  In this paper we present the results of a spectroscopic survey of galaxies in
an area between the two clusters of galaxies A548 and A3367, suspected to be a
close and interacting pair. With the use of multifiber spectroscopy, we
measured 180 new velocities of galaxies in the central part of A3367 and in the
external regions of A548.
  The redshift histogram shows the presence of three velocity peaks, at v ~
12000 km/s, v ~ 30000 km/s and v ~ 40000 km/s, respectively. For these we
estimate the density excess, the mean velocity, and the velocity dispersion.
  The first clump corresponds to an elongation of A548: in particular we found
a correspondence between the features of this peak and the substructures of
A548. The second peak has a velocity dispersion which is typical of clusters
and the distribution of its members on the plane of the sky corresponds to the
highest density peak in A3367. We therefore suggest that the name A3367 has to
be attributed to this clump.
  Our general conclusion is that, differently from expected, A548 and A3367 do
not form a close pair of merging clusters, since the two structures are at
significantly different redshifts. Moreover, we found that the complex
dynamical structure of A548 has large coherence, with a projected extension in
the range of 1-3 Mpc.
