BOULDER CLAY LOCALITIES. 



1. Water Works, Belfast.— In excavating for the Clear Water Basin, in 

 1841-3, Boulder Clay was exposed, containing an abundance of shells, many of 

 them water-worn. * The only material examined for Foraminifera was a little 

 of the clay washed out of a few specimens of Buccinum undatum. Six species 

 were found in this way, and considering the very small quantity of the clay 

 examined, it may be considered fairly rich in Foraminifera. 



2. Falls Park, Belfast, about 3 miles from the town, on the Falls Road. — 

 Boulder Clay cut through by a small stream that flows through the Park. Mr. 

 Stewart was the first to discover fossils at this place. The discovery was of 

 special interest, as the clay contained several shells not usually met with in 

 Boulder Clay, and in this respect appears very similar to the clay excavated 

 some years ago in making the new basin at the Water Works locality, but 

 which is not now accessible. 



3. Castle-Espie, Co. Down. — Three miles from Comber, on the shore of 

 Strangford Lough. —Thick beds of Boulder Clay resting on Carboniferous Lime- 

 stone at the quarries and pottery works. The surface of the limestone is beauti- 

 fully polished and grooved with ice action. 



4. Cherry Valley, near Comber. — Cliffs of Boulder Clay, on the shore of 

 Strangford Lough, 1 mile S.E. of Comber. No shells found, Foraminifera rare. 



5. Ballyholme Bay, Co. Down, half amileN.E. of Bangor. — Bank of 

 Boulder Clay on the shore now covered by a sea-wall. Very little of the clay 

 examined. 



6. Knock Glen, Co. Down, near the Knock Railway Station. — Cliffs of 

 Boulder Clay in the Glen, cut through by the stream Conswater. Shells rather 

 rare, Foraminifera plentiful. 



7. Woodburn Glen, I mile N.W. of Carrickfergus, Co. Antrim. — High 

 banks of Boulder Clay at the side of the river Woodburn between the bridges. 

 Leda pernula and minuta, with both valves attached, are not unfrequent. 

 The clay here contains Foraminifera in great profusion j 50 species were de-
