				<para>
    A new catalogue of 660 galaxies within a field of about 10 square
    degrees in the Perseus cluster region is presented. The catalogue
    contains accurate positions, isophotal magnitudes, angular radii,
    position angles, radial velocities, morphological types, and detailed
    informations on morphological peculiarities. If available, cross
    identifications and radial velocities are also given. The catalogue is
    estimated to be complete to a 25mag isophotal B magnitude of about 18.</para></description>

   The following symbols are used:
     IN: systems with signs of strong interaction in the form of
          bridges (br) and/or tails (ta)
    DIS: systems with signs of distortions, which can show one
          or several of the following features coded by a number:
           (1) peculiar spiral arms
           (2) three-armed spirals
           (3) M51 type
           (4) unusual dust absorption
           (5) elliptical galaxy with isophote twist
           (6) non-concentric core
           (7) loops/shells
           (8) jet-like structures
           (9) fuzzy structure in the outer regions
          (10) radial spikes
  CH(n): n systems (n>1) within a common halo
     PL: polar ring galaxies or related objects
     f*: estimation of morphology hampered by a nearby foreground star
  The strength of the morphological peculiarity is indicated
    (+ for strong, - for weak).
