Caption: Figure 1.
Revised parallel-sequence morphological classification of galaxies. E types are from Kormendy & Bender (1996). Transition objects between spirals and S0s (van den Bergh's anemic galaxies) exist but are not illustrated. Bulge-to-total ratios decrease toward the right; Sc and S0c galaxies have tiny or no pseudobulges. Sph and Im galaxies are bulgeless.
