TEXTULARIIDAE 119 



Length up to 1-30 mm. or more; breadth and thickness at oral extremity up to 

 0-40 mm. 



This striking species has an extremely restricted distribution, being confined to three 

 stations which, however, are some distance apart. It is not uncommon at St. 170, rarer 

 elsewhere. St. 175 is in the Bransfield Strait; St. 170 is at Clarence Island, and St. 363 

 in the South Sandwich Islands. The depths range between 200 and 342 m. It is very 

 remarkable that it was not seen at any of the intermediate stations. V. superba belongs 

 to the group of V. scabra (Williamson) (No. 237) but cannot be confused with that 

 species. In its graceful outline, inflated chambers and deep sutures, it is not unlike 

 fig. 14 A of Verneuilifia schisea, Cushman and Alexander (in C. 1925, etc., LFR, 1930, 

 p. 9, pi. ii, figs. 13, 14) from the Lower Cretaceous of Texas, but is more than double 

 the size of that species (length o-6o mm.). 



239. Verneuilina advena, Cushman (F 121) (SG 159). 



Fourteen stations: 162, 171, 192, 194, 196, 204, 209, 366; Port Lockroy; WS 389, 395, 480, 485, 

 509- 



Frequent at Sts. 192, Port Lockroy and WS 395, rare or very rare elsewhere. The 

 specimens are identical with those described and figured in the South Georgia report. 

 The depths range from "anchor mud" at Port Lockroy to 1542 m. at St. 171. 



240. Verneuilina minuta, Wiesner (Plate V, figs. 22-26). 



Verneuilina minuta, Wiesner, 1931, FDSE, p. 99, pi. xiii, fig. 155, pi. xxiii. Stereo-fig. d. 



Thirty-two stations: 169, 171, 175, 177, 180, 181, 186, 191, 196-8, 203, 360, 363; 62° 50' S, 

 60° 20' 30" W; WS 383-5, 395, 471, 472, 479, 480, 483-7, 494A, 498, 512, 515. 



Widely distributed from the South Sandwich Islands to the Bellingshausen Sea, in 

 depths between 160 and 3580 m. The only station at which it is common is St. 177 in 

 the Bransfield Strait, 1080 m. ; it is frequent at Sts. 196, WS 395 and 479 ; more or less 

 rare elsewhere. 



V. minuta is a very distinctive little species, distinguishable from V. advena by its 

 somewhat larger size, its rough surface due to the small quantity of cement employed, 

 and its regular conical outline. The last convolution is cut ofi" abruptly, the chambers 

 not being rounded off as in V. advena. The sutural lines are flush and obscure. 



Wiesner 's specimens were from 66° 2' S, 89° 38' E, 385 m. His description of the 

 species is as follows: "Very small, with 4-5 convolutions, the arched chambers broader 

 than high. Outer surface rough ". He remarks that it is distinguishable from the related 

 forms V. polystropha (= I', scabra, No. 237) and V. advena by its trifling size, and its 

 solid regular form. Wiesner has been so good as to examine some of the Discovery 

 specimens, and confirm their identification. 



There is considerable variation in the size of the species at different stations. At Sts. 

 175 and 181 some specimens were found nearly double the general average, which is 

 about 0-2 mm. long and o-i mm. greatest breadth. Long-narrow and short-broad 

 forms also occur as in V. scabra and V. advena.
