Two excited superdeformed bands in {sup 149}Gd have been observed in {gamma}-ray spectroscopy. Based on the behavior of the dynamical moments of inertia, we assign one band to a neutron excitation and the other to a proton excitation. The proton-excited-band {gamma}-ray energies are nearly identical to those already known in {sup 150}Tb. In addition, two new members of the {sup 149}Gd yrast cascade have been observed, extending the band to spin 135/2{h bar}. The results are discussed in terms of high-{ital N} intruder orbitals in the cranked-shell model.
