| Summary:
The LHCb experiment has recently reported two excited $Ω_c$ resonances decaying to $Ξ_c^+ K^-$, 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.
