EXPLANATION OF PLATE 12 (XII) 



Figs. 1-4, X 50; Fig. 5, X 30; Figs. 6-24, X 50. 

 Figures 1-4. — Planispirinella exigua Brady. 



Figs. 1, 2, 4. Challenger Sta. 187A, off Booby Island, Pacific. (8 fathoms) 

 Fig. 3. Challenger Sta. 185, Torres Strait, Pacific. (155 fathoms) 

 Referred to Planispirina by Brady; made the type of Planispirinella by Wiesner (Deutsche Siidpol. Exped. 

 1901-1903, Vol. 20, 1931, p. 69). 

 Figures 5, 7, 8. — Hauerinella inconstans (Brady). 



Fig. 5. Challenger Sta. 120, off Pernambuco, W. Atlantic. (675 fathoms) 

 Figs. 7, 8. Challenger Sta. 24, West Indies. (390 fathoms) 

 Referred by Brady to Ophthalmidium, and by Schubert (Pal. Zeitschr., Vol. 3, 1920, p. 162) to Hauerinella 

 gen. nov., as genotype. Cushman ('Foraminifera . . . ,' 1928, and subsequently) placed Hauerinella in synonymy 

 of Ophthalmidium, and Macfadyen (Jour. Roy. Micr. Soc, Vol. 59, 1939, p. 165) gave tacit agreement to this 

 view by listing inconstans as Ophthalmidium. Wood and Barnard, however (Q.J.G.S., London, Vol. 102, 1946, p. 

 85), in a restudy of this group and Brady's types, reinstated Hauerinella, and designated fig. 5 of Brady as 

 the holotype. 

 Figure 6. — Hauerinella tumidulum (Brady). 



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

 Referred by Brady to Ophthalmidium. Cushman (U.S.N.M., Bull. 104, Pt. 6, 1929, p. 89) placed tumidulum 

 in synonymy with H. inconstans (Brady), as Ophthalmidium, and was followed by Thalmann. Macfadyen 

 (1. c. supra, 1939, p. 165) listed tumidulum as a valid species of Ophthalmidium, with no reference to Hauerinella. 

 Wood and Barnard, as noted above, have reinstated Hauerinella as valid, and tumidulum, which is regarded 

 as distinct from inconstans has been placed in that genus. 

 Figures 9-11. — Vertebralina insignis Brady. 



Challenger Sta. 172, Friendly Islands, Pacific. (18 fathoms) 

 Figures 12, 13. — Articulina pacifica Cushman. 



Challenger Sta. 260A, off Honolulu reefs. Pacific. (40 fathoms) 

 Referred by Brady to A. sulcata Reuss, a fossil species, and by Cushman (C.L.F.R., Spec. Publ. No. 10, 

 1944, p. 17) to yl. pacifica. 

 Figures 14-16. — Vertebralina striata d'Orbigny. 



Fig. 14. Challenger Sta. 187, S. of New Guinea, Pacific. (6 fathoms) 

 Figs. 15, 16. Challenger Sta. 187A, Torres Strait, Pacific. 

 Figures 17, 18. — Articulina sagra d'Orbigny. 



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

 Referred by Brady to A. conico-articulata (Batsch), a form of doubtful characteristics originally recorded 

 from Rimini. Cushman (C.L.F.R. Spec. Publ. No. 10, 1944, p. 11) refers these figures to .4. sagra d'Orbigny; 

 he also (1. c, 1944, p. 17) suggests that Batsch's name should be allowed to lapse, as unidentifiable. 

 Figures 19-21. — Articulina lineata Brady. 



Challenger Sta. 33, off Bermuda, Atlantic. (435 fathoms) 

 Figures 22-24. — Articulina pacifica Cushman? 



Fig. 22. Challenger Sta. 172, Friendly Islands, Pacific. (18 fathoms) 

 Figs. 23, 24. Challenger Sta. 260A, off Honolulu reefs. Pacific. (40 fathoms) 

 Referred by Brady to A. sagra d'Orbigny. Although Cushman does not refer to these figures of Brady in 

 his study of Articulina (C.L.F.R. Spec. Publ. No. 10, 1944) his description and figures of .4. pacifica suggest 

 that that species is represented here (see also figs. 12, 13 on this plate).
