702 those in the neighbourhood of Killarney, next those of Kenmare, and lastly those south of Glengariff. I shall briefly describe the results of our examination of these districts in the order above named. A detailed description will be unnecessary, so much having already been written on the subject by authors already quoted, as well as by the officers of the Survey.

The whole series is admirably laid open in the coast cliffs extending from Sybil Point to Slea Head, a distance of six miles. The bottom beds are probably of Llandovery age, upon which follow representatives of the Wenlock and Ludlow beds as far as Clogher Bay. Owing, doubtless, to a large fault, these beds are repeated to the south of Clogher Head, where they form a section of a dome or inversion, as represented on the horizontal section prepared by Mr. Du Noyer. Nevertheless from Carrigcarn, opposite Carhoo, southwards there is an unbroken section commencing with the representatives of the Wenlock beds up into the Glengariff grits of Mount Eagle and Slea Head, which strike across the intervening sound into Great Blasket Island. This section, which has been very carefully measured and observed, shows a thickness of about 10,000 feet of strata, and is as follows, adopting the designation of the beds as given by the Geological Survey:—

Old Red Sandstone and Conglomerate resting discordantly on several of the underlying beds (Sybil Head, Kinard Hill, Bull's Head, &c).
