One would hardly have been able to identify our small Brickhill 

 Belemnite as the one figured by Roemer and d'Orbigny without 

 the help of other specimens. Ours is a small, simply-tapering 

 fragment of a guard, worn and flattened on its ventral side, and 

 with a very excentric axis of growth- as its most marked character. 

 It is identical with some small Belemnites common in the Hils 

 conglomerate of Goslar, Salzgitter and Schoeppenstadt (Brunswick), 

 where I have collected examples, and in these localities it occurs 

 associated with larger and more typical forms. 



Measurements. Length, 3 J cm.; breadth, side to side, 7 mm.; 

 breadth, back to front, slightly less (6Jmm.). 



Localities. Brickhill (W. M. unique), Farringdon (W. M.), not 



uncommon. 

 N. Europe. Hils conglomerate of Schandelahe, Bredenbeck, 



Achim. 

 8. Europe. Bernese Alps. Wassy, Haute Marne, Neocomian 



(d'Orb.). Romer's type is from the Jurassic 



rocks. 



Belemnites Upwarensis, n. sp. 

 (Plate L, fig. 7, a—d.) 



A most remarkable little Belemnite utterly dissimilar to any 

 other Belemnite that I know in several of its characters, namely in 

 the markings over its whole surface, the structure disclosed by 

 transverse section, and the characters of the alveolar end of the 

 guard. So that although only a single specimen appears to have 

 been found, I have no hesitation in recording it as a new form, 

 under the name Belemnites Upwarensis. 



Description. Guard short and stout, conoidaP, being a little de-
