"310 DR. J. W. GREGORY ON THE PAEE ONTOLOGY [Aug. 1895, 



which they furnish goes it is strongly in favour of the Oligoeene 

 age of the deposits. The fossils are as follows : — 



Entaliopsis ? aff. rudis (Gabb). 

 Cuphus aff. incrassatus, Gabb. 

 Cardita aff. scabricostata, Guppy. 

 Ostrea, sp. 

 Lampusia ( = Triton), sp. 



The best-preserved fossil has been kindly identified by Mr. G. F. 

 Harris as a very close ally of Surcula transversaria (Lam.). This 

 is a common Oligoeene species ; it occurs, for example, at Brocken- 

 hurst, and ranges down to the Middle Eocene. Mr. Harris states 

 that the general aspect of the fossils resembles that of the Brocken- 

 hurst Beds and their equivalents in the Paris Basin. 



Mr. B. B. Newton has kindly determined three mollusca from the 

 Scotland Beds collected by Mr. Jukes-Browne. They are allied to 



Clavilithes longcevus (Sol.). 

 Neritina aperta, J. de C. Sow. 

 Potamides funatus, G. Sow. 



Mr. B. B. Newton says that these ' are probably of Lower Oligo- 

 eene age (Headon Beds).'

Discussion. 



The President alluded to the interest which the Fellows of the 

 Society had for many years past taken in the geology of the West 

 Indian area. He cited the papers published in the Geological 

 Society's Journal by old West Indian workers such as De la Beche, 

 R. Lechmere Guppy, Sawkins, Wall, Lucas Barrett, while our past 

 President, Prof. P. Martin Duncan, had done much in the study of 

 the corals ; then, too, we had papers by Harrison, Jukes-Browne, 

 Agassiz, and more than twenty other workers, who had laboured 

 in this field of enquiry. Dr. Gregory had added new points of 

 interest to the geology of this area, and in his paper had dealt
