I20 DISCOVERY REPORTS 



270. Uvigerina pygmaea, d'Orbigny (F 297). 

 Two stations: WS 33, 349. 



Very rare and weakly developed. 



271. Uvigerina aculeata, d'Orbigny. 



Uvigerina aculeata, d'Orbigny, 1846, FFV, p. 191, pi. xi, figs. 27, 28. 



Uvigerina aculeata, Brady, 1884, FC, p. 578, pi. Ixxv, figs. 1-3. 



Uvigerina aculeata, Cushman, 1910, etc., FNP, 1913, p. 100, pi. xliii, fig. 4. 



Two stations: WS 429, 522. 



Rare at WS 522, but very good specimens. Very rare and weaker at the other 

 station. 



272. Uvigerina raricosta, d'Orbigny (F 299). 

 One station: WS 521. 



Only a single specimen was noted, but it is possible that the species having no very 

 striking characteristics has been overlooked elsewhere among the variations of U. 

 angitlosa. 



273. Uvigerina striata, d'Orbigny (F 300). 



Nine stations: 123; WS 27, 33, 50, 66, 314, 349, 418, 521. 



Extremely rare. Never more than one or two specimens at a station. 



274. Uvigerina angulosa, Williamson (F 301). 



Forty-one stations: 13, 16, 23, 27, 28, 30, 45, 123, 126, 131, 136, 140, 144, 149, 157; WS 25, 27, 28, 

 33. 37. 40, 42, 43. -SO, 51, 52, 66, 113, 154, 314, 348, 349, 351, 357, 373, 418, 426, 428, 521, 522, 523. 



Generally distributed, but by contrast with the Falkland area the species is very rare 

 at the majority of stations. It is, however, common or very common at St. 136, WS 66, 

 314, 357 and 418, and at these stations practically all the variations referred to in the 

 Falkland Report were observed, notably at WS 357. 



275. Uvigerina angulosa var. spinipes, Brady. 



Uvigerina spinipes, Brady, 1879, etc., RRC, 1881, p. 64. 



Uvigerina angulosa, var. spinipes, Brady, 1884, FC, p. 577, pi. Ixxiv, figs. 19, 20. 



Uvigerina angulosa, var. spinipes, Cushman, 1910, etc., FNP, 1913, p. 99, pi. xliii, fig. 3. 



One station: WS 351. 



Extremely rare, represented by a few specimens only. 



Family GLOBIGERINIDAE 

 Genus Globigerina, d'Orbigny, 1826 



Note. At WS 522 at a depth of 2550 m. a few specimens were observed of G. 

 inflata, G. pachyderma and G. dutertrei. What are apparently the parent shells have 

 smaller individuals firmly attached, usually to the last chamber of their tests (see Plate 

 IV, figs. 20-22). They might be regarded merely as monstrosities, but for the fact that
