A significant empty region was found between the southern Pavo- Indus (PI)wall and the northern Perseus-Pisces (PP) chain. This survey tests the realityof this void which may simply reflect previous poor sampling of the galaxies inthis region. Redshifts for a magnitude selected sample of 379 galaxies wereobtained covering the four UKST/SERC survey fields with Bt <= 17.0. Allredshifts were obtained with the FLAIR multi-object spectroscopy system on the1.2 m U.K. Schmidt Telescope at Siding Spring, Australia. Two highlysignificant density enhancements were found in the galaxy distribution at 133Mpc and 200 Mpc (Ho=75 km/s/Mpc). We claim that no connexion exists between PPand PI. However, a southern extension of PP was detected and makes the totallength of this chain of more than 150 Mpc.Comment: 14 pages, postscript including tables and figures
