Hill, in part an Astarte obliqiia bed — precisel)' similar to that at Half- 

 way House and Burton Bradstock ; at Hadspen, mainly a massively 

 bedded brown building-stone (locally called * Hadspen Stone '), full of 

 fossils. Similar rock is seen at Shotwell and Woolston ; but south 

 of Blackford the Garantiana beds coalesce, as it were, with the 

 superincumbent representative of the Doulting Stone, etc., and, while 

 the lower part eventually passes into the Sherborne Building-stone, 

 the upper portion (together with the equivalents of higher beds) 

 becomes rubbly, associated with clayey matter, and passes into the 

 Rubbly Limestone beds of the Sherborne district. 



Above the Garantiana beds come, near the Mendips, the massive 

 Doulting Stone, Anabacia limestones, and Rubbly Beds. The Atiabacia 

 limestones soon lose their distinctive lithic characters ; but the 

 Doulting Stone spreads over the whole of the Oolitic tract between 

 Doulting, Bruton, and Cole, and is exposed in numerous quarries. 



South of Blackford, as already remarked, the equivalent of the 

 Hadspen Stone [garantiancB) is not easy to separate from the equivalent 

 of the Doulting Stone, etc. In the southern portion of the district, 

 the lower portion of the equivalent of the Hadspen Stone passes into 

 the Sherborne Building-stone, and the top portion, plus higher beds, 

 into the Rubbly Limestone beds such as those that are so well dis- 

 played in numerous quarries in the eastern portion of the Sherborne 

 district. 



Samples of the soft layers and of the marly matter from the 

 interstices of the more rubbly beds have been examined by Mr. Charles 

 Upton for micro-organisms ; but they have proved singularly deficient 

 in such organisms. 



2. "Some Inferior Oolite Pectens." By E. Talbot Paris, B.Sc, 

 F.C.S., and Linsdall Richardson, P.R.S.E., F.G.S. 



During the course of one of the present authors' (L. R.) field work 

 in connexion with the unravelling of the detailed stratigraphy of the 

 Inferior Oolite of the district between Stonesfield, in Oxfordshire, and 

 Burton Bradstock, in Dorset — which is now completed — a large 

 number of specimens of Lamellibranchs were found. Some of the 

 Gervillm and Pernce have already been dealt with (Proc. Cotteswold 

 Nat. F.C., vol. xvii, pp. 233-5 and pi. xi, and pp. 237-54 and 

 pis. xxviii-xxix, 1911). The present paper deals with the species 

 of Pectinidse that have been found during the investigations above 

 mentioned. 



Descriptions and illustrations are given of one new species of 

 Camptonectes, of two new varieties of Chlamys articulata (auctt.), and 

 of two new species of Velopecten.

1. " On a Raised Beach on the Southern Coast of Jersey. " By 

 Andrew Dunlop, M.D., F.G.S. 



Last June Mr. E. F. Guiton drew attention to a raised beach 

 recently exposed on the southern coast of the island. It is on the
