and these also are most numerous in the Muckruss and Killamey 

 hmestones. At the foot of the SUeve-meesh range, this lime- 

 stone includes Asaphus caudatus, Calymene macrophthalma, 

 and perhaps a third crustaceous animal, with Orthoceratites, EU 

 lipsolites ovatus, an Ammonite, Euomphalites, Turbinites, Neri- 

 tites, Melanites, and several species of Terebratula, Spirifer, and 

 Producta. Other bivalves in this locality are referrible to spe- 

 cies figured by Schlotheim, as from transition rocks on the con- 

 tinent. 



Near Smerwick harbour, similar organic remains are abun- 

 dant in slate, and fine grained grey wacke, together with hystero- 

 lites, and many genera of Polyparia, the whole resembling, both 

 in mineral and zoological characters, the rocks of Tortworth in 

 Gloucestershire, formerly described by the author, as well as 

 those of the Taunus in Nassau, more recently described by Sir 

 Alexander Crichton. Again, the same fossils are found in the 

 limestone of Cork, associated with impressions of vertebrae of 

 fishes; and analogous remains are to be met with also in a por- 

 tion of the slate of that neighbourhood. 



Transition Coal. — All the coal of the province of Munster, 

 except that of the county of Clare, is referrible to one of the 

 earliest periods at which that mineral has been produced ; the 

 true coal overlying the mountain limestone being found in that 

 county alone. At Knockasartnet, near Killamey, and on the 

 north of Tralee, thin beds of glance-coal, inclined at various 

 angles, from 70 degrees to verticality, are included in grey wacke 

 and slate. In the county of Cork, this old coal is more extensively 

 developed, particularly near Kantiirk, extending from the north 

 of the Blackwater to the Allow. The gorges of the latter river, 

 and various other neighbouring defiles, expose clay-slate, grey, 

 wacke, shale, and sandstone, in nearly vertical beds, direct from 

 west to east. This transition tract extends to the river Shannon 

 on the north-west. As the systems range from west to east, in 

 a series of parallel acutely-angled troughs, the beds have great 

 diversity of inclination, dipping rapidly either to north or south, 

 and bending horizontally between the ridges. This glance-coal 

 or anthracite is raised in sufficient quantities for the purpose of 

 burning the limestone of the adjoining districts ; and the most
