New observations made with the Westerbork Synthesis Radio Telescope of M31 in the line of neutral hydrogen (Brinks, this volume) show the presence of high-velocity HI in the inner 4–5 kpc of the galaxy. There were indications from previous 21-cm line studies that HI gas is moving with peculiar velocities (Whitehurst and Roberts, 1972; Unwin, 1979) but the new maps, made with a resolution of δα × δδ × δV = 24″ × 36″ × 8.2 km s−1 and sufficient sensitivity show for the first time the distribution of this material.
