The discovery of these fossils is interesting, on account of the scarcity of 
organic remains in the Silurian rocks of this part of Ireland, and their palse- 
ontolo^ical evidence fixes the age of the beds in which they were found as 
belonging to the Lower Llandovery period. 
Although the rocks containing these fossils are obviously of Silurian age, 
the author felt called upon to mention incidentally, upon the authority of the 
discoverer, J. Darby, Esq., that an old Cambrian fossil, Oldhamia radiata, had 
been found upon the hill, and the specimen itself was laid before the section. 
A strong probability certainly exists that it might have been found in situ 
here, but unfortunately, as its locality could not now be pointed out, the fact 
remained to be decided by future discovery.

RECENT ENCROACHMENTS OF THE SEA ON THE SHORES OF 
TORBAY. 
By W. Pengellt, F.G.S. 
If, as some masters of our science tell us, and as I venture to believe, tbe 
Ideological changes which have passed over our world during the unmeasured 
ages of the past, were due to the direct and indirect operation of existing 
causes, acting, perhaps, with intensities not greatly dissimilar to those they 
now display, it can scarcely be out of order to call attention, from time to time, 
to changes taking place under bur immediate observation, even though they 
may be slight in themselves, and, regarded as isolated facts, of little worth or 
importance. 
Requesting the Section to keep this apologetic preface before them, I will 
now proceed to narrate a few facts respecting the recent encroachments of the 
sea on the shores of Torbay.
