5. Magheramome — Estuarine Clay on the West shore of Larne Lough— 

 An extensive bank of this clay occurs along the shore, a few hundred yards 

 south of the ferry-slip, close to the railway station. Lagena striato-punctata, 

 now one of our rarest British Lagenas, occurs here in abundance, as also at 

 Limavady Junction. Shells and Foraminifera are abundant. 



6. Blackstaff Bridge, Strangford Lough, on Blackstaff River, about two 

 miles South of Kirkcubbin and East of the road to Portaferry. 



7. Limavady Junction, Lough Foyle — Estuarine Clay slightly above high 

 water, close to the railway station. To Mr. Gray is due the credit of being 

 the first to discover Estuarine Clay at this place, as also at Blackstaff Bridge. 

 The clay is exceptionally rich in Foraminifera. A few Polycistinae were found 

 here.
