EXPLANATION OF PLATE 6 (VI) 



Figs. 1, 2, X 50; Figs. 3-5, X 45; Figs. 6-8, X 50; Fig. 9, X 40; Fig. 10, X 50; Figs. 11, 12, X 35; 

 Fig. 13, X 25; Figs. 14-20, X 35. 

 Figures 1, 2. — P seudomassilina australis (Cushman). 



Challenger Sta. 187A, Booby Island, Torres Strait, Pacific. (8 fathoms) 

 Referred by Brady to Massilina secans (d'Orbigny) and by Lacroix (Bull. I'lnst. Oceanogr. Monaco, No. 

 750, 1938, p. 2) to M. australis Cushman. Lacroix later (1. c, No. 754, 1938, p. 3) transferred this species to 

 P seudomassilina. Cushman (Carnegie Inst. Washington, Publ. 342, 1924, p. 66) noted that Brady's figures 

 were very close to his M. pacificensis, also a P seudomassilina according to Lacroix. A third species closely 

 allied is Massilina agglutinans (Keijzer, Temninckia, Vol. 1, 1936, p. 120) which may prove to be a variety 

 of P. australis. 

 Figures 3-5. — Miliolinella labiosa (d'Orbigny). 



Figs. 3, 5. Challenger Sta. 135, off Tristan d'Acunha, Atlantic. (100-150 fathoms) 

 Fig. 4. Challenger Sta. 306, W. of Patagonia, Pacific. (345 fathoms) 

 Referred by Brady to Miliolina and by Wiesner (Deutsche Siidpolar Exped. 1901-1903, Vol. 20 (Zool., 

 Vol. 12), 1931, p. 108) to Miliolinella. 

 Figures 6-8. — Quinqueloculina bradyana Cushman. 



Figs. 6, 7. Challenger Sta. 162, Bass Strait, Pacific. (38-40 fathoms) 

 Fig. 8. Challenger Sta. 260A, off Honolulu reefs. Pacific. (40 fathoms) 

 Referred by Brady to Miliolina undosa (Karrer) and by Cushman (U.S.N.M., Bull. 71, Pt. 6, 1917, p. 52) 

 to Quinqueloculina bradyana. 

 Figure 9. — Quinqueloculina bicornis (Walker and Boys). 



Porcupine Sta. AA, off Skye, N. Atlantic. (45-60 fathoms) 

 Referred by Brady to Miliolina and by Cushman and others to Quinqueloculina. 

 Figure 10. — Quinqueloculina amygdaloides (Brady). 



Challenger Sta. 232, South of Japan. (345 fathoms) 

 Referred by Brady to Miliolina and by Cushman (U.S.N.M., Bull. 71, Pt. 6, 1917, p. 51) to Quinqueloculina. 

 Figures 11, 12. — Quinqueloculina intricata Terquem. 



Porcupine Sta. AA, off Skye, Scotland, N. Atlantic. (45-60 fathoms) 

 Referred by Brady to Miliolina bicornis (Walker and Boys) and by Thalmann (Eclog. geol. Helv., Vol. 25, 

 No. 2, 1932, p. 296) to Quinqueloculina intricata Terquem. 

 Figures 13, 14. — Quinqueloculina pulchella d'Orbigny. 

 Fig. 13. West of Scotland, Atlantic. 



Fig. 14. Porcupine Sta. AA, off Skye, Scotland, Atlantic. (45-60 fathoms) 

 Referred by Brady to Miliolina and by d'Orbigny to Quinqueloculina. 

 Figures 15-20. — Quinqueloculina granulocostata Germeraad. 



Figs. 15, 17, 19, 20. Challenger Sta. 260A, off Honolulu, Pacific. (40 fathoms) 

 Fig. 16. Challenger Sta. 218A, Admiralty Islands, Pacific. (16-25 fathoms) 

 Fig. 18. Challenger Sta. 187A, off Booby Island, Pacific. (8 fathoms) 

 Referred by Brady to Miliolina linnaeana (d'Orbigny), a triloculine species from Cuba. Germer-^ad (Geol. 

 Central Seran, 1946, Amsterdam, p. 63) has pointed this out and proposed the name Quinqueloculina granulo- 

 costata for the Pacific species figured by Brady.
