Complete light curves in B and V, and less complete in U, have been obtained for the ellipsoidal variable 33 Tauri. An iterative procedure applied to the combined photometric and spectroscopic data gives i = 59°.0, a = 13.43 R_sun;, R1 = 4.78 R_sun; and q = 0.414, and these provided input to more detailed model calculations. Models which reproduce the observed light variations have been computed using the Wilson-Devinney code and Hill's LIGHT program. Lack of independent information about the secondary precludes determination of a definitive solution, but a preliminary "best" model is identified. Shallow eclipses are predicted to occur.
