72 DISCOVERY REPORTS 



layer" figured by Heron-Allen and Earland in 1917 (H.-A. and E. 1912, etc., NSG, 

 1917, pi. xxix, fig. 5) cannot be compared with T. spumosa in the size of its vesicles. 

 T. cariosa occurs in the Discovery material, but with the exception of St. 181, its dis- 

 tribution is different. 



107. Thurammina murata, Heron-Allen and Earland (Plate H, fig. 11). 



Thurammina papillata var. murata, Heron-Allen and Earland, 1912, etc., NSG, 1917, p. 549, 

 pi. xxviii, figs. 18-21. 



One station: WS 517. 



A single quite typical specimen from 2770 m. in the Bellingshausen Sea. Its occur- 

 rence so far from the original, and so far as I know the only recorded localities, in the 

 Faroe-Shetland Channel, adds one more to the mysteries of distribution in the Fora- 

 minifera. 



108. Thurammina protea, Earland (SG 76). 



Nine stations: 167, 170, 177, 181, 182, 190, 196; WS 482, 494A. 



Frequent at Sts. 182 and 190 in the Palmer Archipelago, but rare elsewhere. Both 

 sessile and free specimens were observed, and in some cases the free specimens indicate 

 by their shape that they have developed inside the cavity of Hyperamtnina subnodosa, or 

 some other tubular organism. 



This species may prove to be identical with Thurammina irregularis, Wiesner (W. 193 1 , 

 FDSE, p. 83, pi. vi, figs. 62-4), in which case Wiesner's name has priority. The figures 

 are very similar, but Wiesner says his specimens have no apertures, whereas they are 

 generally distinct in T. protea. His description of his species is: "Test of variable, 

 generally irregular shape, shell wall thin, built of tiny flat sand grains with more or less 

 cement. Oral papillae absent, apertures not perceptible. Colour light brown". 



T. protea has recently been recorded from 280 fathoms in the Bay of Whales, Ross 

 Sea, by A. S. Warthin (W. 1934, FRS, p. i). 



109. Thurammina tuberosa, Haeusler (SG 77). 

 Two stations: 190; WS 385. 



Two small specimens probably referable to Haeusler's species were found at St. 

 WS 385 in the Bransfield Strait, depth 1838 m., and one at St. 190 in the Palmer 

 Archipelago, depth 93-130 m. They resemble the simple aggregations described from 

 South Georgia. 



Sub-family RHABDAMMININAE 

 Genus Jaculella, Brady, 1879 

 no. Jaculella acuta, Brady (F 69) (Plate H, figs. 19, 20). 

 Eight stations : 170, 177, 362, 363 ; WS 494A, 507B, 511, 517. 



Always very rare, but the few stations at which it was recorded are spread over the 

 whole area from the South Sandwich Islands (St. 363) to the Bellingshausen Sea, and 

 the depths range between 329 and 3370 m. Most of the specimens are small or very 

 small, but at St. 170 two large tests were found. At St. 363 a small individual, 1-2 mm.
