of S. ; considerably smoothed and scratched. 17 per cent, were 

 erratics. No shells found, but five species of Foraminifera ; one 

 redeposited fossil, a Belemnite. Photographs obtained of the 

 quarry, which include 60 yards of its length. 



Erratics. — Mica schist, metamorphic district of Co. Antrim, 

 N. by W. Quartzite, metamorphic, like pebbles of Lr. Old Red, 

 Cushendun, N. by W. Chert, probably Carb. of Ballycastle, 

 N.N.W. Indurated chalk, chalk and flints, Co. Antrim. Trias 

 marl, Co. Antrim. Laterite, Co. Antrim. Silurian grits, Co. 

 Down, S., or Scotland, N.E. Micaceous sandstone, Co. Down, 

 S. Carboniferous limestone shales, Co. Down, S. Mudstone, 

 Co. Down, S. Dolerite, Ulster. Basic Felstone, Ulster. Eurite 

 with Riebeckite, Ailsa Craig. 



VIII. — WOODBURN. 



Parish of St. Nicholas, Carrickfergus, Co. Antrim. More 

 than a mile N.W. from Carrickfergus, 166 feet above sea level. 

 Below the range of hill encircling the Lough. Boulder clay 

 exposed in banks of Woodburn river ; base not visible, but 

 probably resting on Trias, as fragments of bright red are seen 

 towards the visible base of cutting. Depth exposed measured 

 at Duncrue Scutch Mill was 13 feet 8 inches. The present 

 course of the river has cut through an older wider river bed 

 with gravel deposit, whose banks were also formed of boulder 

 clay. General course of the river N. by W. Clay tough, dark 

 red, unstratified, with abundant boulders. Long axis a little 

 W. of N. and S. of E., striated, smoothed, and rather rounded. 

 Redeposited fragmentary Greensand fossils found. Shells — 

 * Mytilus edulis, Nucula nucleus, Leda pygmea, almost invariably 

 perfect ; Leda minuta, almost invariably perfect ; Leda Pernula, 

 Astarte sulcata, AstarU comj>ressa, Saxicava rugosa, var. 

 arctica, Trophon latericeus. 50 species of Foraminifera were 

 formerly found, but the bed below Woodburn Bridge, formerly 

 so rich in relics of marine life, is now covered with grass and 

 rubbish. If the Trias be accepted as the underlying rock, all 

 the boulders counted were erratics.
