226 SUPPLEMENT TO THE BRITISH 



flies), and beyond the eastern slope of Shotover. Mr. James Parker, of Oxford, 

 informs me — " There are two large quarries still open at Wheatley, the stone there 

 being practically a free stone, and used largely for building. In the Bursar's Rolls of 

 Merton College, when they were building a new kitchen a.d. 1278, we read 'Idem 

 comput. iiij.s. liberatos Nicholai Pret. pro viii. Magnis francis lapidibus, qui vocantur 

 sules (i. e. Sills or fr. Seuils), emptis apud Watele.' But the stone does not stand the 

 town atmosphere." 



Lingula Brodiei is quite distinct from another elongated Lingula, of about the same 

 size (Sup., PI. XXIX, fig. 22), likewise found by the Rev. P. B. Brodie in the 

 Concretionary Junction Bed at Ringstead Bay, near Weymouth, between the Coral 

 Rag and Kimmeridge Clay, and alluded to at p. 43 of the ' Proceedings of the War- 

 wickshire Naturalists' and Archaeological Field Club,' 1874. 1 In pp. 76 and 77 of this 

 Supplement, I confused two Lingula, which are situated in widely separated localities, 

 and perhaps distinct geological horizons. Mr. Brodie's specimen is too incomplete to 

 admit of a positive identification.

An upper or unattached valve only of this species has been found by Mr. Innes 



1 " On Thursday some of the members drove to Ringstead Bay, commencing with the coast section of 

 Coral Rag on the West, and thence to Ringstead, where a fine section of the clay, full of fossils, is exposed, 

 capped by the Purbeck, and further on to the East is succeeded by the Lower Chalk and Greensand. A 

 peculiar band called Kimmeridge Grit was noticed between the Coral Rag on the West and Ringstead ; it is 

 said to contain fossils of the Coral Rag and Kimmeridge Clay, the latter, however, appearing to 

 predominate ; and the Rev. P. Brodie found a Thecosmilia, of which several specimens were obtained, 

 which differs from common species (T. annularis) of the Coral Rag, and does not seem to have been 

 noticed here before. The following section and fossils were determined : 



" 1. Clay, with layers of Ostrea deltoidea, Rhynchonella inconstans, and Gryphcea virgula. 



"2. Stone sand with Corals {Thecosmilia, sp. ?). Lingula very elongated (not ovalis), Serpula 

 intestinalis, Trigonia clavellata, Lima pectiniformis, Pholadomya angustata, Phasianella striata, Lima, 

 Thracia, Gervillia, and Cucullcea. 



"3. Clay full of Ostrea deltoidea, Gryphcea virgula, Serpula intestinalis, Rhynchonella inconstans. 

 Dip to the East. 



" No. 2 is said in Damon's • Guide to Geology of Weymouth ' to be the concretionary junction bed, a 

 few inches thick between Kimmeridge Clay and Coral Rag ; in this the Corals occur, and it is overlain by a 

 stratum of clay charged with the characteristic fossils of the Kimmeridge Clay ; and No. 3 below contains 

 similar fossils. The intervening stony band must belong to the Kimmeridge Clay, and as far as could be 

 observed all the other associated organisms are well-known Kimmeridge Clay species, and, if so, this is 

 the first time any Coral has been found in it." 



2 This species has been referred to by the Rev. F. Smithe, F.G.S., in his admirable memoir on the 

 ' Middle Lias of North Gloucestershire,' in which paper the Ammonites sjrinatus zone is particularly- 

 described. Mr. Smithe states that Brachiopoda of the Tretenterate division are scarcely to be expected in 

 the Spinatus sands.
