Recent observations of rotation curves of spiral galaxies in clusters made by Rubin et al. (1988), Whitmore et al. (1988) and Forbes and Whitmore (1988) are analyzed. It is found that spiral galaxies in the inner region of clusters appear to have falling rotation curves and M/L gradients which are flatter than for galaxies in the outer regions of clusters. Problems encountered in attempts to construct mass models for cluster galaxies are briefly discussed. 18 refs.
