above described under the designation of Coomhola grits, as un¬ 
doubtedly Carboniferous; and, therefore, on the Avicula Damnoni- 
ensis, the Cucullgese, and the other shells, as Carboniferous species. 
The Knorria and some other plants occur in these beds, as well as 
in those below them, namely, the variegated series of the upper part 
of the Old Red Sandstone, to which, so far as is yet known, the 
Cyclopteris Hibernioa and the Anodon are confined. 
The Society met on the 12th of December, 1855, on which occasion 
the following Paper was read. 
ON THE OCCURRENCE OF PERMIAN MAGNESIAN LIMESTONE AT TULLYCON- 
NEL, NEAR ARTREA, IN THE COUNTY OF TYRONE. BY PROFESSOR 
WILLIAM KING, QUEEN’S COLLEGE, GALWAY. 
At the Belfast Meeting of the British Association, held in 1852, 
I read a short paper “ On the Permian Fossils of Cultra,” which 
was hastily got up from an inspection of some specimens in the 
collection of my friend, Mr. James M‘ Adam, of Belfast, who kindly 
placed them at my disposal for description. 
Cultra is situated near Hollywood, on the south shore of Bel¬ 
fast Lough. 
At the time my paper was read, I was simply aware that the 
Cultra beds yielding the “ Permian fossils” had been described 
by Mr. James Bryce as of the same age as the magnesian limestones 
of the north of England; and that Dr. Griffith, on the contrary, 
considered them to belong to the Carboniferous System; but I was 
not acquainted with any of their published papers on the subject. 
Several months afterwards, on reading over Mr. Bryce’s pamph¬ 
let, prepared for the occasion of the Belfast Meeting of the British 
Association, and entitled, “ Geological Notices on the Environs of 
Belfast, the East Coast of Antrim, and the Giant’s Causeway” 
(1852), I saw for the first time an account of the “Permian Strata 
of Cultra.”* About the same period I also became acquainted with 
* Op. cit., pp. 20-22.—Since writing the above I have received from Mr. 
M‘Adam, part iii., vol. i., of the Journal of the Geological Society of Dublin, 1837, 
containing Mr. Bryce’s first paper, entitled, “On the Magnesian Limestone and 
Associated Beds which occur at Hollywood, in the County of Down,” and read 
April 8, 1835.
