EXPLANATION OF PLATE 75 (LXXV), CONTINUED 



Figures 25-26. — Siphogenerina striata (Schwager) var. curta Cushman. 

 Fig. 25. Challenger Sta. 192, Ki Islands, Pacific. (129 fathoms) 

 Fig. 26. Challenger Sta. 209, Philippines. (95-100 fathoms) 

 Referred by Brady to Sagrina striata (Schwager) and by Cushman (Proc. U.S.N.M., Vol. 67, Art. 25, 1926, 

 p. 8) to Siphogenerina striata var. curta. 



EXPLANATION OF PLATE 76 (LXXVI) 



Figs. 1-3, 20, X 60; Figs. 4-7, 11-16, X 70; Figs. 8-10, X 50-70; Figs. 17, 18, X 75; 

 Fig. 19, X 150; Fig. 21, X 100; Figs. 22-28, X 35. 

 Figures 1-3. — Rectobolivina dimorpha (Parker and Jones) var. pacifica Cushman. 

 Fig. 1. Challenger Sta. 191A, Ki Islands, Pacific. (580 fathoms) 

 Figs. 2, 3. Challenger Sta. 279A, off Tahiti, Pacific. (420 fathoms) 

 Referred by Brady to Sagrina dimorpha (P. & J.) and by Cushman (Proc. U.S.N.M., Vol. 67, Art. 25, 1926, 

 p. 13) to Siphogenerina dimorpha var. pacifica. Hofker (Siboga Exped., Foraminifera Pt. Ill, 1951, p. 116) 

 shows dimorpha to be biserial, then uniserial, and therefore a Rectobolivina, and it is assumed that the var. 

 pacifica should also be placed in that genus. 

 Figures 4-7. — Rectobolivina (?) virgula (Brady). 



Fig. 4. Challenger Sta. 195A, off Amboyna, Pacific. (15-20 fathoms) 

 Figs. 5-7. Challenger Sta. 217A, off Papua, Pacific. (37 fathoms) 

 Referred by Brady to Sagrina and by Egger and Cushman to Siphogenerina. Hofker (Siboga Exped., Fora- 

 minifera Pt. Ill, 1951, p. 93) refers forms regarded as virgula to Rectobolivina, but as his figures show consider- 

 able differences from those of Brady there is doubt that he was dealing with the same species, and if not, there 

 is a possibility that the true virgula is a Siphogenerina. 

 Figure 8. — Stilostomella bradyi (Cushman). 



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

 Referred by Brady to Sagrina virgula Brady and by Cushman (C.C.L.F.R., Vol. II, 1927, p. 79) to Nodo- 

 generina bradyi, as the genotype of Nodogenerina. Finlay (N.Z. Jour. Sci. and Techn., Vol. 28, No. 5, 1927, 

 p. 273) has shown that Nodogenerina is a synonym of Stilostomella Guppy. 

 Figures 9, 10. — Stilostomella antillea (Cushman). 



No locality given but this species was referred to the Atlantic by Cushman. 

 Referred by Brady to Sagrina virgula Brady and by Cushman (U.S.N. M. Bull. 104, Pt. 4, 1923, p. 91) to 

 Nodosaria antillea. Referred to Nodogenerina by Church (Jour. Pal., Vol. 1, 1928, p. 267) and to Siphonodosaria, 

 regarded as the prior name to Nodogenerina, by Stainforth (Contr. Cush. Found. Foram. Res., Vol. 3, Pt. 

 1, 1952, p. 11). As noted above Stilostomella is regarded as the correct generic name for these forms. 

 Figures 11-16. — Nubeculina divaricata (Brady). 



Figs. 11-15. Challenger Sta. 21 7A, off Papua, Pacific. (37 fathoms) 

 Fig. 16. Challenger Sta. 172, Friendly Islands, Pacific. (18 fathoms) 

 Referred by Brady to Nubecularia and by Cushman (Carnegie Inst. Washington Publ. 342, 1924, p. 52) 

 to Nubeculina as genotype. 

 Figures 17-19. — Schubertia tessellata (Brady). 



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

 Referred by Brady to Sagrina (?) and to Mtllettia Schubert (non Duncan) by Schubert. Renamed Schubertia 

 by Silvestri (Riv. Ital. Pal., Vol. 18, 1912, p. 68), as type species. Fig. 17 designated lectotype of 5. tessellata 

 by Loeblich and Tappan (Smiths. Misc. Coll., Vol. 128, No. 5, 1955, p. 24). 

 Figures 20, 21. — Siphogenerina (?) annulata (Brady). 



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

 Referred by Brady to Sagrina (?) and by Cushman (U.S.N. M. Bull 71, Pt. 3, 1913, p. 109) to Siphogenerina 

 (?). This appears to be a new genus. 

 Figures 22-28. — Ramulina globulifera Brady. 



Figs. 22-24, 27. Challenger Sta. 174C, off Fiji, Pacific. (210 fathoms) 

 Figs. 26. Challenger Sta. 23, West Indies. (450 fathoms)
