A new determination for the levels of the nucleus $\chem{^{208}Tl}$ was performed by measuring the $\gamma$-rays following the $\beta ^{-}$-decay of $\chem{^{208}Hg}$. Twenty-six $\gamma$-rays were assigned and three new levels of $\chem{^{208}Tl}$ at 1.728 MeV, 1.652 MeV and 1.362 MeV have been affirmed. A partial $\chem{^{208}Hg}$ decaying $\gamma$ scheme was proposed. The experimental level structure was compared with a shell model calculation.
