MILIOLIDAE 49 



specimens are identical with the figure of Cnicilociilina triangularis, d'Orbigny, recorded 

 by him from the Falkland area, but which was not discovered in the Falkland material. 

 The accompanying figure illustrates some of the range of variation in the aperture. 



Wiesner has recorded as a new variety, M. tricarinata var. crucioralis (W. 193 1, 

 FDSE, p. 105) what is apparently a typical CniciloaiJina triangularis, d'Orbigny. 

 Wiesner does not figure his specimens, but the description is of an identical organism. 



21. Miliolina circularis (Bornemann) (F 29). 



Six stations: 123, 126, 144, 145; WS 27, 28. 



Except at WS 27, where small specimens are common, the species is very rare. Seldom 

 more than a single specimen, which is often a large one, at each station. Very large at 

 Sts. 126 and 144. 



Genus Sigmoilina, Schlumberger, 1887 



22. Sigmoilina obesa, Heron-Allen and Earland (F 38). 

 One station : WS 27. 



A single specimen only. 



23. Sigmoilina tenuis (Czjzek) (F 40). 

 Four stations: WS 334, 353, 429, 521. 



Very rare everywhere, but exhibiting the same range of convexity as in the Falkland 

 area. 



Sub-family HAUERININAE 

 Genus Tubinella, Rhumbler, 1906 



24. Tubinella funalis (Brady) (F 41). 

 Six stations: 30, 123, 149; WS 25, 27, 33. 



Rare everywhere, but large and typical specimens at Sts. 123, 149, WS 27. Wiesner 

 (FDSE, i93i,pp. 67, i09,pl. i,fig. 6; pl.xv, fig. 183 ;pl.xvi,figs. 184-5) has made this 

 species the type of a new genus TubineUi)w, on the grounds of a suspected relationship 

 with Tiihinella perforata, Rhumbler (FLC, 1906, p. 27, pi. ii, fig. 5). But the similarity 

 appears to be external only. Rhumbler 's species is distinctly perforate, and if really a 

 foraminifer, would be widely separated from T. funalis, which exhibits no sign of 

 perforation of the wall. Rhumbler would appear to have assigned his specimen to 

 Tubinella, akin to Articulina, largely because he supposed the specimen figured by 

 Millett under the name Articulina funalis var. inornata (Millett, 1898, etc., FM, 1898, 

 P- 5^3' pl- xii, fig. 1 1) to indicate signs of perforation. Millett's type specimens are in the 

 H.-A. and E. collection and I have subjected them to an examination under a high power. 

 Their nature appears to be rather uncertain, but they are not perforate. The markings 

 shown in Millett's drawing are foreign bodies, some being food particles.
