  We describe a search for compact dwarf galaxies in the Fornax cluster using
the FLAIR spectrograph on the UK Schmidt Telescope. We measured radial
velocities of 453 compact galaxies brighter than Bt=17.3 and found seven new
compact dwarf cluster members that were not classified in previous surveys as
members of the cluster. These are amongst the most compact, high surface
brightness dwarf galaxies known.
  The inclusion of these galaxies in the cluster does not change the total
luminosity function significantly but they are important because of their
extreme nature; one in particular appears to be a high (normal) surface
brightness dwarf spiral. Three of the new dwarfs have strong emission lines and
appear to be blue compact dwarfs (BCDs), doubling the number of confirmed BCDs
in the cluster. We also determined that none of the compact dwarf elliptical
(M32-like) candidates are in the cluster, down to an absolute magnitude
Mb=-13.2. We have investigated the claim of Irwin et al. (1990) that there is
no strong relation between surface brightness and magnitude for the cluster
members and find some support for this for the brighter galaxies (Bt<17.3) but
fainter galaxies still need to be measured.
