 These beds are separated from the Supra-Conglomerate Limestones by the 

 entrance to Rush Harbour. Matley says " it seems probable that there is a 

 strike fault here, though of no great throw."' 



The evidence now obtained shows that the brachiopod faunas north and 

 south of the gap are nearly identical. We may take it then that the horizons 

 cannot be far apart.
