Scientific paper

We have obtained R-band surface photometry of 70 dwarf elliptical galaxies in the Virgo Cluster. We find, in contrast to the results of earlier studies, that the dwarfs have a markedly flatter distribution of ellipticities than either 'normal' elliptical galaxies or brightest cluster ellipticals. The ensemble of nucleated dwarfs is rounder than the non-nucleated galaxies. Neither the nucleated nor the nonnucleated dwarfs, however, have distributions as round as giant ellipticals.
