 Figure 1. — Fissurina seguenziana (Fornasini)? 



Challenger Sta. VIII, off the Canaries, Atlantic. (620 fathoms) 

 Referred to Lagena orbignyana (Seguenza) by Brady, and so referred to by Buchner and most later authors. 

 Fornasini (Boll. Soc. Geol. Ital., Vol. V, 1886 (1887), p. 350) described L. seguenziana, based on Fissurina 

 marginata Seguenza, non Walker and Boys. Earland (Discovery Repts., Vol. 10, 1934, Foraminifera Pt. Ill, 

 p. 160) tentatively refers Brady's fig. 1 to this species. 

 Figures 2, 5. — Fissurina hispida (Reuss), compressed var. 



Fig. 2. Challenger Sta. 24, West Indies. (390 fathoms) 

 Fig. 5. Challenger Sta. 241, North Pacific. (2300 fathoms) 

 Referred by Brady to Lagena. 

 Figure 3. — Fissurina quadrata (Williamson). 



Porcupine Sta. 67-68, East of the Shetlands, Scotland (64-75 fathoms) 

 Referred by Brady to Lagena and by Williamson to Entosolenia. 

 Figure 4. — Lagena favoso-punctata Brady, compressed form. 



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

 See also PI. LVIII, fig. 35 and PI. LXI, fig. 2. Brady refers this species to Lagena but notes that it may be 

 ectosolenian or entosolenian, and here figures a compressed form. It therefore appears that some specimens show 

 characters of Lagena, and the present one of Fissurina. There may be several species confused, and that on 

 PI. LXI, fig. 2 has been referred to L. ampulla-distoma (Rymer Jones). 

 Figure 6. — Fissurina crebra (Matthes). 



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

 Referred by Brady to Lagena acuta Reuss (not typical) and by Earland (Discovery Repts., Vol. 10, Fora- 

 minifera III, 1934, p. 156) to L. marginata var. spinifera nov. Matthes (Palaeontogr., Vol. 90, Abt. A, 1939, 

 p. 72) referred this figure to L. crebra, apparently in ignorance of Earland's work, and Cushman (U.S.N.M. Bull. 

 71, Pt. 3, 1913, p. 8) to L. sacculus Fornasini, which is clearly erroneous since Fornasini states that his form 

 was not carinate (Mem. Ace. Sci. 1st. Bologna, Ser. V, Vol. 9, 1901, p. 49). Since spinifera Earland is a homonym 

 of L. aspera var. spinifera Chapman (P.Z.S., London, 1895, p. 27) Matthes' name is retained. 

 Figure 7. — Fissurina annectens (Burrows and Holland)? 



Challenger Sta. 332, South Atlantic. (2200 fathoms) 

 Referred by Brady to Lagena quadricostulata Reuss? See notes on Figure 15, this plate. Burrows and Holland 

 do not refer to this figure, therefore the identification is queried. 

 Figures 8-11. — Fissurina kerguelenensis Parr. 



Fig. 8. Challenger Sta. 151, Heard Island, S. Pacific. (75 fathoms) 

 Figs. 9, 10. Challenger Sta. 149D, Kerguelen Islands. (20-60 fathoms) 

 Fig. 11. Challenger Sta. 160, Southern Ocean. (2600 fathoms) 

 Referred to Lagena staphyllearia (Schwager) by Brady, and by Parr (B.A.N.Z. Antarctic Res. Exped., 1929- 

 1931, Ser. B, Vol. 5, No. 6, 1950, p. 305) to Fissurina kerguelenensis. 

 Figure 12. — Fissurina unguiculata (Brady). 



Challenger Sta. 332, South Atlantic. (2200 fathoms) 

 Referred by Brady to Lagena. 

 Figures 13, 14. — Oolina longispina (Brady), compresssed form. 

 Challenger Sta. 98, off West Africa. (1750 fathoms) 

 Referred by Brady to Lagena. This variant approaches a Fissurina. 

 Figure 15. — Fissurina annectens (Burrows and Holland). 



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

 Referred by Brady to Lagena quadricostulata Reuss and by Burrows and Holland (Monogr. Crag. Foram., 

 Pt. II, 1895, p. 203) to L. annectens. Millett (Jour. Roy. Micr. Soc, 1901, p. 495) refers this figure to L. fasciata 

 (Egger), with L. quadricostulata Reuss, in synonymy and no mention of annectens. Silvestri (Mem. Pont. 

 Accad. Nuovi Lincei, Vol. 19, 1902, p. 143) refers it to L. quadricostulata var. sexcostulata, again without men- 

 tion of annectens. 

 Figure 16. — Fissurina quadrata (Williamson) var. carinata Chapman. 



Challenger Sta. 135, Tristan d'Acunha, Atlantic. (100-150 fathoms) 

 Referred by Brady to L. quadrata (Williamson), partially carinate specimen. Chapman ("Subantarctic 

 Islands of New Zealand," Article 15, Rept. on the Foraminifera, 1909, p. 339) refers this figure to Lagena 

 quadrata (Williamson) var. carinata nov. 

 Figures 17, 19. — Fissurina semimarginata Reuss. 



Fig. 17. Challenger Sta. 145, Prince Edward Is., S. Pacific. (50-150 fathoms) 

 Fig. 19. Challenger Sta. 332, South Atlantic. (2200 fathoms) 

 Referred by Brady to Lagena marginata (Walker and Boys) var. semimarginata Reuss, and raised to specific 

 rank by Loeblich and Tappan (Smith. Misc. Coll., Vol. 121, No. 7, 1953, p. 78) as Fissurina semimarginata 

 (Reuss).
