EXPLANATION OF PLATE 105 (CV) 



Figs. 1, 4-7, X 35; Figs. 2, 8, 9, X 50; Fig. 3, X 40. 

 Figure 1. — Mississippina concentrica (Parker and Jones). 

 Off the Shetlands, N. Atlantic. (70-90 fathoms) 

 Referred by Brady to Pulvinulina. Parr (B.A.N.Z. Antarctic Res. Exped., 1929-1931, Ser. B, Vol. 5, Pt. 

 6, 1950, p. 360) places this form in Stomatorbina Dorreen and this procedure is followed by Phleger and Parker, 

 1951. Uchio (Trans. Proc. Pal. Soc. Japan, n.s., No. 7, 1952, pp. 195-200) has discussed the genera Stoma- 

 torbina and Mississippina and concludes that concentrica (P. & J.) is a true Mississippina and that Stoma- 

 trobina may prove to be a synonym of that genus, though this depends upon the generic value of apertural 

 characters. 

 Figure 2. — Eponides umbonatus (Reuss). 



Challenger Sta. 308, W. coast of Patagonia, E. Pacific. (175 fathoms) 

 Referred by Brady to Pulvinulina and by Cole (Bull. Amer. Pal., Vol. 14, No. 53, 1928, p. 215 (15)) to Epon- 

 ides. Galloway and Morrey have referred this species to Rotalia and Hofker (Siboga Exped., Foraminifera 

 Pt. Ill, 1951, p. 403) has placed umbonatus in Gyroidina, and as noted earlier it is probable that most forms 

 referred to Eponides require a new generic name. Hofker suggests that the forms referred to umbonatus probably 

 comprise more than one species. Uchio (Assoc. Petr. Techn., Tokyo, Jour., Vol. 15, No. 4, 1950) included 

 Eponides umbonatus (Reuss) in his new genus P seudoeponides , characterized by supplementary dorsal and ven- 

 tral apertures. As such supplementary apertures cannot be found in any of the Recent material available re- 

 ferred to E. umbonatus it has been retained here in the problematic genus "Eponides'' (auct., non Montfort). 

 Figures 3-6. — Hoglundina elegans (d'Orbigny). 

 Fig. 3. Porcupine Sta.?, North Atlantic. 



Fig. 4. Challenger Sta. 135, Tristan d'Acunha, Atlantic. (100-150 fathoms) 

 Fig. 5. Challenger Sta. 24, West Indies. (390 fathoms) 

 Referred by Brady to Pulvinulina and by Martinotti (Boll. R. Ufficio geol. Ital., Vol. 51, 1926, p. 3) to Epis- 

 tomina. Brotzen (Sver. Geol. Unders., Vol. 42, No. 2, 1948, p. 92) differentiated Tertiary and Recent forms pre- 

 viously assigned to Epistomina from the Jurassic forms, and referred them to Hoglundina gen. nov., with E. 

 elegans as genotype. Galloway and Wissler (Jour. Pal., Vol. 1, 1927, p. 60) referred fig. 3 to E. bradyi, and figs. 

 4-6 to E. flintii, but this has not been accepted by later authors and Cushman (U.S.N.M. Bull. 104, Pt. 8, 

 p. 66) referred these species to the synonymy of E. elegans (d'Orbigny). 

 Figure 7. — "Eponides (?)" procera (Brady). 



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

 Referred by Brady to Pulvinulina and by Thalmann (Eclog. geol. Helv., Vol. 25, No. 2, 1932, p. 310) to 

 Discorbis. Hofker (Siboga Exped., Foraminifera Pt. Ill, 1951, p. 396) places this species in Alabamina, and 

 states that it shows the apertural characters of that genus. These were not observed in specimens examined 

 and it is doubted that this is a true Alabamina. 

 Figures 8, 9. — Buccella frigidg. (Cushman). 



Fig. 8. Challenger Sta. 313, Magellan Strait, Antarctic. (55 fathoms) 

 Fig. 9. N. Polar Exped., 1875-76, Cape Frazier, Lat. 79° 45' N. 

 Referred by Brady to Pulvinulina karsteni (Reuss) and by Cushman (Results of the Hudson Bay Exped., 

 1920, I — The Foraminifera, Contr. Canadian Biol. (1921), No. 9, p. 12) to Pulvinulina frigida , with reference 

 to P. karsteni Brady 1864, non Reuss, but not to the Challenger Report. Transferred to Eponides by Cush- 

 man in 1931 and to Buccella by Anderson (Jour. Washington Acad. Sci., Vol. 42, No. 5, 1952, p. 144). Heron- 

 Allen and Earland (Discovery Repts., Vol. 4, Foraminifera Pt. 1, 1932, p. 431) noted great variation in Antarctic 

 material and included frigida in the synonymy of karsteni, retaining the name given by Reuss.
