EXPLANATION OF PLATE 96 (XCVI) 



Figs. 1, 8, X 70; Fig. 2, X 28; Fig. 3, X 90; Figs. 4-7, 9-14, X 100. 

 Figure 1. — Discorbina rosea (d'Orbigny). 

 Shore sand, Cuba. 

 Referred by Brady to Truncatulina rosea (d'Orbigny) and by Cushman and others to Rotalia. Bandy (Jour. 

 Pal., Vol. 18, 1944, p. 372) placed it in Rotorbinella, but Hornibrook and Vella (The Micropal., N. Y., Vol. 8, 

 No. 1, 1954, p. 26) have given reasons for the retention of the name Discorbina Parker and Jones with Rotor- 

 binella in synonymy. Hofker (Spolia Zool. Mus. Hauniensis, Vol. 15, 1956, p. 76) has recently figured "Parrelln 

 rosea (d'Orbigny)" from off Santa Cruz Is., West Indies. He states that specimens received from Bermudez 

 as Rotorbinella rosea (d'Orbigny) show a straight, nearly umbilical aperture, whereas his material shows the 

 aperture of Parrella. Material from shore sand of Cuba (near topotype for d'Orbigny's species), Tampico beach 

 and Barbados has been examined and all shows the straight, nearly umbilical aperture as indicated by Brady's 

 figure. It is therefore concluded that Hofker's species, if truly a Parella, is not d'Orbigny's rosea, but a new 

 species. 

 Figure 2. — Cibicides margaritiferus (Brady). 



Challenger Sta. 209, Philippines, Pacific. (95-100 fathoms) 

 Referred by Brady to Truncatulina and by Thalmann (Eclog. geol. Helv., Vol. 25, No. 2, 1932, p. 309) to 

 Rotalia. Specimens identical with Brady's figure from Sta. 209 and from off New Guinea show a typical Cibicides 

 aperture and the species has therefore been placed in that genus. 

 Figure 3. — Osangularia bengalensis (Schwager). 



Challenger Sta. 191A, Ki Islands, Pacific. (580 fathoms) 

 Referred by Brady to Truncatulina cutter (Parker and Jones) but Chapman and Parr (Australasian Ant- 

 arctic Exped. 1911-1914, Ser. C, Vol. 1, Pt. 2, 1937, p. 119) have pointed out that Brady's form from the Pacific 

 is Anomalina bengalensis Schwager. Finlay (Trans. Roy. Soc. N.Z., Vol. 68, 1939, p. 523) erected the genus 

 Parrella with A. bengalensis Schwager as genotype, but since Parrella had been used by Ginsburg in 1938, 

 Osangularia Brotzen 1940 must be used for this species (see Thalmann and Graham, Contr. Cush. Found. 

 Foram. Res., Vol. 3, Pt. 1, 1952, p. 31). 

 Figure 4. — Siphoninella soluta (Brady). 



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

 Referred by Brady to Truncatulina and by Cushman (C.C.L.F.R., Vol. 3, Pt. 1, 1927, p. 77) to Siphoninella 

 as the genotype. 

 Figures 5-7. — Siphonina tubulosa Cushman. 



Fig. 5. Challenger Sta. 162, Bass Strait, Pacific. (38-40 fathoms) 

 Figs. 6, 7. Challenger Sta. 174A, ofi^ Fiji, Pacific. (255 fathoms) 

 Referred by Brady to Truncatulina reticulata (Czjzek) and by Cushman (Carnegie Inst. Washington, Publ. 

 342, 1924, p. 40) to Siphonina tubulosa. 

 Figure 8. — Siphonina bradyana Cushman. 



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

 Referred by Brady to Truncatulina reticulata (Czjzek) and by Cushman (U.S.N.M. Proc, Vol. 72, Art. 20, 

 1927, p. 11) to Siphonina bradyana. 

 Figures 9-14. — Siphoninoides echinata (Brady). 



Fig. 9. Challenger Sta. 185, Torres Strait, Pacific. (155 fathoms) 

 Figs. 10, 13, 14. Challenger Sta. 260A, off Honolulu, Pacific. (40 fathoms) 

 Figs. 11, 12. Challenger Sta. 219A, Admiralty Islands, Pacific. (17 fathoms) 

 Referred by Brady to Truncatulina and by Cushman (C.C.L.F.R., Vol. 3, No. 1, 1927, p. 77) to Siphoni- 

 noides, as the genotype.
