  We revisit Ricci dark energy in Chern-Simons modified gravity. As far as the
cosmological evolution, this is nothing but the Ricci dark energy with a
minimally coupled scalar without potential which means that the role of
Chern-Simons term is suppressed. Using the equation of state parameter, this
model is similar to the modified Chaplygin gas model only when two are around
the de Sitter universe deriving by the cosmological constant in the future.
However, two past evolutions are different.
