EXPLANATION OF PLATE 48 (XLVIII) 



Figs. 1, 2, 5, 6, X 25; Figs. 3, 4, 7, 8, X 30; Figs. 9-12, X 15; Fig. 13, X 100; Figs. 14-16, X 18; 

 Figs. 17, 18, X 30; Figs. 19-21, 25-31, X 40; Figs. 22-24, X 35; Figs. 32-37, X 20; Fig. 38, X 15. 

 Figures 1, 2, 5. — Martinottiella bradyana (Cusliman). 



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

 Referred by Brady to Clavulina communis d'Orbigny and by Cushman (C.L.F.R. Spec. Publ. No. 6, 1936, 

 p. 40) to Listerella bradyana. Thalmann (Amer. Midland Nat., Vol. 28, 1942, p. 457) has pointed out that Lis- 

 terella Cushman 1933 is a primary homonym of Listerella Jahn 1906, and proposed the name Schenckiella. 

 This species was transferred to Martinottiella by Cushman in 1947 (Cush. Lab. Foram. Res., Spec. Publ. 8A, 

 p. 50). 

 Figures 3, 4, 6, 7, 8. — Martinottiella communis (d'Orbigny). 

 Fig. 3. Challenger Sta. 24, West Indies. (390 fathoms) 

 Figs. 6-8. Challenger Sta. 323, South Atlantic. 

 Referred by Brady to Clavulina communis d'Orbigny and by Cushman (C. C.L.F.R., Vol. 9, 1933, p. 37) 

 to Martinottiella. In 1936 (C.L.F.R. Spec. Publ. No. 8, p. 148) Cushman placed Martinottiella in the synonymy 

 of Listerella (now Schenckiella, see above), but Thalmann (Amer. Midland Nat., Vol. 28, 1942, p. 457) has 

 pointed out that it should be regarded as valid, an opinion later accepted by Cushman and others. Notwith- 

 standing the fact that M. communis is the genotype of Martinottiella, however, Thalmann has referred these 

 figures to Schenckiella communis (Amer. Midland Nat., Vol. 28, 1942, p. 463) which has tended to increase the 

 confusion. 

 Figures 9-13. — Martinottiella nodulosa (Cushman). 



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

 Referred by Brady to Clavulina communis d'Orbigny and by Cushman (U.S.N.M. Bull. 104, Pt. 3, 1922, 

 p. 85) to C. communis var. nodulosa. In 1936 (Geol. Soc. Amer., Bull., Vol. 47, p. 428) Cushman transferred 

 this form to Listerella and raised it to specific rank. As noted under figs. 1, 2, 5, Listerella is pre-occupied and 

 Schenckiella was proposed to replace it. Cushman, however referred this species to Martinottiella in 1947 (Cush. 

 Lab. Foram. Res., Spec. Publ. 8A, p. 50). 

 Figures 14-16. — Pseudoclavulina serventyi (Chapman and Parr). 

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

 Referred by Brady to Clavulina parisiensis d'Orbigny. The large size and coarse texture, as well as the general 

 shape agree well with the original figure of Chapman and Parr (Jour. Roy. Soc. Western Australia, Vol. 21, 

 1935, p. 5, pi. i, fig. 7), but no reference is made to Brady. 

 Figures 17, 18. — Clavulina multicamerata Chapman. 



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

 Referred by Brady to Clavulina parisiensis d'Orbigny. Brady's figures agree well with those of Chapman 

 (Jour. Quekett Micr. Club, Ser. 2, Vol. 10, 1907, p. 127, pi. ix, fig. 5) and of Cushman (C.L.F.R. Spec. Publ. 

 No. 8, 1937, p. 24, pi. 3, figs. 13-16) and show the valvular tooth in the aperture which mark the genus Clavulina. 

 No reference is made to Brady's figures by either Chapman or Cushman. 

 Figures 19-21. — Pseudoclavulina humilis (Brady). 



Challenger Sta. 209, Philippine Islands. (95-100 fathoms) 

 Referred by Brady to Clavulina parisiensis var. humilis, and to Pseudoclavulina humilis (Brady) by Cushman 

 (C.L.F.R., Spec. Publ. No. 7, 1937, p. 116). 

 Figures 22-24. — Clavulina pacifica Cushman. 



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

 Referred by Brady to Clavulina angularis d'Orbigny and by Cushman to C. pacifica (Carnegie Inst. Wash- 

 ington, Publ. No. 342, 1924, p. 22). 

 Figures 25-31. — Clavulina difformis Brady. 



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

 Referred by Brady to C. angularis var. difformis and raised to specific rank by Cushman (U.S.N.M., Bull. 

 100, Vol. 4, 1921, p. 156). 

 Figures 32-38. — Cylindroclavulina bradyi (Cushman). 



Figs. 32, 34-38. Challenger Sta. 174C, Fiji, Pacific. (210 fathoms) 

 Fig. a. Kandavu, Fiji, Pacific. 

 Referred by Brady to Clavulina cylindrica Hantken, and by Cushman to Clavulina bradyi nov. (U.S.N.M., 

 Bull. 71, Pt. 2, 1911, p. 73). Placed in Liebusella by Cushman (C.L.F.R., Spec. Publ. No. 8, 1937, p. 169) 

 and again in Clavulina by Mrs. D. K. Palmer in 1938 (Mem. Soc. Cub. Hist. Nat., Vol. 12, No. 4, p. 290). 

 In 1952 it was made the genotype of Cylindroclavulina by Bermiidez and Key (Mem. Loo. Sci. Nat. La Salle, 

 Venezuela, Vol. 12, No. 31, p. 76).
