In this paper the conditions under which the weighted generalized inversesA(1,3M), A(1,4N), AM,NDg andAd,W can be expressed in Banachiewicz-Schur form are considered and some interesting results are established. These results contribute to verify recent results obtained by J. K. Baksalary and G. P. Styan  and Y. Wei  and these extend their works.
