6. The Zone of Belemnites acutus. — In the small bay of Ballintoy, 

 the base of the White Limestone is conglomeratic, and measures 

 1 foot in thickness ; it rests on black micaceons clays, with some 

 calcareous nodules and numerous specimens of Belemnites acutus. 

 The majority of the fossils, principally Ammonites enclosed in cal- 

 careous nodules, which are offered for sale at the Giant's Cause- 

 way, are obtained during the winter on the shore at Ballintoy; 

 these I have no doubt are derived from submerged beds of this zone.
