LOCALITIES OF IRISH CARBONIFEROUS FOSSILS.

Castletown, in Meath, is four miles south of Trim. The light 
gray limestone here abounds in fossils. 
Cavansallagh, in Tyrone, is two miles N.W. of Drumquin. The 
limestone here has several varieties of fossils. Specimens of Si- 
phonophyllia cylindrica are found, exactly like those got at Car- 
lingford. 
Chicken Hill.— See Killmallock. 
Claraghmore, in Tyrone, is one mile and ahalfN.E. of Drumquin. 
Casts of Bellerophon apertus and Cornu arietis occur here in beds 
of arenaceous limestone, which is impure and very siliceous. 
Clare, in Tyrone, is half a mile east of Cookstown. Very beautiful 
specimens of Liihostrotion striatum are found here. 
Clareview, in Fermanagh, is two miles S.W. of Kesh, on the east 
shore of Lough Erne. 
Cleen, in Roscommon, is four miles N.E. of Boyle, and one mile from 
Knockvicar bridge. Arenaceous limestone occurs here, which 
has many of the fossils of the lower beds of the Carboniferous 
limestone. 
Cleenishgarve, in Fermanagh, is an island in Lough Erne, about two 
miles S.W. of Kesh. The rock consists of the alternating slates 
and limestones of the lower part of the Carboniferous limestone. 
Clifden, in Clare, is one and a half miles west of Corofin, is a mill¬ 
stone grit locality. In the road side, in a wood, the black slaty 
strata are exposed, and yield pectens, posidonice , &c. 
Clone a, in Waterford, is three miles N.E. of Dungarvan, on the sea¬ 
shore. The calcareous slate, interstratified with beds of lime¬ 
stone, occurs here, as at Ballinacourty, and contains an abun¬ 
dance of fossils. The rock here, which dips 20° south, is probably 
the counterpart of that at Ballinacourty, which dips the reverse 
way, or northward, both being the lower slates and limestone 
beds of the valley of Dungarvan, over which rests the pure light 
gray limestone of Ballinacourty, Ballyduff, and the whole valley 
of the Blackwater, to Lismore and Fermoy. That which is shale 
in other localities, as at Hook Head, is here slate, from the distinct 
cleavage which it exhibits in this valley. All the lower and im¬ 
pure shales of the south of Ireland, beyond a certain line, show 
a cleavage, which is not seen to the north of that line, which 
cleavage appears to be connected with the distortion of the fossils 
imbedded in it. The line above alluded to extends from this
