Examples of Dwarf Ellipticals:
- NGC 147 (DDO 3) - type dE5 pec in Cassiopeia
- GR 8 (DDO 155) - type Im V
- SagDIG (Sagittarius Dwarf Irregular Galaxy) - type IB(s)m V in Sagittarius
- Barnards Galaxy (NGC 6822) - type IB(s)m IV-V in Sagittarius
- Aquarius Dwarf (DDO 210) - type Im V in Aquarius
- IC 5152 - type IAB(s)m IV in Indus
- Pegasus Dwarf (DDO 216) - type Irr in Pegasus
A subtype of dwarf ellipticals is called dwarf spheroidal galaxy.
