We study the decays ${\mathrm{\ensuremath{\Lambda}}}_{c}^{+}\ensuremath{\rightarrow}\mathrm{\ensuremath{\Lambda}}\ensuremath{\eta}{\ensuremath{\pi}}^{+}$ and $\mathrm{\ensuremath{\Sigma}}(1385{)}^{+}\ensuremath{\eta}$ based on ${\mathrm{\ensuremath{\Lambda}}}_{c}^{+}{\overline{\mathrm{\ensuremath{\Lambda}}}}_{c}^{\ensuremath{-}}$ pairs produced in ${e}^{+}{e}^{\ensuremath{-}}$ collisions at a center-of-mass energy of $\sqrt{s}=4.6\text{ }\text{ }\mathrm{GeV}$, corresponding to an integrated luminosity of $567\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$. The data sample was accumulated with the BESIII detector at …
