, in umbonal region and often also postero-dorsally lighter brown. Anterior byssus retractor scar in the umbonal cavity, under the beaks. Anterior part of posterior byssus retractor muscle scar under ligament?s end or slightly forward. Animal with large gills. Mantle lobes on anterior half of ventral side separate. Valvular siphonal membrane short, narrow and rather strong.
