1 2 HALKYARD, Fossil Foraminifera of the Blue Marl 



Frequent through the whole series of gatherings but in 

 the lower half of the beds is represented principally by calcite 

 casts. 



(Very fine and typical specimens from Gathering 3. Less 

 marked and smaller from elsewhere. From several localities 

 the specimens are represented only by casts and identification 

 is often only a matter of opinion, as the casts might refer to 

 any Miliolid of similar structure.) 



17. Miliolina ferussacii (d'Orbigny). 



Quinqueloculina ferussacii, d'Orbigny, 1826, Ann. Sci. Nat. 

 VII, p. 301, No. 18. 



Not rare and approaching M. contorta (d'Orb.) in form. 



(Except from Gathering 1, the specimens are nearly all 

 casts, and the specific features are therefore unidentifiable. 

 From Gathering 1 the individuals are in our opinion nearer to 

 M. contorta than M. ferussacii.) 



18. Miliolina agglutinans (d'Orbigny). 



Quinqueloculina agglutinans, d'Orbigny, 1839, De la Sagra, 

 Flist. Phisiq. etc., Cuba, " Foraminiferes," p. 195, pi. XII, 

 figs. 11-13- 



Miliolina agglutinans, Brady, 1884, Chall. Rep., p. 180, pi. 

 VIII, figs. 6 and 7. 



Rare and typical. 



19. Miliolina bicornis (Walker & Jacob). 



Scrpula bicornis, Walker & Jacob, 1798, Adam's Essays Micr., 



p. 633, pi. XIV, fig. 2. 

 Miliolina bicornis, Brady, 1884, Chall. Rep., p. 171, pi. VI, 

 figs. 9, 11, 12. 



Very small and very rare. 



(The few specimens from G. 3, represent several distinct 

 types, the true M . bicornis being absent. They are very small 

 and worn but so far as can be identified with certainty include 

 M. brongniartii (d'Orb.), M. boueana (d'Orb.), and M. striata 

 (d'Orb.). )
