466 Notices of Memoirs— 
successful manner shown the possibility of the task for the considera- 
tion of which the Committee was initially appointed. 
The Committee in submitting this final report desire to place on 
record their appreciation of the energy and enthusiasm of their 
secretary, Dr. Wheelton Hind. 
Report on the work done.—Mr. H. Bolton, in an admirable paper, 
brought before the Geological Society the work he had done on the 
fauna of a marine horizon at the base of the Bristol Coalfield, a work 
towards which a portion of the grant was applied some two years ago. 
His paper will doubtless appear in the Society’s Quarterly Journal, 
and it is unnecessary to say more here. 
Mr. Tait, collector of the Geological Survey of Scotland, has been 
examining the Millstone Grit succession east of Lancaster this 
Summer; and Mr. Watson, of Owens College, has been working in 
the upper part of the valley of the Nidd. It has not been possible to 
examine their collections in time for this report. 
The Secretary was fortunate enough to secure a fine collection of 
plants obtained in an abortive attempt to find coal at Thirshfield, near 
Grassington, in the valley of the Wharf. The exact place of the 
sinking is lat. 54° 3’, long. 2° 2’, and the shales are stated to be those 
which occur below a bed of Millstone Grit. } 
Mr. Kidston has kindly examined the specimens for him, and the 
following list is the result :— 
Sphenopteris elegans, Bet. Sphenophyllum tenerrimum, Ett., sp. 
Calymmatotheca Stangeri, Stur. Lepidodendron sp. 
Rhodia Moraviea, Ktt., sp. Lepidostrobus sp. 
Sphenopteris sp. Small Lycopodiaceous bract. 
Calamites Ostraviensis, Stur. Rhabdocarpus (?) sp. 
Calamites sp. 
Mr. Kidston states, with regard to the horizon: ‘‘I have not the 
slightest doubt that the bed these specimens come from is on the 
horizon of the Upper Limestone group of the Carboniferous Limestone 
Series of Scotland.’”? At any rate, we know that the Lower Limestone 
group of Scotland has a fauna which indicates the Upper Dzbuno- 
phyllum zone. 
VIII.—Tue Faunat Succession 1n THE CaRBONIFEROUS LIMESTONE OF 
tHE Souru-West or ENG Lanp.' 
HE work has progressed steadily, but less rapidly than was antici- 
pated owing to the necessity which has arisen of investigating 
the validity of certain genera and the correct application of specific 
names. 
1.—The Avonian Sequence in Gower. 
The zoning of the Avonian sequence of the Gower Peninsula, 
undertaken in conjunction with Mr. E. E. L. Dixon in the Summer 
of 1905, is now completed, and the results will be presented to the 
Geological Society early next session. 
1 Report of the Committee, consisting of Professor J. W. Gregory (Chairman), 
Dr. A. Vaughan (Secretary), Dr. Wheelton Hind, and Professor W. W. Watts, 
appointed to enable Dr. A. Vaughan to continue his Researches thereon. (Drawn 
up by the Secretary.) Read before Section C (Geology), British Association, 
Leicester, 1907.
