Abstract
The gauge invariance of the covariant classical action of the Green-Schwarz superstring with Euclidean world sheet metric is examined. The action in terms of the Majorana-Weyl spinors is shown to exist only for the chiral model (type IIB). This action coincides with the one analytically continued from the Lorentzian metric when the Majorana condition is suitably modifed.
