Apkil 26, 1871. 



Robert EusseU, Esq., of the Geological Survey of England and 

 "Wales, was elected a Fellow of the Society. 



The following communications were read : — 



1. On a New Species of Coeal /rom the Eed Crag- of "Waldringfield. 

 By P. Martin Duncan, M.B,, F.R.S., F.G.S., Prof. Geol. King's 

 Coll, Lend., &c. 



The solitary specimen of a compound Madreporarian which forms 

 the subject of this communication, was found by Mr. Alfred Bell at 

 Waldringfield, and was sent to me for description. The coral is 

 interesting, because it belongs to a reef-forming type which has 

 lasted from the Eocene to the present day, and which, doubtless, 

 some day or other, wiU prove to be much more ancient. 



The specimen had been considerably rolled and worn before its 

 deposition amongst the other materials constituting the Bed Crag, 

 and it must therefore be regarded as a remanie fossU. It becomes, 

 therefore, rather important that the geological age of the form should 

 be determined ; but as its mineralization affords no assistance in 

 this inquiry, any satisfactory results must depend upon the correct 

 appreciation of its palaeontology. 



Genus Solenastrjea, Milne-Edwards & Jules Haime, 1848. 



Solenastrcea Prestwichi, sp. nov. 

 The corallum is short, and the corallites are crowded. 

 The upper surface is very irregular, and the corallites differ in 

 size.
