Specimens of CucuUcea and Curtonotus were found at several lo-calities (see Explanation of Sheet 187, p. 17, of the Irish SurveyMaps), but always in grits, the situation of which showed them tobe low down in the Carboniferous Slate. One very good locality forthose shells is in a small quarry on the south side of the lane leadingwestwards to Coolkirky House, near the hill top. The fossils occuras casts in a band of brown sandstone, about 4 inches thick, whichis almost made up of them, though similar beds both above andbelow do not show a single shell. Those sandstones are interstra-tified with beds of grey slate, all dipping north at 65° (lb., pp. 54,55). This occurrence of these Conchifers in vast abundance in somethin bands, and their total absence through great thicknesses of rock,is what takes place also in Devonshire, as I saw in the quarries nearBraunton. Fig. 8.—Section near Ballinhassig. Length of Section, about 3 . Probably Coal-measures. d^. Carboniferous slate with Coomhola grits in lower Old Ked Sandstone, red slates and grits. In fig. 8 we have a section on the flanks of the same Old EedSandstone ridge as that shown in fig. 7, and across the same valleyof the little* Owenboy river, but a few miles farther west. The Old Red shows thick red sandstones and purple slates un-dulating in various directions, but chiefly to north and south, andfinally dipping south at a high angle, the upper beds having muchgreen slate interstratified with the red. South of these, strong yeUowish-brown sandstones and greenish-grey and yellow flagstones and shales show themselves in the rail-way-cutting, and elsewhere, dipping south at 70°, and still farthersouth, about the railway tunnel, greenish-grey grits and grey slatesundulating in many regular arches and troughs, but on the wholedipping south.
