the Upper Jura of the Aargau ; and from the whole Swiss Jurassic 



formation he has determined about sixty species, including the 



Textularidfe. They belong to the genera : — 

 Fsammosphmra, Meophax. Wehbina. 



Astrorhiza. Haplophragmium, Thurammina. 



Mhahclammina, Haplostiche. Textularia {Plecanium) . 



Marsipella. Flacopsilina. Bigenerina. 



Hi/perammina, Trochammina. Valvulina. 



Iiituola, Eormosina. 



A few species are'identical with Carboniferous or Permian forms ; 

 but most of them most nearly approach recent deep-sea species and 

 varieties, although similar forms do not occur in the younger for- 

 mations. The species described in the present paper are from the 

 zone of Amm. transversarius, and are as follows : — -Psammosphcera 

 fusca, Schultze, Hyperainmina vagans, Brady, Beophax multilocularis, 

 sp.n., B. helvetica, Hausl., B. scorpiiirus, Montf., Placopsilina arenacea, 

 d'Orb., Thurammina papillata, Brady, and T. hemisphmrica, sp.n. 

 Most of the recent genei'a of Astrorhizidte and Lituolidee would seem 

 to have been represented by species identical with, or nearly allied 

 to, those now existing, at the time Of deposition of the beds with 

 Ammonites transversarius.

SUBMERGED FOEESTS ON THE SUFFOLK COAST. 



Sir, — In 1874-5, whilst the river Orwell was being deepened, 

 and a new channel cut, a bed of peat was discovered. This v/as 

 carefully examined and worked by myself and Mr. Thos. Miller, 

 C.E,, the Ipswich Dock Engineer, and the published results appear 

 in the Report of the British Association (Bristol) Meeting, 1875. 

 This peat-bed was as much as nine feet thick, full of the trunks of 

 trees, and from it we obtained several grinders of the Mammoth. 

 It was traced down towards Harwich for a distance of six miles, 

 and, at the time, I pointed out that this ancient forest could only 

 have grown when the land stood relatively so much higher than the 

 present sea-level that the bed of the German Ocean must have been 

 marshy land, probably characterized by similar extensive shallow 

 lakes to those which are so abundant in the flat, eastern parts of 

 Norfolk, where they are known as " Broads." 



Fishermen off the Norfolk and Suffolk coasts frequently bring up 

 lumps of peat in their trawl nets, and that the bed of the German 

 Ocean off these parts must be occupied by extensive deposits of this 

 kind is shown by the unfailing supplies. Bones and teeth of Ele- 

 phant, Ox, Deer, etc., are strewn over the area, and are often dredged 

 up. Those who are acquainted with the magnificent collection of 

 these remains made by Mr. Owles, of Great Yarmouth/ nearly all of 

 which were dredged up by Yarmouth fishermen, will be prepared 

 to substantiate the statement that the floor of the German Ocean is 

 occupied by extensive post-glacial deposits, with their characteristic 



^ Now preserved in tlie Britisli Museum of Natural History.
