Greg,

Use EdgeForm[] as the fourth item in your parametric representation. The book isn't
too clear on this, but you can put a plotting directive, or list of plotting
directives in that position. Here is an example.

ParametricPlot3D[{Cos[t]*(3 + Sin[u]), Sin[t]*(3 + Cos[u]), Sin[u],
    EdgeForm[]}, {t, 0, 2*Pi}, {u, 0, 2*Pi}, Boxed -> False,
   Axes -> False, PlotPoints -> {40, 21}];
