EXPLANATION OF PLATE 34 (XXXIV) 



Figs. 1-4, X 20; Figs. 5, 6, X 50; Figs. 7, 8, X 20; Fig. 9, X 15; Fig. 10, no magnification; 

 Figs. 11-14, X 40; Figs. 15-18, X 100. 

 Figures 1-4. — Ammobaculites americanus Cushman. 



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

 Referred to Haplophragmium fontinense Terquem by Brady. Cushman, U.S.N.M. Bull. 71, Pt. 1, p. 117, 

 1910, described and figured specimens from the West Coast of Mexico, and referred to the present figures of 

 Brady. His figures appear to indicate the same species, or certainly one very closely similar. 

 Figures 5, 6. — Haplophragmoides rotulatum (Brady). 



Challenger Sta. 5, North Atlantic. (2740 fathoms) 

 Referred by Brady to Haplophragmium. 

 Figures 7, 8, 10, 14? — Alveolophragmium subglohosum (G.O. Sars). 



Fig. 7. Challenger Sta. 300, N. of Juan Fernandez. (1375 fathoms) 

 Fig. 8. Challenger Sta. 24, West Indies. (390 fathoms) 

 Fig. 10. Challenger Sta. 24, West Indies. (390 fathoms) 

 Fig. 14. Challenger Sta. 174C, Fiji. (210 fathoms) 

 Referred by Brady to Haplophragmium latidorsatum (Bornemann), Cushman referred the above figures to 

 Haplophragmoides subglobosum (G.O. Sars) in 1910 (U.S.N.M. Bull. 71, p. 105), separating Brady's fig. 9 

 (see below) as Cribrostomoides bradyi. Hoglund, 1947 (Zool. Bidrag. fr. Uppsala, Vol. 26, p. 144) placed sub- 

 globosum in his new genus Labrospira. Loeblich and Tappan (Smithson. Misc. Coll., Vol. 121, 1953, No. 7, 

 p. 9) have shown that Labrospira is a synonym of Alveolophragmium Tschedrina 1936, and are followed here. 

 Figure 9. — "Cribrostomoides bradyi Cushman." 



Challenger Sta. 246, North Pacific. (2050 fathoms) 

 Referred by Brady to Haplophragmium latidorsatum (Bornemann) (see above). Cushman (U.S.N.M. Bull. 

 71, Pt. 1, 1910, p. 108) erected a new genus, Cribrostomoides, with C. bradyi as genotype, referring to Brady's 

 figure 9, and basing the genus on multiple apertures. Earland (Discovery Reports, Vol. 10, Foraminifera — III, 

 1934, p. 89) states that these are an end development in large specimens of Haplophragmoides subglobosum 

 (Sars), and places C. bradyi Cushman in the synonymy of that species. He is followed by Hoglund (1947, see 

 above). Fig. 9 is therefore Alveolophragmium subglobosum (G.O. Sars). 

 Figures 11-13. — Alveolophragmium scitulum (Brady). 



Figs. 11, 12. Porcupine Sta. 47, Faroe Channel, N. Atlantic. (542 fathoms) 

 Fig. 13. Knight Errant Sta. 7, Faroe Channel, N. Atlantic. (530 fathoms) 

 Referred by Brady to Haplophragmium, by later authors to Haplophragmoides, and by Parker (Bull. Mus. 

 Comp. Zool., Harvard, Vol. Ill, No. 10, 1954, p. 487) to Alveolophragmium. 

 Figures 15-18. — Adercotryma glomeratum (Brady). 



Challenger Sta. 1491, Kerguelen Islands, S. Pacific. (120 fathoms) 

 Referred by Brady to Haplophragmium and by Cushman and later authors to Haplophragmoides. Loeblich 

 and Tappan (Jour. Washington Acad. Sci., Vol. 42, No. 5, 1952, p. 141) made it the genotype of their new 

 genus Adercotryma.
