McElroy (1983) has recently provided an extensive set of radial velocity measurements for the stellar mean motions in the bulge of M31. These velocities show a surprisingly bumpy pattern. It is frequently postulated that the absorption clouds in the bulge are the cause of these observed velocity bumps. If this postulate is correct, further improvements of the velocity measurements will be futile and their use as a dynamical diagnostic minimal. To test this pessimistic hypothesis, the effects of the observed dust clouds on the velocity observations have been analyzed. Fortunately the observed clouds cannot be the main cause of the bumps in the observed velocities. Furthermore, a statistical analysis of the present velocity observations strongly suggests the existence of unidentified systematic errors which might explain the apparent bumps.
