Scientific paper

We have completed a survey of early-type galaxies in a region covering 700 sq. degrees with cz<7000km/s. We find no early-type galaxies with MB > -20 that satisfy our isolation criteria. The sample galaxies obey the Mg-sigma relation but have a higher frequency of [OII] and [OIII] emission than found in the Fornax cluster. They appear to be younger than the ellipticals in the Fornax cluster having a spread in luminosity weighted ages similar to lenticular galaxies. This work was funded by the PPARC rolling grant: ``Extragalactic Astronomy and Cosmology in Durham 2000-2004'' PPA/G/O/1999/00604.
