LOCALITIES OF IRISH CARBONIFEROUS FOSSILS.

Countenan, in Cavan, is four miles east of the town of Cavan, and 
one mile N.W. of the village of Stradone. A large quarry here, 
in an arenaceous limestone, affords a good variety of fossils. 
Courtlough, in Dublin, is three miles south of Balbriggan. A 
large quarry has been opened here near the base of the coal for¬ 
mation, which contains some of the shale fossils of that division 
of the Carboniferous rocks. 
Cove, in Cork, now Queenstown, is a seaport town in Cork Har¬ 
bour. In a black slate, immediately west of the town, Loxoceras 
incomitatum is found. It appears to me very doubtful that this 
slate belongs to the Carboniferous rocks. 
Cregg, in Meath, is two miles north of Nobber. The limestone here 
has many beautiful varieties of fossils. 
Cregganore, in Galway, more commonly known by the name of 
Toberelathan is on the N.W. brow of the Derrybrian mountains, 
six miles S.W. of Loughrea, and two furlongs east of the Gort 
road. There is a junction visible here, in a stream of the Old 
Red Sandstone, lying unconformably on the gray wacke slate, and 
a little higher on the hill are several junctions, showing patches 
of yellowish conglomerate on the slate; and in some places, a 
few perches of the lower bed or two only; near the well called 
Toberelathan, in the stream, the blackish calcareous slate appears; 
the lowest slate of the Carboniferous rocks, which is full of the 
usual fossils, especially Spirifer attenuata and Leptagonia analoga. 
Crevenish, in Fermanagh, is one mile S.W. of Kesh, on the eastern 
shore of Lough Erne. This is a good fossiliferous district. 
Croppatrick, in Mayo, is one mile S.E. of Killalla. The arenaceous 
limestone here is fossiliferous. 
Cruicetown, in Meath, is two miles west of Nobber. 
Cuilmore, in Mayo, is three miles east of Claremorris. Calcareous 
slate, with limestone, here has the usual fossils. Fenestellae 
are abundant. 
Culleenamore, in Sligo, is five miles west of Sligo, on the western 
side of Knocknarea mountain. This place is remarkable for the 
abundance of specimens of Syphonophyllia cylindrical, which are 
found in the fields, as they are disintegrated by the weather from 
the limestone cliffs of Knocknarea, and roll down the side of the 
hill. Some of those are three or four inches in diameter, and the 
pieces a foot long; but the whole fossil, as found at Kilglass, on 
the sea-shore, is two feet long.
