We examine a sample of 30 edge-on spiral and S0 galaxies that have boxy andpeanut-shaped bulges. We compute model stellar kinematics by solving the Jeansequations for axisymmetric mass distributions derived from K-band images. Thesesimple models have only one free parameter: the dynamical mass-to-light ratio,which we assume is independent of radius. Given the simplicity of the modellingprocedure, the model second velocity moments are strikingly good fits to theobserved stellar kinematics within the extent of our kinematic data, whichtypically reach ~ 0.5-1 R25 (where R25 is the optical radius), or equivalently2-3 Re (where Re is the effective or half-light radius). We therefore find noevidence for a dominant dark matter component within the optical disk of spiralgalaxies. This is equally true of the S0s in our sample, which significantlyextends previous observational constraints on dark matter in these galaxies.The predicted kinematics do deviate slightly but systematically from theobservations in the bulge region of most galaxies, but we argue that this isconsistent with the claim that boxy and peanut-shaped bulges are bars viewededge-on.
