Sub-family LOFTUSINAE 

 Genus Cyclammina, Brady, 1876 



211. Cyclammina cancellata, Brady (F 114) (SG 147). 



Thirteen stations: 362, 383-5; WS 403, 471, 495, 502, 505, 506, 507 A, 552, 555. 



Frequent and large, both megalospheric and microspheric, at St. 383 in the Drake 

 Strait, depth 3744 ni. : very fine microspheric specimens were also frequent at St. 

 WS 502 in the Bellingshausen Sea, depth 4224 m. With these exceptions the species is 

 rare, though widely distributed, seldom more than one or two specimens at a station. 

 With the exception of St. WS 502 the specimens from the Bellingshausen Sea stations 

 (WS 495, 505, 506 and 507 a) are small, and far from typical as compared with the rest. 



212. Cyclammina orbicularis, Brady (SG 148). 

 Eight stations: 369, 382; WS 384, 403, 495, 502, 505, 555. 



Good specimens everywhere, but never more than one or two, except at St. 369 in 

 the South Sandwich Islands, depth 1767 m., and at WS 495 in the BeUingshausen Sea, 

 depth 2582 m., where the species is frequent. The stations are scattered over the entire 

 area, depths ranging between 1500 and 4224 m. 



213. Cyclammina pusilla, Brady.

 Cyclamjnina pusilla, Goes, 1894, ASF, p. 32, pi. vi, figs. 242-4. 



Cyclammina pusilla, Cushman, 1910, etc., FNP, 1910, p. iii, fig. 172; 1918, etc., FAO, 1920, 

 p. 56, pi. xi, figs. 4-6. 



Nine stations: 383; WS 495, 502, 503, 505, 506, 507 A, 507B, 517. 



Common at Sts. WS 502 and 503, both of which are in depths of over 4000 m. ; 

 frequent at all the other stations except WS 506 and 517. Depths range between 572 m. 

 at St. WS 507A and 4224 m. at St. WS 502. Except St. 383, which is in the Drake 

 Strait, all the stations are in the Bellingshausen Sea ; its absence from the Weddell Sea 

 and Scotia Sea stations is rather remarkable, as the species has a world wide distribu- 

 tion. Pearcey recorded it from Scotia stations in both the Scotia and Weddell Seas, but 

 nowhere common (Pearcey, 1914, SNA, p. 1009). 



214. Cyclammina bradyi, Cushman. 



Trochammina trullissata {pars), Brady, 1884, FC, p. 342, pi. xl, fig. 13 (only). 



Cyclammina bradyi, Cushman, 1910, etc., FNP, 1910, p. 113, fig. 174; 1918, etc., FAO, 1920, 



p. 57, pi. xi, fig. 3. 



Eight stations: 373, 384; WS 502, 506, 517, 552, 553, 555. 



Rarely more than a single specimen at each station, and mostly microspheric; but 

 megalospheric specimens were found at St. WS 517, and also in company with micro- 

 spheric at St. WS 553. The stations are all in deep water between 2515 and 5029 m. in 

 the Weddell, Scotia and Bellingshausen Seas, except St. WS 506 which is off the conti- 

 nental ice in the Bellingshausen Sea, depth 584 m. The specimens sometimes have sand 

 grains included in the cement, an unusual feature in this species.
