${{\boldsymbol \Xi}_{{c}}{(2815)}}$ $I(J^P)$ = $1/2(3/2^{-})$ 

Seen in both ${{\mathit \Xi}_{{c}}^{\,'}}{{\mathit \pi}}$ and ${{\mathit \Xi}_{{c}}}{{\mathit \pi}}{{\mathit \pi}}$ decays. The simplest assignment is that this belongs to the same SU(4) multiplet as the ${{\mathit \Lambda}{(1520)}}$ and the ${{\mathit \Lambda}_{{c}}{(2625)}}$, but the spin and parity have not been measured.
