EXPLANATION OF PLATE 109 (CIX), CONTINUED 



Referred by Brady to Nonionina, and by Cushman (1. c. supra, 1930, p. 12) to Nonion. Loeblich and Tap- 

 pan (Smith. Misc. Coll., Vol. 121, No. 7, 1953, p. 102) have transferred the species to Elphidium on the wall 

 structure, nature of the aperture and indications of retral processes in some specimens. 

 Figure 22a. — Elphidiononion poeyanum (d'Orbigny). 

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



Referred by Brady to Polystomella striata punctata (Fichtel & Moll). Galloway and Wissler (Jour. Pal., Vol. 

 1, 1927, p. 83) referred figs. 22a and b to Themeon decipiens nov., later changed to T. granulosus since decipiens 

 was preoccupied by Costa. Asano (Jour. Geol. Soc. Japan, Vol. 35, 1938, p. 586) compared both figures with 

 Elphidium subgranulosum, but since Brady included poeyanum in synonymy with his striatopunctata, and 

 typical poeyanum occurs in material from Challenger Sta. 24, figure 22a is regarded as this species. Hofker 

 (Archiv. Neerl. Zool., Leiden, Vol. 8, 1951, p. 356) has proposed the genus Elphidiononion based on the canal 

 system, with E. poeyanum (d'Orbigny) as genotype. Ellis and Messina (Catalogue of Foraminifera, Suppl. 

 for 1953, No. 1) suggest that the genus is inadequately characterized and may be invalid. 

 Figure 22b. — Elphidium cf. kerguelenense Parr? 



Challenger Sta. 315A, Falkland Islands, S. Atlantic. (6 fathoms) 



Referred by Brady to Polystomella striatopunctata (Fichtel and Moll). Parr (B.A.N.Z. Antarctic Res. Exp. 

 1929-1931, Ser. B, Vol. 5, No. 6, 1950, p. 373) suggested that Brady's Kerguelen records of E. striatopunctata 

 were E. kerguelenense but did not refer to this figure. Heron-Allen and Earland (Discovery Repts., Vol. 4, 

 1932, p. 439) identified Falkland material of this type as Elphidium incertum (Williamson) and it is possible 

 that they were correct. (See below — fig. 23.) 

 Figure 23. — Eliphidium incertum (Williamson)? 



Challenger Sta. 46, North Atlantic. (1350 fathoms) 



Referred by Brady to Polystomella striatopunctata (Fichtel and Moll), but this figure was reproduced by 

 Cushman (U.S.N.M. Bull. 104, Pt. 7, 1930, pi. 7, fig. 5) as Elphidium incertum (Williamson), with no reference 

 to Brady in the text. Thalmann (Eclog. geol. Helv., Vol. 25, No. 2, 1932, p. 311) referred Brady's fig. 23 to 

 E. angulatum (Egger), a very different form from the Miocene of Germany. Heron-Allen and Earland (Dis- 

 covery Repts., Vol. 4, 1932, p. 439, pi. 16, figs. 22-23) have figured a very similar Falkland Islands form as 

 E. excavatum (Terquem) with the remark "Under this name Terquem separated the very common northern 

 type which Williamson had earlier figured admirably under the erroneous designation P. umbilicatula Walker 

 (and Boys) .... On the British Coasts, the species reaches its maximum development .... under estuarine 

 conditions." Both Williamson and Cushman show a different form from excavatum as figured by Heron-Allen 

 and Earland, though Terquem's figures show considerable variation. More recently Loeblich and Tappan 

 (Smith. Misc. Coll. Vol. 121, No. 7, 1953, pp. 100-102) have given a full discussion of E. incertum, unfortunately 

 without figures, and indicate the confusion concerning its identify. Hofker (Spolia Zool. Mus. Hauniensis, 

 Vol. 15, 1956, pi. 21, figs. 1-3) has shown yet a different form as Eliphidiononion incertum (Williamson). 

 From similarities of Brady's figure to the figures of Macfadyen 1932, and Phleger 1952 (see Loeblich and 

 Tappan, 1. c.) and the description of Williamson, it has been referred tentatively to E. incertum.

 Referred by Brady to Polystomella subnodosa (Miinster) and by Cushman (Carnegie Inst. Washington, 

 Publ. 311, 1922, p. 56) to P. advena. Cushman also reported this species from Samoa and in 1930 (U.S.N.M. 

 Bull. 104, Pt. 7, p. 25) transferred it to Elphidium.

 Referred by Brady to Polystomella and placed in Eliphidiella, as genotype, by Cushman (C.C.L.F.R., Vol.
