138 DISCOVERY REPORTS 



Genus Cassidulinoides, Cushman, 1927 



292. Cassidulinoides parkerianus (Brady) (F 163) (SG 190). 



Nineteen stations: 170, 175, 180, 181, 195, 196, 200, 201, 206, 363, 366; WS 382, 474, 476, 482, 

 488, 490, 493, 494 A. 



Generally distributed over the entire area, with the exception of the most southerly 

 stations of the Bellingshausen Sea and the deep water of the Drake Strait and Scotia 

 Sea. It is common and very well developed at St. 170 in 342 m. off Clarence Island; 

 frequent and equally good specimens at Sts. WS 382 and 482 in the Bransfield Strait. 

 Very good and typical specimens at Sts. 363 and 366 in the South Sandwich Islands, 

 where it is rare. Rare to very rare at the remaining stations. It appears to be most at 

 home at less depths than 500 m., there being few records over that depth, and only one 

 in deep water, at St. WS 474, 2813 m., where it is very rare. 



Genus Ehrenbergina, Reuss, 1850 



293. Ehrenbergina pupa (d'Orbigny) (F 164) (SG 191). 

 Nine stations: 177, 196, 198, 200, 363, 387; WS 474, 482, 486. 



Rare or very rare everywhere, except at St. 196 in the South Shetlands, depth loi i m., 

 where many specimens were observed. The stations, which are scattered over a large 

 area in the South Sandwich Islands, Scotia Sea, Drake Strait, and Bransfield Strait, 

 have a great range of depth between 50 and 3102 m., but all the specimens are of the 

 short, subglobular type described in the Falklands report (F 164), and figured on pi. ix, 

 figs. 41-3 in that report. 



294. Ehrenbergina bradyi, Cushman (F 166) (SG 194). 

 Nine stations: 383-7; WS 204, 403, 468, 469. 



Excellent specimens were frequent at Sts. 384, 385, 386 and WS 469, and frequent 

 but smaller at St. WS 403 ; rare or very rare elsewhere. All the stations are in the deep 

 water of the Drake Strait between 3102 and 4773 m., and several are outside the 

 Antarctic convergence line. 



295. Ehrenbergina hystrix, Brady (Plate VI, figs. 33-35). 



Ehrenbergina hystrix, Brady, 1879, etc., RRC, 1881, p. 60; 1884, FC, p. 434, pi. Iv, figs. 8-11. 

 Ehrenbergina hystrix, Cushman, 1910, etc., FNP, 191 1, p. 102, fig. 156. 

 Ehrenbetgifia hystrix, Heron-Allen and Earland, 1922, TN, p. 140. 

 Ehrenbergina hystrix, Cushman, 1927, E, p. 3, pi. i, fig. 6. 



Five stations: 383-6; WS 403. 



Good specimens were frequent at St. 385, rare or very rare at the other stations. They 

 are all in the deep water of the Drake Strait between 3638 and 4773 m. This is a Pacific 

 species, and Cushman (1927, supra) says that its "known distribution is in the tropical 

 Pacific from nearly 140° W to nearly 140° E, and extending barely beyond the Tropics. 

 An exception to this are the specimens recorded by Heron-Allen and Earland from the 

 Antarctic, south of New Zealand. The average of all known records gives about 2000 

 fathoms". The Discovery records are therefore of interest as marking an extension of
