${{\mathit \Xi}{(1950)}}$

$I(J^P)$ = $1/2(?^{?})$ 
We list here everything reported between 1875 and 2000 MeV. The accumulated evidence for a ${{\mathit \Xi}}$ near 1950 MeV seems strong enough to include a ${{\mathit \Xi}{(1950)}}$ in the main Baryon Table, but not much can be said about its properties. In fact, there may be more than one ${{\mathit \Xi}}$ near this mass.
