NOTES ON THE STRATIGRAPHICAL RELATIONS OE THE SEDIMENTARY ROCKS 
OE THE SOUTH OE IRELAND J WITH SPECIAL REFERENCE TO THE POSITION 
OF THE STRATA OE WHICH THE GLENGARRIEF AND DINGLE DISTRICTS ARE 
COMPOSED, IN COMPARISON WITH CERTAIN DOUBTFUL CLASSES OE ROCKS IN 
THE NORTH OE IRELAND. BY RICHARD GRIFFITH, LL. D., E. G. S. LONDON 
AND DUBLIN. 
In preparing the several editions of my GeologicalMap of Ireland, includ¬ 
ing the last, I have found great difficulty in deciding on the class of 
rocks to which several extensive districts, situate in different localities 
in the country, ought to be attached. These districts are chiefly com¬ 
posed of brown and reddish-brown grits and conglomerates, some of 
which are quartzose, and some porphyritic, and these rocks are occa¬ 
sionally interstratified with gray and greenish-gray chloritic grits, al¬ 
ternating with purplish and brownish-red shales, and in a few instances 
with reddish limestone and with purple slates, having a regular cleav¬ 
age in the south. 
The most northern district consisting of these rocks occupies an ex¬ 
tensive area in the counties of Tyrone and Fermanagh, extending in a 
south-western direction from the neighbourhood of Pomeroy in the 
county of Tyrone, to the north-eastern boundary of Lough Erne in the 
county of Fermanagh, and in a northern and southern direction from the 
town of Omagh to the village of Ballygawley, in the county of Tyrone, 
comprehending an area altogether of about 300 square miles. 
The second district belonging to this series of rocks is situate in the 
counties of Eoscommon, Sligo, and Mayo, where it forms a ridge of 
hills known by the name of the Curlew Mountains, forming a range of 
about thirty-two miles in length, the character of the strata being identi¬ 
cal with those of the district situate to the north-east of Lough Erne, 
already mentioned. 
The third district, composed chiefly of reddish-brown grits, is situate 
in the county of Mayo, and extends in an eastern and western direction 
from Lough Conn, along the north shore of Clew Bay, nearly to Achill
