Preliminary inclusive spectra for K+, K-, K-3(0), Lambda, and <(<Lamda
>)over bar> are presented which were measured in central Pb + Pb colli
sions at 158 GeV per nucleon by the NA49 experiment. A comparison with
data from lighter collision systems shows a strong change of the shap
e of the Lambda rapidity distribution. The strangeness enhancement obs
erved in S + S compared to p + p and p + A is not further increased in
Pb + Pb.
