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