BRITISH BELEMNITES. 



were clearly distinguished, and the several parts of this somewhat complicated shell placed 

 in comparison with the corresponding parts of Belemnoteuthis. In 1S49, further details 

 from other examples were communicated by the same indefatigable naturalist to the 

 Geological Society, showing the two remarkable processes already alluded to. The author 

 expressly declares that he had never found in specimens of the numerous Belemnites 

 which he had examined any trace of the ink-bag or its dark contents. 



The volume for 1S50 of the ' Memoirs of the Palasontographical Society' contains an ac- 

 count of the Cephalopoda of the Stonesfield Slate by Prof. Morris and Mr. Lycett. Two 

 species are described and figured, viz., B.fusiformis, Park., and B. Bessinus D'Orb., which 

 is regarded by Oppel as a synonym of B. sulcatus, Miller, and B. canaliculatus, Schl. 



In the volume for 1853 of the same Society the Belemnitida? of the Upper Cretaceous 

 system are described and figured by Mr. Sharpe, five species, which will be found with the 

 same names in the Catalogue of Prof. Morris. 



Prof. Morris presents in his ' Catalogue of British Fossils,' edition 2nd, 1854, the 

 following thirty-one species :
