It is believed that the QSO phenomenon is a form of violent activity in the nuclei of galaxies. This view has found support after the recent detection of nebulosity around a large number of quasars. The nature of the fuzz is not yet clear, but there is some evidence that it is normallly a spiral galaxy hosting a quasar (e.g. Hutchings et al. 1984). However, the experience with radio galaxies suggests that the host of a radio loud quasar ought to be an elliptical galaxy. We have considered the appearance of elliptical galaxies of various redshifts with a view towards determining the nature of ellipticals which could act as hosts for radio quasars at large redshifts. For spirals we have considered the data given by Boroson (1981) and calculated the appearance of different morphological types at large redshifts.
