Miliola ovum, Ehrenberg, 1843, Bericht k. preuss. Wiss. Berlin, 



p. 166; 1854, Mikrogeol, pi. XXIII, fig. 2. 

 Lagena ovum, Brady, 1884, Chall. Rep., p. 454, pi. LVI, fig. 5. 



Extremely rare, one specimen only found in the whole of 

 the material examined. 



(The specimen is a cast, and quite possibly an oval L. Icevis,. 

 with the neck absent.) 



no. Lagena gracillima, (Seguenza.)

 Lagena gracillima, Brady, 1884, Chall. Rep., p. 456, pi. LVI, 



figs. 19-28. 



Very rare, only found in the gatherings from the lowest 

 portion of the beds. 



(The three specimens are all casts and it is doubtful whether 

 they should be referred to this species — the one from Gathering 

 7 is more probably L. apiculata, Reuss, and the two from 

 Gathering 8 probably detached chambers of Nodosaria pvrula, 

 d'Orb.) 



in. Lagena hispida, Reuss. 



Lagena hispida, Reuss, 1858, Zeitschr. deutsch, geol. Ges., vol..

 L. hispida, Brady, 1884, Chall. Rep., p. 459, pi. LVII, figs. 1-4; 



and pi. LIX, figs. 2 and 5. 



Rather rare, but widely distributed. 



(The specimens are nearly all casts and the majority, both 

 in their globular shape and short thick neck, and the coarseness 

 of their external markings are more nearly allied to L. aspera,. 

 Reuss, than to L. hispida, which is usually of oval form.)
