EXPLANATION OF PLATE 107 (CVII) 



Fig. 1, X 30; Figs. 2-5, 8, 9, X 50; Figs. 6, 7, X 40. 

 Figure 1. — Streblus gaimardii (d'Orbigny) var. compressiuscula (Brady). 



Referred by Brady to Rotalia papulosa Brady var. compressiuscula. As noted under Streblus gaimardii on 

 Plate CVI, fig. 9, the name R. papulosa Brady (non d'Orbigny 1826) should be replaced by R. gaimardii 

 (d'Orbigny) and this form was placed in Streblus by Ishizaki in 1940. 

 Figure 2. — Streblus beccarii (Linnaeus) var. koeboeensis (LeRoy). 



Challenger Sta. 187A, Booby Island, Torres Strait, Pacific. (8 fathoms) 

 Referred by Brady to Rotalia beccarii (Linnaeus). Frizzell and Keen (Jour. Pal., Vol. 23, No. 1, 1949, p. 

 106) have pointed out that Brunnich cited Nautilus beccarii L. and Nautilus spirula L. for his genus Ammonia 

 in 1771, the name being regarded as probably valid by Winckworth 1945. This name has not as yet been vali- 

 dated by the International Committee on Zoological Nomenclature and Bermiidez and other authors have 

 retained Streblus Fischer 1817 for Nautilus beccarii and congeneric forms. Hammonium of Fichtel and Moll 

 1798 has also been used for N. beccarii but the validity of this also appears to be questionable. Until the matter 

 has been ruled upon by the Committee the name Streblus is adopted here. Brady's figure 2, although larger 

 than the variety proposed by LeRoy (Natuurk. Tijdschr. Nederl. — Indie, Vol. 99, Pt. 6, 1939, p. 255) is re- 

 garded as the same form. LeRoy does not refer to Brady's figure. 

 Figure 3. — Streblus cf. catesbyanus (d'Orbigny). 

 No locality given for this figure. 

 Referred by Brady to Rotalia beccarii (Linnaeus). Brady's figures closely resemble those of Rosalina cates- 

 byana d'Orbigny from Cuba, which was referred to Streblus by Bermiidez (Bol. de Geol., Min. de Minas, Cara- 

 cas, Vol. 2, No. 4, 1952, p. 72) although he does not refer to Brady's figures. 

 Figure 4. — Gyroidina broeckhiana (Karrer). 



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

 Referred by Brady to Rotalia and by Chapman and Parr (Australasian Antarctic Exped., 1911-1914, Sc. 

 Rep. Ser. C, Vol. 1, No. 2, 1937, p. 106) to Gyroidina. 

 Figure 5. — Streblus batavus Hofker? 



Porcupine Sta. 18, West of Ireland, Atlantic. (183 fathoms) 

 Referred by Brady to "Rotalia orbicularis (d'Orbigny)? (a passage-form between R. beccarii and R. or- 

 bicularis." Hofker (Siboga Exped., Foraminifera Pt. Ill, 1951, p. 501, etc.) referred North Sea material of 

 "Rotalia beccarii auct." to Streblus batavus. Brady's figures are close to some specimens found off Scotland which 

 appear to fit into the 5. batavus series. 

 Figures 6, 7. — Gyroidina neosoldanii Brotzen. 



Fig. 6. Challenger Sta. 302, South Pacific. (1450 fathoms) 

 Fig. 7. Challenger Sta. 246, North Pacific. (2050 fathoms) 

 Referred by Brady to Rotalia soldanii (d'Orbigny) and by Brotzen (Sver. Geol. Unders. Avh., Stockholm, 

 Ser. C, No. 396, p. 158) to Gyroidina neosoldanii. 

 Figure 8. — Notorotalia clathrata (Brady). 



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

 Referred to Rotalia by Brady and to Notorotalia by Finlay (Trans. Roy. Soc. New Zealand, Vol. 68, 1939, 

 p. 517). The species was emended by Parr (B.A.N.Z. Antarctic Res. Exped., 1929-1931, Ser. B, Vol. 5, No. 6, 

 1950, p. 374). 

 Figure 9. — Notorotalia patagonica Parr. 



Challenger Sta. 305, W. coast of Patagonia, E. Pacific. (120 fathoms) 

 Referred by Brady to Rotalia clathrata and by Parr (1. c. supra, 1950, p. 375) to Notorotalia patagonica.
