ROTALIIDAE 127 



309. Truncatulina praecincta (Karrer) (Plate IV, figs. 28-30). 



Rotcilia praecincta, Karrer, i868, MFKB, p. 189, pi. v, fig. 7. 



Tnaicatiilina praecincta, Brady, 1884, FC, p. 667, pi. xcv, figs. 1-3. 



Trmicatulina praecincta, Cushman, 1910, etc., FNP, 1915, p. 39, fig. 42 in text, pi. xxvi, fig. 2. 



Two stations: 123, 144. 



Many excellent specimens, especially at St. 144. They agree even better with Karrer's 

 original figure of the fossil form than with recent figures of the species. Its presence 

 in South Georgia is very anomalous, as recent records appear to be confined to tropical 

 seas. 



310. Truncatulina haidingerii (d'Orbigny) (F 365). 



Four stations: WS 28, 33, 521, 522. 



Very rare, never more than one or two at each station, the best at WS 522. The speci- 

 mens agree very well with Brady's figure but are probably not the same organism as the 

 fossil recorded by d'Orbigny from the Vienna Basin, if his figure of the latter is reliable. 



311. Truncatulina robertsoniana, Brady. 



Truncatulina robertsoniana, Brady, 1879, etc., RRC, 1881, p. 65 ; 1884, FC, p. 664, pi. xcv, fig. 4. 

 Cibicides robertsoniana, Cushman, 1918, etc., FAO, 1931, p. 121, pi. xxiii, fig. 6. 



One station : WS 27. 



A single small specimen referred with some doubt to this species. While presenting 

 most of the typical features, the sutures on the dorsal side are more oblique than usual. 



312. Truncatulina tumidula, Brady (F 366). 

 Six stations: WS 33, 428, 429, 521, 522, 523. 



Very common at WS 429 at a depth of 2549 m. ; rare to very rare at the other stations. 



313. Truncatulina bradyana (Cushman) (F 367). 

 Two stations: WS 33, 521. 



All the specimens are very poor except at WS 521. It is very rare at both stations. 



Genus Anomalina, d'Orbigny, 1826 



314. Anomalina vermiculata (d'Orbigny) (F 369). 

 Three stations: 30, 149; WS 27. 



Extremely rare. A nearly fully developed specimen was found at St. 149. At WS 27 

 two well-developed specimens in the intermediate stage occurred and a similar one at 

 St. 30. The rarity of the species as compared with its abundance in the Falkland area is 

 no doubt due to the difference of temperature.
