SYSTEMATIC ACCOUNT 41 



The discovery of Miliammma in the extreme south of the Weddell Sea is a note- 

 worthy extension of the range of the genus, and my comments on the subject in the 

 previous report (A, pp. 11, 24) require modification. The species may be found larger 

 and better developed whenever material from shallower water in the Weddell Sea be- 

 comes available for examination. In any case the present discovery closes part of the 

 long gap in the circumpolar records and, but for its absence from the records of the 

 German South Polar expedition, the genus might be included among those having a 

 circumpolar distribution. Such may eventually prove to be the case. 



Family TEXTULARIIDAE 

 Subfamily SPIROPLECTAMMININAE 

 Genus Spiroplectammina, Cushman, 1927 



105. Spiroplectammina filiformis, Earland (A 224). 

 Three stations: 280, 303, 312. 



Single specimens at Sts. 280 and 303 ; four examples at St. 312. They are all typical 

 as regards form, but not so deeply ferruginous as the type, the colour varying between 

 light grey and brown. All the stations are in the central area of the Weddell Sea in very 

 deep water, 1956-2547 fathoms. 



Subfamily TEXTULARIINAE 

 Genus Textularia, Defrance, 1824 



106. Textularia catenata, Cushman (A 228). 

 Four stations: 417, 421, 438, 447. 



Very rare at St. 438 ; frequent to common at the other stations. 



107. Textularia tenuissima, Earland (SG 156) (A 229) 

 Seven stations: 303, 312, 313, 338, 406, 417, 447. 



Common at Sts. 312 and 313; frequent at St. 417; more or less rare elsewhere. 

 The specimens are characteristic everywhere but vary greatly in size: small at St. 312, 

 very large at St. 417, large at most other stations. 



Pearcey's only records of Textularia within the convergence are T. contca, d'Orbigny 

 and T. concava (Karrer) from St. 342 in the Scotia Sea. I have not seen either of these 

 species. It is difficult to understand how he can have overlooked the genus in the 

 Weddell Sea material. He records Gaudryina pseudofiliformis, Cushman, at Sts. 313 and 

 338, and in the previous report (A, p. 11) I suggested that this record might refer to 

 Gaudryina apicularis, Cushman, which had been found in the deep water of the Scotia 

 Sea. Having met with neither of these species of Gaudryina in the Weddell Sea, I am 

 now inclined to the opinion that Pearcey's record may refer to Textularia tenuissima, 

 which occurs at both stations mentioned by him.
