ALPHABETICAL LIST OF LOCALITIES. 
Abbeylands, in the county of Donegal, is about one mile N.W. of 
the town of Ballyshannon, on the north bank of the river Erne. 
The rock here is calcareous slate, and the fossils are found in 
abundance and variety along the shore. The black shale is in- 
terstratified with thin beds of gray limestone; some beautiful 
specimens of Orthis jiliaria are found, and a few of the limestone 
beds contain a variety of Orthis crenistria ( umhraculum?) four 
inches in diameter. 
Aghaboy, in the county of Cavan, is situated about a mile and a 
quarter S.W. of Swanlinbar village. The upper part of the lime¬ 
stone occurs here, and there is a cave, called Pulgulm, or the Pi¬ 
geon-hole, from which a subterranean mountain stream emerges, 
about which there are some fossils. In this cave the surface of 
the limestone has a high degree of polish, probably from the fric¬ 
tion of particles contained in the muddy waters which flow 
through it in floods, and which flow down from the sandstone and 
argillaceous strata of the coal rocks. 
Aghafin, in the Queen’s County, is one mile S.W. of the village of 
Castletown, and four miles S.W. of Mountrath; a black calcareous 
slate occurs here, which is full of fossils. 
Aghamore, in Leitrim, lies five miles S.W. of Ballyshannon, and about 
two miles S.W. of Bundoran. In a stream, at the western bound¬ 
ary of this townland, about fifteen chains south of the road, and 
at the base of the steep part of the mountain side, a fine black 
shale occurs, in the calcareous slate in which many species of 
shale fossils are found, such as Sanguinolites, Amphidesma, Lu- 
cina, Nucula, &c., and some of the beds have great numbers of 
Cythere. 
Aghintain, in Tyrone, is two miles west of Clogher. The fossili- 
ferous rock is black shale, which is found in the river which flows 
through the townland, and in some quarries. 
Aghnaglogh, in Tyrone, two miles N.W. of Clogher. A river runs 
through this townland, in which occurs a black shale in connex¬ 
ion with the sandstone. Some black, hard, calcareous beds are 
found in this, about two feet above the level of the water, at a
