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 position of the pallial sinus is often clearly visible as a shiny line on the inside of the bivalve shell.
