We report the observation of an unexpected magnetic transition in the Kondo semimetal CeNiSn under uniaxial pressures. For Pia , both the specific heat C and magnetic susceptibility x decrease steadily with increasing P. By contrast, once Pib and Pic exceed 0.13 GPa, C(T) exhibits a distinct jump at 4 K followed by a peak at 3 K. The concomitant peaking in x(T) for PiBic is indicative of an antiferromagnetic transition. @S0163-1829~99!51234-4#
