SUPPLEMENT TO THE BRITISH 



4. Terebratulina caput-serpentis, Linne. Dav., Tert. Mon., PI. I, figs. 14, 15. 



Terebratulina caput-serpentis, S. Wood. Sup. to the Crag Mollusca, p. 168, pi. xi, 



fig. 3, 1874. 



I have nothing new to add. It occurs but very rarely in the 1 Crag noir ' or ' Systeme 

 Diestien' of Belgium. In England it is found in the Coralline Crag at Sutton, where 

 it is stated by Mr. S. Wood to be very rare; and indeed very small and young 

 individuals only have been obtained. 



5. Terebratulina striatula, Sow. Dav., Tert. Mon., PI. I, fig. 16. 



Mr. Wetherell informs me that T. striatula has been found in the following localities : 

 — Finchley, near Highgate ; in the well at the Lower Heath, Hampstead ; near Cuffell, 

 Nunsham, &c. Prof. Morris, in his 4 Catalogue/ second edition, p. 160, 1854, gives 

 Highgate as a locality ; but Mr. Wetherell considers that this species belongs to a 

 much lower zone than that of Highgate in the London Clay. In a paper " Observations 

 on some of the Eossils of the London Clay, and in particular those organic remains 

 which have been recently discovered in the Tunnel for the London and Birmingham 

 Railway at Primrose Hill," 'Phil. Mag.' ser. 3rd, vol. ix, p. 462, 1836, Mr. Wetherell 

 gives the names of several fossils which he considered to be characteristic of three 

 zones, viz. Upper (as at Highgate), Middle, and Lower; and T. striatula he names as 

 belonging to the last. Specimens have been found likewise by Mr. Meyer in a mass 

 of London Clay thrown up from a considerable depth during the excavations of the 

 London and Chatham Railway. It is not rare in the Island of Sheppey, but the 

 specimens found there are not often in a good state of preservation. T. striatula 

 occurs in the 4 Etage Landenien superieur,' = 4 Woolwich and Reading Series ' of 

 Prestwich. 



6. Terebratula bisinuata, Lamarck. Dav., Tert. Mon., PI. I, fig. 17 (?) ; and 



Appendix, PI. A, fig. 2. 



This species continues to be exceedingly rare. I know of but two well-authenticated 

 British examples — the one in the collection of Mr. Cunningham, and the other in that of 

 Mr. J. E. Walker, of York ; both of these were found in the Eocene Clay of Barton 

 Cliff in Hampshire. I am very uncertain whether the specimen figured in PI. I really 

 belongs to the Lamarckian species : I much fear that it does not.
