A search for SU(3) manifestly exotic e2Q baryonium states in antiproton-deuterium interactions was carried out at the SLAC 40-in. hybrid bubble-chamber facility. The I = t, S= 1 channel, X -, produced in conjunction with a forward produced neutral antikaon was studied. Such X -states would decay into an antihyperon and a baryon. The fast forward K 0 was detected in a three-view segmented calorimeter placed downstream of the bubble chamber and used as part of the trigger. Upper limits of 0.50-1.63 pb are reported for the X--Kn.rr-, 3 -n , xPv-r-, -p i --, E ' n r F . r r -exclusive channels based upon 2 13 events per channel.
