Four new superdeformed bands have been observed with the Gammasphere array and have been assigned to the ${}^{195}$Hg nucleus. Two of the bands are interpreted as signature partners most likely based on $N_{\mathrm{osc}}$=6 neutron quasiparticles coupled to a superdeformed core, while the other two appear to be based on a $j_{15/2}$ intruder orbital. These four bands do not exhibit a simple, “identical bands” relationship to other superdeformed bands in this mass region.
