Ward ; Brodie, Jean P. ; Batuski, David J. Abstract Evidence is presented for the existence of a large region of space in Pisces-Cetus that is empty of galaxies and clusters of galaxies. The data base consists of rich clusters from the Abell catalog, galaxies from the CfA survey, and new galaxy redshift data collected at Lick Observatory. The volume of this roughly spherical, 40h^-1^ Mpc diameter void is comparable to the largest empty region (free of emission-line galaxies) in the recently completed study of the Bootes void. We argue that the observed distributions of galaxies and clusters within the Pisces-Cetus void region are unlike that expected for a uniform distribution taking into consideration observational sampling. We also compare the properties of the Pisces-Cetus void with the results of recent numerical simulations of large-scale structures within hot and cold dark matter scenarios and explosion models.
