In order to investigate in 3D the galaxian density enhancement located in the south of the Pisces Perseus Supercluster, a redshift survey is conducted of early-type galaxies with a diameter greater than 1 arcmin in a region bounded by 20 h and 6 h, and -20 and 0 deg. Data presented include those for 157 radial velocities which, added to all the previously known redshifts in this region, show a galaxy distribution concentrated around 5000 km/s and the presence of a void of about 25/h Mpc. These two characteristics are the same as the ones found by Haynes and Giovanelli (1989), in the northern part of the Pisces Perseus Supercluster, suggesting that it could extend toward the south. A comparison with the recent data obtained in the same region by Pellegrini et al. (1990) is presented.
