Let T be a Fuchsian group of signature (p,n,m; u\, 1/2,. •. ,vn)\ 2p-2 + m + 5Z"_, (1-l/fy) > 0. Let I\, h, ■ ■ ■, Im be a maximal set of inequivalent components of f! n R; O is the region of discontinuity and R is the extended real line. Let be a quadratic differential for T. Let / be a solution of the Schwarzian differential equation Sf = . If 4> is reflectable, / maps each Ij into a circle C¡. For each-7 er there is a Moebius transformation x(l) such that / o-y = x(l) ° /■ We prove that ¡p is determined by the homomorphism X and the circles C\, C2, ■ ■ ■, Cm.
