SYSTEMATIC ACCOUNT 39 



Genus Cystammina, Neumayr, 1889 



97. Cystammina pauciloculata (Brady) (SG 144) (A 208). 

 One station: 447. 



A single specimen. 



Pearcey (as Atnmochilostoma {Trochammina) pauciloculata): 447 "a few specimens". 



Subfamily LOFTUSINAE 

 Genus Cyclammina, Brady, 1876 



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

 Four stations: 280, 303, 418, 421. 



Frequent at St. 421, both megalospheric and microspheric ; single specimens only at 

 the other stations. Nearly all are more or less abraded, and it is possible that the speci- 

 mens may have been carried by ice from shallower water, as the species is not usually 

 found in great depths. Some of the specimens at St. 421 are coated with a thin black 

 layer of manganese, evidence that the shells have been dead for a long time. 



Pearcey: 420, 447 "rarely". 



99. Cyclammina contorta, Pearcey (Plate I, figs. 29-31). 



Cyclammina contorta, Pearcey, 1914, SNA, p. 1009, pi. ii, figs. 5-7. 

 One station: 438. 



Three specimens in more or less perfect condition, which I refer tentatively to 

 Pearcey's species, though in the absence of his types identification is uncertain. 



The specimens agree better with Pearcey's figure than with his description, in which 

 he states that the last two convolutions completely envelop the others. The figures on 

 the other hand show only one external convolution, and in this respect agree with my 

 specimens. 



I doubt whether C. contorta is anything more than a local form of C. cancellata. The 

 colour scheme to which he draws attention is not a reliable diagnostic feature; the 

 "suture lines, very dark, almost black "occur in one of my specimens, but not in the 

 others, and may be due to a coating of manganese, as in some of my specimens of 

 C. cancellata from St. 421. 



Pearcey: 417, 420 "not abundant". 



100. Cyclammina orbicularis, Brady (SG 148) (A 212) (Plate I, figs. 27, 28). 

 Five stations: 313, 406, 417, 418, 432A. 



Common in the soundings from Sts. 406, 418 and in the trawl washings from St. 417, 

 all of which are near the coast of Coats Land. Rare in the soundings from Sts. 313 

 and 43 2 A which are far out in the Weddell Sea. 



It is inexplicable how Pearcey can have overlooked this large species. 



loi. Cyclammina pusilla, Brady (A 213) (Plate I, figs. 25, 26). 

 Fourteen stations: 280, 282, 286, 290, 295, 300, 301, 303, 312, 313, 406, 416, 417, 418. 

 Common in the soundings at Sts. 282, 290, 295, 301, 312; frequent in soundings at
