BRITISH BELEMNITES. 



Dun dry. The Bath Oolite series also yielded him specimens corresponding or allied to 

 B. sulcatus of Miller, from Shcrburn, Birliphill, Earmington, Yanworth, Northleach, Colne 

 Aliens, in Gloucestershire ; and Barrington, in Oxfordshire. The Marlstone of Clipston, 

 in Northamptonshire, furnished specimens probably of B. paxilloms. 



Erom the Lias of Boughton and Ashley, in Northamptonshire, joints probably of the 

 phragmocone of B. elongatus, Sow. ; and from the Upper Lias (Alum Shale) of Whitby 

 several specimens, probably of B. vulgaris, Young and Bird. 



One remarkable locality, Silverton, Devonshire, is quoted for several specimens of a 

 conic Belemnite, with " a seam or sulcus running down one side of this body for the whole 

 length of it." This obviously describes a canaliculate species of the Inferior Oolite ; but 

 Silverton is situated in the Trias. Perhaps we ought to read Silverston, in Northampton- 

 shire. On the whole, it may be concluded that the following species were handled by Dr. 

 Woodward :

In 17C)4 Mr. Joshua Piatt, a patient and not unsuccessful explorer of the fossils of 

 Stonesfield, near Oxford, communicated to the Royal Society observations on the 

 structure of Belemnites, 1 which contain the sound opinion that the Belemnite was a shell 

 formed, as the hard parts of mollusca are, by deposition from a secreting surface. 



In the elegant Avork of Mr. Parkinson, 1804, Belemnites appear among the "organic 

 remains of a former world," and the terms employed by Woodward retain their place. 

 The " conic" Belemnite, the " cylindrical" Belemnite, and the "fusiform" Belemnite of 

 Stonesfield, the large, nearly round fossil of the Oxford Clay, and the mucronate form of 

 the Chalk, are represented, but not critically distinguished. 



In 18.23 the Geological Society of London received from Mr. J. S. Miller, a native of 



1 'Phil. Trans.,' liv, p. 38. Mr. Piatt was the "discoverer" of the Stonesfield mammals, though, 

 perhaps, he may not have known the full value of the lower jaw of Amphitherium Br oderipi i (Owen), 

 which formed part of the collection furnished by him to an ancestor of my late friend, the Rev. C. Sykes, 

 of Rooss, who, at my request, gave the specimen to the Yorkshire Phil. Society. (See Owen, ' Brit. 

 Mammal.,' p. 58.)
