EXPLANATION OF PLATE 4 (IV) 



Figs. 1, 2, X 20; Fig. 3, X 50; Figs. 4, 5, X 16; Fig. 6, X 50; Fig. 7, X 50; Fig. 8, X 27; 

 Fig. 9, X35; Fig. 10, X 40. 

 Figures 1, 2. — Planispirinoides bucculentus (Brady) var. placentiformis (Brady). 

 Fig. 1. Challenger Sta. 24, West Indies. (390 fathoms) 



Fig. 2. Challenger Sta. 149D, Kerguelen Islands, S. Pacific. (20-60 fathoms) 

 Referred by Brady to Miliolina and by Wiesner to Miliolinella. Parr (B.A.N.Z. Antarctic Res. Exped. 1929- 

 1931, Ser. B, Vol. 5, No. 6, 1950, p. 287) referred Miliolina bucculenta Brady to Planispirinoides, as genotype. 

 (See note to Plate CXIV). 

 Figure 3. — Miliolinella subrotunda (Montagu). 



Challenger Sta. 145, Prince Edward Island, S. Pacific. (50-150 fathoms) 

 Referred by Brady to Miliolina circular is (Bornemann), by Cushman and others to Triloculina, and by 

 Wiesner (Deutsche Sudpolar Exped. 1901-1903, Vol. 20 (Zool., Vol. 12), 1931, p. 107) to Miliolinella, as geno- 

 type. Parr in 1950 referred this species erroneously to Triloculina with no reference to Wiesner 's genus Milio- 

 linella. 

 Figures 4, 5. — Triloculina subvalvularis Parr. 



Fig. 4. Challenger Sta. 168, off New Zealand, Pacific. (1100 fathoms) 

 Referred by Brady to Miliolina valvularis (Reuss) and by Parr (B.A.N.Z. Antarctic Res. Exped. 1929-1931, 

 Ser. B, Vol. 5, No. 6, 1950, p. 296) to Triloculina subvalvularis. 

 Figure 6. — Triloculina transversestriata (Brady). 



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

 Referred by Brady to Miliolina and by Thalmann (1932) to Triloculina. 

 Figure 7. — Miliolinella sublineata (Brady). 



Challenger Sta. 218A, Admiralty Islands, Pacific. (16-25 fathoms) 

 Referred by Brady to Miliolina circularis (Bornemann) var. sublineata. Wiesner (1. c. supra, 1931, p. 108) 

 refers this figure to Miliolinella subrotunda (Montagu) var. sublineata (Brady), and Parr (1. c. supra, 1950, 

 p. 295) to Triloculina sublineata (Brady). 

 Figure 8. — Triloculina insignis (Brady). 



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

 Brady referred figs. 8 and 10 (see below) to Miliolina insignis Brady, but Cushman (U.S.N.M., Bull. 100, 

 Vol. 4, 1921, p. 458) referred fig. 8 to Pyrgo comata (Brady) (triloculine form) and fig. 10 to Triloculina in- 

 signis (Brady). In 1929 Cushman referred both figs. 8 and 10 to T. insignis. Thalmann (1932) referred fig. 8 

 to Flintina grata (Terquem) and Parr (Mining and Geol. Jour., Victoria, Vol. 2, No. 5, 1941, p. 305) restricted 

 the name insignis to fig. 8 and re-identified fig. 10 (see below). 

 Figure 9. — Flintina bradyana Cushman.* 



Challenger Sta. 233B, Japan. (15 fathoms) 

 Referred by Brady to Miliolina fichteliana (d'Orbigny) and by Cushman (U.S.N.M., Bull. 100, Vol. 4, 

 1921, p. 467) to Flintina bradyana (genotype of Flintina). 

 Figure 10. — Triloculina striatotrigonula Parker and Jones. 



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

 Referred by Brady to Miliolina insignis Brady and by Parr (Mining and Geol. Jour., Victoria, Vol. 2, No. 

 5, 1941, p. 305) to Triloculina striatotrigonula Parker and Jones 1865. 



*Note: Heron-Allen and Earland (Trans. Zool. Soc. London, Vol. 20, Pt. 17, 1915, p. 560) referred this figure to Miliolina webbiana 

 (d'Orbigny) {Triloculina 1839) and the similarity to d'Orbigny's figures of that Atlantic form is striking. Comparison with the types or 

 topotype material is indicated.
