5. k ' On some new Cretaceous Comatulce." By P. Herbert 

 Carpenter, Esq., M.A. Communicated by Prof. P. Martin Duncan, 

 M.B., F.R.S., F.G.S. 



In this paper the author described five new species of Antedon 

 from British Cretaceous deposits, two of them in the possession of 

 the Eev. P. B. Brodie, the rest in the collection of the British 

 Museum. The species are : — Antedon perforata and A. Lundgreni, 

 from the Upper Chalk, Margate ; A. striata, from the Upper Chalk, 

 Dover ; A. laticirra, from the Chalk of Wylye, Wiltshire ; and 

 A. incurva, from the Upper Greensand, Blackdown. The author 

 further gave a tabular key to the known English Cretaceous species 

 of Antedon, and in conclusion referred to certain peculiarities in the 

 structure of these fossils, apparently subservient to the circulation of 

 water in their interior. 



6. " A Review of the Family Vincularidee, recent and fossil, for 

 the purpose of Classification." By G. R. Vine, Esq. Communi- 

 cated by Prof. P. M. Duncan, M.B., F.R.S., F.G.S. 



The author examined in detail the insufficient description of the 

 genus Vincularia by its founder Defrance, and the manner in which 

 it has been employed by subsequent authors. He concluded that 

 the different forms, ranging from the Carboniferous to the present 

 day, which have been included in the genus, present no such features 

 in common as would justify the retention of the generic or family 

 name. 



7- "On the Zones of Marine Fossils in the Calciferous Sandstone 

 Series of Fife." By James W. Kirkby, Esq. Communicated by 

 Prof. T. Rupert Jones, F.R.S., F.G.S. 



In this paper the author described the marine beds that he has 

 met with in the Calciferous Sandstones of the east of Fife, and 

 traced the sequence of over 4000 feet of beds, probably all belonging 

 to the " Cement-stone group." In the section from the west 

 of Pittenweem to Anstruther he recognized eighteen zones, which he 

 characterized by their contained fossils ; in the section at Randerstone 

 he distinguished eleven limestone beds ; and he compared and, as far 

 as possible, correlated the two series of deposits. Full lists of fossils 

 were given ; and the author further specially discussed the characters 

 and distribution of the more important species.
