Nine stations: 53° 00' S, 34° 22' W; WS 199, 334, 336, 353, 365, 429, 521, 522. 



Confined to the deep-water stations, the shallowest depth from which the species was 

 recorded being 2549 m. at WS429. Here the specimens were few and small, except for 

 a fragment which must have belonged to a specimen far larger than any perfect one 

 found. At WS 353 a large fragmentary specimen was obtained at a depth of 4041 m. 

 The best specimens were from WS 199 and from a sounding of Diatom ooze taken in 

 53° 00' S, 34° 22' W (2472 m.). All the specimens except one were uniform in ap- 

 pearance, very smooth and neatly finished with fine grey mud, no coarse material being 

 used. The exception occurred at WS 522, where of two specimens found, one was 

 normal, the other very large and constructed of nearly black sand and cement. Young 

 individuals, which have not grown beyond the triserial stage, occur at most stations. 

 At WS 336 there were many of these, but no adult shells. Megalospheric specimens 

 predominate everywhere. 



Sub-family BULIMININAE 



Genus Bulimina, d'Orbigny, 1826 



166. Bulimina fusiformis, Williamson (F 124). 

 Four stations: 15, 129, 151 ; WS 18. 



Common at St. 15, very rare elsewhere. 



167. Bulimina elegans, d'Orbigny (F 127). 

 Five stations: 16, 136, 157; WS 37, 426. 



Rare everywhere but well developed. Best and most numerous at St. 157 and WS 37. 



168. Bulimina marginata, d'Orbigny (F 129). 

 Five stations: 20, 29, 149; WS 41, 47. 



Only a single specimen at each station except at St. 149, where several were obtained. 

 They are uniformly small and pauperate, except the specimen from St. 29, which is 

 normal.
