Newcastle, in Tipperary, is eight miles east of Clogheen. The 
rock is dark-coloured slate, and fossiliferous. 
Old Leighlin is in Carlow, seven miles S.W. of Carlow, and two 
miles west of Leighlinbridge. The limestone occurs here, and 
at its junction with the overlying millstone grit of the Castle- 
comer district, fossils are numerous, and some beautiful casts 
are found in old excavations, where the flinty limestone has been 
exposed to the weather. 
Oldtown is in Dublin, one mile and a half N.W. of Swords. The 
limestone, of a light gray colour, shows itself here, and contains 
a good variety of the usual fossils. Euomphalus pentangulatus is 
abundant. 
Oughterdrum is in Fermanagh, three miles S.E. of Relleek, and 
six S.E. of Ballyshannon. The limestone occurs here, and is, as 
usual, fossiliferous. 
Paget Priory, in the townland of Mullagh, is four miles north 
from Kilcock. It is a locality of black slates of the millstone 
grit, and contains Posidonise and Goniatites. 
Poulscadden, in the county of Dublin, comprises a little of the 
shore and rocks at low water, immediately south of Howth Har¬ 
bour. The rock is calcareous slate, and has abundance of the 
usual fossils. The beds under high water are decomposed for 
nearly a foot inwards from the surface, and the fossils come 
beautifully marked out of them. 
Prughlish, in Tyrone, is three miles west of Drumquin. This is 
a black shale district, in millstone grit, which contains the usual 
fossils abundantly. 
Rahan’s Bay is in Donegal, on the sea-shore, one mile S.W. of 
Dunkineely village. The rocks here are exposed to the action 
of the waves, and yield an abundant supply of fossils. There 
are sandstone, some limestone, and much black shale. 
Raheendoran, in Carlow, is four miles S.W. of Carlow. The up¬ 
per part of the limestone here yields some fossils. It is exten¬ 
sively quarried for tombstones and architectural work. One 
of the beds contains Producta hemispherica and Producta co- 
moides , and the quarrymen call this the half-moon bed. Other 
fossils are found, but not plentifully. 
Rahoran, in the county of Tyrone, is two miles north of Fivemile- 
town. The fossils of the black shale here are got out in the 
finest state of preservation, and are very abundant, Pterinea
