  We present results from Experiment E917 for antilambda and antiproton
production in Au+Au collisions at 11.7 A GeV. We have measured invariant
spectra and yields for both species in central and peripheral collisions. We
find that the antilambda/antiproton ratio near mid-rapidity increases from
0.26+0.19-0.15 in peripheral collisions to 3.6+4.7-1.8 in central collisions, a
value that is substantially larger than current theoretical estimates.
