 Figure 1. — Vertehralina sp. juv. 



Challenger Sta. 174A, off Fiji, Pacific. (255 fathoms) 

 Referred by Brady to "Miliolina sp., or possibly an early stage of Articulina." 

 Figures 2, 3. — Quinqueloculina pseudoreticulata Parr. 



Challenger Sta. 188, S. of New Guinea, Pacific. (28 fathoms) 

 Referred by Brady to Miliolina reticulata (d'Orbigny) and by Parr (Mining and Geol. Jour., Melbourne, 

 Vol. 2, 1941, p. 305) to Quinqueloculina pseudoreticulata. 

 Figure 4. — Quinqueloculina reticulata d'Orbigny. 



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

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

 Figures 5, 6. — Spiroloculina communis Cushman and Todd. 



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

 Referred by Brady to 5. excavata d'Orbigny, and by Earland (MS) to 5. limbata d'Orbigny. Cushman 

 (U.S.N.M., Bull. 104, Pt. 6, 1929, p. 40) referred these figures to 5. grateloupi d'Orbigny and Cushman and 

 Todd (C.L.F.R., Spec. Publ. No. 11, 1944, p. 63) to S. communis. 

 Figures 7, 8. — Flintia robusta (Brady). 



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

 Referred by Brady to Spiroloculina and by Schubert (Abhandl. k. k. Geol. Reichs., Vol. 20, 1911, p. 124) 

 to Flintia, as genotype. 

 Figures 9, 10. — Massilina milletti (Wiesner). 



Fig. 9. Challenger Sta. 233B, off Japan, Pacific. (15 fathoms) 

 Fig. 10. Challenger Sta. 187A, Torres Strait, Pacific. (8 fathoms) 

 Referred by Brady to Spiroloculina nitida d'Orbigny and by Wiesner (Archiv f. Protist., Vol. 25, 1912, p. 

 207) to 5. milletti. Transferred to Massilina by Cushman and Todd in 1944 (C.L.F.R., Spec. Publ. No. 11, 

 p. 76). 

 Figure 11. — Spiroloculina henbesti Petri. 



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

 Referred by Brady to 5. planulata (Lamarck), an Eocene species, the type of which, according to Cushman 

 and Todd (C.L.F.R., Spec. Publ. No. 11, 1944, p. 76) is a Quinqueloculina. Referred to Spiroloculina concava 

 by Petri (Univ. Sao Paulo, Brazil, Fac. Filos. Cienc. Let., Bull. No. 176 (Geol. No. 11), 1944, p. 53, pi. ii, 

 figs. 3-6), preoccupied by S. acutimargo Brady var. concava Wiesner 1916. Renamed S. henbesti (see Thalmann, 

 Contr. Cushman Found. For. Res., Vol. 6, No. 2, 1955, p. 82). 

 Figures 12-14. — Hauerina fragilissima (Brady). 



Figs. 12, 13. Challenger Sta. 279C, off Tahiti, Pacific. (620 fathoms) 

 Fig. 14. Challenger Sta. 218A, Admiralty Islands, Pacific. (16-25 fathoms) 

 Referred by Brady to Spiroloculina and by Millett (Jour. Roy. Micr. Soc, 1898, p. 610) to Hauerina. 

 Figures 15, 16. — Spiroloculina rotunda d'Orbigny? 



Challenger Sta. 344, Ascension Island, S. Atlantic. (420 fathoms) 

 Referred by Brady to S. limbata d'Orbigny and by Earland (MS) to 5. excavata d'Orbigny. It appears to be 

 most similar to 5. rotunda d'Orbigny, but should also be compared with S. soldanii Fornasini. 

 Figure 17. — Spiroloculina depressa d'Orbigny? 



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

 Referred by Brady to S. limbata d'Orbigny and reproduced as 5. depressa d'Orbigny by Cushman (U.S.N.M., 

 Bull. 104, Pt. 6, 1929, pi. ix, fig. 8). It does not appear to be very similar to d'Orbigny's model or later figures, 

 except that copied by Fornasini from the "Planches inedites." It is closely related to S. soldanii Fornasini and 

 5. rotunda d'Orbigny.
