The selfdiffusion coefficient (0) of a hard sphere of variable sire and mass, moving in a solvent of hard spheres of fved size and mass, is calculated in a version of the ring approximation (RA). It is found that (a) the ring contribution to D vanishes for particles smaller or less massive than the
