ROTALIIDAE 123 



Genus Pullenia, Parker and Jones, 1862 



286. Pullenia sphaeroides (d'Orbigny) (F 315). 



Six stations: 148; WS 351, 428, 429, 522, 523. 



Always rare. The finest specimens were at WS 522, where great size was attained. 

 More numerous but much smaller at WS 429 and 523. 



287. Pullenia subcarinata (d'Orbigny) (F 316). 



Thirty stations: 20, 27, 30, 123, 126, 136, 140, 144, 148, 149; WS 27, 28, 33, 40, 42, 43, 47, 48, 

 52, 63, 113, 154, 314, 334, 348, 357, 418, 429, 522; MS 68. 



Very variable in its frequency, abundant at some stations, notably WS 27 and 33. 

 Here, as might be expected, there was a great range of variation : specimens inseparable 

 from P. qiiinqueloba were noticed at many stations, but as we have already explained in 

 our Falkland Report we can see no reason for separating Reuss's species from the earlier 

 species of d'Orbigny, the two being linked by endless variations. 



288. Pullenia obliquiloculata, Parker and Jones (F 317). 



Two stations: 30; WS 522. 



A thick-walled variety is very common in the deep water Globigerina oozes of WS 522. 

 This is the only record except a single small specimen from St. 30, which is in Cumber- 

 land Bay (251 m.). Its presence there and the presence of Orbuliua universa at a neigh- 

 bouring station are probably due to the influence of currents. 



Genus Sphaeroidina, d'Orbigny, 1826 



289. Sphaeroidina bulloides, d'Orbigny. 



Sphaeroidina bulloides, d'Orbigny, 1826, TMC, p. 267, no. i, Modele no. 65. 

 Sphaeroidina bulloides, Brady, 1884, FC, p. 620, pi. Ixxxiv, figs. 1-7. 

 Sphaeroidina bulloides, Brady, Parker and Jones, i888, AB, p. 226, pi. xlv, figs. 9-11. 

 Sphaeroidina bulloides, Cushman, 1918, etc., FAO, 1924, p. 36, pi. vii, figs. 1-6. 



One station: WS 522. 



A single small but quite typical specimen at a depth of 2550 m. The position of this 

 station is several hundred miles farther south than the highest record given by Brady, 

 which was in the Southern Ocean, at a position of 46° 46' S, 45° 31' E with a depth of 

 1375 fathoms.

Sub-family SPIRILLININAE 



Genus Spirillina, Ehrenberg, 1841 



290. Spirillina vivipara, Ehrenberg (F 319). 

 One station: 145. 



Two very minute specimens only.
