﻿TERTIARY BRACHIOPODA.

Jura' of Bopfingen, Wiirtemberg, although it has been stated that some specimens 

 referable to that species have been met with in the Drift of Norfolk. 



Erratic blocks containing T. ovoides have been picked up in the Drift of several parts 

 of Norfolk and Suffolk, especially at Gisleham, near Lowestoft, and Thorpe in Suffolk ; 

 Stow Bardolph, Downham ; Roslyn Pit, Ely ? Feltwell, Norfolk, &c. 



It has also been stated by Mr. R. Lankester that at least some of the derived, rolled, 

 and water-worn internal casts (PL I, figs. 15, 16) that occur in the Lower Greensand at 

 Upware are likewise referable to T ovoides ; and it is possible that such may be the case, 

 although some of the specimens are comparatively broader and shorter than in the typical 

 forms of Sowerby's species, as found in the Drift of Suffolk. 



As to the geological age of T. ovoides, considerable uncertainty must still prevail, 

 although Mr. Lankester has informed us, in his valuable paper already quoted, that 

 Mr. Seeley has found a rock in situ beneath the bed of the Cam, between Ely and 

 Upware, and which would agree in stratigraphical position with the very highest of the 

 Oolites. Its relation, however, to this rock requires further confirmation. 



Besides T. ovoides, a large and very convex Terebratula (PL I, fig. 17) was found by 

 Mr. C. B. Rose in the Drift of North Pickenham ; and I possess a block of sandstone 

 from the Drift of the same county, containing L. ovalis, as well as a species of Discina. 

 Several very much worn and rolled specimens of Jurassic and Cretaceous Rhynclionellce 

 have also been obtained, by Mr. Walker, from among the derived fossils occurring in the 

 Lower Greensand at Upware and Potton, which require to be carefully studied. 



SUPPLEMENT TO THE BRITISH TERTIARY BRACHIOPODA. 



Athough twenty-three years have elapsed since the publication of my ' Monograph of 

 British Tertiary Brachiopoda ' not a single new species has been discovered, and, indeed, 

 of several of those I have described in 1852 no specimen has been again collected. 



With the exception of Lingula tenuis, Terebratulina striatula, and Terebratula grandis, 

 all the other forms remain extremely rare. 



In France, Belgium, Germany, and Switzerland, Tertiary Brachiopoda are likewise 

 specifically few in number ; and, if we except Terebratula grandis and three or four others, 

 the species of that period are scarcely obtainable. In Italy, on the contrary, Tertiary
