I.—Gerotoaicat Soctrry oF Lonpon. 
November 8, 1916.—Dr. Alfred Harker, F.R.S., President, 
: in the Chair. 
The President referred to the loss which the Society had 
sustained during the recess by the decease of its Treasurer, 
Mr. Bedford McNeill, A.R.S.M., M.Inst.M.M., A.M.Inst.C.E. | 
He spoke of Mr. McNeill’s eminence in his profession, and of 
the services that he had rendered to the Society as a Member 
of Council for many years and as Treasurer since 1912. The 
President mentioned that the Society was well represented 
at the funeral, and added that he felt sure that the Fellows 
would associate themselves with the resolution of condolence 
and sympathy which the Council had addressed to Mrs. McNeill. 
The following communication was read :— 
‘‘ dulina rotiformis, gen. et sp. uov., Phillipsastrea hennahi 
(Lonsdale), and the genus Orionastrea.’’ By Stanley Smith, B.A., 
D:Se., 2 .G:s: 
The primary object of the present communication is a description 
of a new and interesting coral genus of colonial habit, Aula, 
obtained from the highest limestone that can be associated with the 
Lower Carboniferous—the Fell Top Limestone of Northumberland 
and its equivalent horizon in Teesdale, the Botany Beds. 
Since this form has been confounded with another Carboniferous 
species well known under the name of ‘ Phillipsastrea radiata 
(S. Woodward)’, it has been found advisable, in fact necessary, to 
extend the original scope of the paper so as to include a revision 
of the genus Phillipsastrea and a description of ‘ Ph. radiata’ and its 
allies, which I have grouped together under a new generic name, 
Orionastrea. Several type-specimens, including that of Phillips- 
astrea hennahi (the genotype of Phillipsastrea), are described and 
figured. 
The new genus from the Fell Top Limestone is a very distinctive 
form, on account of the remarkable annular wall developed within 
the theca, and may prove of considerable value as a zonal index.
