HAUERININAE 321 



Planispiiina celata, Flint, 1899, RFA, p. 303, pi. xlvii, fig. 5. 

 Sigmoiliiia schlumbcrgeri, Silvestri, 1904, TB, p. 267. 



Three stations: 236; WS 215, 413. 



A few specimens identifiable with Brady's figures ascribed to Plauispirina celata 

 (Costa). Silvestri has separated these and named them after Schlumberger, who has 

 gone in great detail into the minute structure of the form {ut supra). While preserving 

 Silvestri's name/)ra tern., we may say we have been unable to verify the existence of a 

 microspheric form in Sigmoilina celata (Costa), sensii stricto. We have cut sections of a 

 considerable number of specimens of both forms and found that S. schliimbergeri is, in 

 our experience, invariably microspheric and S. celata megalospheric. 



40. Sigmoilina tenuis (Czjzek). 



Ouinqiielociilina tenuis, Czjzek, 1848, FWB, p. 149, pi. xiii, figs. 31-4. 



Spiroloadina tenuis, Brady, 1884, FC, p. 152, pi. x, figs. 7-11. 



Sigmoilina tenuis, Schlumberger, 1887, P, p. 118. 



Spii-oloculina tenuis, Heron-Allen and Earland, 1916, FWS, p. 208 (and sub M. pygmaea, 



p. 211, pi. xxxix, figs. 17-18). 



Three stations: WS 217, 221, 408. 



Fairly frequent at WS 217 and 408, where the specimens exhibit a great range of 

 torm, extending from the typical Ouiiiqueloculiiia tenuis, Czjzek, with its somewhat 

 narrow outline and marked sigmoid curves, to the very complanate Spirolociilina tenuis- 

 sima, Reuss (R. 1867, FSW, p. 71, pi. i, fig. 11), in which the sigmoid curves are 

 hardly recognizable. We have dealt with the relationships of this form with Miliolina 

 pygmaea (Reuss) in our West of Scotland paper {loc. cit., p. 211). 



Sub-family HAUERININAE 



Genus Tubinella, Rhumbler, 1906 



41. Tubinella funalis (Brady). 



Articidina funalis, Brady, 1884, FC, p. 185, pi. xiii, figs. 6-11. 



Tubinella funalis, Rhumbler, 1906, FLC, p. 26. 



Tubinella funalis, Cushman, 1918, etc., FAO, 1929, pt. 6, p. 54, pi. xii, fig. 8. 



Five stations: 48, 53, 388; WS 71, 88. 



A few specimens at each. Three of these stations, 48, 53 and WS 71, are close 

 together in-shore to the north-east of the islands, WS 88 is far away (our furthest south- 

 west station) close to the point of South America and 388 is right oflF Cape Horn. Its 

 non-occurrence at intermediate stations is difficult to explain, as the species is abundant 

 in Antarctic material, and, if occurring at all, would be expected to be universally 

 distributed in the area.
