The Oppenheimer-Volkoff equations for isothermal, partially degenerate neutral lepton configurations have been solved numerically for arbitrary temperature and degree of degeneracy. For the specific case where the leptons are massive neutrions (approx.30 eV) with properties quite tightly constrained by cosmological considerations, we find that it possible to have a neutrino halo surrounding a normal galaxy with the right values of mass and radius required of the ''invisible halo'' in the missing mass problem. The density distribution, however, yields a rotational curve which, with the present chosen values of parameters, does not fit the observations for spiral galaxies.
