Abstract
We derive an explicit formula for the connected -point functions associated to an arbitrary diagonal tau-function of the -BKP hierarchy using computation of neutral fermions and boson-fermion correspondence of type , and then apply this formula to the computation of connected spin double Hurwitz numbers. This is the type analogue of \cite{wy2}.
