Twenty six specimens of this species have been collected on Great Exuma , Andros , Bimini , and Eleuthera islands in the Bahamas from 1962-1993 but only two specimens afterwards. Based upon the number of specimens collected, we believe this species is established in the Bahamas . This species may have rafted on flotsam with favorable ocean currents from Cuba . Iturralde-Vinent and MacPhee (1999) concluded that the effect of surface-current flow as a dispersal agent, while generally from the southeast to the northwest in the present-day Caribbean Sea, has not always been so, because surface-current patterns have changed radically with the formation of the islands of the West Indies and the closure of the isthmus of Panama . Given those constraints, it is reasonable to conjecture that the occurrence of S. ajax in the Bahamas is a relatively recent, geologically, event. The short distance between Cuba and the Bahamas , hence the brief over-water dispersal time, would favor survival of rafting, salt-intolerant animals. Andros , San Andros , 16 August 1977 , J. W.
