EXPLANATION OF PLATE 51 (LI), CONTINUED 



Referred to P. rapa Gumbel by Brady and to P. rapa var. recens by Dervieux (Boll. Soc. Geol. Ital., Vol. 

 18, 1899, p. 76). 

 Figure 22. — Pleurostomella acuminata Cushman. 



Challenger Sta. 192, Ki Islands, C. Pacific. (129 fathoms) 

 Referred by Brady to P. alternans Schwager and by Cushman (U.S.N. M. Bull. 104, Ft. 3, 1922, p. 50) to 

 P. acuminata, recorded by Cushman from the Caribbean in 821 fathoms. 

 Figure 23. — Pleurostomella sp. nov. 



Challenger Sta. 192, Ki Islands, C. Pacific. (129 fathoms) 

 Referred by Brady to P. alternans Schwager. Search through the available literature has failed to reveal any 

 species which compares closely with Brady's figures 23a, b, and they are believed to represent a new species. 



EXPLANATION OF PLATE 52 (LII) 



Figs. 1-3, 10, 11, 20-21, 23-25, 31-34, X 70; Figs. 4, 5, 29, 30, X 80; Figs. 6, 14-17, X 40; Figs. 7-9, 12, 13, 

 22, 26-28, X 50; Figs. 18, 19, X 60. 

 Figures 1, 3. — Virgulina davisi Chapman and Parr. 



Challenger Sta. 276, South Pacific. (2350 fathoms) 

 Referred by Brady to V. schreibersiana Czjzek and to V. davisi by Chapman and Parr (Australasian Ant- 

 arctic Exped. 1911-1914, Sc. Rep., Ser. C, Vol. 1, No. 2, 1937, p. 88). 

 Figure 2. — Cassidella pacifica Hofker? 



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

 Referred by Brady to V. schreibersiana Czjzek. This figure is very close to V. complanata Egger, especially 

 as figured by Cushman (U.S.N. M. Bull. 161, Pt. 3, 1942, and in C.L.F.R., Spec. Publ. No. 9, 1937, pi. 4, fig. 

 15). Hofker (Siboga Exp. Foraminifera Pt. 3, 1951, p. 273) refers this figure of Cushman to Cassidella pacifica 

 but does not refer to Brady. He also refers Egger's complanata to this genus but his figures are totally different 

 from those of Egger and it may be that Brady's figure is Cassidella complanata (Egger). Cushman (1. c. supra, 

 1937, p. 14) notes that Brady's fig. 2 is "probably to be referred to Bulimina" but does not amplify this state- 

 ment. 

 Figures 4, 5. — Virgulina pauciloculata Brady. 



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

 Figures 6. — Virgulina texturata Brady. 



Challenger Sta. 296, South Pacific. (1825 fathoms) 

 Figures 7, 8. — Cassidulinoides sp.? 



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

 Referred by Brady to Virgulina subsquamosa Egger, and tentatively by Cushman (U.S.N.M. Bull. 104, 

 Pt. 3, 1922, p. 115) to V. bradyi, a Western Atlantic species. These figures appear to represent Cassidulinoides. 

 Figures 9. — Virgulina bradyi Cushman. 



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

 Referred by Brady to V. subsquamosa Egger and by Cushman (1. c. supra, 1922, p. 115) to F. bradyi, Brady's 

 figures differ from those of Egger. 

 Figures 10, 11. — Virgulina rotundata Parr. 



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

 Referred by Brady to V. subsquamosa Egger and by Parr (B.A.N. Z. Antarctic Res. Exped., 1929-1931, Ser. 

 B, Vol. 5, Pt. 6, 1950, p. 337) to V. rotundata Hofker (Siboga Exped., Foraminifera Pt. 3, 1951, p. 304, 305) 

 figures specimens rather close to Brady's figures as Cassidulinoides subsquamosa (Egger) but does not refer to 

 Cushman (1. c. supra, 1937) or to Parr. 

 Figures 12, 13. — Pleurostomellina (?) sp. nov. 



Fig. 12. Challenger Sta. 346, South Atlantic. (2350 fathoms) 

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

 Referred by Brady to Pleurostomella subnodosa Reuss, genotype of Pleurostomella from the U. Cretaceous 

 of Europe. The predominantly uniserial nature of the test suggests Pleurostomellina but the aperture appears 

 different. It appears to be a new species. 

 Figures 14-17. — Virgulina subdepressa Brady. 



Challenger Sta. 296, South Pacific. (1825 fathoms) 

 Figures 18-19. — Bolivina earlandi Parr. 



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

 Referred by Brady to B. punctata d'Orbigny. The figures show no sign of the carinate periphery of B. punc- 

 tata and probably represent B. earlandi Parr (B.A.N. Z. Antarctic Res. Exped., Ser. B, Vol. 5, No. 6, 1950, 

 p. 339). 

 Figures 20, 21. — Bolivina spathulata (Williamson). 



Porcupine Sta. 18, West of Ireland, E. Atlantic. (183 fathoms) 

 Referred to B. dilatata Reuss by Brady and to B. spathulata (Williamson) {Textularia variabilis Williamson 

 var. spathulata, 1858) by Cushman (C.L.F.R., Spec. Publ. No. 9, 1937, p. 162). 

 Figure 22. — Loxostomum porrectum (Brady). 



Challenger Sta. 24, West Indies. (390 fathoms)
