Abstract: 
 Lim and Xu [4] established a fixed point theorem for
 uniformly Lipschitzian mappings in metric spaces with uniform
 normal structure. Recently, Huang and Hong [1]  extended
 hyperconvex metric space version of this theorem, by showing a
 common fixed point theorem for left reversible uniformly
 $k$-Lipschitzian semigroups. In this paper, we extend Huang and
 Hong's theorem to metric spaces with uniform normal structure.
