A germ (X, x) of a complex analytic hypersurface in Cd+l iS quasi-ordinary if it can be represented as the image of an open neighborhood of 0 in Cd under the map (s, Sd) (S , *-Sn d C n5, *(S, Sd)), n > 0, where 4 is a convergent power series. It is shown that the topological type of the singularity (X, x) C (Cd+l, 0) is determined by a certain set of fractional monomials, called the characteristic monomials, appearing in the fractional power series (tl / tIn) .
