and rather fewer chambers than Brady's specimen. In any case it seems erroneous to place gaimardi in synonymy 

 with ammonoides, and Pacific material shows extreme variation in these open-coiled, flat thin forms, the series 

 clearly including the form figured by d'Orbigny as gaimardi and the various specimens figured b}^ Cushman 

 as O. bartschi and varieties. It is possible that figs. 6 and 8 and possibly others could be grouped in this series 

 but Brady's specimens should be studied before any definite conclusion can be reached. 

 Figures 14-16. — Heterostegina depressa d'Orbigny. 



Fig. 14. Challenger Sta. 219A, Admiralty Islands, Pacific. (17 fathoms) 

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

 Fig. 16. Challenger Sta. 172, Friendly Islands, Pacific. (18 fathoms) 

 Hofker (Siboga Exped., Foraminifera Pt. I, 1927, p. 70) has placed H. depressa in the synonymy of H. 

 suborbicularis d'Orbigny, and also includes H. curva Moebius and H. antillarum d'Orbigny under the same head- 

 ing. H. suborbicularis d'Orbigny 1826 was a nomen nudum and only validated in 1903 by Fornasini. Fornasini 

 (Boll. Soc. Geol. Ital., Vol. 22, fasc. 3, 1903, p. 396) has shown that the Planches inedites of d'Orbigny contained 

 three figures labelled suborbicularis, two of which he regards as H. depressa d'Orbigny 1826, and the third very 

 like H. curva Moebius 1880 (see below). It is therefore believed that Hofker, Cushman and others are in error 

 in making use of the name suborbicularis. 

 Figures 17, 18. — Heterostegina sp., juv. 



Challenger Sta. 218A, Adm.iralty Islands, Pacific. (16-25 fathoms) 

 Brady referred these specimens to H. depressa d'Orbigny and Thalmann (Eclog. geol. Helv., Vol. 25, No. 2, 

 1932, p. 311) to H. costata d'Orbigny, an Austrian Miocene species. It seems probable that Brady was correct 

 but his material should be re-examined. 

 Figures 19, 20. — Heterostegina cf. curva Moebius. 



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

 Fornasini (1. c. supra, 1903, p. 396) compares these figures to one of the three unpublished drawings of 

 d'Orbigny labelled H. suborbicularis d'Orbigny 1826. As noted above suborbicularis was a nomen nudum and is 

 probably a synonym of C. curva Moebius, thus supporting Brady's identification of these forms.

Challenger Sta. 205A, off Hong Kong, Pacific. (7 fathoms) 

 Figure 2. — Siphotextularia crispata (Brady). 



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

 Referred by Brady to Textularia and by Cushman, Todd and Post (U.S.G.S. Prof. Paper 260-H, 1954, p. 

 330) to Siphotextularia. 

 Figures 3-5. — Gaudryina (Siphogaudryina) transversaria (Brady). 

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

 Referred by Brady to Textularia and by Said (C.L.F.R., Spec. Publ. 26, 1949, p. 8) to Gaudryina {Sipho- 

 gaudryina ) . 

 Figure 6. — Pseudobulimina sp. nov. ? 



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

 Referred by Brady to Bulimina convoluta Williamson. Cushman (1922) transferred convuluta to Buliminella 

 and Glaessner (Stud. Micropal., Moscow, Vol. 1, Pt. 3, 1937, p. 23) placed it in Pseudobulimina Earland. 

 Makiyama and Hakagawa (Jour. Geol. Soc. Japan, Vol. 48, 1941, pp. 241, 243) referred convoluta to Gemino- 

 spira, and cited Brady's figures. Cushman and Parker (U.S.G.S. Prof. Paper 210-D, 1947, p. 77), apparently 

 in ignorance of the genus Geminospira retained convoluta in Pseudobulimina, but remarked that "the figures 

 given by Brady .... are probably not of a species identical with that of Williamson and perhaps do not belong 

 to Pseudobulimina." Loeblich and Tappan (personal communication) state that they have examined types 

 and regard Pseudobulimina and Geminospira as synonymous. 

 Figure 7. — Loxostoma strigosum (Brady). 



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

 Referred by Brady to Bolivina lobata var. strigosa, and by Cushman (C.L.F.R., Spec. Publ. No. 9, 1937, 

 p. 189) to Loxostoma strigosum (Brady). 

 Figure 8. — Cassidulina pacifica Cushman. 



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

 Referred by Brady to Cassidulina calabra (Seguenza) and by Cushman (C.C.L.F.R. Vol. 1, Pt. 3, 1925, 

 p. 24) to C. pacifica.
