We have shown a spectral inclusion between a different spectrum of a C0-quasi-semigroups in [9]. Precisely for Saphar, essentially Saphar, quasi-Fredholm, Kato and essentially Kato spectra. In this paper, we extend these results for a C-quasi-semigroups (regularized quasi-semigroups) where C is a bounded injective operator.
