lie at the $\phi=\pi$ semicircle. First, we shall consider the solutions interpolating amongst vacua $\theta_i$ in the interval $[0,\pi/2)$. It is expected that there should be a one parameter family of solitons that interpolate between the source $\theta_{4q+1}$ and the sink $\theta_{4q+3}$, and the same source and the sink $\theta_{4q-1}$. There also should be a unique soliton interpolating between the source $\theta_{4q+1}$ and the saddle $\theta_{4q}$, and the sink $\theta_{4q+3}$ and the saddle $\theta_{4q+2}$. In addition to these solutions, we have the solitons that lie on the maximal torus. $$\vbox{
