We report a deep search for HI 21cm emission from the sub-DLA toward PG1216+069 with the Giant Metrewave Radio Telescope. No emission was detected and our upper limit on the mass of any associated galaxy is , nearly 3 orders of magnitude less than . The absorber is thus the most extreme known deviation from the standard paradigm in which high column density quasar absorption lines arise in the disks of gas-rich galaxies.
