74 DISCOVERY REPORTS 



referred to in the South Georgia report. At St. WS 384 a single rather doubtful 

 specimen was found, with a produced neck but no basal aperture. 



This species is probably very widely distributed in cold waters, as I have found 

 specimens in a dredging from Hilte Fjord, near Bergen, Norway, 260 m. (F.C. ' Gold- 

 seeker', Haul 141). 



Genus Hyperammina, Brady, 1878 



Note. At several stations, notably Sts. 180, 195, WS 394, 474, 476, fragmentary 

 specimens which cannot be identified with any certainty are not uncommon. The 

 majority are probably referable to Hyperammina, but other genera such as Rhabdam- 

 mina, Marsipella and jfaadella may also be involved. They have been disregarded in the 

 preparation of this report. 

 115A. Hyperammina friabilis, Brady (F 71). 



Three stations: 363 ; WS 497, 517. 



Found only in the Weddell Sea and Bellingshausen Sea, and always very rare. The 

 best and typical specimens at St. WS 517 in 2770 m. At the other stations, 329-534 m., 

 the specimens are smaller and not quite typical. 



116. Hyperammina elongata, Brady (F 72) (SG 85). 



Twenty stations: 180, 181, 197, 198, 363, 373, 382; WS 201, 203, 377, 383, 385, 395, 471, 498, 

 507 A, 509, 515, 517, 555. 



Usually rare or very rare, so far as perfect specimens or identifiable fragments are 

 concerned. The most typical examples were found at St. WS 471 (3762 m.), where the 

 species was very rare. A rough variety constructed of coarse sand grains is frequent at 

 St. 181, and represents the species at most of the other shallow- water stations, but it was 

 also found in 2770 m. at St. WS 517. 



117. Hyperammina laevigata, J. Wright (F 73) (SG 86). 

 Five stations: 169, 180, 360, 366; WS 468. 



Frequent at St. 169, very rare elsewhere. The majority of specimens are grey, and 

 devoid of that excess of cement which gives the typical form such a polished orange- 

 coloured test. 



118. Hyperammina clavigera, Heron-Allen and Earland (F 74). 

 Three stations : 175, 177, 196. 



Very rare at all stations. A few excellent specimens in perfect condition were found 

 at St. 175 in 200 m. In the specimens from the other stations the proloculus is missing, 

 but I think there can be no doubt as to their identification. All the stations are in the 

 Bransfield Strait, and the presence there of a species first recorded from the Falklands 

 area, and absent from South Georgia, is clear evidence of the mixture of warm- and cold- 

 water species to be found in the Bransfield Strait, due no doubt to an influx of Pacific 

 water. 



119. Hyperammina novae-zealandiae, Heron-Allen and Earland (F 75) (SG 87). 

 One station: WS 515.
