Description
Members of this family have thin, brittle shells that have an elongated oval shape. The valves are white with concentric sculpturing, low umbones, and a gap at both ends. The left valve is slightly larger and more convex than the right valve. The ligament is internal and there are no teeth on the hingeline. The interior of the valve is subnacreous, there are two
adductor muscle scars and the pallial line has a broad
pallial sinus
The pallial sinus is an indentation or inward bending in the pallial line on the interior of a bivalve mollusk shell's valves that corresponds to the position of the siphons in those types of clams which have siphons (i.e. siphonate). The posi ...
. The siphons are long and fused for their full length. The mantle margins are also fused except for a small gap at the anterior end.
