Vol. 58.] | THE FOSSILIFEROUS SILURIAN BEDS OF KERRY. 227 
we are acquainted is contained in a paper by Thomas Weaver,' 
entitled ‘On the Geological Relations of the South of Ireland.’ In 
this paper, which was read before the Geological Society of London 
on June 4th, 1830, the author mentions a number of fossils from 
the Ferriter’s-Cove beds, and refers to the existence of a strong 
resemblance between many of the casts of fossils found there and 
similar casts occurring at Tortworth in Gloucestershire. 
In a paper published in 1835, C. W. Hamilton compares some 
features of the geology of the Dingle promontory with that of 
North Wales, and notes the occurrence of Silurian fossils in the 
Ferriter’s-Cove beds. 
Sir Richard Griffith, writing in 1839,’ also refers to the occurrence 
of Silurian fossils in the Dingle promontory, and notes the fact that 
the Old Red Sandstone is there unconformable to the clay-slate beds 
beneath it. 
in 1857, J. B. Jukes & G. V. du Noyer* brought a very im- 
portant account of the district before the British Association, 
an abstract of the paper being published in the report of the 
Transactions of the Sections. . The authors note the presence of 
contemporaneous traps as well as ashes among the Silurian beds. 
They are the first to THCUET ES the peculiar structure of the district, 
which they describe as ‘an inverted S-like contortion or anticlinal 
and synclinal curve, and they lay stress on the strong unconformity 
between the Dingle Series and the Old Red Sandstone. 
In the same volume is an abstract of a paper by J. W. Salter, 
in which it is stated that the 
‘Silnrian and Lower Devonian, taken in a rough sense, lie in a rude, faulted, 
and broken synclinal, the lowest beds being respectively at Sybil’s Head on the 
north, and at the Bull’s Head promontory east of Dingle on the south.’ 
Salter remarks also upon the persistent ‘ fucoid-beds’ at the base of 
the Ludlow Series, and’ on certain noteworthy points in the distri- 
bution of the Wenlock and Ludlow fossils: for example, that Chonetes 
lata (Ch. striatella, Dalm.), a characteristic Ludlow fossil in Britain, 
is most abundant in the Lower Wenlock Beds of the Clogher-Head 
district. 
The only full account of the district is that by Jukes & 
Du Noyer, contained in the Explanation of Sheets 160, 161, 171, 
& 172 of the Geological Survey Map of Ireland. This account, 
which was published in 1863, proved of very great value to us. 
The authors remark on the extreme difficulty in understanding 
the structure of the district, and regard the classification of the 
beds which they propose as merely provisional. Aithough in their 
previous paper, to which reference has already been made, they 
alluded to the occurrence of contemporaneous ‘traps’ as well as 
ashes among the Silurian beds, here mention is made of ashes only :
