We construct a hierarchy of supersymmetric string theories by showing that the general [ital N]-extended superstrings may be viewed as a special class of the ([ital N]+1)-extended superstrings. As a side result, we find a twisted ([ital N]+2) superconformal algebra realized in the [ital N]-extended string.
