  We find possible candidates for the new type of q bar q meson, mesonic
chiralons, whose existence is predicted in the covariant level-classification
scheme of hadrons with U(12)_SF * O(3,1)_L symmetry, by assigning all the known
light-unflavored and strange mesons, with masses below about 1.8 GeV, to
U(12)_SF * O(3,1)_L multiplets.
