 Brady regarded Proteonina Williamson 1858 as in part synonymous with Reophax Montfort 1808, and 

 included P. fusiformis Williamson, later made the type of Proteonina (see below), in that genus. Proteonina 

 was retained by Rhumbler, Cushman, Galloway, and most recent workers but is now placed in the synonymy 

 of Reophax by Loeblich and Tappan (Smiths. Misc. Coll., Vol. 128, No. 5, 1955, p. 7). Millett (Jour. Roy.Micr. 

 Soc, 1899, p. 253) referred figs. 1 and 5 (below) to Proteonina difflugiformis var. lagenarium (Berthelin), and 

 has been followed in this by Rhumbler, Cushman and Thalmann. Earland (Discovery Repts., Vol. 10, 1934, 

 Foraminifera III, p. 64) has disputed this and refers figs. 1-5 to difflugiformis. More recently F. L. Parker (Bull. 

 Mus. Comp. Zool., Harvard, Vol. 106, No. 9, 1952, p. 393) has referred fig. 1 to difflugiformis, with no reference 

 to var. lagenarium and has separated fig. 5 as Proteonina atlantica Cushman; these opinions are followed here. 

 Figure 5. — Reophax atlantica (Cushman). 



Porcupine Sta. 47, Faroe Channel, North Atlantic. (542 fathoms) 

 Referred by Brady to R. difflugiformis and by Millett (1. c. supra, 1899), Rhumbler, Cushman and others 

 to Proteonina difflugiformis var. lagenarium (Berthelin). Cushman described Proteonina atlantica (C.L.F.R. 

 Spec. Publ. No. 12, 1944, p. 5) from shallow water ofif the New England coast, and F. L. Parker (1. c. supra, 

 1952, p. 393) referred Brady's fig. 5 to this species, although Cushman had made no reference to Brady. Parker 

 is followed here. 

 Figure 6. — Reophax ampullacea Brady. 



Challenger Sta. 1491, Kerguelen Is., South Pacific. (120 fathoms) 

 Referred to Proteonina Williamson by Rhumbler (Arch. Protist., Vol. 3, 1903 (1904), p. 248) and authors. 

 See note above on synonymy of Proteonina with Reophax. 

 Figures 7-11. — Reophax fusiformis (Williamson). 

 Figs. 7, 8. Loch Fyne, Scotland, N. Atlantic. 

 Figs. 9, 10. Cumbrae, Scotland, N. Atlantic. 

 Fig. 11. Philippine Islands, Pacific. 

 This was originally described as Proteonina and was designated the type of that genus by Rhumbler (Arch. 

 Protist., Vol. 3, 1903 (1904), p. 244). As noted above this is now regarded as a synonym of Reophax. 

 Figures 12, 14-17. — Reophax scorpiurus Montfort. 



Fig. 12. Off the Hebrides, W. Scotland, N. Atlantic. 

 Fig. 14. Challenger Sta. 323, S. Atlantic. (1900 fathoms) 

 Fig. 15. Challenger Sta. 260A, Honolulu reefs, Pacific. (40 fathoms) 

 Figs. 16-17. Challenger Sta. 185, Torres Strait, Pacific. (155 fathoms) 

 Figure 13. Reophax agglutinatus Cushman. 



Referred by Brady to R. scorpiurus Montfort. Cushman, 1913, U.S.N.M. Proc, Vol. 44, p. 637, pi. 79, 

 fig. 6, referred this figure to Reophax agglutinatus. Earland, 1934, (Discovery Reports, Vol. X, Foraminifera 

 Part III, p. 79) suggests that it is at most a variety of R. scorpiurus, and is the same as R. scorpiurus var. 

 testacea Wiesner, 1931, Foram. Deutsche Siidpolar Exped., p. 89, pi. 8 fig. 100, pi. 9 fig. 101, Wiesner referring 

 Brady's figs. 13 and 16 to this variety. 

 Figures 18-20. Reophax pilulifer Brady. 



Fig. 18. Porcupine Sta. 31, North Atlantic. (?) 

 Figures 21-22. — Rheophax dentaliniformis Brady. 



Fig. 21. Challenger Sta. 300, N. of Juan Fernandez, E. Pacific. (1375 fathoms) 

 Fig. 22. Porcupine Sta. 23, N.W. of Ireland, N. Atlantic. (630 fathoms) 

 Thalmann, 1932 (Eclog. geol. Helvet., Vol. 25, No. 2, p. 299), refers these two figures to R. scorpiurus 

 Montfort. This is not in accord with other workers, insofar as the writer can ascertain, and as no grounds 

 for this are given, Brady's name has been retained. 

 Figures 23, 24. — Reophax bacillaris Brady. 

 Valorous Sta. 8. North Atlantic.
