					<para>
    We present a catalog of morphological and color data for galaxies with
    21&lt;I_814&lt;25mag in the Hubble Deep Field (Williams et al. 1996, in
    Science with the Hubble Space Telescope II). Galaxies have been
    inspected and (when possible) independently visually classified on the
    MDS and DDO systems. Measurements of central concentration and
    asymmetry are also included in the catalog. The fraction of
    interacting and merging objects is seen to be significantly higher in
    the Hubble Deep Field than it is among nearby galaxies. Barred spirals
    are essentially absent from the deep sample. The fraction of
    early-type galaxies in the Hubble Deep Field is similar to the
    fraction of early-types in the Shapley-Ames Catalog, but the fraction
    of galaxies resembling archetypal grand-design late-type spiral
    galaxies is dramatically lower in the distant HDF sample.</para></abstract>
