EXPLANATION OF PLATE 40 (XL) 



Figs. 1-3, X 25; Figs. 4-7, 10-12, X 20; Figs. 8, 9, 13, 14, X 30; Fig. 15, X 50; Fig. 16, X 60; 

 Fig. 17, X 45; Fig. 18, X 30; Figs. 19-23, X 50. 

 Figures 1-3. — Trochamminoides proteus (Karrer). 



Figs. 1, 2. Challenger Sta. 120, off Pernambuco, Atlantic. (675 fathoms) 

 Fig. 3. Challenger Sta. 24, West Indies. (390 fathoms) 

 Referred to Trochammina by Brady; made the genotype of Trochamminoides by Cushman, 1910 (U.S.N.M. 

 Bull. 71, Pt. 1, p. 97). 

 Figures 4-7. — Lituotuba lituiformis (Brady). 



Fig. 4. Challenger Sta. 76, off the Azores, Atlantic. (900 fathoms) 

 Figs. 5, 6. Challenger Sta. 120, off Pernambuco, Atlantic. (675 fathoms) 

 Fig. 7. Challenger Sta. 24, West Indies. (390 fathoms) 

 Placed in Trochammina by Brady; the genotype of Lituotuba Rhumbler 1895 (Nachr. Kongl. Ges. Wiss. 

 Gottingen, p. 83). 

 Figures 8, 9. — Trochammina conglobata Brady. 



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

 Figures 10-12. — Haplophragmoides coronatum (Brady). 



Fig. 10. Challenger Sta. 23, West Indies. (450 fathoms) 

 Fig. 11. Challenger Sta. 120, off Pernambuco, Atlantic. (675 fathoms) 

 Fig. 12. Challenger Sta. 24, West Indies. (390 fathoms) 

 Referred by Brady to Trochammina; placed in Haplophragmoides by Cushman, 1910 (U.S.N.M. Bull. 71, 

 Pt. 1, p. 99). 

 Figure 13. — Cyclammina trullissata (Brady). 



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

 Referred by Brady to Trochammina trullissata Brady and by Cushman to Cyclammina bradyi (U.S.N.M. 

 Bull. 71, Pt. 1, 1910, p. 113). Parker (Bull. Mus. Comp. Zool., Harvard, Vol. 106, No. 9, 1952, p. 400) has 

 pointed out that Brady's original figures lOa-b of T. trullissata (Jour. Roy. Micr. Soc, 1879, pi. 5) are identical 

 with the present figures 13a-b, therefore the name trullissata must be retained for this form. 

 Figures 14, 15. — Alveolophragmium wiesneri (Parr). 



Challenger Sta. 323, South Atlantic. (1900 fathoms) 

 Referred by Brady to Trochammina trullissata and by Cushman to Haplophragmoides trullissata. Parker, 

 1. c. supra, named this form Labrospira arctica but Brady's figures had already been referred to Labrospira 

 wiesneri by Parr, 1950 (B.A.N.Z. Antarctic Res. Exped., Foraminifera, p. 272) who also reaches the con- 

 clusion that Fig. 13 is Cyclammina trullissata (Brady). Loeblich and Tappan, as already noted, have shown 

 that Labrospira Hoglund is a synonym of Alveolophragmium Tschedrina 1936. 

 Figure 16. — NOT IDENTIFIED (inner surface of the test of "Trochammina trullissata"). 

 Figures 17, 18. — Alveolophragmium ringens (Brady). 



Fig. 17. Challenger Sta. 323, South Atlantic. (1900 fathoms) 

 Fig. 18a. Challenger Sta. 98, W. coast of Africa. (1750 fathoms) 

 Fig. 18b. Challenger Sta. 70, N. Atlantic. (1675 fathoms) 

 Referred by Brady to Trochammina and by Eimer and Fickert (Zeitschr. Wiss. Zool., 1899, Vol. 65, p. 692) 

 to Ammochilostoma. Parker (Bull. Mus. Comp. Zool. Harvard, Vol. Ill, No. 10, 1954, p. 487) has transferred 

 it to Alveolophragmium. 

 Figures 19-23. — Cystammina galeata (Brady). 



Figs. 19, 20, 23. Challenger Sta. 346, South Atlantic. (2350 fathoms) 

 Figs. 21, 22. Challenger Sta. 332, South Atlantic. (2200 fathoms) 

 Referred by Brady to Trochammina and by Eimer and Fickert to their new genus Ammochilostoma (1. c. 

 supra, 1899). Galloway, Manual of the Foraminifera, 1933, p. 186, points out that Ammochilostoma is a synonym 

 of Cystammina Neumayr 1889, genotype Trochammina pauciloculata Brady, designated by Galloway and also 

 by Cushman, 1933.
