The integrated 21 cm H I emission in the field of Hydra II from the GASS survey (McClure-Griffiths et al. 2009; Kalberla et al. 2010) over 20 km s-1 around the stellar velocity of Hydra II, whose location at 
is marked with the circle. No significant emission is detected. The brightest H I within a degree of the galaxy is consistent with a 2.3σ noise feature.
