Station 3. 



One fossil, not typical. 



ROTALIA, Lamarck. 



597. Rotalia beccarii (Linne). 



Nautilus beccarii, Linne, 1767, SN. (ed. xii), p. 1,162, no. 276. 



Rotalia „ Heron-Allen and Earland, 1914, etc., FKA. 1915, p. 717. 



Stations 2, 4-6, 25, 27, 47 (+ K. I.). 



The extraordinary rarity of this dominant species is astonishing. At most 

 Stations it is represented by one or two feeble specimens, the best at Station 5. 



598. Rotalia perlucida, Heron-Allen and Earland. 



Rotalia beccarii (pars), Balkwill and Wriglit, 1885, DIS. p. 351.

 FKA. 1915, p. 718 ; 1916. FWS. p. 277. 



Stations 6. 8. 36. 



A few typical examples. The description by Renss of his species Rotaliua 

 nitida seems to indicate that his form had something in common wath ours 

 (R. 1844, KWB. p. 214) but he gives no figure, and the figures published in his 

 later paper (R. 1845-6, VBK. p. 35, pi. viii, fig. 52 ; pi. xii, figs. 8, 20) are quite 

 unidentifiable. 



599. Rotalia orbicularis (d"Orbigny). 



Gjjroidiria orbicularis, d'Orbigny, 1826, TMC. p. 278, no. 1, Modrle no. 13. 

 Rotalia „ Heron-Allen and Earland, 1914. etc.. FKA. 1915, p. 718. 



Stations 6, 10, 11 (+ R. d. J., D.). 



Many excellent examples at each Station. Brady's figure (pi. cvii, fig. 5) is 

 very misleading, it has nothing in common with d'Orbigny's Model and is clearly 

 a pauperate form of R. beccarii, very near R. perlucida. 



600. Rotalia soldanii, d'Orbigny. 



Rotalia {Gyroidina) soldanii, d'Orbigny, 1826, TMC. p. 278, no. 5, ModMe no. 36. 

 „ soldanii, Heron-Allen and Earland. 1014, etc., FKA. 1915. p. 719. 



Stations 2, 3, 5-9, 12, 16-19, 22, 27, 29, 32 (+ T. d. F., R. d. J.). 



Universally distributed, and frequent as far as Station 16. From thence it 

 becomes smaller and rarer, and at the most southerly Stations the examples 

 become very small and pauperate. Its maxmium development in size at Station
