A classic region of band termination at high spin occurs in rare-earth nuclei with around ten valence nucleons above the
146 Gd closed core. Results are presented here for such non-collective oblate (γ = 60°) terminating states in odd-Z155 Ho, odd-odd156 Ho, and even-even156 Er, where they are compared with neighbouring nuclei. In addition to these particularly favoured states, the occurrence of collective triaxial strongly deformed (TSD) bands, bypassing the terminating states and extending to over 65ħ, is reviewed.
