132. Anomalina grosserugosa (Giimbel). 



Truncatulina grosserugosa, Giimbel, Abhandl. bayer. Akad. 

 Wissensch. 2te CI. vol. x. (1868) p. 660, pi. ii. fig. 104 a, o. 



Anomalina grosserugosa, Brady, ' Challenger ' Eep. vol. ix. (1884) 

 p. 673, pi. xciv. figs. 4, 5. 



This is a fairly deep-water species, and it also occurs fossil in 

 beds of Tertiary age. 



One specimen from the Pebble-beds, Littleton. 



Pulvinulina, Parker & Jones. 



133. Pulvinulina PTJNCTULATA (d'Orbigny). 



Rotalina punctulata, d'Orbigny, Ann. Sci. Nat. vol. vii. (1826) 

 p. 273, no. 25 : Modele no. 12. 



Pulvinulina punctulata, Brady, ' Challenger ' Rep. vol. ix. (1884) 

 p. 685, pi. civ. fig. 17 a-c. 



A small and not very typical example of this species was found in 

 the Pebble-beds, Littleton. 



134. Pulvinulina Schreibersii (d'Orbigny). 



Rotalina Schreibersii, d'Orbigny, 'Poram. Foss. Vienne,' 1846, 

 p. 154, pi. viii. figs. 4-6. 



Pulvinulina Schreibersii, Brady, ' Challenger ' Rep. vol. ix. (1884) 

 p. 697, pi. cxv. fig. 1 a-c. 



This species appears to be restricted to shallow water. As a 

 fossil it had hitherto made its first appearance in Miocene strata. 



One specimen from the Pebble-beds, Littleton. 



135. Pulvinulina Karsteni (Reuss). 



Rotalia Karsteni, Reuss, Zeitschr. deutsch. geol. Gesellsch. vol. vii. 

 (1855) p. 273, pi. ix. fig. 6. 



Pulvinulina Karsteni, Brady, 'Challenger' Rep. vol. ix. (1884) 

 p. 698, pi. cv. figs. 8, 9. 



P. Karsteni has been recorded from beds of Upper Cretaceous 

 age, and also from later Tertiary formations. As a recent form it 

 appears to be restricted to shallow water, and it is usually found in 

 high latitudes. 



Four specimens from the Pebble-beds, Littleton. 



136. Pulvinulina elegans (d'Orbigny). 



Rotalina (Turbinulind) elegans, d'Orbigny, Ann. Sci. Nat. vol. vii. 

 (1826) p. 276, no. 54. 



Pulvinulina elegans, Brady, ' Challenger ' Rep. vol. ix. (1884) 

 p. 699, pi. cv. figs. 4-6. 



P. elegans seems to make its earliest appearance in beds of 

 Liassic age, and it is found in most important formations of later 

 date. The species is closely allied to P. Partschiana (d'Orbigny), 

 but the former represents the shallow-water type, and it is this 

 form which is present in the Bargate series of foraminifera. 



One specimen from the Pebble-beds, Littleton.
