Here, with a data sample of $980{\mathrm{fb}}^{-1}$ of $e^{+}{e}^{-}$ annihilation data taken with the Belle detector operating at the KEKB asymmetric-energy $e^{+}{e}^{-}$ collider, we discuss the results of a study of excited ${\mathrm{\Xi }}_c$ states that decay, via the emission of photons and/or charged pions, into ${\mathrm{\Xi }}_c^0$ or ${\mathrm{\Xi }}_c^{+}$ ground state charmed-strange baryons. We present new measurements of the masses of all members of the ${\mathrm{\Xi }}_c^{\text{'}}$, ${\mathrm{\Xi }}_c\left(2645\right)$, ${\mathrm{\Xi }}_c\left(2790\right)$, ${\mathrm{\Xi }}_c\left(2815\right)$, and ${\mathrm{\Xi }}_c\left(2980\right)$ isodoublets, measurements of the intrinsic widths of those that decay strongly, and evidence of previously unknown transitions.
