low down as the Inferior Oolite becomes very feeble, and the 

 instances quoted by Mr. Tawney are not altogether, as he tells us, 

 free from doubt, whilst the specific identifications are very uncertain. 

 I do not possess in my own collection a single specimen of Nerincea 

 from the Inferior Oolite of the Sherborne-Yeovil district. 



Continuing the circuit of the Anglo-Parisian basin, Nerincea, 

 according to Deslongchamps,' is entirely absent from the Inferior 

 Oolite of Normandy, including the Ferruginous Oolite, but first 

 makes its appearance in the Great Oolite or " White Stone." Through- 

 out the Inferior Oolite of the rest of France the indications of the 

 genus are but slight, though Nerincea Jurensis, D'Orb. (T. J. vol. ii. 

 p. 80, pi. 251, fig. 1) from the " Calcaire a polypiers" of Salins 

 (Jura) is the representative of the genus on a somewhat high 

 horizon of the Inferior Oolite. Not a single Nerincea is quoted by 

 Brauns from any part of the Brown Jura in N.W. Germany, but 

 Laube gives N. bacillus, D'Orb., as occurring very rarely in the 

 Brown Jura of Balin, though in what part of the Brown Jura he 

 gives no intimation. 



From the above it may be gathered that the very considerable 

 abundance, at the Peak, of a certain form of Nerincea on a low horizon 

 in the Inferior Oolite is exceptional as regards N.W. Europe, and 

 yields additional testimony to the remarkable character of our 

 Yorkshire Dogger.

Bibliography, etc. — In his first edition Phillips referred specimens 

 from the Coralline Oolite, " Impure Limestone " (i.e. Scarborough 

 Limestone and Millepore Eock), and Dogger, all to Turritella cingenda, 

 Sowerby (M. C. p. 499, fig. 3 — 1825), which he fancied to be identical 

 with the fossil figured by him. The type should be at York, but 

 without the aid of this Phillips's figure is sufficiently characteristic 

 of the well-known Nerincea of the Dogger, which, as previously 

 stated, is rather abundant. On the other hand, Sowerby's Turritella 

 cingenda, as we shall see presently, is decidedly rare. Bronn showed 

 that Phillips's figure was that of a Nerincea different from Sowerby's 

 species, whilst both D'Orbigny and Morris endorsed this identifi- 

 cation. Strictly speaking, therefore, we ought to follow the example 

 of those writers and regard it as Bronn's species. 



If any further proof were needed, I might add, from my own 

 knowledge of the Dogger itself, and of all the more important 

 collections therefrom, that the Nerincea figured by Phillips, plate xi. 

 figs. 28, 29, is THE Nerincea of the Dogger. Yet in the 3rd edition 

 of the Geology of Yorkshire, Phillips, as though determined to be
