Excitons have recently been shown to deviate from pure bosons at densities a
hundred times smaller than the Mott density. The corresponding calculations
relied on the unscreened excitonic ground state wavefunction. A consistent
inclusion of screening, by use of the fundamental eigenfunction of the
Hulth\'{e}n potential, vindicates this approximation.
