Production of Lambda and Antilambda hyperons was measured in central Pb-Pb collisions at 40, 80, and 158 A$\cdot$GeV beam energy on a fixed target. Transverse mass spectra and rapidity distributions are given for all three energies. The $\Lambda-\pi$ ratio at mid-rapidity and in full phase space shows a pronounced maximum between the highest AGS an
