EXPLANATION OF PLATE 50 (L) 



Figs. 1, 5, 6, 11, 12, X 60; Figs. 2-4, 8-10, 13, 14, X 50; Fig. 7, X 40; Fig. 15, X 45; 

 Figs. 16, 18, 20-24, X 80; Fig. 17, X 60; Fig. 19, X 70. 

 Figures 1-4. — Bulimina gibba Fornasini. 



Figs. 1, 2. Porcupine Sta. 11, West of Ireland, Atlantic. (1630 fathoms) 

 Figs. 3, 4. Porcupine Sta. 10, West of Ireland, Atlantic. 

 Referred by Brady to B. elegans d'Orbigny. Cushman and Parker, in 1940 (C.C.L.F.R., Vol. 16, Pt. 1, p. 

 14), placed B. fusiformis Fornasini, B. elegans of Brady, non d'Orbigny, B. fustformis var. baccata Fornasini 

 and B. gibba Fornasini in the synonymy of B. baccata Fornasini. Thalmann (Amer. Midland Nat., Vol. 28, 

 1942, p. 464) pointed out that the name baccata was preoccupied by Yokoyama 1890, and proposed the name 

 B. parkeri for these figures. B. parkeri however had already been used by Terquem and Terquem 1886, so Cush- 

 man and Parker (U.S.G.S. Prof. Paper 210-D, 1947, p. 125) have proposed reverting to the earliest valid name, 

 B. gibba Fornasini. Fornasini (Mem. R. Ace. Sci. 1st. Bologna, Ser. V, Vol. 9, 1901, p. 377) referred figures 3, 

 4 of Brady to Bulimina fusiformis Williamson (megalospheric form) but since this species is now regarded as 

 a Virgulina his views are not followed. 

 Figures 5, 6. — Bulimina exilis Brady. 



Procupine Sta. 20, N.W. of Ireland, N. Atlantic. (1443 fathoms) 

 Referred by Brady to B. elegans var. exilis nov. 

 Figures 7-10. — Globobulimina pacifica Cushman? 



Figs. 7, 8. Challenger Sta. 75, off the Azores, Atlantic. (450 fathoms) 

 Fig. 9. Challenger Sta. 168, off New Zealand. (1100 fathoms) 

 Fig. 10. Challenger Sta. 192, Ki Islands, C. Pacific. (129 fathoms) 

 Referred by Brady to Bulimina pyrula d'Orbigny and by Galloway and Wissler (Jour. Pal., Vol. 1, 1927, 

 p. 74) to Globobulimina pacifica Cushman. Parr (B.A.N.Z. Antarctic Res. Exped., 1929-1931, Ser. B, Vol. 5, 

 No. 6, 1950, p. 337) also gives this determination. Cushman and Parker (U.S.G.S. Prof. Paper 210-D, 1947, 

 p. 134) refer these figures doubtfully to G. glabra Cushman and Parker, an Italian Pliocene species. This iden- 

 tification is questioned, but, as pointed out by Cushman and Parker, Brady's figures may represent more than 

 one species. 

 Figures 11, 12. — Bulimina pyrula d'Orbigny var. spinescens Brady. 

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

 Hofker (Siboga Exped., Foraminifera Pt. Ill, 1951, p. 249) makes this the genotype of Praeglobobulimina, 

 and should this genus prove to be valid that name will stand, as Praeglobobulimina spinescens (Brady). 

 Figure 13. — Bulimina notovata Chapman. 



Challenger Sta. 168, East of New Zealand. (1100 fathoms) 

 Referred by Brady to B. ovata d'Orbigny. Galloway and Heminway (N.Y. Acad. Sci., Sci. Surv. Porto Rico, 

 Vol. 3, No. 4, 1941, p. 423) refer Brady's figures to Bulimina socialis Bornemann, but preference is given here 

 to Chapman's B. notovata (Trans. Roy. Soc. South Australia, Vol. 65, 1941, p. 166). 

 Figure 14. — Bulimina pupoides d'Orbigny? 



Challenger Sta. 306, West of Patagonia, E. Pacific (345 fathoms) 

 Referred by Brady to B. affinis d'Orbigny but regarded as probably B. pupoides (microspheric form) by 

 Cushman and Parker (U.S.G.S. Prof. Paper 210-D, 1947, p. 105). If correct it should perhaps be termed Pro- 

 toglobobulimina pupoides (d'Orbigny) (Hofker, Siboga Exped., Foraminifera Pt. Ill, 1951, p. 254). 

 Figure 15. — Bulimina pupoides d'Orbigny. 



Challenger Sta. 306, West of Patagonia, E. Pacific. (345 fathoms) 

 Hofker (Siboga Exped., Foraminifera Part HI, 1951, p. 254) places this species in Proto globobulimina, and 

 should the validity of this genus be established that name will stand. 

 Figure 16. — Robertina subcylindrica (Brady). 



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

 Referred by Brady to Bulimina and transferred to Robertina by Cushman and Parker (C.C.L.F.R., Vol. 12, 

 1936, p. 95). 

 Fig. 17. — Robertina tasmanica Parr? 



Challenger Sta. 174B, Fiji, Pacific. (610 fathoms) 

 Referred by Brady to Bulimina subteres Brady 1881. Cushman and Parker (U.S.G.S. Prof. Paper 210 D, 

 1947, p. 76) have pointed out that neither of Brady's figs. 17 or 18 of the present plate are the same as the 

 Bulimina subteres originally described in 1881, which is a North Atlantic species. Parr (B.A.N.Z. Antarctic 

 Res. Exped. 1929-1931, Reports, Ser. B, Vol. 5, 1950, Pt. 6, p. 369) notes that his R. tasmanica may be the same 

 as the present fig. 17 of 5. subteres. 

 Figure 18. Robertinoides bradyi Cushman and Parker.* 

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

 Referred by Brady to Bulimina subteres Brady 1881 (see above) and by Cushman and Parker (C.C.L.F.R., 

 Vol. 12, 1936, p. 99) to Robertina bradyi. 



*NoTE: J. Hofker (Spolia Zool. Mus. Hauniensis, Vol. 15, 1956, p. 128) has placed Robertina bradyi Cushman and Parker in Robertinoides 

 Hoglund 1947. Though he does not refer to Brady's figure his conclusion was based on a careful study of West Indian material and is 

 regarded as correct.
