3. On Upper Eocene Fossils from the Isle of Wight. 



By Prof. E. Sandberger. 



[From a Letter to W. J. Hamilton, Esq., F.R.S., For. Sec. G. S., &c.] 



As you wish me to give you my opinion respecting these Tertiary 

 beds of the Isle of Wight, I will do it as fully as I can at present *. 

 I consider the upper formations of Hempstead to be the exact 

 equivalent of those at Weinheim, Jeurres, and Bergh (Bupelien in- 

 ferieur, Dumont). I had already arrived at this opinion, on receiving 

 from Saemann, in Paris, Valuta Forhesi, Edw., which Mr. Edwards 

 himself considers as identical with V. Bathieri, together with some 

 other fossils which have hitherto only been found in this horizon. 

 The collection now sent adds Cerithium plicatum, with varieties, 

 which Mr. Edwards calls C. suhcostellatum, Eorb., and C. inor- 

 natum, Morr. ; also 0. elegans, Desh. ((7. variabile, in the collection, 

 and G. Austenii belong to the same species), C. Lamarckii, Brongn. 

 ( = (7. Sedgwickii, Morr.), also Ostrea adlata, S. Wood ( = 0. cgathula, 

 JjSiioii.,juv.), Lucina Thierensi, Heb., Corhula suhpisum, D'Orb., Pano- 

 poea minor ^ Forb. (= P. Heberti, Bosq.,jiW.), Ostrea callifera^ Lam., 

 0.longirostris,IjSim..,TeUinaN^gstii,'Desh.. (Tellina, sp.indeterm. in the 

 collection), Lithodomus delicatulus, Desh. (Modiola, sp. indeterm. in 

 the collection), hitherto only known from Merigny, Waldbockelheim, 



* I had forwarded to Prof. Sandberger a collection of Upper Eocene fossils 

 from the Isle of Wight, made for him by Mr. F. Edwards, F.Gr.S.— W. J. H,
