  We report 2868 new multi-object spectroscopic measurements of galaxy
redshifts in an area roughly 12\deg$\times$ 6\deg (right ascension $\times$
declination) centered on the Shapley Supercluster (SSC). These correspond to
2627 different galaxies. Including other measurements reported in the
literature, the total number of galaxies with measured redshifts in a
19\deg$\times$ 16\deg area centered on the supercluster now reaches 5090. Of
these, 2949 lie in the redshift range 9,000 - 18,000 km s$^{-1}$, which we
tentatively identify with the SSC. This unprecedented sample allows a quite
detailed qualitative morphological study of the SSC. Based on the
three-dimensional distribution of galaxies and clusters of galaxies, we
identify several sub-condensations of the supercluster, as well as walls and
filaments connecting them. We also find another supercluster in the background,
at redshift $\sim$ 23,000 km s$^{-1}$.
