Vol. 58. | THE FOSSILIFEROUS SILURIAN BEDS OF KERRY. 23d 
A (28). Opposite the little island of Carrigcam the series is cut off 
by a fault running in a general east-north-easterly and west-south- 
westerly direction. In its neighbourhood the beds are much dis- 
turbed, but beyond it the same general strike is maintained. At 
. the top of the cliff, to the west of this fault, a band of bluish rhyolite 
(A 28) is well exposed. This band, with some overlying ashes and 
sandy beds, is also well exposed in the ravine which, crossing the 
high road, strikes the coast a little north of Carrigcam. 
A (30). The sections of the ashy conglomerate show it to contain 
well-marked rounded lapilli—not only of rhyolitic, but also of 
andesitic rocks. 
A (31). These beds are identical in general character with (A 27). 
They occupy most of the bay between Owen and Carrigcam, and 
have yielded :— 
Alveolites Labechii, M.-Edw. | Fenestella sp. 
Spirifer bijugosus, M‘Coy. | Pterinea sp. 
Sp. elevatus, Dalm. | Hortostoma globosum, Schloth. 
Stropheodonta imbrex, Pander, 
var. seniglobosa, Dav. 
Mr. F. R. C. Reed says, with regard to the bands (A 31) and 
(A 27), that there is nothing in the fossils to prevent the ocean 
of a Wenlock age to the beds. 
The little 10-pole island, east of the peninsula south of Owen, 
has its eastern half formed cf the fine ashes (A 33), and its western 
fialf of the coarse ash (A 34). 
A (35) is an extensive exposure of fine-grained blue rhyolite, 
forming the whole of the peninsula south of Owen. Its base is not 
seen ; it 1s impossible, therefore, to estimate the thickness of the 
rhyolite, which is very considerable, probably not less than 150 feet. 
(6) The Coast-Section from Coosmore to Owen. 
This part of the coast-section includes the promentory of Clogher 
Head, and (we believe) forms the middle limb of a great S-shaped 
fold which has been overfolded to the north and thrust over the 
northern limb. (See fig. 1, p. 228.) The newest, but, owing to the 
inversion, the lowest beds are seen in the deep inlet of Coosmore to 
be thrust over a series of coarse red conglomerates which occupy 
the coast for some distance to the east and west of the inlet. The 
red conglomerates are regarded by the officers of the Geological 
Survey as of Dingle (that is, Lower Devonian) age. But it seems 
to us more probable that they are of Old-Red-Sandstone (that is, 
Upper Devonian) age, both from their resemblance in lithological 
character to the Old-Red-Sandstone conglomerate of Sybil Point, 
and from the fact that they rest unconformably upon the Silurian ; 
while the Dingle Beds, except where their junction with the Silurian 
is faulted, appear to be conformable. 
The beds can best be followed from north to south, the following 
being the succession : at the base, as the beds now lie :—
