We extend our study of neutrino masses and mixings to the case of a 17-keV Dirac {tau} neutrino, which has reappeared in recent {beta}-decay experiments. A special set of Dirac submatrices is inputted which works well for quarks and yields a top-quark mass near 135 GeV. Unlike our previous Majorana neutrino study, however, we cannot simultaneously explain all the data including the 17-keV neutrino, its small {vert bar}{ital V}{sub {nu}{tau}}{ital e}{vert bar}{sup 2}=0.0085 coupling to the electron, the present accelerator neutrino oscillation bounds, and the preferred solar-neutrino nonadiabatic Mikheyev-Smirnov-Wolfenstein effect interpretation.
