in magnitude in different places. Near Millstreet it seems to bring 
down the Coal Measures against the Glengariff Grits; but east- 
ward of this the throw is much less; and a little westward it 
is also less, but it increases again as we proceed farther west to 
Killorglin, where there is a patch of Coal Measures, which have 
possibly been brought down against the Glengariff Grits, which 
are there covered by the “OJd Red Sandstone;” still farther west- 
ward it again decreases. 
In conclusion, I should point out that in the Dingle Beds the 
fossils, as yet found, are more or less obscure markings, that may 
belong either to land plants or fucoids. South of the bay at 
Valencia Lighthouse there are tracks suggested by Baily to be 
those of crustacea; they are, however, very similar in aspect 
to the tracks made by the grey gurnet on a sandy bottom. 
The most important fossils, however, are the plants found in 
Glanroe, which are distinctly similar to Sagnaria Veltheimiana 
from Tallow Bridge, co. Waterford, and Knorria Bailyana from 
Kiltorean, both of which localities are in the Upper or Carboni- 
ferous “ Old Red Sandstones.” 
NoTE ADDED IN Press— Vide page 228.—Those who have studied the 
writings of Le Conte and others, on the lowering and upheaval of strata, 
can readily understand that, althoughit is probable a fault orfaults occurred 
at this time in the area of Dingle Bay, yet it or they are not absolutely 
necessary, aS the rocks to the northward may have been crumpled and 
raised up, so as to come under the influence of denudation without a 
break having taken place.
