Query: Comment on the X(3915) nonstandard hadron candidate   I review the experimental evidence for the $X(3915)$, the candidate
nonstandard meson associated with $\omega J\psi$ resonance-like peaks in
$B\rightarrow K\omega J\psi$ and $\gamma\gamma\rightarrow\omega J\psi$ near
$M(\omega J\psi)=3920$~MeV, and address the conjecture that it can be
identified as the $\chi_{c2}^\prime$, the radial excitation of the $\chi_{c2}$
charmonium state. Since the partial decay width for $B\rightarrow K X(3915)$ is
at least an order-of-magnitude larger than that for $B\rightarrow K\chi_{c2}$,
its assignment as the $\chi_{c2}^\prime$ is dubious.
