EXPLANATION OF PLATE 95 (XCV) 



Figs. 1, 2, 7, X 30; Fig. 3, X 35; Fig. 4, X 50; Figs. 5, 9, 10, X 60; 

 Fig. 6, X 40; Fig. 8, X 100; Fig. 11, X 75. 

 Figures 1-3. — Cibicides praecinctus (Karrer). 



Fig. 1. Challenger Sta. 209, Philippines, Pacific. (95-100 fathoms) 

 Fig. 2. Challenger Sta. 217A, off Papua, Pacific. (37 fathoms) 

 Fig. 3. Challenger Sta. 219A, Admiralty Islands, Pacific. (17 fathoms) 

 Referred by Brady to Truncatulina. This species has been placed in the genus Eponides but material from 

 off Papua and the Malacca Straits which is identical with Brady's figures shows a typical Cibicides aperture. 

 Figure 4. — Cibicides robertsonianus (Brady). 



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

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

 Figure 5. — Cibicides bradyi (Trauth). 



Challenger Sta. 323, South Atlantic. (1900 fathoms) 

 Referred by Brady to Truncatulina dutemplei (d'Orbigny) and by Trauth (Denkschr. K. Akad. Wiss. Wien., 

 Math.— Nat. Kl., Vol. 95, 1918, p. 235) to Truncatulina bradyi. Thalmann (Amer. Mid. Nat., Vol. 28, No. 2, 

 1942, p. 464) transferred the species to Cibicides. Hofker (Siboga Exped. Foraminifera Pt. Ill, 1951, p. 359) 

 notes that this form is very similar to his C. hyalinea, although his figures do not bring out this similarity. 

 Figure 6. — Cibicidoides mundulus (Brady, Parker and Jones). 

 Challenger Sta. 296, South Pacific. (1825 fathoms) 

 Referred by Brady to Truncatulina sp., near T. haidingerii (d'Orbigny). It was referred to Cibicides mun- 

 dulus by Chapman and Parr (Australasian Antarctic Exped., 1911-1914, Ser. C, Vol. 2, Pt. 1, 1937, p. 120) 

 which was designated the type of Cibicidoides Thalmann 1939 (genus proposed by Brotzen, 1936, but not 

 valid until the genotype was designated by Thalmann (Jour. Pal., Vol. 13, 1939, p. 448). See discussion by Loeb- 

 lich and Tappan, Smiths. Misc. Coll., Vol. 128, No. 5, 1955, p. 25. 

 Figure 7. — Cibicides subhaidingerii Parr. 



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

 Referred by Brady to Truncatulina haidingerii (d'Orbigny) and by Parr (B.A.N.Z. Antarctic Res. Exped., 

 1929-1931, Ser. B, Vol. 5, No. 6, 1950, p. 364) to Cibicides subhaidingerii. 

 Figure 8. — Eponides tumidulus (Brady). 



Challenger Sta. 5, North Atlantic. (2740 fathoms) 

 Referred by Brady to Truncatulina and by Cushman (U.S.N.M. Bull. 104, Pt. 8, 1931, p. 55) to Eponides. 

 Cf. also Cibicides hyalinea Hofker (1. c. supra). 

 Figures 9-10. — Eponides bradyi Earland. 



Fig. 9. Challenger Sta. 64, North Atlantic. (2750 fathoms) 

 Fig. 10. Challenger Sta. 5, North Atlantic. (2740 fathoms) 

 Referred by Brady to Truncatulina pygmaea Hantken. Cushman (Bull. Scripps Inst. Oceanogr., Techn. 

 Ser., Vol. 1, 1927, p. 165) refers fig. 10 to Pulvinulinella bradyana, but Earland (Discovery Repts., Vol. 10, 

 Foraminifera Pt. Ill, 1934, p. 187) states that Brady's form is not a Pulvinulinella and therefore not conspecific 

 with bradyana, which he regards as a distinct W. American form. He names Brady's species Eponides bradyi. 

 Phleger, Parker and Peirson (Repts. Swedish Deep-Sea Exped. 1947-48, Vol. 7, Fasc. 1, 1954, p. 43) refer 

 Brady's figures to Epistominella (?) umbonifera (Cushman), with Earland's E. bradyi doubtfully in synonymy. 

 Their figures do not appear to be the same as those of Brady and indicate relationship with Pseudoparrella 

 and Epistominella. Earland's name has therefore been retained here. 

 Figure 11. — Eponides (?) tenera (Brady). 



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

 Referred by Brady to Truncatulina and by Cushman and others to Eponides. Hofker (Siboga Exped., Fora- 

 minifera Pt. Ill, 1951, p. 403) transfers it toGyroidina. Cushman, Todd and Post (U.S.G.S. Prof. Paper 260-H, 

 1954, p. 359) retain it in Eponides, but Parker (Bull. Mus. Comp. Zool., Harvard, Vol. Ill, No. 10, 1954, p. 

 530) regards it as a Pseudoeponides. This genus, described by Uchio in 1951, is characterized by supplementary 

 apertures on both the dorsal and the ventral side. Parker states that she has observed supplementary apertures 

 on the dorsal side of some specimens of E. tenera but such apertures could not be found by the writer on any 

 of the available Pacific material and the species has therefore been left tentatively in Eponides.
