EXPLANATION OF PLATE 67 (LXVII), CONTINUED 



ful that this is the Upper Cretaceous species described by Reuss. It appears to be very close to Vaginulinopsis 

 tasmanica Parr (B.A.N. Z. Antarctic Res. Exped. 1929-1931, Ser. B, Vol. 5, No. 6, 1950, p. 324). 

 Figure 8. — Vaginulinopsis pacifica (Cushman and Hanzawa). 



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

 Referred by Brady to "anomalous specimen, probably the same species" (i.e. Cristellaria schloenbachi Reuss, 

 of Fig. 7). Cushmaa and Hanzawa (C.C.L.F.R., Vol. 12, Pt. 2, 1936, p. 47) nam^d this form Polymorphinella 

 pacifica. Thalmann (1933, Eclog. geol. Helvet., Vol. 26, No. 2, p. 252) placed this, with fig. 7, in Astacolus 

 schloenbachi but later followed Cushman and Hanzawa. Parr (1. c. supra, 1950, p. 325) transferred the species 

 to Vaginulinopsis, regarding Polymorphinella as an irregular, abnormal, development of a single species of 

 Vaginulinopsis. 

 Figure 9. — Saracenaria italica Defrance var. volpicelli (Costa). 

 Challenger Sta. 335, S. Atlantic. (1425 fathoms) 

 Referred by Brady to Cristellaria. 

 Figures 10-12. — Vaginulina americana Cushman. 



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

 Referred by Brady to V. linearis (Montagu) and by Cushman (U.S.N.M., Bull. 104, Pt. 4, 1923, p. 135) 

 to V. americana. 

 Figures 13, 14. — Vaginulina spinigera Brady.

 Fig. 14. Porcupine Sta. 23, N.W. of Ireland, Atlantic. (630 fathoms) 

 Figures 15, 16. — Vaginulina patens Brady. 



Challenger Sta. 209, Phillipines. (95-100 fathoms) 

 Thalmann (Eclog. geol. Helvet., Vol. 25, No. 2, 1932, p. 305) placed this species in Planularia but Parr 

 (B.A.N.Z. Antarctic Res. Exped. 1929-1931, Ser. B, Vol. 5, No. 6, 1950, p. 326) returned it to Vaginulina. 

 Figure 17. — Astacolus insolitus (Schwager). 



Challenger Sta. 192, Ki Islands, Pacific. (129 fathoms) 

 Referred by Brady to Cristellaria crepidula (Fichtel and Moll) and by Galloway and Heminway (N.Y. 

 Acad. Sci., Sci. Surv. Porto Rico, etc.. Vol. 3, Pt. 4, 1941, p. 334) to Astacolus insolitus (Schwager). 

 Figure 18. — Astacolus sp. nov. afT latus (Brady) non (Cornuel), Thalmann. 

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

 Referred by Brady to Cristellaria lata (Cornuel) but regarded as Astacolus sp. nov. by Thalmann (Eclog. 

 geol. Helvet., Vol. 25, No. 2, 1932, p. 305). 

 Figure 19. — Astacolus sp. nov. aff. crepidulus (Brady) non (Fichtel and Moll). 

 Challenger Sta. 75, off the Azores, Atlantic. (450 fathoms) 

 Referred by Brady to Cristellaria crepidula (F. & M.) but regarded by Thalmann (1. c. supra, 1932, p. 305) 

 as Planularia sp. nov. aff. crepidula, and later (1933) as Astacolus sp. nov. 

 Figure 20. — Astacolus crepidulus (Fichtel and Moll). 



Fig. 20a. Challenger Sta. 23, West Indies. (450 fathoms) 

 Fig. 20b. Challenger Sta. 33, off Bermuda. (435 fathoms) 

 Referred by Brady to Cristellaria crepidula (Fichtel and Moll) and by Thalmann (1. c. supra, 1932, p. 305) 

 to Robulus subarcuatulus (Williamson). Nautilus subarcuatulus was described by Walker and Jacob in 1798, 

 and according to Williamson (Recent Foraminifera of Great Britain, 1858, p. 29) includes Fichtel and Moll's 

 Cristellaria crepidula in synonymy, with the date 1803. It is evident from the original figures that subarcuatulus 

 is an entirely distinct species and Fichtel and Moll's crepidula is used here in accordance with common usage 

 of later writers.

 Fig. 4. Challenger Sta. 167, W. Coast of New Zealand. (150 fathoms) 

 Referred by Brady to Cristellaria tricarinella Reuss. Cushman (U.S.N. M. Bull. 100, Vol. 4, 1921, p. 230) 

 notes that Philippine specimens appear to differ from the figures of Reuss, and the species may be new. Chap- 

 man named similar forms Planularia australis ("Endeavor," Sci. Res., Vol. 3, Pt. 1, 1915, p. 24) and noted that 

 his specimens differed from Brady's figures in lacking the carination of the border. This is regarded as prob- 

 ably of varietal significance only. 

 Figures 5-9. — Planularia siddalliana (Brady). 



Challenger Sta. 174C, off Fiji, Pacific. (210 fathoms) 

 Referred by Brady to Cristellaria and by Thalmann (Eclog. geol. Helvet., Vol. 25, No. 2, 1932, p. 305) to 

 Planularia.
