76 REPORT—1858. 
fern, named by Prof, Edward Forbes Cyclopteris Hibernica*, and obtained in such 
great profusion from the Upper Devonian or base of the Carboniferous system at Kil- 
torkan Hill, County Kilkenny, as having received additional interest from the discovery 
of several specimens exhibiting it in various stages of fructification, and illustrating 
other parts of its structure, forming part of a large collection recently made by the 
Geological Survey from that locality. 
A diagram illustrating these particulars was exhibited and explained, including, 
first, what was considered to be the base of the stem or rhizoma, having a rounded 
expansion, apparently separating into scales, which continued upwards, fragments of 
leaflets being attached to the stem at different intervals. The venation of a leaflet, 
from one of the principal pinnules, presented longitudinally arranged striz which 
were occasionally forked. 
One of the fertile pinnules of a specimen showed the spores were aggregated int 
clusters or sori, and that the indusium or protecting cover had been but little broken 
up. A fertile pinnule from another specimen, however, appeared to be in a more 
advanced stage, losing in a great measure the aggregated character of the sori, and 
showing the protecting cases (which were granulated) to be much disturbed, 
Other specimens in the collection were alluded to; one of which, with a length 
of 16 inches, had twelve pinnules on each side of the rachis in full fructification, 
without any appearance of leaflets, the spore-cases being scattered in all directions ; 
another, of the same length, had about twenty pinnules on each side, the lower ones 
being in full fructification, which decreased gradually towards the upper portion of 
the frond, the leaflets taking its place. 
Mr. Baily, having visited the locality, found the ferns to be most numerously distri- 
buted through the beds which were composed of a fine-grained compact greenish 
yellow sandstone, readily splitting into thin layers, some specimens presenting an 
appearance of irregular venation and distortion as if from softening or maceration in 
water: associated with them were many other plants and specimens of a large fresh- 
water bivalve, Anodonta Jukesit (Forbes), having both valves united. About 3 feet 
from the surface, in a much coarser and more irregular sandstone not splitting into 
lamina, numerous fish remains were collected, believed to be the osseous plates of 
Coccosteus (like C. decipiens), and with them asingle tooth of a Sauroid fish, probably 
Dendrodus, being the second specimen of that kind obtained from this locality. 
The beds were found to dip at a very slight angle, about four or five degrees 
to the S.W., having angular joints, in the neighbourhood of which they were much 
broken up. 
The section exposed was stated to be as follows :— 
No. 1. A superficial deposit from 18 inches to 2 feet, with broken fragments con- 
taining the same plants as in the beds beneath. 
No. 2, Fine-grained greenish shale with Cyclopteris and other plants, 1 foot, 
No. 8, Coarser sandy bed not splitting into layers, with Coccostews, and few plants, 
1 foot. 
No. 4, Fine-grained sandy shale, with Cyclopteris and other plants, splitting into 
layers, the lower beds being coarse, and the Cyclopteris large but not well-preserved. 
On two new species of Crustacea (Bellinurus, Konig) from the Coal Measures 
in Queen's County, Ireland ; and some Remarks on forms allied to them. 
By W.H. Baty, £.G.S., and of the Geological Survey of Ireland. 
The peculiar Coal-measure Crustacea, described by Mr. Baily, were first discovered 
by Mr. George Henry Kinahan of the Geological Survey of Ireland, at the Bilboa 
Colliery, Queen’s Co., in debris obtained from the three-foot bed of shale imme~ 
diately over the coal, associated with a few plants and numerous small bivalve shells 
(Myacites) allied to Unio, together with others of the Mytiloid form (Myalina) ; the 
deposits in which they occur, like those of Coalbrook Dale, from which the allied 
forms were first obtained, being of freshwater or estuarine origin, 
Mr, Baily alluded to a paper, previously read before the Geological Society of 
.. * Exhibited by the late Professor Forbes at the Meeting of the British Association at Bel- 
fast in 1852. ; He
