ABSTRACT
We present a catalog of morphological and color data for galaxies
with
21 < I_814 < 25 mag in the Hubble Deep Field (Williams et al. 1996).
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.
