Are the Perseus-pisces Chain and the Pavo-indus Wall Connected?

In this paper we present a new redshift survey undertaken to address the rather interesting question that arises when all the currently available redshift information from the LEDA database is plotted in`hypergalactic' coordinates. A signiicant empty region was found between the southern Pavo-Indus (PI) wall and the northern Perseus-Pisces (PP) chain. This survey tests the reality of this void which may simply reeect previous poor sampling of the galaxies in this region. Redshifts for a magnitude selected sample of 379 galaxies were obtained covering the four UKST/SERC survey elds: #537, #470, #346, #290 with 15:5 B T 17:0. All redshifts were obtained with the FLAIR multi-object spectroscopy system on the 1.2 m U.K. Schmidt Telescope at Siding Spring, Australia. Two highly signiicant density enhancements were found in the galaxy distribution at 133Mpc and 200Mpc (H 0 =75 km.s 1 .Mpc 1). We claim that no connexion exists between PP and PI. However, a southern extension of PP was detected and makes the total length of this chain of more than 150 Mpc.
