EXPLANATION OF PLATE 53 (LIII), CONTINUED 



Figures 10, 11. — Bolivina subaenariensis Cushman var. 



Fig. 10b. Porcupine Sta. 17, West of Ireland, N. Atlantic. (1230 fathoms) 

 Figs. 10a, 11. Porcupine Sta. 11, West of Ireland, N. Atlantic. (1630 fathoms) 

 Referred by Brady to B. aenariensis (Costa) and by Cushman (C.L.F.R. Spec. Publ. No. 9, 1937, p. 156) 

 to B. subaenariensis Cushman var. 

 Figures 12, 13. — Bolivina decussata Brady. 



Challenger Sta. 300, North of Juan Fernandez, E. Pacific. (1375 fathoms) 

 Figures 14, 15. — Loxostomum sp. nov. 



Fig. 14. Challenger Sta. 219A, Admiralty Islands, Pacific. (17 fathoms) 

 Fig. 15. Challenger Sta. 279C, off Tahiti, Pacific. (620 fathoms) 

 Referred by Brady to Bolivina nobilis Hantken. This is regarded as quite distinct from Hantken's species 

 from the European Eocene and belonging to the genus Loxostomum rather than to Bolivina. As far as can be 

 ascertained it appears to be undescribed. 

 Figures 16-18. — Bolivina hantkeniana Brady. 



Fig. 16. Challenger Sta. 279A, off Tahiti, Pacific. (420 fathoms) 

 Fig. 17. Challenger Sta. 279C, off Tahiti, Pacific. (620 fathoms) 

 Figures 19-21. — Loxostomum karrerianum (Brady). 



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

 Referred by Brady to Bolivina and by Cushman (C.L.F.R., Spec. Publ. No. 9, 1937, p. 184) to Loxostoma 

 {Loxostomum). 

 Figures 22, 23. — Loxostomum lobatum (Brady). 



Challenger Sta. 219A, Admiralty Islands, Pacific. (17 fathoms) 

 Referred by Brady to Bolivina and by Cushman (1. c. supra, 1937, p. 188) to Loxostomum. 

 Figures 24, 25. — Bolivina schwageriana Brady. 



Challenger Sta. 217A, off Papua, Pacific. (37 fathoms) 

 Figures 26, 27. — Bolivina semicostata Cushman. 



Challenger Sta. 185, Torres Strait, Pacific. (155 fathoms) 

 Referred by Brady to Bolivina costata d'Orbigny and by Cushman (U.S.N.M. Bull. 71, Pt. 2, 1911, p. 43) 

 to B. semicostata new name. 

 Figures 28, 29. — Loxostomum amygdalaeformis (Brady). 



Challenger Sta. 209, Philippines, N. Pacific. (95-100 fathoms) 

 Referred by Brady to Bolivina and transferred by Cushman (C.L.F.R. Spec. Publ. No. 9, 1937, p. 183) 

 to Loxostomum. 

 Figures 30, 31. — Bolivina subreticulata Parr. 



Challenger Sta. 177, New Hebrides, S. Pacific. (125 fathoms) 

 Referred by Brady to B. reticulata Hantken and by Parr (Proc. Roy. Soc. Victoria, n.s.. Vol. 44, 1932, p. 12) 

 to B. subreticulata nov. 

 Figures 32, 33. — Bolivinita subangularis (Brady). 



Challenger Sta. 209, Philippines, N. Pacific. (95-100 fathoms) 

 Referred by Brady to Bolivina and transferred to Bolivinita by Thalmann (Eclog. geol. Helvet., Vol. 30, 

 1937, No. 2, p. 341) 



EXPLANATION OF PLATE 54 (LIV) 



Figs. 1-3, 5-16, X 75; Figs. 4, 17, 18, X 60. 

 Figure 1. — Cassidulina teretis Tappan. 



Porcupine Sta. 11, West of Ireland, North Atlantic. (1630 fathoms) 

 Referred by Brady to C. laevigata d'Orbigny, and by Loeblich and Tappan (Smith. Misc. Coll., Vol. 121, 

 No. 7, 1953, p. 121) to C. teretis Tappan 1951. They also refer figures 2 and 3 to this species but the smaller 

 size and marked keel appears to differentiate these. 

 Figures 2, 3. — Cassidulina carinata Silvestri? 



Fig. 2. Challenger Sta. 167, New Zealand. (150 fathoms) 

 Fig. 3. Porcupine Sta. 11, N. Atlantic. (1630 fathoms) 

 Referred by Brady to C. laevigata d'Orbigny. Fig. 3 was referred by Phleger, Parker and Peirson (Swedish 

 Deep-Sea Exped., 1947-48, Vol. 7, 1954, p. 44) to C. carinata Silvestri. Both figures 2 and 3, however, show 

 a similar keeled development and small, compressed test. The identity with carinata Silvestri is queried and 

 it is thought that Brady's specimens should be compared with C. laevigata var. carinata Cushman (i.e. Cassi- 

 dulina neocarinata Thalmann). 

 Figures 4, 5. — Cassidulina crassa d'Orbigny. 



Fig. 4. Challenger Sta. 151, off Heard Island, S. Pacific. (75 fathoms)
