131. Polymorphina rotundata Bornernann sp. 



Outtulina rotundata Bornemann, 1855, Zeitschr. d. deutsch. geol. Gesell., 



vol. vii. p. 346, pi. xi., pi. xvii. fig. 3. 

 Polymorphina rotundata (Bornemann) Brady, Parker, and Jones, 1870, 



Trans. Linn. Soc. Lond., vol. xxvii. p. 234, pi. xl. figs. 19 a-e and 



woodcuts.

figs. 5-8. 

 Ditto. (Bornemann) Brady, 1887, Synopsis British Becent Foraminifera. 



Fossil. Many and large, and one small recent specimen. The 

 fossils are evidently derived from several different sources. 



132. Polymorphina myristiformis Williamson. 



Polymorphina myristiformis "Williamson, 1858, Becent Foram. Gt. Britain, 



p. 73, pi. vi. figs. 156, 157.

figs. 9, 10. 

 Ditto. (Williamson) Brady, 1887, Synopsis British Becent Foraminifera. 



One good and typical specimen. Eecent. 



133. Polymorphina ornata Karrer. 

 (Plate XVII. fig. 8.) 



Polymorphina ornata Karrer, 1868, Sitz. k. Akad. Wiss., vol. lvii. p. 175, 



pi. iv. fig. 10. 

 Ditto. (Karrer) Brady, Parker, and Jones, 1870, Trans. Linn. Soc. Lond., 



vol. xxvii. p. 242, pi. xli. figs. 34 a, b. 



One fossil specimen, which agrees very well with the figure in 

 Brady, Parker, and Jones's monograph {supra), although the orna- 

 mentation is even more strongly pronounced. It is to all appear- 

 ances derived from the Chalk. The locality of Karrer's specimens 

 is not furnished, but they were presumably Miocene. As pointed 

 out by Brady, Parker, and Jones (supra) this form can hardly be 

 separated from strongly-marked specimens of P. myristiformis 

 (Williamson). 



134. Polymorphina tuberculata d'Orbigny sp. 



Globulina tuberculata d'Orbigny, 1846, For. Foss. Vienne, p. 230, pi. xiii. 



figs. 21, 22. 

 Polymorphina tuberculata (d'Orbigny) Brady, Parker, and Jones, 1870, Trans. 



Linn. Soc. Lond., vol. xxvii. p. 242, pi. xli. fig. 35 a-d. 



Fossil. One specimen only. This form is with difficulty separ- 

 able from the last named species ; probably any considerable 

 number of specimens would present a complete series of transitional 

 types.
