March 25th, 1903.—Prof. Charles Lapworth, LL.D., F.R.S., 
President, in the Chair. 
The following communications were read :— 
1. ‘On a New Species of Solenopsis from the Pendleside Series 
of Hodder Place, Stonyhurst (Lancashire).’ By Wheelton Hind, 
MED ECs EGss. 
This specimen of a perfect left valve was found by the Rev. Charles 
Hildreth, in shales belonging to the Pendleside Series, which have 
yielded the following fossils :—Phillipsia Van der Grachtvi, Ph. Pollen, 
Prolecanites compressus, Glyptoceras spirale, Gil. reticulatum, Gl. platy- 
lobium, Orthoceras annulosolineatum, Posidonomya Becheri, Solen- 
opsis major, and a few brachiopods. 
2. ‘ Note on some Dictyonema-like Organisms from the Pendleside 
Series of Pendle Hill and Poolvash.’ By Wheelton Hind, M.D., 
F.R.C.S., F.G.8. 
Mr. D. Tate discovered a specimen, in the shales and limestones 
in the Angram Brook, which had some resemblance to a Dictyonema ; 
and he afterwards found another similar specimen, on or about the 
same horizon, at Poolvash. These are referred to distinct species, and 
doubtfully assigned to the genus Dictyonema. A piece of shale from 
the Bishopton Beds in Glamorganshire has somewhat similar, but 
less distinctly reticulate markings. 
May 13th, 1903.—Edwin Tulley Newton, Esq., F.R.S., ° 
Vice-President, in the Chair. 
The following communication was read :— 
‘ Description of a Species of Heterastrea from the Lower Rheetic 
of Gloucestershire.’ By Robert F. Tomes, Esq., F.G.S. 
The specimen described was obtained by Mr. L. Richardson from 
Lower Rheetic Beds at Deerhurst (Gloucestershire). It occurred 
a little way above the bone-bed; it is specifically new and gene- 
rically new to the Rhetic, and it displays Jurassic relationships. 
Tt differs from the several Liassic species in the small size of the 
corallum and of its calices. Remarks on some other Madreporaria 
from the Rhetic and from the basement of the Lower Lias are 
appended. It has always been the Author’s opinion that the 
Sutton Stone containing Rhetic Madreporaria should be classed 
as Rheetic; indeed he believes that it is really Upper Rhetic; and 
in view of the very close affinity of its organisms with those of the 
Lower Jurassic, and bearing in mind the great importance of the 
ammonite-zones as a means of classification of the Liassic deposits, 
he asks whether the zone of Ammonites planorbis should not be 
taken as the bottom of the Lias.
