Popis: The LHCb experiment has recently reported two excited $\Omega_c$ resonances decaying to $\Xi_c^+ K^-$, with masses about 3185 and 3327 MeV. We discuss their assignment to $2S_{1/2}$ and $2S_{3/2}$ states, which can be compared with masses based on extrapolation from the observed 1S states. The agreement is not perfect, but weighs against an earlier alternative assignment.
