We present a study of excited charm-strange baryon states produced in$e^+e^-$ annihilations at or near a center-of-mass energy of$10.58\mathrm{Ge\kern -0.1em V}$, in a data sample with an integratedluminosity of $384 fb^{-1}$ recorded with the BABAR detector at the PEP-II$e^+e^-$ storage rings at the Stanford Linear Accelerator Center. We studystrong decays of charm-strange baryons to $\Lambda_c^+K^0_{\scriptscriptstyleS}$, $\Lambda_c^+K^-$, $\Lambda_c^+K^-\pi^+$,$\Lambda_c^+K^0_{\scriptscriptstyle S}\pi^-$,$\Lambda_c^+K^0_{\scriptscriptstyle S}\pi^-\pi^+$, and$\Lambda_c^+K^-\pi^+\pi^-$. This study confirms the existence of the states$\Xi_c(2980)^+$, $\Xi_c(3077)^+$, and $\Xi_c(3077)^0$, with a more accuratedetermination of the $\Xi_c(2980)^+$ mass and width. We also present evidencefor two new states, $\Xi_c(3055)^+$ and $\Xi_c(3123)^+$, decaying through theintermediate resonant modes $\Sigma_c(2455)^{++}K^-$ and$\Sigma_c(2520)^{++}K^-$, respectively. For each of these baryons, we measurethe yield in each final state, determine the statistical significance, andcalculate the product of the production cross-section and branching fractions.We also measure the masses and widths of these excited charm-strange baryons.
