tected ; and as a large quantity of the clay has been examined the list from this 
locality gives a good record of the Foraminifera of the period. Nonionina arc - 
tica is not uncommon, now very rare as a British species, and only met with 
off our extreme Northern coast. 
8. Black Head.— Boulder Clay on the shore, half a mile N. of the Head. 
9. Gobbins, Islandmagee. — Boulder Clay on the shore, 1 mile South of the 
Headlands, 
10 &*i 1. BalJyrudder, 2 miles N.W. of Ballygally Head. — Bank of Boulder 
Clay, also Glacial Gravels underlying the clay ; both contain Foraminifera. 
12. Bovevagh Church, Co. Derry, near the village of Dungiven. — Fine 
Clay containing Turritella terebra in profusion j* Foraminifera abundant, espe- 
cially Lagenas. 
Killyleagh, near Shrigley, Co. Down. — No shells found. Foraminifera as 
follows : — Truncatulina lobatula , Globigerina bulloides , Nonionina depressula t 
and Discorbina globularis. Only a small quantity of the clay examined. 
Crumlin River, Co. Antrim, about midway between Crumlin and Lough 
Neagh. — A small patch of fine Clay a few yards in extent is here cut through by 
the Crumlin River. It contains very fragile examples of Mytilus edulis in pro- 
fusion. The following Foraminifera have been found : — Nonionina depressula % 
Globigerina bulloides , Discorbina globularis , and Textularia variabilis. Mr. E. 
T. Hardman, F.G.S., has— in a paper published by him in the “ Geological 
Magazine,” of Dec., 1876— stated that these beds are lacustrine and of Pliocene 
age. Since that paper was published, Mr. W. Swanston, F.G.S.,+ has made 
a careful examination of these clays, and the result has shown Mr. Hardman’s 
conclusions were incorrect, the beds in question being Marine Boulder Clay. 
Glacial Gravel beds occur at many places in the vicinity of Dublin. Three 
of these— viz. : Balscadden Bay, Ballybrack Station, and Ballyedmonduff— were 
visited by me in the Summer of 1879, and some of the gravels from each of 
these places brought away for examination. As no Microzoa have as yet been
