 Globigerina sp. (?) rubra, Brady, 1884, FC, p. 603, pi. Ixxxii, figs. 8, 9. 

 Globigerina rubra, Heron-Allen and Earland, 1913, FNS, p. 131, pi. x, figs. 13-15. 



Nineteen stations : 228, 235, 236; WS 71, 73, 79, 83, 86, 88, 90, 92, 109, 221, 245, 248, 408, 409, 

 432. 433- 



Often very abundant, especially in the muddier gatherings. Particularly well- 

 developed and plentiful at WS 71, 83, 88, 92 and 409. 



313. Globigerina digitata, Brady. 



Globigerina digitata, Brady, 1879, RRC, p. 72 ; 1884, FC, p. 599, pi. Ixxx, figs. 6-10; pi. Ixxxii, 



figs. 6-7. 



Globigerina digitata, Cushman, 1918, etc., FAO, 1924, p. 11, pi. ii, figs. 9-1 1. 



One station: WS 108. 



A single, young, but unquestionable individual of this species, from WS 108. This 

 station is well to the north of the Falkland Islands and close to the American coast, 

 but a long way south of any Atlantic record known to us. The species is much commoner 

 in the Pacific than in the Atlantic Ocean, but never of very frequent occurrence. 



Genus Orbulina, d'Orbigny, 1826 



314. Orbulina universa, d'Orbigny. 



Orbulina universa, d'Orbigny, 1839, FC, p. 3, pi. i, fig. i. 



Orbulina universa, d'Orbigny, 1839, FIC, p. 123, pi. i, fig. i. 



Orbulina universa, Brady, 1884, FC, p. 608, pi. Ixxviii ; pi. Ixxxi, figs. 8-26; pi. Ixxxii, figs. 1-3. 



Nine stations: 388; WS 88, 91, 92, 93, 108, 210, 221, 248. 



The species is extraordinarily rare, never more than two or three specimens at a 

 station, usually a single one. With the exception of WS 88, where a single thin-walled 

 specimen with internal globigerine chambers was found, all the specimens are thick- 

 walled, bottom-living individuals, mostly smaller than the average size. 



Genus PuUenia, Parker and Jones, 1862 



315. Pullenia sphaeroides (d'Orbigny). 



Nonionina sphaeroides, d'Orbigny, 1826, TMC, p. 293, no. i, Modele no. 43. 

 Pullenia sphaeroides, Carpenter, Parker and Jones, 1S62, IF, p. 184, pi. xii, figs. 11, 12. 

 Pullenia sphaeroides, Brady, Parker and Jones, 1888, AB, p. 266, pi. xliii, figs. 21, 24. 

 Pullenia sphaeroides, Cushman, 1910, etc., FNP, 1914, p. 20, pi. xi, fig. 2. 



Eight stations: 388; WS 86, 88, 90, 92, 408, 409, 433. 



The distribution of this species is curiously restricted. At three stations WS 86, 88 and 

 92 (which are on the Burdwood Bank, or on the Continental Shelf close to the American 

 Coast), the species is represented by single small individuals (two at 388), but at the re- 

 maining stations, which are beyond the Continental Shelf, the species is frequent, large
