Others are the solar mass splitting {\\em vis-\\`{a}-vis} the atmospheric one and the deviation of $\\theta_{23}$ from maximal mixing. In this talk we elaborate on a neutrino mass model based on the see-saw mechanism in which the mixing angles to start with are either vanishing ($\\theta_{13}$ and $\\theta_{12}$) or $\\pi/4$ ($\\theta_{23}$). The atmospheric mass splitting is taken as a part of this initial structure but the solar splitting is absent.
