OP THE UPPER CRETACEOUS IN WEST SUPPOLK AND NORPOLR. 579 



Stoke the stone does not yield so many fossils, but then its 

 diminished thickness must be taken into account. Its fauna in 

 Norfolk does not offer any special peculiarities, and no doubt more 

 prolonged search would greatly increase the number of fossils, and 

 prove the assemblage to be the same as in Cambridgeshire.

Fish-scales 



The assemblage above recorded is such as might be found in the 

 same subdivision further south, with the exception of Belemnitella 

 ■plena. The occurrence of this species in the grey chalk of West 

 Row near Mildenhall is a noteworthy fact, for it is its first 

 recorded occurrence at such a distance below the Marls which form 

 the zone of Bel. plena. The species from the Totternhoe Stone 

 which has elsewhere been called Bel. plena is not that form, but the 

 Bel. lanceolata of Sowerby (non Schlotheim). 



The original example of Peltastes Bunburyi, Forbes, was obtained 

 near Mildenhall by Sir E. H. Bunbury, and may therefore have 

 come from the West Row pit. 



The marls of the zone of Belemnitella plena in Norfolk have as 

 yet yielded but two species, Terebratula semiglobosa and Rhyn- 



West Eow.
