EXPLANATION OF PLATE 84 (LXXXIV) 



All figures X 50. 

 Figures 1-7. — Sphaeroidina bulloides d'Orbigny. 



Fig. 1. Challenger Sta. 323, South Atlantic. (1900 fathoms) 

 Figs. 2, 5-7. Challenger Sta. 120, off Pernambuco, Atlantic. (675 fathoms) 

 Figs. 3, 4. Challenger Sta. 279A, off Tahiti, Pacific. (420 fathoms) 

 According to Cushman and Todd (C.C.L.F.R., Vol. 25, Ft. 1, 1949, p. 21) figures 3, 4, 6 and 7 are probably 

 not 5. bulloides and the material needs restudying. 

 Figures 8-11. — Sphaeroidinella dehiscens (Parker and Jones). 



Figs. 8, 9, 11. Challenger Sta. 224, North Pacific. (1850 fathoms) 

 Referred by Brady to Sphaeroidina and by Cushman to Sphaeroidinella, as the genotype (C.C.L.F.R., Vol. 

 3, Pt. 1, p. 90). 

 Figures 12, 13. — Pullenia bulloides (d'Orbigny). 



Fig. 12. Challenger Sta. 224, North Pacific. (1850 fathoms) 

 Fig. 13. Challenger Sta. 332, South Atlantic. (2200 fathoms) 

 Referred by Brady to Pullenia sphaeroides (d'Orbigny). Cushman and Todd (C.C.L.F.R., Vol. 19, Pt. 1, 

 p. 13) refer Brady's figures to P. bulloides (d'Orb.) and suggest that d'Orbigny 's name sphaeroides, as a Pullenia, 

 should be allowed to lapse. 

 Figures 14, 15. — Pullenia subcarinata (d'Orbigny). 



Fig. 14. Challenger Sta. 1491, Kerguelen Islands, Pacific. (120 fathoms) 

 Fig. 15. Challenger Sta. 145, Prince Edward Island, S. Pacific. (50-150 fathoms) 

 Referred by Brady to Pullenia quinqueloba (Reuss) and retained as such by Cushman and Todd (1. c. supra, 

 1943, p. 11). Heron-Allen and Earland, however (Discovery Reports, Vol. 4, Foraminifera Part I, 1932, p. 

 403), have stated that the Falkland Islands form is P. subcarinata (d'Orbigny), that d'Orbigny's came from 

 that region and also show both five- and six-chambered tests. They reached the conclusion that P. quinqueloba 

 (Reuss) is a synonym of P. subcarinata (d'Orbigny). 

 Figures 16-20. — Pulleniatina obliquiloculata (Parker and Jones). 



Figs. 16, 20. Challenger Sta. 224, North Pacific. (1850 fathoms) 

 Fig. 17. Challenger Sta. 5, Atlantic, S. W. of the Canaries. (2740 fathoms) 

 Fig. 19. Challenger Sta. 344, Ascension Island, mid-Atlantic. (420 fathoms) 

 Referred by Brady to Pullenia and by Cushman (C.C.L.F.R., Vol. 3, Pt. 1, 1927, p. 90) to Pulleniatina, 

 as genotype.
