are in a decomposing state for two or four inches inwards from 
the surface of the crack, and in this part of the rock are found 
the most beautiful fossils, of a purely white colour, with all their 
most delicate markings, in a high state of preservation. The 
pores of fenestellge, and the finest striae ofpectens are seen under 
the magnifier. Producta latissima is abundant here, though 
scarce in other localities. 
Kilmacduagh, in Clare, is five miles S.W. of Gort. Fossils are not 
plentiful in the limestone here. 
Kilmallock, in Limerick, is a limestone locality. There are large 
quarries in the vicinity, and the usual fossils of the limestone 
come out in abundance, and show the markings uncommonly 
well. 
Kilmore, in Armagh, is six miles N.E. of the town of Armagh. 
The dip of the limestone, which is fossiliferous here, is about 
15° N.W. 
Kiltullagh, in Roscommon, is eight miles S.W. of Castlereagh. 
The lower part of the limestone is the rock here. 
Knockagh, in Louth, is three miles N.W. of Dundalk. The rock 
is limestone with shale, interstratified near the base of the lime¬ 
stone subdivision of the Carboniferous system. 
Knocknarea, in Sligo_ See Culleenamore. 
Knockninny, in Fermanagh, is a steep high hill, on the west side of 
Lough Erne, ten miles south-east of Enniskillen. The rock is a 
light gray limestone, and it contains here some beautiful fossils, 
especially Fenestellas, on the west side, half way up the hill. 
Knockonny, in Tyrone, is half a mile north of Ballygawly. A yel¬ 
lowish calcareous slate occurs here, in a stream in which a pecu¬ 
liar Pecten is abundant, and no other fossil. It has been called 
Pecten Knoclconniensis from this place. 
Lackagh, in Tyrone, is one mile west of Drumquin. In the low 
part of this townland, near the bridge, limestone occurs, which 
yields beautiful specimens of Producta hemispherica. 
In the high part, or western end, is a ravine called Glenbane, 
in which a stream has made a deep cut in the black shale; this is 
one of the best localities in Ireland for fossils. I believe these black 
strata to be the millstone grit, or lower part of the coal forma¬ 
tion. On the banks of this stream, if the grass and soil be dug 
away, near the top, the rock is soon laid bare, and this upper 
decomposing part of it yields the finest casts of fossils, which come
