EXPLANATION OF PLATE 109 (CIX) 



Figs. 1, 2, 20, 21, X 50; Figs. 3, 4, 6, 7, 10, 11, 14-19, 22, 23, X 75; 

 Fig. 5, X 60; Figs. 8, 9, 12, 13, X 70. 

 Figures 1, 2. — Astrononion fijiense Cushman and Edwards. 

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

 Referred by Brady to Nonionina asterizans (Fichtel and Moll) and by Cushman and Edwards (C.C.L.F.R., 

 Vol. 13, Pt. 1, 1937, p. 35) to Astrononion fijiense. 

 Figures 3, 4. — Astrononion stelligerum (d'Orbigny). 



Fig. 3. Porcupine Sta. 67-68, E. of Shetlands, N. Atlantic. (64-75 fathoms) 

 Referred by Brady to Nonionina stelligera d'Orbigny and by Cushman and Edwards, (1. c. supra, 1937, 

 p. 31) to Astrononion stelligerum (d'Orbigny). 

 Figure 5. — Astrononion tumidum Cushman and Edwards. 



Challenger Sta. 344, Ascension Island, Atlantic. (420 fathoms) 

 Referred by Brady to Nonionina stelligera d'Orbigny and by Cushman and Edwards (1. c. supra, 1939, p. 

 33) to Astrononion tumidum. 

 Figures 6, 7. — N onion depressulum (Walker and Jacob)? 



Challenger Sta. 163C, off Sydney, Australia. (6 fathoms) 

 Referred by Brady to Nonionina. Cushman (U.S.N.M. Bull. 104, Pt. 7, 1930, p. 3) stated "Brady's Chal- 

 lenger figures do not at all fit this form (i.e. N onion depressulum), but seem nearer to N . umbilicatulum." N. 

 umbilicatulum is a highly problematical species and Brady's figures agree fairly well with the figure and dis- 

 cussion of A^^. depressulum given by Macfadyen (Geol. Mag., Vol. 77, 1940, pp. 279-281). Brady's determina- 

 tion has therefore been retained pro tem. 

 Figures 8, 9. — Gavelinonion barleeanum (Williamson). 



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

 Fig. 9. Challenger Sta. 276, off Tahiti, Pacific. (2350 fathoms) 

 Referred by Brady to Nonionina umbilicatula (Montagu), though umbilicatula should be referred to Walker 

 and Jacob 1798 rather than to Montagu 1803. Cushman (U.S.N.M. Bull. 104, Pt. 7, 1930, p. 2) has pointed out 

 that umbilicatulum is virtually indeterminate from the original figures and description, and was referred by 

 Williamson to Polystomella and by Parker and Jones to Truncatulina. The West Indian form figured by Brady 

 is the same as that found off the British Isles (from material studied), and is regarded as barleeanum (William- 

 son). Cushman (1. c. supra, 1930, p. 11) says of barleeanum "recorded from about the British Isles as Nonionina 

 umbilicatula" and refers the species to Nonion. Hofker (Spolia Zool. Mus. Hauniensis, Copenhagen, Vol. 15, 

 1956, pp. 116, 118) retains the specific name umbilicatula, but notes that this form differs from true Nonion in 

 possessing thick walls, double septal walls and coarse pores and should be referred to Gavelinonion Hofker 1951. 

 He does not refer to Brady but from material examined and his description is thought to be dealing with the 

 present species, though his figures show considerable differences. Figure 9 appears somewhat different from the 

 Atlantic form of barleeanum and may represent a deep water variant or a subspecies.* 

 Figures 10, 11. — Nonion (?) pompilioides (Fichtel and Moll). 



Fig. 10. Porcupine Sta. 20, W. of Ireland, E. Atlantic. (1443 fathoms) 

 Referred by Brady to Nonionina. This is probably also a Gavelinonion. 

 Figures 12, 13. — Nonion cf. asterizans (Fichtel and Moll). 



Challenger Sta. 354A, Vigo Bay, E. Atlantic. (11 fathoms) 

 Referred by Brady to Nonionina boueana d'Orbigny. Cushman (U.S.G.S., Prof. Paper 191, 1939, p. 12) records 

 boueanum only from the Miocene and Pliocene of Europe. Brady's figures seem to be closest to Cushman's 

 figures of Nonion asterizans (Fichtel and Moll). 

 Figures 14, 15. — Nonion scaphum (Fichtel and Moll). 



Challenger Sta. 306, W. coast of Patagonia, E. Pacific. (345 fathoms) 

 Referred by Brady to Nonionina and by Cushman to Nonion. (A Nonionella?) 

 Figure 16. — Nonionella bradii (Chapman). 



Challenger Sta. 217A, off Papua, Pacific. (37 fathoms) 

 Referred by Brady to Nonionina scapha (Fichtel and Moll) and by Chapman (Brit. Antarctic Exped. 1907- 

 1909, Sci. Invest. Repts., Geol., Vol. 2, Pt. 3, 1917, p. 71) to Nonionina scapha var. bradii. It is regarded as 

 Nonionella, and unrelated to A^. scaphum. 

 Figures 17-19. — Nonionella turgida (Williamson). 



Figs. 17, 18. Porcupine Sta. 67-68, E. of Shetland, E. Atlantic. (64-75 fathoms) 

 Fig. 19. Challenger Sta. 167, W. coast of New Zealand. (150 fathoms) 

 Referred by Brady to Nonionina and by Cushman (U.S.N.M. Bull. 104, Pt. 7, 1930, p. 15) to Nonionella. 

 N. turgida occurs typically in the North Atlantic and it is possible that fig. 19 represents a different species 

 but Parr has noted that the New Zealand fauna has many species in common with that of the British Isles. 

 Figures 20, 21. — Elphidium orbidulare (Brady). 



Porcupine Sta. 57, Faroe Channel (cold area), N. Atlantic. (632 fathoms) 



*Galloway and Heminway (N.Y. Acad. Sci., Sci. Surv. Porto Rico, Vol. 3, Pt. 4, 1941, p. 357) referred these figures to Nonion nico- 

 barensis Cushman. Possibly figure 9 is that species but figure 8 is regarded as barleeanum. Boltovskoy (Micropaleontoiogy, Vol. 4, No. 2, 

 1958, pp. 193-198 and personal communication J regards most forms of this type as Nonion affine (Reuss) but does not refer to these 

 figures.
