REMARKS ON SPECIES PREVIOUSLY DESCRIBED. 



CEPHALOPODA. 



In the first part of the ' Crag Mollusca' it was observed that no remains of an animal 

 belonging to this class had been detected in any section of the Upper Tertiaries, or what 

 was there called the periods of the Crag deposits. I am equally unable now to introduce 

 the name of any Cephalopod which maybe presumed to have lived during the time of the 

 Crag or any of the succeeding periods, although I have searched zealously in the hope of 

 obtaining the terminal portion of the bone of the " Cuttle Pish." This bone is in some 

 places left in great numbers on our own shores, and is an organic remain we might 

 expect to find, but as yet I have not seen a vestige of such a fossil in the Upper Tertiaries 

 of the East of England. The mucro of Belosepia, presumed to be similar to that of Sepia, 

 is by no means rare in the sandy beds of Bracklesham or of Grignon.
