EXPLANATION OF PLATE 93 (XCIII) 



Fig. 1, X 60; Figs. 2, 3, X 60-100; Figs. 4, 5, X 40; Figs. 6, 7, X 50; 

 Figs. 8, 9, X 50-60; Figs. 10, 11, X 55-60. 

 Figures 1, 4, 5. — Cibicides lobatulus (Walker and Jacob). 



Fig. 1. Challenger Sta. 354A, Vigo Harbor, Spain, Atlantic. (11 fathomc) 

 Fig. 4. Challenger Sta. 246, North Pacific. (2050 fathoms). 

 Fig. 5. Challenger Sta. 300, N. of Juan Fernandez, Pacific. (1375 fathoms) 

 Referred by Brady to Truncatulina and by Cushman and others to Cibicides. 

 Figure 2. — Parvicarinina altocamerata (Heron-Allen and Earland). 



Challenger Sta. 166, W. coast of New Zealand. (275 fathoms) 

 Referred by Brady to Truncatulina tenuimargo Brady, and transferred to Laticarinina tenuimargo (Brady), 

 with fig. 3, by Cushman (Bernice P. Bishop Mus., Bull. 119, 1934, p. 137). Heron-Allen and Earland (British 

 Antarctic "Terra Nova" Exped. 1910, Zool. Vol. 6, No. 2, 1922, p. 209) referred this figure to Truncatulina 

 tenuimargo var. altocamerata, and Finlay (Trans. Proc. Roy. Soc. New Zealand, Vol. 69, Pt. 1, 1940, p. 467) 

 made it the genotype of Parvicarinina as P. altocamerata (Heron-Allen and Earland). 

 Figure 3. — Cibicides tenuimargo (Brady). 



Challenger Sta. 174A, off Fiji, Pacific. (255 fathoms) 

 Referred by Brady to Truncatulina, and by Galloway and Wissler, with fig. 2, to Cibicides (Jour. Pal., Vol. 

 1, 1927, p. 66). Finlay (loc. cit. supra) restricted the name Cibicides tenuimargo (Brady) to figure 3, and re- 

 named figure 2 Parvicarinina altocamerata (Heron-Allen and Earland). 

 Figure 6. — Dyocibicides biserialis Cushman and Valentine. 



Challenger Sta. 166, W. coast of New Zealand. (275 fathoms) 

 Referred by Brady to Truncatulina variabilis d'Orbigny. Cushman and Valentine (Contr. Dept. Geol. 

 Stanford Univ., Vol. 1, No. 1, 1930, p. 30) erected the genus Dyocibicides for similar forms, with D. biserialis 

 as type. In 1931 Cushman (U.S.N.M. Bull. 104, Pt. 8, p. 126) referred T. variabilis of Brady, Parker and Jones 

 (not d'Orbigny) to D. biserialis, and Thalmann (Eclog. geol. Helv., Vol. 25, Pt. 2, 1932, p. 309) referred this 

 figure to that species. 

 Figure 7. — Dyocibicides uniserialis Thalmann. 



Referred by Brady to Truncatulina variabilis d'Orbigny and by Thalmann (Eclog. geol. Helv., Vol. 26, 

 No. 2, 1933, p. 254) to Dyocibicides uniserialis. 

 Figure 8. — Planulina bradii Tolmachofif. 



Porcupine Sta. 21, W. of Ireland, Atlantic. 

 Referred by Brady to Truncatulina wuellerstorfi (Schwager) and by Tolmachofif (Ann. Carnegie Mus., Pitts- 

 bugh, Vol. 23, 1934, p. 333) to Planulina bradii. This appears to be the same as Cibicides rugosa Phleger and 

 Parker (Mem. Geol. Soc. Amer., No. 46, 1951, p. 31). 

 Figure 9. — Planulina wuellerstorfi (Schwager). 



Challenger Sta. 166, ofif W. coast of New Zealand (275 fathoms) 

 Referred by Brady to Truncatulina and by Cushman (C.C.L.F.R., Vol. 5, 1929, p. 104) to Planulina. Hofker 

 (1. c, 1951) refers this species to Cibicides but gives no reason for dropping Planulina. 

 Figures 10, 11. — Planulina ariminensis d'Orbigny. (350 fathoms) 

 Challenger Sta. 122, S.E. of Pernambuco, Atlantic. 

 Referred by Brady to Anomalina but Cushman and others have reinstated Planulina d'Orbigny with ari- 

 minensis as the genotype.
