702 PROF. E. HULL ON THE DINGLE BEDS AND 
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 haying 
already been written on the subject by authors already quoted, as 
well as by the officers of the Survey. 
a. Dingle Section. (Figs. 1 & 2.) 
The whole series is admirably laid open in the coast cliffs extend- 
ing 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

a. Slates &e. with fossils (Wenlock). 
6. Beds of volcanic ash and lapilli, with felstone and bands of slate. 
c. Purple slate and brecciated beds. 
d. Fine-grained purple grits and slates, passing up into grey and yellow slates 
and calcareous sandstones with Ludlow and Weulock fossils. 
e, Grey and brown and purple slates and concretionary sandstones.

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 re- 
presentatives of the Wenlock beds up into the Glengariff grits of 
Mount Kagle 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 isas follows, adopting the designation of the beds 
as given by the Geological Survey :— 
Section in Dingle Promontory. 
(Beds in descending order.) 
Old Red Sandstone and Conglomerate resting discordantly on several of the 
underlying beds (Sybil Head, Kinard Hill, Bull’s Head, &c.).

ple grits, sometimes pebbly, and containing flaggy 
| and ripple-marked beds. 
\ 3, Purple and greyish slates with bands of grit inter- 
stratified.
