  This paper completes investigation of symmetry properties of nonlinear
variable coefficient diffusion-convection equations of the form
$f(x)u_t=(g(x)A(u)u_x)_x+h(x)B(u)u_x$. Potential symmetries of equations from
the considered class are found and the connection of them with Lie symmetries
of diffusion-type equations is shown. Exact solutions of the Fujita--Storm
equation $u_t=(u^{-2}u_x)_x$ are constructed.
