Figs 1-4, X 30; Fig. 5, X 25; Fig. 6, X 40; Figs. 7-10, X 20; Fig. 11, X 60; Fig. 12, X 50; 

 Fig. 13, X 20; Fig. 14, X35; Fig. 15, X 20; Fig. 16, X 25; Figs. 17-19, X 40; Figs. 20, 21, X 70. 

 Figures 1-4. — Karreriella bradyi (Cushman). 



Figs. 1, 2, 3. Porcupine Sta. 42, S.W. of Ireland, Atlantic. (862 fathoms) 

 Fig. 2b. Challenger Sta. 224, North Pacific. (1850 fathoms) 

 Fig. 4. Challenger Sta. 300, N. of Juan Fernandez, Chile. (1375 fathoms) 

 Referred by Brady to Gaudryina pupoides d'Orbigny and to Gaudryina bradyi by Cushman (U.S.N.M. Bull. 

 71, Pt. 2, 1911, p. 67). Transferred to Karreriella by Cushman in 1937 (C.L.F.R. Spec. Publ. No. 8, p. 135). 

 Figures 5, 6?. — Textularia philippinensis Keijzer. 



Fig. 6. Challenger Sta. 279C, off Tahiti, Pacific. (620 fathoms) 



Referred by Brady to Gaudryina pupoides d'Orbigny var. chilostoma Reuss, and by Thalmann (Amer. Mid. 



Nat., Vol. 28, No. 2, 1942, p. 463) to Karreriella chilostoma (Reuss.) Keijzer (Leidse Geol. Med., Vol. 17, 1953, 



p. 271) examined similar material from Buton, Malaya, and found the species to be completely biserial. He 



named his species Textularia philippinensis and referred Brady's fig. 5 to his synonymy. Fig. 6 is doubtful. 



Figure 7. — Dorothia scabra (Brady). 



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

 Referred to Gaudryina by Brady and transferred to Dorothia by Cushman in 1937 (C.L.F.R. Spec. Publ. 

 No. 8, p. 98). 

 Figures 8-10. — Karreriella novangliae (Cushman). 



Porcupine Sta. 28, N.W. of Ireland, N. Atlantic. (1215 fathoms) 

 Referred to Gaudryina baccata Schwager by Brady and to G. baccata var. novangliae by Cushman in 1922 

 (U.S.N.M. Bull. 104, Pt. 3. p. 76). In 1937 (C.L.F.R. Spec. Publ. No. 8, p. 136) Cushman transferred it to 

 Karreriella and raised the variety to specific rank. 

 Figure 11.—? 



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

 Referred by Brady to Gaudryina baccata Schwager (see figs. 8-10, and note above). In view of the locality 

 it seems improbable that this is the same species as that figured in figs. 8-10. 

 Figure 12. — Dorothia exilis Cushman. 



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

 Referred by Brady to Gaudryina filiformis Berthelin, a Lower Cretaceous species. Cushman (U.S.N.M. Bull. 

 71, Pt. 2, 1911, p. 70) referred to "Gaudryina pseudofiliformis, new name — G. filiformis H. B. Brady (not G. fili- 

 formis Berthelin) Rep. Voy. Challenger, Zoology, Vol. 9, 1884, p. 380, pi. 46, figs. 12a-c" and cited two Pacific 

 records. In 1936 (C.L.F.R. Spec. Publ. No. 6, p. 30) he erected the species Dorothia exilis, with types from Chal- 

 lenger Sta. 24, cited the present figure of Brady, and noted that it was distinct from his earlier G. pseudofiliformis. 

 Unfortunately Thalmann (Amer. Mid. Nat., Vol. 28, No. 2, 1942, p. 403) read Cushman's reference of 1911 as 

 an indication that Brady's figure represented the type of G. pseudofiliformis sp. nov. (not nom. nov.), and that 

 as G. filiformis Brady (not Berthelin) had already been renamed, Dorothia exilis becomes a nomen deletum. 

 Loeblich and Tappan (personal communication) point out that the holotype of G. pseudofiliformis is Cush. Coll. 

 23758, from Albatross Sta. H-2923 (Pacific), and furthermore that Cushman himself pointed out the distinction 

 between the form figured here and his earlier G. pseudofiliformis. Dorothia exilis is therefore valid. 

 Figure 13. — Dorothia bradyana Cushman. 



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

 Referred by Brady to Gaudryina subrotundata Schwager and by Cushman to Dorothia bradyana (C.L.F.R., 

 Spec. Publ. No. 6, 1936, p. 31). 

 Figures 14-16. — Gaudryina (Pseudogaudryina) sp. nov. 



Fig. 14. Challenger Sta. 185, Torres Strait, Pacific. (155 fathoms) 

 Fig. 15. Challenger Sta. 174C, Fiji, Pacific. (210 fathoms) 

 Fig. 16. Challenger Sta. 162, Bass Strait, Pacific. (38-40 fathoms) 

 Referred by Brady to Gaudryina rugosa d'Orbigny, an Upper Cretaceous species from Europe. Brady's 

 Pacific specimens are more triangular in the later chambers than G. rugosa, and in form tend to approach the 

 Atlantic species G.i Pseudogaudryina) altantica (Bailey) but are somewhat more elongate and much coarser 

 in te.xture. They may prove to be a variety of G. collinsi Cushman. 

 Figures 17-19. — Karreriella { Karrerulina) apicularis (Cushman). 



Fig. 17. Challenger Sta. 218, North of Papua, Pacific. (1070 fathoms) 

 Figs. 18, 19. Challenger Sta. 346, South Atlantic. (2350 fathoms) 

 Referred by Brady to Gaudryina siphonella Reuss. In 1911 Cushman (U.S.N.M. Bull. 71, Pt. 2, p. 69) re- 

 ferred Brady's figures to Gaudryina apicularis "non. nov." In 1937 (C.L.F.R. Spec. Publ. No. 8) he trans- 

 ferred this species to Plectina Marsson. Finlay (Trans. Proc. Roy. Soc. New Zealand, Vol. 69, Pt. 4, 1940, 

 p. 450) made apicularis the type of his new subgenus Karrerulina, characterized by the terminal aperture. 

 Figures 20, 21. — Chrysalidinella dimorpha (Brady). 



Fig. 20. Challenger Sta. 205A, Hong Kong, Pacific. (7 fathoms) 

 Fig. 21. Challenger Sta. 260A, Honolulu, Pacific. (40 fathoms) 

 Referred by Brady to Chrysalidina and made the genotype of Chrysalidinella by Schubert in 1907 (Neues 

 Jahrb. f. Min., Pal., Vol. 25, p. 242).
