Abstract: In this note, we give an example of a diffeomorphism *f* on a three dimensional manifold *M* such that *f* has a property called quasi- Anosov but such that *f* does not have a hyperbolic structure (is not Anosov). Mañé has given a method of extending *f* to a diffeomorphism *g* on a larger dimensional manifold *V* such that *g* has a hyperbolic structure on *M* as a subset of *V*. This gives a counterexample to a question of M. Hirsch.
