figs. 23 and 26 to this species but Buchner does not agree with this (1. c. supra), and the figures seem to bear 

 him out.

 Pt. 6, p. 308) to Fissurina.

 Brady referred Figs. 4, 17? and 18 to apiculate forms of L. sulcata (Walker and Jacob) and figs. 5, 6 to L. 

 sulcata var. interrupta Williamson, apiculate forms. Some confusion exists among subsequent authors. Silvestri 

 (Mem. Pont. Ace. Nuovi Lincei, Vol. 19, 1902, p. 163) referred fig. 4 to L. lyelli (Seguenza 1862) and figs. 5 

 and 6 to broken chambers of Nodosaria scalaris var. separans Brady. This last opinion is seriously questioned, 

 though figs. 4-6 may well be L. lyelli or variants of that species. Cushman (U.S.N.M. Bull. 71, Pt. 3, 1913, p. 

 23) referred figs. 4, 17? to L. sulcata var. apiculata, a homonym of L. apiculata (Reuss). Cushman and Mc- 

 Culloch (Allan Hancock Pacific Exped., Vol. 6, No. 6, 1950, p. 360) renamed the variety L. sulcata var. spicata 

 though no mention is made of L. lyelli and the views of Silvestri. The identity of fig. 18 remains highly un- 

 certain but it seems probable that the remaining figures represent either variants of L. lyelli (Seguenza) or 

 L. sulcata var. spicata Cushman and McCulloch with the possibility that the two are synonymous. 

 Figures 11-15. — Lagena distoma Parker and Jones MS., Brady. 



Fig. 11. Challenger Sta. 1491, Kerguelen Islands, S. Pacific. (120 fathoms) 

 Figs. 12-15. Porcupine Sta. 67-68, E. of Shetlands, N. Atlantic. (64-75 fathoms) 

 Figure 16. — Lagena distoma-margaritifera Parker and Jones. 



Challenger Sta. 162, Bass Strait, Pacific. (38-40 fathoms) 

 Figure 19. — Lagena meridionalis Wiesner. 



Challenger Sta. 145, Prince Edward Island, S. Pacific. (50-150 fathoms) 

 Referred by Brady to L. gra«7w Williamson and by Wiesner (Foram. Deutsche Siidpolar Exped. 1901-1903, 

 1931, p. 117) to L. gracilis var. meridionalis. Raised to specific rank by Loeblich and Tappan (Smiths. Misc. 

 Coll., Vol. 121, No. 7, 1953, p. 59). 

 Figure 20. — Lagena sp. nov. (2) 



Challenger Sta. 241, North Pacific. (2300 fathoms) 

 Referred by Brady to L. acuticosta Reuss but it has little in common with that species and from a survey of 

 the available literature it appears to be new. 

 Figure 21. — Lagena sp. nov.? 



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

 Referred by Brady to L. acuticosta Reuss. Matthes (1. c. antes, 1939, p. 58) has referred this figure to L. 

 elegantissima (Bornemann) and Loeblich and Tappan (Smith. Misc. Coll., Vol. 121, No. 7, 1953, p. 59) to L. 

 apiopleura. They cite Brady, pi. 58, fig. 2 (not pi. 57, figs. 31, 32, and not pi. 58, fig. 20), but their "fig. 2" 

 is an error for fig. 21 (personal communication). Loeblich and Tappan figure a form with incipient reticulate 

 ornamentation at the upper end of the test, below the aperture, but do not indicate this feature in their de- 

 scription. Their figure of L. apiopleura suggests that they are dealing with Oolina williamsoni (Alcock), with 

 which should probably be included Oolina tasmanica Parr. Brady's fig. 21 is closely related to this form but does 

 not show the reticulate portion between the longitudinal ribs and the smooth apertural collar. It may prove 

 to be a distinct species, or a variety of Oolina williamsoni. Until examination of actual material shows the 

 presence of an internal tube it is regarded as preferable to leave it provisionally in Lagena. 

 Figures 22-24. — Lagena gracilis Williamson. 



Figs. 22, 23. Challenger Sta. 276, North of Tahiti. (2350 fathoms) 

 Fig. 24. Challenger Sta. 271, South Pacific. (2425 fathoms) 

 Buchner (1. c. supra, 1940, p. 426) includes fig. 19 in this species, but excludes fig. 22 and queries fig. 24.
