We report on the discovery of HI in absorption toward the gigamaser galaxyTXS2226-184 using the VLA. The absorption appears to consist of two components-- one with a width of 125 km/s, and one broader (420 km/s), both toward thecompact radio source in the nucleus of the galaxy. Based on these largevelocity widths we suggest that the HI absorption is produced in the centralparsecs of the galaxy, on a similar scale to that which gives rise to the watermaser emission. This brings to eight the number of galaxies known to exhibitboth water masers and HI absorption. We explore the relationship between thesetwo phenomena, and present a physically motivated (but unfruitful) search forwater maser emission in five radio galaxies known to exhibit strong HIabsorption.Comment: 19 pages including 5 figures, LaTeX, Accepted to Ap
