SYSTEMATIC ACCOUNT 31 



50. Reophax pilulifer, Brady (F 82A) (SG 97) (A 137). 

 One station: 417. 



Only a single small specimen. The rarity of this species compared with its frequency 

 in Discovery material (A 137) is no doubt due to the greater depth of the Scotia 

 soundings. 



Pearcey: 291, 301, 313, 420 "not common". 



51. Reophax fusiformis (Williamson) (F 83) (SG 99) (A 138). 

 One station : 290. 



A single small specimen. 



52. Reophax dentaliniformis, Brady (F 84) (SG loi) (A 140). 

 One station: 313. 



Very small and rare. The greater depth is probably responsible for the scarcity of a 

 species so abundant in Discovery material (A 140). 

 Pearcey: 313, 447 "rare but typical". 



53. Reophax spiculifer, Brady (SG 100) (A 141). 

 Three stations: 312, 406, 418. 



Occasional fragments at each station. 



54. Reophax longiscatiformis, Chapman (A 142). 

 Two stations: 313, 417. 



Several fragments at St. 313 ; one only at St. 417. 



55. Reophax micaceus, Earland (A 143). 

 One station: 303. 



A single typical specimen. 



56. Reophax nodulosus, Brady (F 84A) (SG 103) (A 145). 



Eighteen stations: 226, 282, 286, 290, 295, 300, 301, 303, 313, 387, 391, 406, 417, 418, 421, 422, 

 428, 438. 



One of the most typical species of the Weddell Sea deposits, found in more or less 

 abundance in nearly all the soundings, generally in a fragmentary condition. Most of 

 the fragments were of small specimens, probably not exceeding 3-4 mm. in length. In 

 the trawl washings from St. 313 perfect specimens up to 5 mm. in length were frequent, 

 they were regular and neatly constructed. At St. 417 the species reaches a gigantic size, 

 the largest fragment was 16 mm. in length, and if perfect the specimen would have 

 exceeded 25 mm. These large individuals are probably very old, they are coarsely con- 

 structed of large sand grains, and the chambers are elongate with constricted sutures. 



Pearcey: 301, 313, 416, 417, 418, 420, 447. He notes the abundance and large size of 

 the specimens at St. 417 "several measuring more than one inch in length".
