EXPLANATION OF PLATE 8 (VIII) 



Figs. 1-7, X 50; Figs. 8-10, X 30; Figs. 11, 14, X 50; Fig. 13, X 18; Fig. 12, X 30; 

 Figs. 15-17, X 25; Fig. 18, X 40; Figs. 19, 20, X 25. 

 Figures 1-4. — Sigmoilopsis schlumbergeri (Silvestri). 



Figs. 1, 2. Porcupine Sta. 23, W. of Ireland, Atlantic. (630 fathoms) 

 Fig. 3. Challenger Sta. 120, off Pernambuco, Atlantic. (675 fathoms) 

 Fig. 4. Porcupine Sta. 37, off Ireland, Atlantic. (2435 fathoms) 

 Referred to Planispirina celata (Costa) by Brady and to Sigmoilina schlumbergeri by Silvestri (Mem. Pont. 

 Nuovi Lincei, Vol. 22, 1904, p. 267). Finlay (N.Z. Jour. Sci. Techn., Sec. B, Vol. 28, 1947, p. 270) erected the 

 genus Sigmoilopsis with 5. schlumbergeri (Silvestri) as the genotype. 

 Figure 5. — Flintina crassatina (Brady). 



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

 Referred by Brady to Miliolina and to Flintina by Thalmann (Eclog. geol. Helv., Vol. 25, No. 2, 1932, 

 p. 297). 

 Figures 6, 7. — Dentostomina agglutinans (d'Orbigny)? 



Fig. 6. Challenger Sta. 218A, Admiralty Islands, Pacific. (16-25 fathoms) 

 Fig. 7. Porcupine Sta. 37, off Ireland, Atlantic. (2435 fathoms) 

 Referred by Brady to Miliolina and by d'Orbigny, Cushman and others to Quinqueloculina. The Cuban 

 species of d'Orbigny shows a serrate aperture and was placed by Bermudez (Mem. Soc. Cub. Hist. Nat., Vol. 

 9, No. 3, 1935, p. 161) in Dentostomina. Brady's figures differ considerably from those of d'Orbigny and may 

 represent a new species of Quinqueloculina. 

 Figures 8-10. — Flintina triquetra (Brady). 



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

 Referred by Brady to MtUolina and transferred by Cushman (U.S.N. M., Bull. 100, Vol. 4, 1921, p. 466) 

 to Flintina. 

 Figures 11?, 13, 14. — Ammomassilina alveoliniformis (Millett)? 



Fig. 11. Porcupine Sta. 47, Faroe Channel, N. Atlantic. (542 fathoms) 

 Fig. 13. Challenger Sta. 218A, Admiralty Islands, Pacific. (16-25 fathoms) 

 Fig. 14. Challenger Sta. 217A, off Papua, Pacific. (37 fathoms) 

 Referred by Brady to Spiroloculina asperula Karrer and by Cushman (U.S.N.M., Bull. 100, Vol. 4, 1921, 

 p. 447) to Massilina asperula (Karrer). A study of original figures suggests that there may be three species 

 here, Praemassilina sp. (fig. 11) Praemassilina asperula (Karrer, fig. 14) (see Lacroix, Bull. I'lnst. Oceanogr. 

 Monaco, No. 754, 1938, p. 3) and Ammomassilina alveoliniformis (Millett) (fig. 13). Cushman (U.S.N.M., 

 Bull. 104, Pt. 6, 1929, p. 39) referred all three figures to Massilina alveoliniformis Millett and later (C.C.L.F.R., 

 Vol. 9, Pt. 2, 1933, p. 32) made alveoliniformis Millett the genotype of Ammomassilina without further reference 

 to Brady's figures. 

 Figure 12. — Praemassilina arenaria (Brady). 



Challenger Sta. 174C, off Fiji, Pacific. (210 fathoms) 

 Referred by Brady to Spiroloculina and by Lacroix (Bull. I'lnst. Oceanogr. Monaco, No. 754, 1938, p. 3) 

 to Praemassilina arenaria (Brady). 

 Figures 15-20. — Schlumbergerina alveoliniformis (Brady). 



Figs. 15, 16. Challenger Sta. 218A, Admiralty Islands, Pacific. (16-25 fathoms) 

 Fig. 17. Challenger Sta. 260A, off Honolulu, Pacific. (40 fathoms) 

 Fig. 18-20. Tongatabu, Pacific. (18 feet) 

 Referred by Brady to Miliolina and by Cushman first to Quinqueloculina and later (U.S.N.M., Bull. 104, 

 Pt. 6, 1929, p. 36) to Schlumbergerina.
