Seen in ${{\mathit \Xi}_{{c}}^{\,'}}{{\mathit \pi}}$ decays. The simplest assignment, based on the mass, width, and decay mode, is that this belongs in the same SU(4) multiplet as the ${{\mathit \Lambda}{(1405)}}$ and the ${{\mathit \Lambda}_{{c}}{(2595)}^{+}}$ , but the spin and parity have not been measured.
