EXPLANATION OF PLATE 13 (XIII) 



Figs. 1, 2, X 50 ; Figs. 3-11, X 30; Figs. 12-15, X 50; Figs. 16-19, X 40; Figs. 20, 21, X 60; Fig. 22, X 40; 

 Fig. 23, X 200; Figs. 24, 25, X 75. 

 Figures 1, 2? — Articulina mayori Cushman. 



Challenger Sta. 33, off Bermuda, Atlantic. (435 fathoms) 

 Referred by Brady to A. conico-articulata (Batsch) and by Cushman (C.L.F.R. Spec. Publ. No. 10, 1944, 

 p. 14) to A. mayori Cushman. Fig. 2 may be the same form. 

 Figures 3-5. — Tubinella inornata (Brady). 



Challenger Sta. 149D, Kerguelen Island, S. Pacific. (20-60 fathoms) 

 Referred by Brady to Articulina funalis Brady var. inornata and by Rhumbler (Zool. Jahrb., Vol. 24, 1906, 

 p. 27) to Tubinella inornata (Brady). It was designated the genotype of Tubinella by Cushman in 1928. 

 Figures 6-11. — Tubinella funalis (Brady). 



Figs. 6, 7, 9, 11. Challenger Sta. 145, Prince Edward Is., S. Pacific. (50-150 fathoms) 

 Figs. 8, 10. Challenger Sta. 149D, Kerguelen Is., S. Pacific. (20-60 fathoms) 

 Referred by Brady to Articulina and by Rhumbler (1. c. supra, 1906) to Tubinella Wiesner (Die Foram., 

 Deutsche Sudpol. Exped., 1901-1903, Vol. 30 (Zool., Vol. 12), 1931, p. 67, 108) erected Tubinellina to include 

 funalis. This has been shown by Loeblich and Tappan (Smith. Misc. Coll., Vol. 128, No. 5, 1955, p. 19) to be 

 a synonym of Tubinella. 

 Figures 12, 13. — Puteolina bradyi (Cushman). 



Challenger Sta. 33, off Bermuda, Atlantic. (435 fathoms) 

 Referred by Brady to Peneroplis pertusus (Forskal) var. g {P. laevigatus of Karrer), and by Cushman 

 (U.S.N. M. Bull. 104, Pt. 7, 1930, p. 40) to P. bradyi'^ Hofker (Jour. Roy. Micr. Soc, Ser. Ill, Vol. 71, Pt. 4, 

 1952, p. 450) placed bradyi in Puteolina (genotype Peneroplis proteus d'Orbigny). 

 Figure 14. — Peneroplis carinatus d'Orbigny. 



Challenger Sta. 352A, Cape Verde Islands, Atlantic. (11 fathoms) 

 Referred by Brady to P. pertusus (Forskal) var. f {P. carinatus d'Orbigny), and by Cushman (U.S.N.M. 

 Bull. 104, Pt. 7, 1930, p. 36) to P. carinatus d'Orbigny. 

 Figure 15. — Peneroplis planatus (Fichtel and Moll). 



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

 Referred by Brady to P. pertusus (Forskal) var. a {P. planatus (Fichtel & Moll)) and by Cushman (U.S.N.M. 

 Bull. 100, Vol. 4, 1921, p. 481) to P. planatus (F. & M.). 

 Figures 16, 17, 23. — Peneroplis pertusus (Forskal). 



Fig. 16. Challenger Sta. 185A, Torres Strait, Pacific. (3-11 fathoms) 

 Fig. 17. Challenger Sta. 218A, Admiralty Islands, Pacific. (16-25 fathoms) 

 Referred by Brady to P. pertusus var. b, and by Cushman (1. c. supra, 1921, p. 481) to P. pertusus (Forskal). 

 Figures 18, 19, 22. — Spirolina arietina (Batsch). 



Figs. 18, 19. Challenger Sta. 218A, Admiralty Islands, Pacific. (16-25 fathoms) 

 Fig. 22. The Aegean Sea, Mediterranean. 

 Referred by Brady to Peneroplis pertusus var. c (P. arietinus (Batsch)), and by Cushman (U.S.N.M. Bull. 104, 

 Pt. 7, 1930, p. 43) to Spirolina arietinus (Batsch). 

 Figures 20, 21. — Spirolina acicularis (Batsch). 



Challenger Sta. 173A, off Fiji, Pacific. (12 fathoms) 

 Referred by Brady to Peneroplis pertusus var. d (P. cylindraceus (Lamarck)). Cushman (U.S.N.M. Bull. 

 161, Pt. 2, 1933, p. 63, pi. xix, figs. 6, 7) describes and figures very similar forms from the general region of the 

 Fiji Islands as S. acicularis (Batsch) but does not refer to Brady's figures. He suggests a possible relationship 

 with Monalysidium (see below). 

 Figures 24, 25 (?). — Monalysidium politum Chapman? 



Challenger Sta. 352A, Cape Verde Islands, Atlantic. (11 fathoms) 

 Referred by Brady to Peneroplis pertusus (Forskal) var. e {P. lituus (Gmelin)? and by Heron-Allen and 

 Earland (Trans. Zool. Soc. London, Vol. 20, 1915, p. 603) to Monalysidium polita Chapman (q.v. for full 

 discussion, pp. 594-601, 603-604). Chapman (Jour. Linn. Soc, Zool., Vol. 28, 1900, p. 3) suggests Brady's 

 figures resemble M. sollasi Chapman but Heron-Allen and Earland regard this form as Peneroplis. Hofker 

 (Jour. Roy. Micr. Soc, Vol. 71, 1951, p. 230) figures a form very similar to Brady's specimens as Dcndritina 

 elegans d'Orbigny, and shows politum Chapman as Dendritina {Monalysidium), which, he claims, is striate and 

 not pitted or punctate.
