In the spectrum of the quasar PKs 2020--370 (z/sub em/ = 1.050), we find Ca II absorption lines both at near zero redshift and at z/sub abs/ = 0.02865 +- 0.00007. The latter is closely similar to the redshifts of two galaxies in the group Klemola 31, which are nearby on the plane of the sky. This observation adds to the evidence that the narrow-lined heavy-element absorption systems in quasar spectra in general arise in the extended halos of intervening galaxies.
