210 MESSES. E. HEKON-ALLEN AND A. EAELAND ON THE 



22. Miliolina suborbicularis (d'Orbigny). (Plate 39. figs. 7-9.) 



TrUoculina suborbicularis, d'Orbigny, 1839, FC. p. 176, pi. x. figs. 9-11. 

 Miliolina suborbicularis, Heron-Allen & Earland, 1908, etc., SB. 1911, p. 304.. 



1 Station. 



A single specimen, which we figure, from Stn. 10. Its occurrence serves to clear up 

 any doubt which we implied in recording the species as recent from Selsey Bill, which 

 was the first British record. 



23. Miliolina trigonula (Lamarck). 



Miliolites trigonula, Lamarck, 1804, AM. vol. v. p. 351. No. 3. 

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



15 Stations. 



Generally distributed and very abundant and finely developed at Stns. 10, 14, and 19. 

 Throughout the dredgings the specimens are remarkably consistent in character, agreeing 

 perfectly with d'Orbigny's figure and Modele No. 94 (d'O. 1826, TMC. p. 299. No. 7). 



24. Miliolina tricarinata (d'Orbigny). 



TrUoculina tricarinata, d'Orbigny, 1826, TMC. p. 299. No. 7, Modele No. 94. 

 Miliolina tricarinata, Brady, 1884, FC. p. 165, pi. iii. fig. 17. 



13 Stations. 



Fairly generally distributed. All the specimens are of the regular sharp-edged type, 

 except at Stn. 18, where the species is most abundant and reaches good dimensions. At 

 this Stn. also, and at Stn. 6, some of the individuals show a tendency to depart from the 

 usual regularity of construction and to approach 31. (TrUoculina) plicata of Terquem 

 (T. 1878, FIR. p. 61, pi. vi. fig. 3), recently figured by us from East Africa (H.-A. & E. 

 1914, etc., FKA. 1915, p. 562, pi. xli. figs. 17-22). 



25. Miliolina bosciana (d'Orbigny). 



Quinqueloculina bosciana, d'Orbigny, 1839, FC. p. 191, pi. xi. figs. 22-24. 

 Miliolina bosciana, Millett, 1898, etc., FM. 1898, p. 267, pi. vi. fig. 1. 



8 Stations. 



Much less abundant or widely distributed than the allied species M. oblong a, but good 

 and typical examples occur at many Stns., especially Stn. 4. A thin-shelled opalescent 

 type occurs at Stn. 12, and more rarely at Stn. 18, similar to the hyaline specimens of 

 II. oblonga referred to under that species. Previously recorded as British only by Mills 

 from the Humber (Trans. Hull Sci. etc. Soc. vol. i. p. 141, pi. x. fig. 17) and by us from 

 Clare Island (H.-A. & E. 1913, CI. p. 25), but has no doubt been included by many 

 authors under M. oblonga. 



20. Miliolina oblonga (Montagu). 



Vermicu/um oblongum, Montagu, 1803-8, TB. p. 522, pi. xiv. fig. 9. 

 Miliolina oblonga, Brady, 1884, FC. p. 160, pi. v. fig. 4 a, b.
