EXPLANATION OF PLATE 50 (L), CONTINUED 



Figure 19. — Robertina oceanica Cushman and Parker. 



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

 Referred by Brady to Bulimina declivis Reuss and by Cushman and Parker (U.S.G.S. Prof. Paper 210-D, 

 1947, p. 75) to Robertina oceanica. 

 Figures 20-22. — Buliminella elegantissima (d'Orbigny). 



Challenger Sta. 315A, Falkland Islands, S. Atlantic. (6 fathoms) 

 Referred by Brady to Bulimina and transferred to Buliminella by Cushman in 1911 (U.S.N.M. Bull. 71, 

 Ft. 2, p. 89). 

 Figures 23, 24. — Buliminella basicostata Parr. 



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

 Referred by Brady to Bulimina elegantissima var. seminuda Terquem and to Buliminella basicostata by Parr 

 (B.A.N.Z. Anarctic Research Exped., 1929-1931, Vol. 5, Pt. 6, 1950, p. 336). Cushman and Parker (U.S.G.S. 

 Prof. Paper 210-D, 1947, p. 61) refers fig. 23 tentatively to Bulminella madagascariensis (d'Orbigny) and fig. 

 24, also tentatively to Buliminella semi-nuda (Terquem)? 



EXPLANATION OF PLATE 51 (LI) 



Fig. 1, X 70; Figs. 2-6, 14-19, X 80; Figs. 7-13, 21, 23, X 60; Fig. 20, X 40; Fig. 22, X 70. 

 Figures 1, 2. — Bulimina elongata d'Orbigny var. subulata Cushman and Parker. 

 Porcupine Sta. 23, N.W. of Ireland, N. Atlantic. (630 fathoms) 

 Brady referred fig. 1 to B. elongata d'Orbigny and fig. 2 to an intermediate form between elongata and B. 

 ovata d'Orbigny. Fornasini (Mem. R. Ace. Sci. 1st. Bologna, Ser. V, Vol. 9, p. 377) put these figures in synonymy 

 with B. elongata var. ariminensis d'Orbigny. Clodius next referred them to B. elongata var. cuspidata (Ver. 

 Freunde Naturg. Mecklenburg, Arch., Jahrg. 75, 1922, p. 101) from the U. Miocene of Germany. Cushman 

 (U.S.N.M. Bull. 161, Pt. 3, 1942, p. 11) regards figs. 1, 2 as B. elongata var. subulata Cushman and Parker 

 1937, from the Miocene of the Vienna Basin. Since varietal names must be regarded as homonyms (see Thal- 

 mann, Amer. Midland Nat., Vol. 28, 1942, p. 459) then B. elongata var. cuspidata Clodius 1922 becomes a 

 homonym of B. cuspidata Franzenau 1894 and the correct name is B. elongata var. subulata Cushman and 

 Parker. 

 Figures 3-5. — Bulimina marginata d'Orbigny. 



Porcupine Sta. 11, West of Ireland, N. Atlantic. (1630 fathoms) 

 Figure 6. — Bulimina subornata Brady. 



Challenger Sta. 232, South of Japan, N. Pacific. (345 fathoms) 

 Figures 7-9. — Bulimina aculeata d'Orbigny. 



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

 Figures 10, 12. — Bulimina striata d'Orbigny var. mexicana Cushman? 

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

 Referred by Brady to B. inflata Seguenza. Cushman and Parker (U.S.G.S. Prof. Paper 210-D, 1947, p. 119) 

 note that Brady's figs. 10-13 represent a form similar to B. striata var. mexicana but distinguished by some- 

 what less sharp spines (see also note below). 

 Figures 11, 13. — Bulimina costata d'Orbigny? 



Fig. 11. Challenger Sta. 232, South of Japan, N. Pacific. (345 fathoms) 

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

 Referred by Brady to B. inflata Seguenza and to B. costata d'Orbigny by Cushman and Parker (U.S.G.S. 

 Prof. Paper 210-D, 1947, p. 115). There appear to be marked differences between these figures and those of 

 B. costata d'Orbigny and the identity is queried. Brady's form would appear to be more closely allied to B. 

 striata d'Orbigny. 

 Figures 14, 15. — Bulimina rostrata Brady. 



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

 Figures 16, 17. — Bulimmoides williamsonianus (Brady). 



Fig. 16. Challenger Sta. 219A, Admiralty Islands, Pacific. (17 fathoms) 

 Fig. 17. Challenger Sta. 185, Torres Strait, Pacific. (155 fathoms) 

 Referred by Brady to Bulimina and made the type of Buliminoides by Cushman (U.S.N.M. Bull. 71, Pt. 

 2, 1911, p. 90). 

 Figures 18, 19. — Bulimina sp. nov. 



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

 Referred to B. buchiana d'Orbigny by Brady. This species differs from B. buchiana in possessing fewer costae 

 which are continuous over the sutures, and appears to be new.
