The broader of the two states is measured to have a mass of $2978.5\\pm 2.1\\pm 2.0$ MeV/$c^2$ and a width of $43.5\\pm 7.5\\pm 7.0$ MeV/$c^2$. The mass and width of the narrow state are measured to be $3076.7\\pm 0.9\\pm 0.5$ MeV/$c^2$ and $6.2\\pm 1.2\\pm 0.8$ MeV/$c^2$, respectively. We also perform a search for the isospin partner states that decay into $\\Lambda_c^+ K_S^0\\pi^-$ and observe a significant signal at the mass of $3082.8\\pm 1.8\\pm 1.5$ MeV/$c^2$.
