The standard “charmonium” picture predicts four C=+1 states ( 3P 0, 3P 1, 3P 2, 2 1S 0) between ψ and ψ′. If these are identified with the four experimentally observed levels, serious difficulties arise. We remark that a ,,forgotten” 1D 2 level ( JPC=2 ∓) is likely to be around 3.5 GeV. It may be identified with χ(2.45) or χ(3.50), avoiding the above above difficulties. The 2 1S 0 level has then yet to be discovered.
