Abstract
Using data recorded by the CLEO-II detector at CESR, we report evidence of a pair of excited charmed baryons, one decaying into and the other into . The doubly charged state has a measured mass difference of and a width of , and the neutral state has a measured mass difference of and a width of . We interpret these data as evidence of the and , the spin excitations of the baryons.
