The above works, but I'm not sure why you have to do what you do in the constructor. It may be slightly brittle, but we create a separate controller that we include in last. Its last so that the splat route is the last one to match:

NotFound = Backbone.Controller.extend({

  routes: {
    "*path"  : "notFound"
  },

  notFound: function(path) {
    var msg = "Unable to find path: " + path;
    alert(msg);
  }

});

new NotFound();

Using a more robust version of the above seems a cleaner approach to me.
