 Fossil: Newbournian Crag : Sutton. 



Remarks. — The figure here given was copied from a specimen belonging to the 

 York Museum, which was unfortunately broken while in the artist's hands. It 

 seems to correspond with one descril)ed by Mr. Friele, who remarks its nearest 

 relation was the 0. diapliana of Jeffreys. In form, however, it agrees more closely 

 Avith the 0. ohliqua of Alder, to which at first I was disposed to refer it. Our 

 fossil was obtained from the Red Crag of Sutton.
