Abstract
I review the experimental evidence for the , the candidate nonstandard meson associated with resonance-like peaks in and near ~MeV, and address the conjecture that it can be identified as the , the radial excitation of the charmonium state. Since the partial decay width for is at least an order-of-magnitude larger than that for , its assignment as the is dubious.
