  Based on a new approach to quark and lepton masses, where the mass spectra
originate in vacuum expectation values of O(3)-flavor 1+5 (gauge singlet)
scalars, a neutrino mass matrix of a new type is speculated. The mass matrix is
described in terms of the up-quark and charged lepton masses, and, by assuming
a special flavor basis, it can be accommodated to a nearly tribimaximal mixing
without explicitly assuming a discrete symmetry. Quark mass relations are also
discussed based on the new approach.
