ON LIFE-ZONES IN THE BRITISH CARBONIFEROUS ROCK, 171 
Life-zones in the British Carboniferous Rocks.—Interim Report of the 
Committee, consisting of Mr. J. KE. Marr (Chairman), Dr. WHEEL- 
ton Hinp (Secretary), Dr. F. A. Batuer, Mr. G. C. Crick, 
Dr. A. H. Foorp, Mr. H. Fox, Professor E. J. Garwoop, Dr. G. J. 
Hinpe, Professor P. F. Kenpati, Mr. R. Kinston, Mr. G. W. 
LaMpPLuGH, Professor G. A. Lesour, Mr. B. N. Peacnu, Mr. A. 
SrraHan, Dr. A. Vauauan, and Dr. H. Woopwarp. (Drawn up 
by the Secretary.) 
Work has been carried on by Mr. J. T. Stobbs in the Holywell district of 
North Wales and in North Staffordshire. Mr. H. Bolton is engaged in 
investigating the fauna of a marine band lately discovered by him in the 
lower coal measures of the Bristol coalfield—a most important and inter- 
esting discovery. The marine band is being mined and brought to bank 
at the expense of the Committee, and a detailed paper will be published at 
an early date. 
Owing to the early date at which this report is required, it must of 
necessity be incomplete. Arrangements have been made on the one hand 
with Mr. Stobbs and Mr. E. P. Turner, and on the other with Mr. D. 
Tait, to undertake work which cannot be done except in the summer, and 
naturally the result of this work cannot be included; and it is also impos- 
sible to state whether there remains over any balance of the grant. The 
Committee wish to continue the work, and ask for the balance of the grant, 
if any, to be left in their hands, and that a further grant of 10/. be made. 
Money has been expended in having sections of corals cut for examination. 
The exact recognition of the species and genera of any coral occurring 
at a definite horizon has been shown by Dr. Vaughan to be of the highest 
importance. 
My own work during the year has been, first, in the Hodder Valley 
with Mr. Stobbs, the results of which will appear later ; second, in the 
West of Ireland, where I have demonstrated a typical Pendleside fauna 
succeeding the Carboniferous Limestone. The results have been published 
in the ‘Proceedings of the Royal Irish Academy,’ with figures of the 
majority of fossils found in the equivalents of the Pendleside series and 
Millstone Grits in County Clare and County Limerick. The main details 
of the paper are summed up as follows :— 
1. The Pendleside series of the Midlands is well represented in County 
Clare. 
2. These beds in County Clare are about 80 feet thick, and they lie 
conformably on the upper beds of the Carboniferous Limestone, which 
seems to have the same top all over the county, and in County Limerick. 
3. The fossils are identical with those found at Chokier, in Belgium, 
and in the Pendleside series of England. 
4. The fossils which characterise the lowest beds of the Pendleside 
series—viz. Posidonomya Becheri and Prolecanites compressus—have not 
yet been found in County Clare. 
5, That the series of grits and flagstones which overlie the Upper 
Limestone Shales are, as stated by the Geological Survey, the homotaxial 
equivalents of the Millstone Grits, and are largely marine in origin, several
