Alvio Renzini developed a diagnostic for these objects formation. A large one of these in the Virgo
 Cluster is M87. Certain parameters describing these are constrained by the fundamental plane. Type II
 supernova have not been observed to occur in these. The brightness of these objects is characterized by De
 Vaucouleur's Law. The velocity dispersion and luminosity of these are related by the Faber–Jackson
 relation. They are measured on a scale that runs from zero to seven. These objects tend to have little star
 formation because of the lack of interstellar matter, and are composed of old stars with low mass. They can
 be classified according to the ratio of their major and minor axes. For 10 points, name these galaxies which
 are neither lenticular nor spiral.
