27. Miliolina trigonula (Lamarck). 



Miliolites trigonula, Lamarck, 1804, etc., AM, 1804, v, p. 351, no. 3. 

 Tnloculina trigonula, d'Orbigny, 1826, TMC, p. 299, no. i, pi. xvi, figs. 5-9. 

 Miliolina trigonula, Brady, 1884, FC, p. 164, pi. iii, figs. 14-16. 



Four stations: WS 88, 99, 215, 217. 



Rare. There are but few specimens at each station and they occur in two different 

 forms, differing in their length. The long form appears at WS 88 and 217 and the short 

 broad form at WS 99 and 215. 



28. Miliolina tricarinata (d'Orbigny). 



Triloculina tricarinata, d'Orbigny, 1826, TMC, p. 299, no. 7, Modele no. 94. 

 CrncilocuUna triangularis, d'Orbigny, 1839, FAM, p. 72, pi. ix, figs. 11 and 12. 

 Triloculina tricarinata, Brady, 1864, RFS, p. 466, pi. xlviii, fig. 3. 



Four stations: 388; WS 245, 248, 433. 



A few specimens at these stations. D'Orbigny recorded his Cruciloailina triangularis 

 {lit supra), which has always been regarded as a synonym of M. tricarinata, as being 

 fairly common in deep water off the Falkland Islands, on stony ground. None of our 

 Falkland specimens are characterized by the cruciform aperture which gave rise to his 

 generic name, but are normally milioline. In the South Georgia area, however, the 

 cruciloculine aperture is normal and frequent. The Type of Cniciloculina was not to 

 be found in Paris. 



29. Miliolina circularis (Bornemann). 



Triloculina circularis, Bornemann, 1855, FSH, p. 349, pi. xix, fig. 4. 



Miliolina circularis, Brady, 1884, FC, p. 169, pi. iv, fig. 3 ; pi. v, figs. 13, 14 (?). 



Fifteen stations: 48, 51, 53, 388; WS 71, 79, 83, 87, 88, 90, 93, 94, 95, 108, 213. 



The specimens are generally rather small and feeble. Good at 53, 388 and WS 87. 

 A fossil specimen was observed at WS 95. 



30. Miliolina seminuda (Reuss). 



Quinqueloculina seminuda, Reuss, 1866, FABS, p. 125, pi. i, fig. 11. 

 Miliolina suhrotunda, Wright, 1885-6, BLP, p. 319, pi. xxvi, fig. 5. 

 Miliolina seminuda, Heron-Allen and Earland, 1913, CI, p. 27. 



One station: WS 531. 



A single weakly marked specimen only. 



31. Miliolina rosea (d'Orbigny) (Plate VI, figs. 16-18). 

 Triloculina rosea, d'Orbigny, 1839, FAM, p. 69, pi. iii, figs. i8-io. 



One station : WS 93. 



A few specimens, white in colour, from this station. In spite of his specific name, 

 d'Orbigny describes his specimens as being uniformly pink or white. One specimen 

 shows, by the presence of a few feeble striae on the periphery, the relationship to
