  Solvable vertex models in two dimensions are of importance in conformal field
theory, phase
  transitions and integrable models.
  We consider here the $D_n$ spin vertex models, for $n$ which is odd.
  The models involve also the anti--spinor representation. We describe here the
Boltzmann weights
  for these representations using crossing symmetry from the previously known
spinor representations.
  For calculation reasons we limit ourself to the $n=3$ and $n=5$ cases, which
are described
  explicitly.
