Description
The behavior of the isophotes of the E galaxies in a new photometric
sample of 33 early-type galaxies belonging to the Virgo cluster (Caon)
is compared to that of the S0 galaxies. Almost all objects flatter than
b/a = 0.2 are found to exhibit 'pointed' (or 'lemon-shaped') isophotes
irrespective of their Hubble class, while almost none do if rounder than
the same limit. This observation is used to support the incipient
scenario in which a large fraction (about 1/2) of E galaxies - the
so-called 'disky ellipticals' - populates one end of a disk-to-bulge
sequence including S0 and spiral galaxies.
