${{\mathit \Xi}_{{{c}}}{(2815)}}$

$I(J^P)$ = $1/2(3/2^{-})$ 
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.
