On Foraminifera, &c. By G. D. Sherlorn & F. CJiapnan. 487 



Vaginulina sp, plate XI. fig. 25. — A small, compressed, and 

 deformed (?) Nodosarian of doubtful relationship. 



MARaiNULiNA d'Orbigny [1826]. 



Marginulina aitenuata Neugeboren, plate XI. fig. 27. Neuge- 

 boren, Verb. Mitth. Siebenbiirgen Yer. Nat., Jahrg. ii. (1851) p. 121, 

 plate iv. figs. 3-6. — The name M. attenuata may reasonably be made 

 to include the whole of the unornamented elongated Marginulinse 

 figured by Neugeboren on his plate iv. Indeed, in his later paper 

 (ibid., Jahrg. xi. 1860, p. 55) he has referred three of his former 

 species {M. Oi'hignyana, M. Reussiana, and M. irregularis) to M. 

 attenuata, thus showing that he did not then agree with the specific 

 value of gradational varieties. Our specimen is the only one found. 

 Not previously noted from the London Clay. 



Marginulina costata (Batsch), plate XI. fig. 28. Nautilus 

 [Orthoceras) costatus, Batsch, Sechs Kupfertafeln Conch. Seesandes, 

 1791, p. 2, plate i. figs. 1 a-g. — Only this specimen found. New to 

 the London Clay. 



PuLLENiA Parker and Jones [1862]. 



Pullenia quinqueloba (Keuss), plate XI. fig. 29. Nonionina 

 quinqueloha Reuss, Zeitschr. Deutsch. Geol. Ges., iii. (1851) p. 47, 

 plate V. figs 31 a, h. — Only one specimen of this shghtly compressed 

 form has been found; it shows, however, all the characteristics of 

 Keuss's variety. New to the London Clay. 



DiscoRBiNA Parker and Jones [1862]. 



Discorhina rugosa (d'Orbigny), plate XI. fig. 33. Bosalina 

 rugosa d'Orbigny, Foram. Amer. Merid., 1839, p. 42, plate ii. figs. 

 12-14. — One specimen, which has lost the final chamber, occurs in 

 the Piccadilly washings. New to the London Clay. 



Anomalina d'Orbigny [1826]. 



Anomalina grosserugosa (G-iimbel), plate XI. fig. 34. Trunca- 

 hilina grosserugosa Griimbel, Abh. k.-bay. Ak. Wiss., x. (1868) p. 660, 

 plate ii. fig. 104 a, h ; Anomalina sp. Sherborn and Chapman, Journ. 

 E. Micros. Soc, ser. 2, vi. (1886) p. 757, fig. 156.— Having found 

 more specimens of this form, we are able to assign it definitely to 

 Giimbel's "species," according to the suggestion expressed in our 

 former paper.

Pulvinulina elegans (d'Orbigny), plate XI. figs. 30-32. Rotalia 

 {Turhimdina) elegans d'Orbigny, Ann. Sci. Nat., vii. (1826) p. 276,
