 Referred by Brady to L. semistriata Williamson and by Buchner (Nova Acta Leopoldina, n.f.. Vol. 9, No. 

 62, 1940, p. 418) to L. laevis (Montagu) but with no reference to fig. 18, which is queried by Brady.

 Figure 20. — Lagena sidebottomi Ear land. 



Challenger Sta. 276, North of Tahiti, Pacific. (2350 fathoms) 

 Referred by Brady to an intermediate between L. crenata and L. semistriata ; by Cushman (U.S.N.M. Bull. 

 71, Pt. 3, 1913, p. 29) to L. intermedia Sidebottom, and by Earland (Discovery Repts., Vol. 10, Foraminifera 

 Pt. Ill, 1934, p. 161) to L. sidebottomi, nom. nov. for L. intermedia Sidebottom 1912, non Rzehak. 

 Figures 19, 28. — Lagena striata (d'Orbigny)? 



Fig. 19. Challenger Sta. 185, Torres Strait, Pacific. (155 fathoms) 

 Fig. 28. Challenger Sta. 285, South Pacific. (2375 fathoms) 

 Included by Brady in L. striata but not by Buchner (Nova Acta Leopoldina, n. f.. Vol. 9, No. 62, 1940, p. 

 424) who refers only to figs. 22, 24 of Brady. 

 Figures 22, 24. — Lagena striata (d'Orbigny). 



Fig. 22. Challenger Sta. 217A, Papua, Pacific. (37 fathoms) 

 Fig. 24. Challenger Sta. 232, South of Japan, N. Pacific. (345 fathoms) 

 Figures 23, 25-27. — Lagena laevis (Montagu) variants. 



Figs. 23, 25. Challenger Sta. 1491, Kerguelen Islands, S. Pacific. (120 fathoms) 

 Fig. 26. Challenger Sta. 191A, Ki Islands, Pacific. (580 fathoms) 

 Fig. 27. Challenger Sta. 218, N. of Papua, Pacific. (1070 fathoms) 

 Referred by Brady to Lagena sulcata (Walker and Jacob) (figs. 23, 26) and to L. sulcata var. interrupta 

 Williamson (figs. 25, 27), and by Buchner (Nova Acta Leopoldina, n. f.. Vol. 9, 1940, p. 419) to L. laevis (Mon- 

 tagu) variants. O. L. Bandy (Bull. Amer. Pal., Vol. 32, No. 131, 1949, p. 57) has referred fig. 23 to L. sulcata var. 

 spirata (M. Eocene, Mississippi), and this may prove to be valid. In view of the great variation in Lagena 

 laevis postulated by Buchner it is thought preferable to retain his classification here, but further study of the 

 Lagenidae will probably require many taxonomic changes, and many of the identifications given here must be 

 regarded as provisional only. 

 Figures 29, 30. — Lagena advena Cushman. 



Fig. 29. Challenger Sta. 338, South Atlantic. (1990 fathoms) 

 Fig. 30. Challenger Sta. 346, South Atlantic. (2350 fathoms) 

 Referred by Brady to L. striata d'Orbigny and in part (fig. 30) to L. advena by Cushman (U.S.N.M. Bull. 

 104, Pt. 4, 1923, p. 6). 

 Figure 31. — Lagena sp. nov. (1). 



Challenger Sta. 151, off Heard Island, S. Pacific. (75 fathoms) 

 Referred by Brady to L. acuticosta Reuss. Brady was followed by most later authors in this determination, 

 but Matthes (Palaeontogr., Vol. 90, Abt. A, 1939, p. 58) referred this figure, also fig. 32, and pi. 58, fig. 21, to 

 L. elegantissima (Bornemann, 1855), an Oligocene species. Figures of Recent specimens referred to L. acuti- 

 costa by Cushman, Sidebottom, Buchner and others agree fairly well with this figure of Brady but in the opinion 

 of the writer these do not represent the fossil form described by Reuss, nor that of Bornemann. It is regarded 

 as representing a new species. 

 Figure 32. — Lagena elegantissima (Bornemann)? 



Challenger Sta. 276, South Pacific. (2350 fathoms) 

 Referred by Brady and later authors to L. acuticosta Reuss. Matthes (1. c. supra, 1939, p. 58) referred this 

 figure to L. elegantissima (Bornemann) and cited figures from Silvestri (Mem. Pont. Accad. Rom. N. Lincei, 

 Vol. 19, 1902, p. 155, figs. 46-49) which agree fairly well with that of Brady. Bornemann's figure shows a number 

 of differences and the south Pacific form may belong to a new species. 

 Figures 33, 34. — Lagena sulcata (Walker and Jacob). 



Fig. U. Challenger Sta. 271, South Pacific. (2425 fathoms) 

 Fig. 34. Challenger Sta. 149D, Kerguelen Islands, S. Pacific. (20-60 fathoms) 

 Brady and Parr (B.A.N.Z. Antarctic Res. Exped., 1929-1931, Ser. B, Vol. 5, Pt. 6, 1950, p. 301) also refer
