We show how to map the Belavin-Polyakov instantons of the O(3)-nonlinear
$\sigma-$model to a dual theory where they then appear as nontopological
solitons. They are stationary points of the Euclidean action in the dual
theory, and moreover, the dual action and the O(3)-nonlinear $\sigma-$model
action agree on shell.
