286 On some Recent and Foss^il Foraminifera, 



has been noticed in any part of the Channel Isles ; but tlie 

 discovery of the above-mentioned fossils in the adjoining sea- 

 bed, occupying an intermediate position, would seem to connect 

 this district with Hampshire and Normandy, and to show the 

 great extent of the Eocene basin or area which formerly ex- 

 isted. Another species obtained by the same dredgings, near 

 Jersey, was Gtrithium vidgatum^ Bruguiere." As this estua- 

 rine species still exists in the Mediterranean region, Mr, Jeffreys 

 thinks that it may have lived in the Jersey area before the 

 coasts were so much submerged as they are now. 



IV. It would be of much interest to know the real place of 

 origin of the fossil Xummulime above mentioned. They are 

 of Eocene age ; but whether washed about at or near any 

 existing patches of Tertiary beds, or drifted some way from 

 their original place of deposit, is not clear. The Discorhinoe^ 

 Planorhulince, and AlveoJince are solid and very much rolled. 

 Some of the more solid NinnmuUnce (chiefly N. Rouaulti) are 

 also much worn. 



Neither a\". JRamondi nor X. Rouaulti belong to the Tertiaries 

 of N.W. Europe. They occur in the Pyrenean and Gascon 

 region, though N. Rouaulti is known to reach as far north as 

 Dax, near Bordeaux, if not, indeed, as far as the Soissonais. 

 The other fossils, however, of the Dredgings under notice, 

 except NuinmuUna Prestioichiana, are found plentifully in the 

 Paris Basin and the Tertiaries of Normandy ; and they abound, 

 together with N. Presticichiana, in the " Bracklesham beds " 

 of Hampshire and the Isle of Wight. This last form was 

 described in the ' Quart. Journ. Geo!. Soc. Lond.' vol. xviii. 

 pp. 93 & 94, as N. plamdata^ var, Prestwichiana^ and possibly 

 may be essentially the same as N. 2jlanulataj var. a. minor, 

 D'A. & H., which occurs at Jette, in Belgium. 



Since we look upon X. Ramondi also as a variety (thick) of 

 X. planulata, and as, according to our view of the nature of 

 Nummulites"^, X. Rouaulti is not far removed from the same 

 subtype, the association of the three Xummulince above men- 

 tioned is not sti'ange in a natural-history point of view, although 

 they have not yet been met Avith elsewhere in company with 

 each other and with the other fossil Foraminifera enumerated 

 above. 



Fossil Nummulites {X. Icevigata ?) have been dredged up in 

 the English Channel by Mr. Godwin-Austen f, and by M. 

 Ernest Vanden Broeck| on the coast of France and Belgium ;
